What bad habits can make people sick?

　　1.sleep Use pillows and mattresses

　　On average, each person sheds 1.5 million cells every hour. Even if he does nothing, he will sweat about 250 ml every day. Exfoliated cells accumulate on pillows and mattresses, which can easily lead to the breeding of mites. You may not feel it at ordinary times, but it is true that the weight of a mattress doubles every ten years, mainly due to the increase in weight caused by hair, sweat, animal dander, mold, spores, bacteria, chemicals, dust, mites, etc. After five years, 10% of your pillow's weight will be dust mites, which you inhale into your lungs while you sleep.

　　Treatment: Cover mattresses and pillows with airtight covers to block and prevent all kinds of dust from entering. In addition, change bed sheets and quilt covers frequently and wash them with hot water of about 60 degrees Celsius.

　　2. Keep the window open for a long time

　　When the weather is sunny, we like to open the windows and breathe in the fresh air. So some people like to keep the windows open for a long time, which may be a disadvantage healthy movement, seasonal allergens and air quality in many cities are of concern.

　　Treatment: Generally, opening the window for 30 minutes a day is enough. The window opening time is preferably from 9:00 to 11:00 in the morning or from 2:00 to 4:00 in the afternoon. Because during these two periods, the temperature has risen and the harmful gases deposited in the bottom layer of the atmosphere have dissipated, so opening windows is more effective for ventilation.
