Better hygiene (卫生) habits can help you stay healthy

According to the World Health Organization, 60 percent of people's health problems are related(与…相关) to everyday hygiene habits. As the COVID-19 spreads across the world, governments and organizations in many countries have suggested that people should pay more attention to their daily hygiene practices.

In China, for example, people usually share dishes together at the dining table. But this habit has a high risk of spreading diseases through saliva(唾液). To fight against COVID-19, many cities in China, including Beijing, Shanghai and Guangzhou, have called on people to order separate(分开的)meals or use serving chopsticks(公筷) to take their food. Many people also suggest that Chinese should continue these habits after the outbreak.

In the US, the Centers for Disease Control and Prevention has asked people to develop healthy hygiene habits. For example, people should cover their mouth and nose with a tissue when they cough or sneeze.

    According to a survey by YouGov, a British market research company, many Americans have taken action to change their daily habits in the face of COVID-19.

Feet are an important part of you. Without them, you couldn't stand up, walk or run around. Your feet work so hard that sometimes they get sweaty (出汗).

Think of a hot summer day when you have been walking around all afternoon. Your feet have been in those trainers for a long time! The moment you take off your shoes, you feel good and relaxed, but your feet smell bad. You may think it is because of the sweat. But in fact, sweat itself has no smell. It's the bacteria (细菌) on your skin (皮肤) that mix with it and gives off a bad smell.

Bacteria love dark and wet places like the inside of sweaty shoes. The sweatier you get, the more bacteria there will be. When you wear your shoes, bacteria will have a good meal on your feet. They eat dead skin cells from your skin and then leave a kind of waste called organic acids (有机酸). These organic acids smell bad. Things will become better if you wear cotton socks.
