8 Health Myths You Should Be Aware Off!



1. A Heart Attack Is Generally Signaled By A Pain In The Left Side Of The Chest

This myth probably has its roots in the fact that the human heart, at its base, is sited slightly to the left of centre. Actually, the pain of a heart attack most, frequently originates in the centre of the chest. In fact, it is often mistaken for heartburn or indigestion, since in many cases it occurs after a heavy meal.

Starting from the centre of the chest, behind the breast bone, the pain can travel toward either or both shoulders, to the neck or lower jaw and down both arms to the hands. The victim generally turns pale, beings sweating profusely and may get a feeling of impending doom. The “pain” itself is more correctly described as a feeling of terrible constriction, a relentless squeezing rather than a sharp or throbbing pain.

As for pain in the left side of the chest, it’s likely to be due to more benign cause such as even pain arising out of nervousness. This kind of pain is generally of the stabbing/shooting/throbbing variety. And it usually stays where it starts; it does not travel all over the place! Pain in the left side of the chest can also arise from diseases or disorders of the pleura (the covering of the lung), the esophagus (food pipe), the stomach, the vertebral column, the gall bladder or even, rarely, the liver.

But the bottom line, of course is, don’t ignore any pain in the region of the chest. It may well innocuous; on the other hand, it may not.

2. If Raw Foods Are Always More Healthful Than Cooked Foods

Not always. When raw foods are analyzed under lab conditions, their nutritional credentials are indeed impressive. But, in effect, you may benefit more from the same food after it is lightly cooked. Here’s how:

Raw foods may be packed with nutrients, but some of them are not “available” to us in the raw state. Cooking ruptures the cellulose cell walls in the food, releasing “locked-in” nutrition, making it more accessible to us. In many cases, cooking “pre-digests” the food to a certain extent, bringing it to a form that the human body can digest and absorb. For instance, the beta carotene from carrots (making headlines these days because of its growing reputation as a cancer fighter) is better absorbed from cooked carrots than from raw.

Even if the food is digestible in its raw state, there could be another hitch. Some, raw foods contain “anti-nutrients”, that is, substances which inhibit the absorption of other nutrients. For example, raw eggs (which are often consumed for “maximum nutrition”) contain a substance which hinders absorption of protein like trypsin and biotin.  The red skin of raw groundnuts contains a thyroxin inhibitor. Uncooked beans, peas, cabbage and radish also contain similar inhibitors. These unwanted substances are destroyed by light cooking.

Raw vegetables can pose another kind of health hazard. The vegetables available in our cities are often grown and transported in very unhygienic conditions. Eating them raw may give you your daily vitamins but also exposes you to the risk of fifth borne disease (typhoid, cholera, and diarrhea). Raw eggs carry the risk of salmonella infection. Cooking makes them safer to eat.

So, all too often, correctly cooked food may prove more beneficial than raw foods. But remember, “Correctly cooked” are the key words. Food that is cooked to death will be about as nutritious as your dishrag!

3. The Longer Your Excise Session, The Greater The Benefits

No, the greater the chance you will injure yourself! Fitness followers have long accepted the notion that if a little exercise is good, a lot must be lot better. It’s only in recent years that studies have increasingly documented the fact that over exercising can be bad for you. It can lead to sprains, strains and pain. All three of which should not be part of your fitness programme.

Studies have also documented the adverse effect that strenuous exercise appears to have immunity. Researcher, David Nieman of the Loma Linda University in California surveyed 2300 runners competing in Los Angeles Marathon. Slightly more than 40 percent reported at least one bout of cold or flu in the two months before the race. What’s more, those runners who trained more than 60 miles a week were twice as like to have fallen silk as those who trained less than 20 miles a week.

Follow-up studies in which the marathoners were put to a grueling pace, and their blood tests then taken, showed a 60 percent jump in cortisol, a hormone secreted in response to stress, which has been shown to suppress immunity. Also, a 30 percent drop in the activity of natural killer cells immune system watchdogs that help fight off viral infection.

Other studies have confirmed these effects. University of Nebraska Physiologist Gerald Tharp found that full bore exercise also seems to cut the flow of some protective anti-bodies, such as IgA – an antibody found in saliva.

It is moderate exercise, scientist are increasingly finding, that primes the body’s defenses: such exercises prompts the flow of the body’s “natural opiate”, beta endorphin, which in turn can arouse immune cells to action.

So don’t push yourself too hard – or your workout too far. It just isn’t necessary or good for you

4. Hysteria Means Throwing A Fit

Skin rashes, paralysis, blindness, deafness, pain in the part of the body, difficulty in swallowing and loss of memory – any of these may represent hysteria.

Mention the word ‘hysteria’ and most people conjure up visions of a woman wildly trashing her arms about, laughing and crying at the same time and screaming like a banshee, her hair all awry. In actuality, hysteria is a mental or psychological disorder which ‘converts’ into a physical symptom. Society is more prone to sympathize disturbance; so, hysteria is really a cry for help and attention.

Apart from typical hysterical fit that most people may have seen, there are several other ways in which hysteria may manifest itself. Conversion hysteria takes the form of loss of function of some body part:

  • The patient may ‘become’ deaf, mute or blind. The blindness could be in one eye or both.
  • He may ‘develop’ paralysis or rigidity of any part of the face or body.
  • He may complain of pain in any area of the body or noting else.
  • He may develop skin rashes on accessible parts of the body – like the arms and neck, because of continuous nervous scratching.
  • He may develop tics over the face.

Many of these symptoms are dramatic, but totally reversible. Recovery is just as sudden as the onset of the disability.

The most interesting of all hysteria symptoms is loss of memory, which is quite real. An unbearable situation of stress can make a person wander about far from home, having forgotten who he/she is: this is known as ‘hysterical fugue’. There are recorded instances of wives reacting to their spouse’s infidelity in this way wandering away from home and even adopting the names of the husband’s mistress during amnesic state!

5. You Can Only Get Tetanus From A Rusty Nail, Blade Or Other Metallic Object.

Rusted objects are highly potent source of tetanus infection, but by no means the only one. The tetanus bacteria (clostridium tetani) are mainly found in cattle and horse manure, and also, to a less extent, in the faeces of other animals, even in human faeces. Their spores (reproductive cells) may survive in the earth, undisturbed for long periods. From there they spread to any number of objects, including clothing, pieces of wood, rocks, house dust or, for that matter, nail or blades. But the spores require an oxygen deficient environment to thrive, and that is what makes rusted objects a major risk – the oxygen around the object has been used up form ferrous oxides, i.e rust.

But tetanus can also be got if an open wound is directory infected with horse or cattle manure, and that is way it occurs more commonly in Indian villages where barefoot walking is the mode rather than the exception. The chances of infection increase if a wound has been tightly bandaged, especially if it has not been properly cleaned. In this case, the oxygen poor environment created by tight bandage enables the rapid multiplication of tetanus spores that may have entered the wound through foreign particles like wood splinters, gravel or manure.

Tetanus infection has also been known to occur as a result of surgery where improperly sterilized equipment has been used. New born run a similar risk if the umbilical cord is served with the rusty blade, knife or similar object, but today, tetanus toxoid immunization given to the mother during pregnancy confers immunity on her baby during child birth and for a short period thereafter. Later, the triple vaccine (DPT) and its booster doses provide the child with protection tetanus (also, against diphtheria and pertussis i.e whooping cough). Tetanus booster doses must be repeated every 10 years.

In case you suffer wound and have note been vaccinated against tetanus, an anti tetanus shot will provide one time protection.

6. Coconut Oil Nourishes Hair And Promotes Its Growth

There are two ways you can use coconut oil on your hair. You can apply it to the strands and/or you can apply it to the scalp. Oil (or any other application) that is used on the strands simple reason that you can’t nourish something that’s dead. And hair is dead from the point it pushes through cell that hardness as it emerges trough the follicle)

As for oil that’s applied to the scalp, it doesn’t penetrate the scalp to reach the hair roots, which are the living part of hair, the roots get their nourishment from with in i.e from the blood supply, and the quality of that nourishment is a matter of how balanced your diet is. Coconut oil, even if it did penetrate the scalp, would hardly provide all the nutrients your hair needs (being made up mostly of fats).

Apart from the dietary sustenance that all hair needs, the basic characteristics of hair is its thickness, rate of growth, texture and the maximum length to which it will grow are genetically determined. Whether it is silken – smooth/dry/greasy is a matter of how much sebum is produced by the sebaceous glands attached to each follicle. (This sebum is different in its composition from coconut oil, so oil cannot perform the same natural function). Genes are, of course, influenced in their evolution by geographical factors: the thick, luxuriant hair of those living in sunny is more reflection of this genetic evolution than of the coconut oil applications that are a flavored cosmetic practice there.

Does coconut oil do anything for the hair? Yes. By coating it, in much the same way that a conditioner coats hair it provides synthetic luster (a sheet that lingers even after the hair has been shampooed); it also makes hair more manageable.

As for coconut oil massagers, the benefits to the hair are likely to come more from the massage than from the oil. Massaging stimulates blood circulation to the scalp; the oil merely aids and ‘smoothens’ the act of lubrication.

7. Only Women Can Get Breast Cancer

Though it’s rare, men can develop breast cancer, and the tumor is similar to the type found in women. A painless lump near the nipple is most common, but the cancer can also surface as a sore on the skin or with hardened areas. Breast cancer typically strikes men 60 yeas of age or older.

A recent study in the United States concluded that while men comprise only 1 percent of all breast malignancies, the very obscurity of breast tumors in men cause’s problems. In fact, according to Drs Alan Leford and Patricia Numann of the State of University of New York Health Science Center of Syracuse, even many doctors don’t know a male breast tumor when they see one. And the men interviewed took an average 14 months from the time they detected lumps to the time when they sought diagnosis.

The study also revealed that most breast masses in men unlike in women are malignant.

But treatment of the cancer is unisex; modified radical or radical mastectomies.

8. Gelatin Strengthens The Nails

Gelatin’s only good for cleaning out the refrigerator, since quite a few kinds of leftovers can be mixed in with flavored gelatin to summon up a snack.

But the belief that gelatin can improve the condition of weak and brittle nails has persisted, possibly because gelatin (not the synthetic variety, but the one that’s made by boiling animal tissue) contains protein, which is also one of the main constituents of nails.

However, this is less than a remote possibility, not only because gelatin contains only very low-grade protein but, more importantly, because of the time a finger nail has grown out of the cuticle it’s already dead (much in the same way that hair is dead once it’s grown up out of the scalp), so no amount of protein will strengthen it from the outside.

What’s more, dermatologist says that, rather than protein, its sulphur and iron that determine the hardness of the nail. Different chemicals contribute to the healthy growth of a nail, so the best nutrients prescription would recommend a balanced diet with special attention to protein and minerals. Studies of nail growth have also shown that it can be slowed down by hormonal imbalance and even by psychological disturbance. Poor overall health is reflected in the nails.
