Mistake 1: raise your chin when you have nosebleed
The only advantage of this method is that it will not flow nose blood to the floor, but will not stop nose blood, instead, it will let nose blood flow into the throat, and may even cause vomiting and suffocation. The correct way is to put a small cotton ball in the nostril with nosebleed, press the nose wing gently, and lean the head forward, or put an ice towel or wet towel around the neck to stop bleeding.
Mistake 2: shave off the armpit hair to reduce sweating
Shaving armpit hair has no effect on preventing perspiration. On the contrary, after shaving armpit hair, armpit will leave perspiration on clothes because the water discharged cannot be hidden. Moreover, it is easy to cause hair root abscess by scraping armpit hair. The correct way is to wash the sweaty armpit before the sweat decomposes.
Error 3: sweat stinks
Sweat has no taste. But sweat contains a lot of organic substances, which are nutritious to bacteria, but when bacteria decompose sweat, they will produce smelly waste.
Error 4: brush your teeth immediately after meals
Brushing your teeth immediately after eating will make the acid in the food erode the enamel, which will only strengthen the damaging effect of the acid in the food on the teeth. The correct way is to rinse your mouth first and brush your teeth after half an hour.
Error 5: drugs work equally for men and women
The latest research shows that drugs have absolutely different effects on men and women. Aspirin, for example, can prevent myocardial infarction in men, but not in women. Oil soluble drugs like anesthetics are used in larger doses in women than in men.
Error 6: combing your hair 100 times a day is good for your health
Excessive combing will stimulate the sebaceous glands on the scalp, especially those with oily hair, and should be done less. If it's a long dry hair, it's more suitable to comb your hair. But it's better to use a comb made of natural mane, so it's not easy to hurt the scalp.
Error 7: it takes more energy to walk than to stand
Because, when standing, the legs are always bearing the weight of the body, and neither foot can relax. Walking is when one leg bears the weight, the other is relaxing.
Error 8: people with sweet blood are easily bitten by mosquitoes
Mosquitoes don't smell blood at all. But mosquitoes are particularly sensitive to heat, and even the difference of 0.05 degrees Celsius can be distinguished. Therefore, when we exhale carbon dioxide and water vapor, we will attract mosquitoes.
Error 9: toilets are very unsanitary places
Toilets that are often washed with water are much cleaner than people's stereotype. Family bacteria research experts found that most of the bacteria in the home are hidden in the drain pipe on the inner wall of the refrigerator, and there are more bacteria on the dishcloth than in the toilet.
Error 10: smart people have big heads
Brain size is not the key to intelligence. Brain structure is the most important. The function of human brain is determined by neural network, and people with low IQ are dead because some functions in this field have nothing to do with brain size.
