1. Cross your legs

For the first time about the dangers of crossing legs in 1999, the company declared the manufacturer of food additives. They even launched a large-scale advertising campaign The Great Cross-Out in the United States. And it was not a simple advertising ploy. Numerous studies confirm that the habit of sitting cross-legged (both on the chair and on the floor, in Turkish) leads to an increase in pressure (especially among hypertensive patients), varicose veins and nerve damage.

2. Feed the birds

Feed pigeons - one of the favorite activities of parents with children on a walk. Unfortunately, this is not only fun, but also dangerous. The probability that a city bird is sick with something infectious is over 50%. Pigeons suffer not only ornithosis, but also colibacillosis, histoplasmosis, salmonellosis, tuberculosis, listeriosis, tularemia, Newcastle disease, toxoplasmosis ... Are you sure you want to know the complete list?

3. Wear low-quality sunglasses

The desire to save makes manufacturers use cheap plastic. It does not protect the eyes from ultraviolet rays - in bright sun it can lead to a retina burn. Because of the blackout, the pupils dilate and receive a double dose of ultraviolet, which is even more harmful than walking without glasses at all. Overabundance of ultraviolet can cause cataracts, damage the eye and even lead to cancer.

4. Drink plenty of water

Yes, you did not misinterpret. Drinking a lot of water is not always good. However, to drink a little - too. Researchers insist that the body's need for water is very individual. If you move a lot and go in for sports - drink more, but if you have kidney problems or cardiovascular diseases, then the amount of fluid is better limit. In any case, the surest way to find out your norm is thirst. If you do not feel it, do not drink.

5. Healing with a Warmer

It seems to apply cold or hot to the sore spot - our favorite ways to relieve pain. But there is a whole list of diseases in which heaters are categorically contraindicated, so be careful. To warm a sore spot is impossible with bleeding, acute inflammatory processes of the abdominal cavity (appendicitis, cholecystitis, pancreatitis), in the first hours and within 1-2 days after injury and trauma. Also, thermal procedures are contraindicated in cancer diseases.

6. Cook popcorn in a microwave oven

And it's not in the way of cooking, but in the composition of corn, intended for home use. Danger is a chemical called diacetyl. This synthetic oil and flavor "in one bottle." Evaporating when heated, it enters the lungs and damages them. You can reduce the risk of getting harmful gases into the lungs, if you allow your air corn to cool before use.

7. Eat in the workplace

Of course, jobs are different. But more often than not they are not at all adapted for eating, but they also accumulate a huge number of bacteria that do not contribute to digestion. If this argument seems unconvincing to you, think also that the smell of your food can interfere with your colleagues, you yourself deprive the brain of a well-deserved rest, a leg-a useful workout, and the stomach does not allow you to digest food, since the brain can not concentrate on absorbing food until the end .

8. Wearing open shoes in the city

Of course, in summer you want to dress in all the most open, and shoes are no exception. But what do we risk? In open shoes there is a great chance to cut yourself, and in any country, whether it's an insect bite or a callus from an uncomfortable strap, an infection will easily fall into urban conditions. And it can hit not only the legs, but the entire body.

9. To drink low-fat milk

It seems that it is the same milk, just without fat. But in fact, this is not entirely true. Low-fat milk is not even close to useful alongside the usual. When fat is extracted from milk, vitamins also go with it, and synthetic substances come back, which are by no means useful. Many manufacturers "strengthen" skim milk, using powder, which can oxidize the cholesterol contained in milk. Although this has not been tested in humans, animals that have consumed oxidized cholesterol have found plaques in the arteries that can increase the risk of a heart attack.

10. Incorrect position of the body during sitting

Correct posture is the symmetrical arrangement of all organs. Take care of your back - adjust the office chair correctly and tilt the monitor. Here is the check list:

  • Select the height of the chair according to the length of the shin. Its seat must be firm.
  • Buttocks should occupy at least 2/3 of the chair.
  • The backrest should optimally match the curvature of the spine.
  • Lean back on the back of the chair so that the vertebral column is snug against it along the entire length.
  • Make sure that the shoulder blades are folded, the shoulders are at the same level, and the stomach is relaxed.
  • Do not put one foot on top of the other, as this will lead to blood flow in the lower extremities.
  • Do the movements smoothly so that the spinal column does not bump against the back of the chair.
  • Take such a position that the weight of the body was on the hips, and the head was pointed forward and up.
  • Do not rush to change the position, if it seems to you that it is uncomfortable to sit.

Let the muscles get used to the correct posture. Some of them will gradually relax, which will form the habitual posture, but this will not happen immediately.
