False. At the very least, wet hair alone is not a trigger for a cold. Only when cold viruses have settled in the mucous membranes of the nose and throat can wet hair promote the onset of a cold because it cools the body.
By the way, the same is true for cold feet. Blood flow to the nasal mucous membranes is reduced, so the mucous membranes dry out – an ideal place for cold viruses to settle.
12. vitamin C prevents colds.
False. At most, vitamin C can help you get through a cold better. However, several studies have found no evidence that taking more vitamin C strengthens the immune system.
13. if you want to burn fat, you have to exercise for 30 minutes
False. The body starts burning fat a few minutes after you start exercising. Even a casual endurance run is sufficient for fat to be burned.
However, it makes sense to do 30 to 45 minutes of endurance exercise three to four times a week for targeted fat burning. After all, fat burning continues for some time after exercise.
14.You should not drink water after stone fruit.
False. In the past, this warning may have been appropriate because drinking water has long not had the quality that we are accustomed to nowadays. As a result, bacteria got into the stomach, which together with the fruit caused fermentation processes, resulting in stomach complaints such as abdominal pain.
15.Swimming is good for the back
False. Only backstroke is good for the back and posture. When you swim breaststroke, the muscles on your spine tense up, especially when your head is above water. This is anything but healthy for the back muscles and can also overload the knee joints.
16. ice cold drinks refresh best
False. Cold drinks ensure that the body is deprived of energy. For example, when cold water is drunk, the body must heat it to body temperature before it reaches the esophagus. The energy expended heats the body more than the cold drink can cool it. That is why it is recommended to drink lukewarm beverages in summer.
17. wounds should heal in the air
False. Doctors have also long held this view, but it has now been recognized that air tends to dry out the wound. More scabbing can leave scars after the injury heals. It is better to apply a band-aid to the wound. Connective tissue cells can thus ensure a healing process without leaving a trace.
18. eating late at night makes you fat
False. Ultimately, it is the amount of calories consumed during the day that counts. If the energy balance was positive, more energy was taken in than consumed. In this case, fat would be put on. A negative energy balance, on the other hand, ensures fat loss.
Many people nevertheless eat nothing in the evening. The reason for this is digestive activity. The stomach rumbles and brings so many around the sleep.
19. cola helps against diarrhea
False. True, cola is good to provide the body with short-term fluids and minerals that it has lost due to diarrhea. But at the same time, the caffeine in cola stimulates the kidneys to dehydrate, increasing the lack of fluids. In addition, carbonic acid irritates the affected intestines.
20. do even more sports when your muscles are sore.
False. Sore muscles are the symptom of acute overuse. The pain with each movement is caused by tiny tears in the muscle tissue. These can even lead to local inflammation and swelling.
That is why you should wait with sports until the muscle soreness is over. Because then even the small muscle injuries are healed and sport is also much more fun without pain.
