People who are easily bitten by mosquitoes will take vitamin B orally and excrete it from sweat after physiological metabolism, which will produce an odor that mosquitoes dare not approach. Take vitamin B 1 ~ 2 tablets orally 30 minutes before going to bed, but don't take them in large quantities for a long time. In addition, a few drops of vitamin B solution in the bath can also play a certain anti-mosquito role.

① Foods rich in vitamin B 1: wheat germ, pork leg, soybean, peanut, pork tenderloin, ham, black rice, chicken liver, germ rice, etc.

② Foods rich in vitamin B2: eel, beef liver, chicken liver, mushrooms, wheat germ, eggs, cheese, etc.

③ Foods containing vitamin B6, vitamin B 12, nicotinic acid, pantothenic acid and folic acid: liver, meat, milk, yeast, fish, beans, egg yolk, nuts, spinach, cheese, etc. Vitamin B 1 cannot be stored in human body, so it should be supplemented every day.

It is difficult to get all the B vitamins, but it is simple and convenient to get them through careful food selection. The above foods containing vitamin B can be divided into two groups: ① and ②. Looking at the above classification, we can see that ② and ⑧ are both contained in roughly the same food. Therefore, ① as a group of foods, ② and ③ are combined into a group of foods, and two groups of foods are selected in combination, so that the B vitamins can basically be held in your hand.

Mosquitoes suck human blood and are also "picky", looking for objects that meet their "tastes". When mosquitoes "buzz" around a sleeping person's pillow, they rely on proximity sensors to sense temperature, humidity and chemicals contained in sweat. Therefore, female mosquitoes first bite people with higher body temperature in love sweating. Because of the high body temperature, the odor secreted by people in love sweating contains more amino acids, lactic acid and ammonia compounds, which are easy to attract mosquitoes.
