We live in a world where good health is usually related to a certain kind of appearance. But it doesn’t mean it is necessary for good health. How can you tell if you are healthy? Here are some to look out for.

You eat when you’re hungry and stop when you’re full. This simple behavior is a symbol of healthy eating. “It sounds really silly, but many of us can’t do it,” said Geyer. Besides, you should eat a varied diet rich in whole foods. Natural food is much better than processed food. What’s more, eating enough is very important.

Experts suggest 150 minutes’ proper activities every week is good for our health, like quick walking. “Going quickly up two flights of stairs without stopping and feeling good suggests that your body can perform high intensity (高强度的) activity!”

You can face different kinds of emotions. Emotional health is as important as physical heat, and Geyer has a simple way of measuring (测量) it. “I think emotional well-being is facing various emotions and understanding that they’re all normal,” Geyer said. “And remember that no one of them is going to be permanent (长久的).”

You can wake up without an alarm clock. It is not surprising that no enough sleeping is terrible for your health. Lack of (缺乏) sleep increases the risk of illness. That’s why it’s important to sleep for eight hours a night.

You have the energy to do the things you want to do. Geyer said that there was one word that kept coming to her mind when she thought of good heath—energy. “Having the energy to do the things you want to do is usually a very good sign of good health,” she said.

Anyhow, remember that heath is individualized (因人而异的). If you’re worried you’re not healthy or you’re just curious about where you stand, you can go to see your doctor.

If you dropped a piece of fruit on your computer keyboard, would you think about eating it again? What if you dropped it in the toilet? Bacteria can live everywhere, even in some unexpected places.

If you eat in front of your computer, sneeze on your keyboard, or sit down to surf the Internet without first washing your hands, your keyboard will be bad for your health. According to the US National Research Center, the average computer carries 400 times more bacteria than a toilet bowl does.

Could one of the dirtiest things in your home be right in your hand? Yes, the TV remote control （遥控器）. It is dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that about half of the tested remote controls carry the cold virus.

Don’t forget your toothbrush. Do you put it in the bathroom? Studies show that flushing the toilet releases（释放）bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush.

At home

The kitchen is one of the places with the most bacteria more than the bathroom. Dishcloths（抹布）and kitchen sponges（海绵）are great places for bacteria since they are always wet after being used. Try to make them dry.

At school

When you put your schoolbag on the floor or on the bus, many bacteria can live on the bottom of it. Try to clean your schoolbag often.

In public places

Escalator handrails（电梯扶手）, shopping cart handles and public books and magazines are top bacteria carriers. That’s why the first thing to do when getting home is wash your hands.

Yes, bacteria are everywhere. But don’t be too afraid to touch those things. Most bacteria are harmless. Just remember to wash your hands regularly. It is the most useful way to protect yourself from bacteria and viruses.
