# Myth No 1. No less than 2 litres of water per day
This underlying premise of a healthy lifestyle was given to the public in the year 1945 for the first time. Collegium on nutrition in the USA advised all the prudent Americans to drink 8 glasses of water per day, in order to stay in shape and keep your body clean. Since then, many diets include the same recommendation, and rumour has it that a big number of liquid helps to lose weight.
In point of fact. In and of itself, the water will do no harm, but in large numbers, as known, anything can be harmful. Try to think of how much liquid you consume a day: even if to exclude all the other drinks, you still eat fruits and vegetables and receive moisture in doing so. If to push an envelope, hypernatremia happens as, or, simply put, lack of salts in a body. To increase massively the risk of cardiovascular and other serious diseases.
# Myth No 2. Hair goes grey from stress
In the latter days, stress causes everything from pimples прыщей to cancerous tumours. Such a green light, perhaps, goes second in popularity after «low on vitamins» and « unhealthy diet ». By the way, those cause hair loss oftentimes.
In point of fact. Stress has a negative impact on one`s body indeed. The more a human gets stressed, the fasters/he grows older because stress makes it to where the number of free radicals increases. And they, in their turn, are the chief culprit of wrinkles and hair loss. However, there is no scientific support that stress causes hair going grey. Our genes but not the ability to control oneself define the time of grey hair to show up.
# Myth No 3. Reading under dim lighting causes strain eyes
Do you remember what your mother told you when you were little? Clean teeth in the morning, wash hands before a meal, sit up straight and do not read under the blanket. Now a good half of the population on our planet is secure of this rule to be inviolable.
In point of fact. While reading under feeble lightening, your vision is to strain a lot. However, headache and wrinkles what you are to have in that case. Besides that, your eyes might hurt for some time afterwards. You are going to feel scratching and dryness but it will all go away soon. There is no long-term effect on reading at poor lightening.
# Myth No 4. Coffee is harmful
The arguments between coffee lovers keep on growing for many years and, perhaps, are not going to stop for quite some time.
In point of fact. Let us roll around a matter of common sense. Of course, if to be around a coffee machine all throughout the day, you are going to turn into a real bundle of nerves by the evening ready to explode any minute. However, if to be reasonable, coffee maybe even useful.
First of all, coffee, just like green tea, contains antioxidants (for example, if a question is about the natural product). For this reason, it decreases your risk to become type II diabetes. One of the recent studies made by Harvard University showed that women who drink coffee daily, this risk falls 30% down. Other similar studies show that coffee decreases the possibility of bowels cancer, liver cirrhosis, Parkinson’s disease and gallstone disease. One more advantage is that coffee stimulates brain activity and, contrary to common belief, does not increase chances to disrupt the cardiovascular system.
At that, 3 cups a day is a norm for everyday-joe (at the rate of 100 ml in a cup). If this amount brings you insomnia and evaluated pressure, downsize it twice or switch to substitutes. It is better to consult a doctor during pregnancy or calcium deficit.
# Myth No 5. Starve at high temperature
This myth goes from distant times when there was no medicine to cure a cold and people were ready to use the most absurd remedies in order to get cured. One more reason for such a belief is that gastrointestinal digestion increases the temperature of a body. People, who are into self-treatment, also believe that it is not worth the trouble to withdraw strength from a body for digestion. It has little strength after all.
In point of the act. As a rule, different viruses cause cold and high temperature, which live within for 10 days. Your food ration does not impact the life duration of a virus. Medical workers have no scientific evidence of a diet during a disease to influence body resistance somehow, however even if you do not really feel like eating, it is better to have some little but juicy snack. Because no matter which way you look at it, the liquid is simply necessary in order to avoid body dehydration. Besides that, moisture will help you to have an illness easier, it will reduce the number of mucus, hence softening cold in the head and cough.
# Myth No 6. Fresh produce is better than frozen
Since the time when scientists found out about such a wonderful thing as antioxidants, specialists on nutrition pray for fresh produce. Freezing kills the usefulness of a product. Same concerning cooking method connected with sanitization.
In point of fact. Frozen fruits and vegetables can be no worse than fresh ones if they were gathered and frozen at the height of ripeness. And cold-treatment along with sealed package save more vitamins that are remained in «fresh» products lied in the sun or a fridge of a supermarket.
# Myth No 7. Egg consuming increases cholesterol level
The logic of this statement is simple: there is a lot of cholesterol in eggs – accordingly, if to eat them, the level of this harmful substance in blood will increase.
In point of fact. The latest studies in this area showed that the level of cholesterol influences only certain types of edible fats. Moreover, there are less of them in eggs than, for example, in semi-fat milk (almost twice). At that, eggs contain proteins, vitamins A and D. They are cheap, available and easy to cook. Thus, one egg a day is going to be a very useful component in your diet.
# Myth No 8. If to freeze for a while, you will get cold
Yet another common knowledge told back in childhood times. Moreover, if that was what the mother said, it is so?
A point of fact. Surface temperature fall has nothing to do with immune status. If only it is not about the utmost freezing injury when getting cold is not something to worry about. We are getting cold, as has already been mentioned, above due to viruses, but not because of cold. Concerning a tendency in accordance to which the biggest number of cold-related diseases happen to be in cold months, it is not connected with a temperature. The thing is that in winter we spend more time in closed spaces, pushing on the subway, sit in cafes instead of walking down the streets. While this is the most fertile ground for infection to outspread.
