What are some healthy habits in life?

　　Easily mistaken in the world common sense , more than you know. we are many healthy Habits are wrong.

　　Mistake 1: Raise your chin when you have a nosebleed; the only advantage of this method is that it will not flow to the floor, but it will not stop the nosebleed. Instead, it will cause the nosebleed to flow into the throat, and may even cause vomiting and suffocation. The correct approach is to put a small cotton ball in the nostril of the nosebleed, gently press the nose, and tilt the head forward, or wrap an ice towel or a wet towel around the neck to stop the bleeding.

　　Mistake 2: Shaving armpit hair can reduce sweating; shaving armpit hair has no effect on preventing the production of sweat. On the contrary, after shaving armpit hair, sweat stains are left on clothes because the moisture discharged from the armpits cannot be hidden. Moreover, shaving armpit hair can also easily cause hair root abscesses. The correct approach is to wash your sweaty armpits before the sweat breaks down.

　　Mistake 3: Sweat smells; sweat has no smell. However, sweat contains a lot of organic substances, which are nutritious to bacteria. But when bacteria decompose sweat, they produce unpleasant excrement.

　　Mistake 4: Brush your teeth immediately after a meal; brushing your teeth immediately after eating will cause the acid in the food to erode the enamel, which will only intensify the damaging effect of the acid in the food on the teeth. The correct approach is to rinse your mouth first and then brush your teeth after half an hour.
