Heart Rate Monitors

Heart rate monitors used to be exclusively operated by physicians and nurses alone but that was soon rectified with todays multi-tasking generation. Every person seemed to want to know about everything that was related to them and that of course included monitoring their own heartbeats.

What is a Heart Monitor
Also known as a cardiac monitor, a heart monitor is a piece of electronic equipment that can be used to track or observe heart functions continuously. It allows people to place a numerical value on their healthiness based on their heart rate and have a target heart rate to work for. The more complex versions of the heart monitor allow physicians to see any signs of deterioration or improvement and make the necessary adjustments immediately.

Types of Heart Monitors
Today, heart monitors are produced by the millions and designed to cater specific types of individuals. Some heart monitors are primarily designed for weight loss programs while others are meant for the use of athletes or fitness programs. Some are wireless or come as a built-in feature of exercise equipment like a treadmill or an exercise bike. It can be strapped to your wrist or of considerable size. It may or may not emit any electromagnetic waves, depending on its purpose. A fetal heart monitor, for instance, must not produce any waves at all as this may affect the health of the baby.

Factors on Selecting the Best Heart Monitor for You

ECG-Accurate Monitors with Chest Straps Heart monitors that come with chest straps are more often not the most accurate of heart monitors. The chest strap is strapped around your chest, a few centimeters below your breast. It contains a device thats able to detect electrical activity of your heart and transmit it to the brain of the machine just like an ECG. The results are shown on the display monitor, which most of the times is attached to your wrist like a watch. Others however prefer results to be transmitted through audio messages via earphones.

Upon choosing heart monitors with chest straps, you need to remember to keep the strap constantly connected to your body lest you want the heart monitor to produce inaccurate readings.

Lastly, the only alternative against buying heart monitors with chest straps are the ones that rely on pulses on your fingertips. These however do not provide readings as accurate as those with chest straps.

Heart Monitor Features Basic and lower end models tend to display only your heart rate and maybe the elapsed exercise time as well. This of course does not provide sufficient information if you want to know exactly how much you need to improve before you can be qualified as a completely healthy individual. Higher end models will naturally offer a wider range of features for a price. Examples of such features are but not limited to heart rate zone alarms, timers and number of calories burned. It may also allow users to set pre-programmed workouts along with a targeted heart rate.

Ease of Use Lastly, you must purchase a heart rate monitor that you will have no problems of using. What good would a high end heart monitor do if it takes you an hour to operate it? Are the numbers and words appearing in the heart rate monitor readable? Can it be used in no-light situations? Are buttons well-labeled and ergonomically positioned?

To Buy or Not to Buy a Heart Monitor
Heart monitors can be especially costly, more so if you are intent on purchasing higher-end models. If you have a limited budget, you should ask yourself whether or not you truly need to buy a heart monitor. You can of course purchase one of the lower-end models but low quality heart monitors can lead to inaccurate results and that sort of defeats the purpose of buying one.

If you are intent on purchasing a heart monitor, you need to ask yourself another question: do you need to make a solo purchase or is it alright with you to use the heart monitor that comes as a built-in feature of a treadmill? Lastly, you should remember as well that you can always pay your doctor regular visits and have him monitor your heart rate for you.

FOOD POISONING

Introduction:

Food poisoning is an acute gastroenteritis caused by the consumption of a food material or a drink which contains the pathogenic micro organism or their toxins or poisonous chemicals.Food poisoning is common in hostels,hotels,communal feedings, and festivel seasons.

A group of persons will be affected with same type of symptoms ,and they give a history of consumption of a common food before few hours.

Types of food poisoning

1) Bacterial food poisoning:

Here the micro organisms called bacteria are responsible.The food material may contain the pathogenic bacteriae or their toxin and will be ingested along with the food.

2) Non bacterial food poisoning:

Due to the presence of toxic chemicals like fertilizers,insectisides,heavy metals and ect.

Since bacterial food poisoning is common it is discussed here.

Bacterial food poisoning:

All bacteria are not harmful.There are some pathogenic bacteria which secrete toxins and cause clinical manifestations.These organisms enter the human body through food articles or drinks.

How food poisoning occures:

1) Presence of bacteria in the water.

2) The raw materials for the food may contain toxins.

3) Premises where the food is prepared may contain micro organisms or toxins.

4) Food handlers may have some infectious diseases.

5) Some animals like dogs,rats may contaminate the food.

6) If prepared food is kept in the room temperature for a long time and heated again can make a chance for food poisoning.

7) Purposely some body mixing toxins in the food.


Some common bacterial food poisonings.

1) Salmonella food poisoning:

There are three different varieties of salmonella bacteria.(salmonella typhimurium,salmonella cholera suis,salmonella enteritidis) These bacteria are present in milk, milk products and eggs. Symptoms of this food poisoning include nausea, vomiting and diarrhoea. Fever is also common.

2) Botulism:

This is the dangerous type of food poisoning caused by clostridium botulinum. The spores of these organisms are seen in the soil and enters the human body through pickles and canned fish ect.Compared to other food poisonings here vomiting and diarrhoea are rare Mainly the nervous system is affected.The symptoms starts with double vision,numbness with weakness.Later there will be paralysis with cardiac and respiratory failure ending in death.

3) Staphylococcal food poisoning:

It is caused by staphylo coccus aureus. These organisms usually cause skin troubles like boils and eruptions.It causes mastitis in cow.Through the milk and milk products it enders and causes gastroenteritis.There will be vomiting,abdominal cramps with diarrhoea.

4) Closteridium food poisoning:

This is caused by closteridium perfringens.They are present in stool,soil and water. They enter the body through,meat,meat dishes and egg ect.If food articles are cooked and kept in room temperature for a long time and heated again before eating can result this food poisoning.Symptoms include vomiting ,diarrhoea and abdominal cramps.

5) Bacillus cereus:

The spores of these organisms can survive cooking and causes enteritis. Diarrhoea and vomiting is common in this infection.


How to investigate food poisoning?

1) Examine each and every person affected.

2) Water sample should be tested.

3) Kitchen, store room and food samples should be examined.

4) The cook and food handlers should be questioned and examined.

5) Samples of vomitus and stool of all victims should be tested to identify the bacteria.


How to prevent food poisoning:-

1) Only purified water should be used.

2) Hygiene should be maintained by all persons keeping contact with food.

3) Workers should use masks, cap and gloves during cooking and serving.

4) Sick individuals should not come in contact with food materials.

5) Kitchen and premises should be neat and clean.

5) Vessels should be washed with soap and hot water.

6) Should not keep the prepared food for a long time in room temperature.

7) All food materials should be kept in closed containers.

8) Animals like dog, cat, rat ect should not come in contact with food materials.

9) Vegetables should be washed before cooking.

10) Meat should be fresh and should be purchased from recognised slaughter house.

Exercise and Type 2 Diabetes

One of the most undemanding and the most workable ways to knock over blood sugar amount, eliminate the dangers of cardiovascular disease, and perk up health and welfare in general is exercise.

In spite of that, in todays inactive world where almost every indispensable job can be carried out online, from the ergonomic chair in front of a computer, or with a streaming line of messages from a fax machine, exercising can be a hard argument to win over.

The Weight of Exercise

Everyone should exercise, yet the health experts tells us that only 30% of the United States population gets the recommended thirty minutes of daily physical activity, and 25% are not active at all. In fact, inactivity is thought to be one of the key reasons for the surge of type 2 diabetes in the U.S., because inactivity and obesity promote insulin resistance.

The good news is that it is never too late to get moving, and exercise is one of the easiest ways to start controlling your diabetes. For people with type 2 diabetes in particular, exercise can improve insulin sensitivity, lower the risk of heart disease, and promote weight loss.

Type 2 Diabetes

Diabetes is on the rise. The number of people diagnosed with diabetes every year increased by 48% between 1980 and 1994. Nearly all the new cases are Type 2 Diabetes, or adult-onset, the kind that moves in around middle age. Symptoms of Type 2 Diabetes include increased thirst, appetite, and need to urinate; feeling tired, edgy, or sick to the stomach; blurred vision; tingling or loss of feeling in the hands.

The causes of type 2 diabetes are complex and not completely understood, although research is uncovering new clues at a rapid pace.

However, it has already been proven that one of the reasons for the boom in type 2 diabetes is the widening of waistbands and the trend toward a more deskbound and inactive lifestyle in the United States and other developed countries. In America, the shift has been striking; in the 1990s alone, obesity increased by 61% and diagnosed diabetes by 49%.

For this reason, health experts encourage those who already have type 2 diabetes to start employing the wonders that exercise can do for them. Without exercise, people have the tendency to become obese. Once they are obese, they have bigger chances of accumulating type 2 diabetes.

Today, the U.S. Department of Health and Human Services reports that over 80% of people with type 2 diabetes are clinically overweight. Therefore, it is high time that people, whether inflicted with type 2 diabetes or not, should start doing those jumping and stretching activities.

Getting Started

The first order of business with any exercise plan, especially if you are a dyed-in-the-wool sluggish, is to consult with your health care provider. If you have cardiac risk factors, the health care provider may want to perform a stress test to establish a safe level of exercise for you.

Certain diabetic complications will also dictate what type of exercise program you can take on. Activities like weightlifting, jogging, or high-impact aerobics can possibly pose a risk for people with diabetic retinopathy due to the risk for further blood vessel damage and possible retinal detachment.

If you are already active in sports or work out regularly, it will still benefit you to discuss your regular routine with your doctor. If you are taking insulin, you may need to take special precautions to prevent hypoglycemia during your workout.

Start Slow

For those who have type 2 diabetes, your exercise routine can be as simple as a brisk nightly neighborhood walk. If you have not been very active before now, start slowly and work your way up. Walk the dog or get out in the yard and rake. Take the stairs instead of the elevator. Park in the back of the lot and walk. Every little bit does work, in fact, it really helps a lot.

As little as 15 to 30 minutes of daily, heart-pumping exercise can make a big difference in your blood glucose control and your risk of developing diabetic complications. One of the easiest and least expensive ways of getting moving is to start a walking program. All you need is a good pair of well-fitting, supportive shoes and a direction to head in.

Indeed, you do not have to waste too many expenses on costly health club memberships, or the most up-to-date health device to start pumping those fats out. What you need is the willingness and the determination to start exercising to a healthier, type 2 diabetes-free life.

The results would be the sweetest rewards from the effort that you have exerted.

Exercise and Pregnancy

Prescribing a medication for pregnant women is a complex process.

Before obstetricians and gynecologists decide which dose of which drug can best treat a condition without putting any harmful side effects on the mother and the baby, they consider the patients age, general health, the number of months before delivery, tolerance for medications, and any other drugs the pregnant patient may be taking.

Prescribing exercise on pregnant women has to be just as scientific and precise. The type, intensity, frequency, and duration of a dose of exercise are all critical. One persons healthy, vigorous workout could be hazardous to another. These dangers may be greater in pregnant women because they are more likely to have strains and other serious side effects for the would-be mother.

However, if exercise will be implemented and carried out in a normal, average range, exercise will not have an effect on the overall condition of the pregnancy and especially on labor or delivery.

Pregnancy

Quality prenatal care should be given to a mother during her pregnancy. She should be prepared for the normal delivery of a healthy baby. Complications should be prevented at all costs.

All of these things are boiled down to the fact that a pregnant woman should be cared in such a way that she will not be compelled to do vigorous work but should not also stay in bed and be inactive until she gives birth to her baby.

Consequently, a pregnant womans condition varies in relation to the growth and development of the baby in side her womb. Therefore, it is necessary that proper health guidance be provided by her physician during her visit.

Moreover, it is important to keep the pregnant womans life active in order to promote good health, not only for her but also for the baby most importantly.

Physical conditions like blood pressure, weight and health status is usually monitored during the pregnant womans visit to her doctor. For this reason, it is significant to note that exercise can be the number one factor in order to keep these aspects in good condition.

As the health experts contend, adequate physical and emotional information is needed by a pregnant woman to prepare herself for delivery. She needs practical health messages in keeping herself and the baby healthy.

Hence, for mothers or would-be mothers who are not yet aware why they should exert some effort in engaging into moderate, normal exercise, here is a list of some of its benefits so that you will be able to understand the reason why pregnant women have to exercise regularly:

1. Defiance against fatigue

As muscle becomes fatigued, it produces less force. To accomplish a task like climbing the stairs, for example, or shoveling snow, more units of muscle must be called into play to back up the wearied muscles.

The tired muscles are both less efficient and less effective. Hence, this will just put more strain on the pregnant woman because of the weight that is continuously adding up each day. That is why tired muscles will usually result to leg cramps or sore muscles.

What every pregnant woman must know is that exercise improves the condition of the muscles and their ability to work longer without fatigue.

2. Reduce backaches

Even when you sit or stand, some muscles are working, and such relatively easy postures can tax some muscles and cause fatigue. The muscles of the lower back, for example, can be exhausted and worn out by the effort of keeping erect when a pregnant woman stand still for several hours.

With exercise, a pregnant woman can correct this error by developing her posture.

3. Increase the amount of oxygen

Work and exercise rely on glycogen, a substance produced by the body from complex carbohydrates and stored muscles and liver. The supply of glycogen in the muscles determines and limits the duration of activity. Exercise depletes the glycogen in the muscles and leads to tiredness.

However, when glycogen is depleted by strenuous activity, it is replaced in quantities greater than before, as if the body recognized the need to lay in a larger supply of fuel.

Hence, oxidation is essential for converting glycogen to the energy that pregnant women need to wiggle a finger, flex a muscle, or practice the lungs and heart for some blowing action during normal delivery.

These are just some of the many benefits exercise can bring to pregnant women. Besides, nothing is completely wrong for a pregnant woman doing some moderate exercises. The only important thing to remember is that before starting an exercise program, whether pregnant or not, it is best to consult your doctor. As they say, doctors know best!

Exercise and Hypertension

It seems as though many Americans are living a life that leads to high blood pressure or hypertension. As people age, the situation gets worse. Nearly half of all older Americans have hypertension. This disease makes people five times more prone to strokes, three times more likely to have a heart attack, and two to three times more likely to experience a heart failure.

The problem with this disease is that nearly one third of the folks who have hypertension do not know it because they never feel any direct pain. But overtime the force of that pressure damages the inside surface of your blood vessels.

However, according to experts, hypertension is not predestined. Reducing salt intake, adopting a desirable dietary pattern losing weight and exercising can all help prevent hypertension.

Obviously, quitting bad habits and eating a low fat diet will help, but the most significant part that you can do is to exercise. And just as exercise strengthens and improves limb muscles, it also enhances the health of the heart muscles.

Heart and Exercise

The exercise stimulates the development of new connections between the impaired and the nearly normal blood vessels, so people who exercise had a better blood supply to all the muscle tissue of the heart.

The human heart basically, supply blood to an area of the heart damaged in a myocardial infarction. A heart attack is a condition, in which, the myocardium or the heart muscle does not get enough oxygen and other nutrients and so it begins to die.

For this reason and after a series of careful considerations, some researchers have observed that exercise can stimulate the development of these life saving detours in the heart. One study further showed that moderate exercise several times a week is more effective in building up these auxiliary pathways than extremely vigorous exercise done twice as often.

Such information has led some people to think of exercise as a panacea for heart disorders, a fail-safe protection against hypertension or death. That is not so. Even marathon runners that have suffered hypertension, and exercise cannot overcome combination of other risk factor.

What Causes Hypertension?

Sometimes abnormalities of the kidney are responsible. There is also a study wherein the researchers identified more common contributing factors such as heredity, obesity, and lack of physical activity. And so, what can be done to lower blood pressure and avoid the risk of developing hypertension? Again, exercise seems to be just what the doctor might order.

If you think that is what he will do, then, try to contemplate on this list and find some ways how you can incorporate these things into your lifestyle and start to live a life free from the possibilities of developing hypertension. But before you start following the systematic instructions, it would be better to review them first before getting into action.

1. See your doctor
Check with your doctor before beginning an exercise program. If you make any significant changes in your level of physical activity particularly if those changes could make large and sudden demands on your circulatory system check with your doctors again.

2. Take it slow

Start at a low, comfortable level of exertion and progress gradually. The program is designed in two stages to allow for a progressive increase in activity.

3. Know your limit

Determine your safety limit for exertion. Use some clues such as sleep problems or fatigue the day after a workout to check on whether you are overdoing it. Once identified, stay within it. Over-exercising is both dangerous and unnecessary.

4. Exercise regularly

You need to work out a minimum of three times a week and a maximum of five times a week to get the most benefit. Once you are in peak condition, a single workout a week can maintain the muscular benefits. However, cardiovascular fitness requires more frequent activity.

5. Exercise at a rate within your capacity

The optimum benefits for older exercisers are produced by exercise at 40% to 60% of capacity.

Indeed, weight loss through exercise is an excellent starting point if you wan tot prevent hypertension. Experts say that being overweight is linked to an increased risk of developing hypertension, and losing weight decreases the risk.

Exercise and Cellulite

When Mike turned 65, he was 25 pounds overweight. By strict dieting, he shed the extra pounds, but he lost more weight; he also lost his energy and vitality. He was always exhausted, and his friends, seeing his gaunt, drawn face, worried about his health.

By the time volunteered for a particular fitness program two years later, he had put 25 extra pounds back on. After 6 months of exercise and some willpower at the dinner table, Mike slimmed down again. This time he felt better than he ever had, brimming with energy and glowing with good health.

What made the difference? The first time Mike lost weight; the second time he lost fat. The distinction is important. According to research, a large portion of the weight lost by dieting alone is active tissue, such as muscle and connective tissue, while a smaller fraction is excess fat. Exercise has the opposite effect. It increased his lean body mass and decreased his excess fat.

Same thing goes with cellulite. Most people tend to think that cellulites are only present to people who are obese. That is why they sometimes associate cellulite with fats and obesity.

Actually, even if cellulite refers to the chain of wrinkled fat cells and subcutaneous connective tissues beneath the layer of the skin, it should never be associated with people who are fat or obese. In fact, there are many people who have cellulite but are not fat at all.

In reality, nobody knows the main reason why some people accumulate cellulite. However, there are some factors that health experts are considering such as the structure of the fat cells or the poison that entered the body. Some experts say it may be caused by some hormonal changes in the body. But none of these things has been proven to cause cellulites.

However, the only main reason why most of the cellulite cases are abundant in women is that the connective tissues of women are more rigid and firm than men. Hence, whenever a woman gets fat, the fatty cells tend to swell and get bigger. It creates a protruding appearance to the skin producing an orange peel look.

For this reason, women are more prone to cellulite than men. That is why it is important for women to be more careful on their body as they have higher chances of accumulating cellulite.

Fats and Cellulite

With the many cases of obese people having cellulites in their body, most of them believed that their cellulites are caused by being too fat.

Even though not all those who are obese develop cellulites, being overweight can really trigger the development of cellulites. This is because too much fat under the skin tend to push the connective tissue creating a strain on the skin. Thus, cellulites form.

However, this is still dependent on the structure of the cells. If an individuals cell structure does not inhibit the tendency to bulge or expand even if fat deposits accumulate, then there will be no cellulites.

So, the most important thing to remember here is to keep those connective tissues firm and strong and avoid accumulating excess fats so as to avoid the development of cellulite.

How? Start an exercise routine program.

Transforming food into fat seems all too easy for most of us. Losing fat is far more difficult, and to accomplish this, we have only three alternatives: (1) decrease food intake and keep activity constant; (2) increase activity and keep food intake constant; or (3) combine both approaches: diet and exercise.

Physical activity can help reverse the results of inactivity. An hour of vigorous exercise burns up 300 to 600 calories. If you also cut 300 to 500 calories from your daily menu, you can also lose weight at the rate of one to two pounds a week.

Without exercise, you would have to eat 500 to 1,000 fewer calories a day to lose the same number of pounds in a week. Exercise is not for everyone who is over-fat, however. The severely obese person should exercise only under medical supervision to prevent strain on the cardiovascular system and connective tissue. And no one should restrict food intake drastically without consulting doctor.

Resorting to this kind of activity will only get the matter worse. Remember what happened to Mike? He thought that when he started dieting, he would eventually lose all the excess fats he has accumulated. The problem is that he lost those connective tissues rather than excess fat.

For people who are prone to cellulites, this will be a greater problem. Losing connective tissues instead of fat by strict dieting can only make the skin more prone to greater problems but the fat cells are still there. That only means that the problem is not solved at all.

Hence, if you wish to loose those cellulites, it would be better to loose those fats first. The idea here is to burn those fats by increasing your metabolism by 7.5% to 28% more than your normal rate.

It is for this reason that exercising is an important factor in losing cellulite. So for a more cellulite free body, always engage in an exercise routine.

Exercise and Arthritis

Your bones hang out in a lot of joints. Knee joints. Hip joints. The joints in your fingers and the joints in your toes.

Wherever bones meet, there is also cartilage, a rubbery, protective layer that ensures your joints bend smoothly and painlessly. But even cartilage cannot do this tremendous job alone. A thin membrane called the synovium provides fluid that lubricates the moving parts of the joint. When the cartilage wears out of the synovium becomes inflamed, the result is generally a case of osteoarthritis or rheumatoid arthritis.

In osteoarthritis, the cartilage can be eroded so much that bone does rub on bone. Thos type of arthritis develops gradually over a lifetime as a simple result of the wear and tear placed on your joints over the years. Very few people escape some degree of osteoarthritis, though the severity varies a great deal.

As a matter of fact, if you are over the age of 50, you are likely to have at least one joint affected by osteoarthritis. Osteoarthritis affects men and women equally and is by far the most common type of arthritis, with almost 16 million Americans in the list.

In rheumatoid arthritis, damage to the synovium is at the source of trouble. Doctors and researchers are not absolutely sure what causes it, but most think that rheumatoid arthritis is a disease in which the immune system actually attacks certain tissues in the body, including those that connect the joints and the synovium.

Rheumatoid arthritis begins with swollen, red, stiff, and painful joints, but it may progress until scar tissue forms in the joint or, in extreme cases, until the bones actually fuse together. Almost 75% of the 2 million people with rheumatoid arthritis in the United States are women. The disease can hit as early as teen years.

Exercising Your Prevention Options

Investing a little time in developing a good weight-bearing low-impact exercise and stretching plan can add up to great results when it comes to staving off arthritis pain. Strong muscles help protect the joints from wear and tear, and the movement keeps joints flexible.

That is why the quest for fitness is at hand, even if you are 50 years and over. However, most Americans over 50 are still right where they always were sitting back and watching others jog by. Most of them contend that that is just for people who have been athletic all their life, or some say exercise is for young people and engaging into exercise will do them more harm than good.

There are still some that insist on excusing their selves in exercise routines because they do not just have time or they have less energy than ever before. These are all lame excuses. Hence, it is time to start to get rid of those pains. Start exercising.

Consequently, preventing arthritis is not an exact science, but physicians have discovered a few ways to lower your risk. Here is how:

1. Do not weight around

The single most important measure anyone can take to prevent osteoarthritis of the knee is to lose weight if they are overweight. Extra weight puts extra stress on your knees. If you are 10 pounds overweight, for example, you put 60 pounds per square inch of extra pressure on your knees every time you take a step. That extra pressure can slowly but surely erode the cartilage in your knees, leading to arthritis.

A study has clearly supported the theory that weight loss weighs in on the side of prevention. In the study, overweight women who lost 11 pounds or more over a 10-year period decreased their risk of developing osteoarthritis of the knee by 50%.

2. Stretch those muscles

Any kind of stretching is good as long as you do not bounce, which can lead to a muscle pull. This is according to some of the professors of clinical medicine in New York City.

Try to hold a slow, steady stretch for 15 to 20 seconds, then relax and repeat. It is best to flex up by stretching before any exercise, especially running and walking. But it is also a good idea to stretch each day. Ask your doctor to teach you stretches that focus on potential arthritis trouble spots, such as the knees or the lower back.

3. Walking is always the best exercise

Take a good long walk at least three times a week or participate in a step-aerobics or low-impact exercise routine maximum results. There is no proof that running is bad for the joints, but remember, it may aggravate an injury if you already have one. Just remember to check with your doctor before starting a new exercise program.

The bottom line is that of all the healthful habits, exercise is the most important. This is because people are designed to be active. Hence, it is really important for people to exercise in order to stay healthy and keep those joints free from wear and tear.

Just keep in mind that the unexercised body, even if free from the symptoms of illness or problems like arthritis, is not at its full potential. Hence, start exercising right now!
