Best-known health errors part 2

11. Wet hair causes a cold

Not correct. At least wet hair alone is not a trigger for a cold. Only when cold viruses have lodged in the mucous membranes of the nose and throat, wet hair can promote the onset of a cold, because they cool the body.

The same is true for cold feet. The circulation of the nasal mucous membranes is reduced, so that the mucous membranes dry out - an ideal place of settlement for common cold viruses.

12. Vitamin C prevents colds

Not correct. At most, vitamin C can help you survive a cold. However, several studies have found no evidence that the increased intake of vitamin C strengthens the immune system.

13. Who wants to burn fat, has to exercise for 30 minutes

Not correct. The body starts burning fat a few minutes after you start exercising. Even a loose endurance is sufficient to burn fat.

However, it makes sense for a targeted fat burning three to four times a week to drive 30 to 45 minutes of endurance sports. After all, the fat burning continues for some time after the exercise.

14. You should not drink water for stone fruit

Not correct. In the past, this warning may have been appropriate, because drinking water was far from having the quality we are used to today. As a result, bacteria have gotten into the stomach, which together with the fruit caused fermentation, so that there were stomach problems such as abdominal pain.

15. Swimming is good for the back

Not correct. Only backstroke is good for the back and posture. During breaststroke, the muscles on the spine cramp, especially when the head is above water. This is anything but healthy for the back muscles and can also overload the knee joints.

16. Ice cold drinks are best refreshing

Not correct. Cold drinks ensure that the body is deprived of energy. For example, when drinking cold water, the body must warm it up to body temperature before it reaches the esophagus. The energy expended heats the body more than the cold drink can cool. That is why it is recommended to drink lukewarm drinks in summer.

17. Wounds are supposed to heal in the air

Not correct. Doctors have also long held this view, but it has now been recognized that air tends to dry out the wound. The increased scabbing can leave scars after the injury heals. It is better to stick a plaster on the wound. Connective tissue cells can thus provide a traceless healing process.

18. Eating late at night makes you fat

Not correct. Ultimately, the amount of calories consumed a day counts. If the energy balance was positive, more energy was consumed than consumed. In this case fat would be applied. A negative energy balance, on the other hand, causes fat loss.

Many people still do not eat in the evening. The reason for this is the digestive activity. The stomach rumbles and gets so many to sleep.

19. Cola helps against diarrhea

Not correct. Although cola is good to provide the body in the short term liquids and minerals, which he has lost due to the diarrhea. At the same time, however, the caffeine of the cola stimulates the kidneys to drain and thus increases the lack of fluids. In addition, carbon dioxide irritates the attacked intestine.

20. Do even more sports for sore muscles

Not correct. Sore muscles are the symptom of an acute overload. The pain of every movement is caused by tiny cracks in the muscle tissue. These can even lead to local inflammation and swelling.

Therefore, you should wait with sport until the sore muscles are over. Because then even the small muscle injuries are healed and sports without pain also much more fun.
