Five myths about a healthy lifestyle

Running for me has always been a punishment. No, that's it to do jogging. As a child he enjoyed playing football, then for a long time and seriously enough he played basketball. But run! It was always a pain to get up early, I regard it as a kind of tempering and pouring cold water (as well as a cold shower after a sauna), I regard as mockery of a person. I ate always how it would turn out, the good of the hostel and the army were tempered. The work process is tightly seated and in front of the computer, accordingly walks in the fresh air did not take root.

Here on this as a balm for the soul I read here are supposedly myths about the measures and methods advised for a healthy lifestyle :-)

It is worth of course to treat them wary, but it seems that there is something here ...

Myth 1. Running in the morning is always useful

Two years ago, scientists from the Institute for the Study of the Cardiovascular System at the Lehigh Valley Health Network (US, Pennsylvania) made an official statement that even with moderate enough loads, jogging can cause serious damage to health. This was preceded by a study involving 3,800 people engaged in running of varying degrees of intensity. Of men and women older than 35, a group with an average age of 46 years was formed and received an unexpected result.

The lifespan of those who run a lot and intensively, as well as those who do not engage in physical education at all, was less than those who run a moderately running. In this case, factors that could distort the clinical picture (chronic hypertension or hypotension, high cholesterol in the blood and smoking), were taken into account beforehand - none of them could affect the study. The deterioration in life expectancy statistics began at about 20 miles (32 km) per week, that is, only about 4.5 km per day. The latter corresponds to approximately 30-45 minutes of daily jogging - longer runs have led to a reduction in the average lifespan of runners. Especially expensive morning jogging was made for those who ran around the city in the vicinity of active traffic on the usual sidewalk, without special springs.



Myth 2. Low-fat food is part of a healthy diet

Have you heard that fatty foods supposedly contribute to the development of cardiovascular diseases, and fat-free reduces risks? Six years ago, the American Journal of Clinical Nutrition devoted a whole special issue to this issue. The editors combined 21 studies. We are talking about completely different clinical experiments conducted by unrelated hospitals and institutions from different parts of the United States. Participated in them almost 350 thousand "experimental", of which 11 thousand at the time of the beginning of the study have already been observed in cardiologists with symptoms of cardiovascular diseases.

The average duration of the study was 14 years. And the conclusion was: there is no direct connection between the consumption of fatty foods and the development of vascular and heart diseases. And if you avoid edible fats not out of fear of problems with cardiology, but from what you want to lose weight - classic fat-free products for you are completely contraindicated. Especially yoghurts, because in order to compensate for changes in taste due to reduced fat content, more sugar is added to these foods. So for a figure they are much more dangerous than ordinary fat ones.



Myth 3. Early recovery is a sign of a healthy lifestyle

The old English proverb, the analogue of the Slavic "Who gets up early ...", linking the early ascent with health, wealth and wisdom ("Early to bed and early to the rise makes a man healthy, wealthy and wise") - lies! Last year a group of researchers from the University of Westminster (UK) published a report according to which an early awakening leads to chronic stress. The fact is that approximately from 6 to 8 am the body produces the maximum level of cortisol - a stress hormone. But the most important thing is that awakening during this period keeps the level of cortisol overestimated throughout the day.

Accordingly, if early upsurge for you is a way of life, then the overdose of cortisol is a lasting phenomenon. Over time, it will have to pay for a decrease in immunity, chronic migraines and depression. At the same time, the utility of the morning exercise does not compensate for the harm of morning lack of sleep. So if you need to get to work or classes by 8-9 in the morning, it's better to postpone the physical exercises for the evening. By the way, the period most valuable for the body of sleep is considered to be the time from 8 pm to midnight and from 2 pm to sunset.



Myth 4. Desserts are evil!The astonishing conclusion of a group of scientists from Tel Aviv University, published this winter, contradicts all the traditional ideas about proper nutrition. If we want to lose weight, the first thing that we are recommended to refuse is confectionery products (a classic combination of animal fats and carbohydrates). This recommendation is refuted by the Israeli dietician Daniela Yakubovich and several of her like-minded people who have recently put on an amusing experiment. 193 people who wanted to lose weight, divided into two groups. The first was constantly fed with low-calorie food - 300 kilocalories per reception. The second group in the mornings was given a full breakfast - 600 kcal (eggs, meat, beans, vegetables), and then treated with dessert, but the total number of kilocalories per day was the same as the first group (1600 per day for men and 1400 for Women).

So, the weight loss rate for the participants in both groups was the same. But the indicator of stability of the achieved result in the second group was much higher: after 32 weeks the participants of the experiment, sitting on a strict low-calorie diet, began to recruit newly dropped kilograms, and those who ate cakes in the mornings were still losing weight. So, if you like to sometimes pamper yourself with sweet, henceforth you can do it with an easy heart. But only in the morning and knowing the sense of proportion: for those who eat confectionery kilograms, the most likely to become a diabetes type 2 diabetes and obesity.



Myth 5. Long walks in the open air are good for everyone

But not in the case if you have extra weight and if you are a city dweller. Scientists of the Department of Social Medicine at the University of Montreal studied the differences in the work of the respiratory organs of slender and fat people. It turned out that the depth of breathing correlates with the weight. The experiment showed that people suffering from obesity breathe an average of 50% more atmospheric air. The less excess weight - the less excessive breathing, but even with a minimum excess of its ideal weight, a person breathes 7% more air. At the same time, in the city together with him, he gets his share of gaseous pollutants - ammonia, sulfur dioxide, nitrogen oxides, etc.

If the rate of excess breath is higher than 10%, the result of regular long walks in the city is likely to be poisoning, which will subsequently be written off for general environmental contamination. In general, most people have enough common sense to beware when someone next smokes a cigarette, a strong smell of smoke reminds them of pollution. But we must remember that serious pollution is often present even where the smell is not felt.
