With the improvement of living standards, more and more people began to pay attention to the way of health preservation, and some people gradually summed it up. The four cornerstones of health preservation are: reasonable diet, proper exercise, less smoking and drinking, and maintaining mental health. Although many people know how to pronounce these four concepts, many friends say they are not very clear about what they mean.

What is a reasonable diet?

A reasonable diet doesn't mean that you can eat and drink enough. The so-called reasonable diet, first of all, means that everyone should have three meals a day on time, followed by what to eat. While ensuring nutrition, we should also pay attention to balanced collocation. It can't be said that every meal is meat, nor can it be all vegetables. It should be mixed, and there should be no bad habit of overeating.

What is proper exercise?

Nowadays, many people are office elites, and their job nature is to face the computer. Some even sit for a day, and after a long time, the body slowly changes from health to sub-health. Strangely, in the long run, they won't get sick. So no matter how busy you are, after working for a period of time, you must make sure that it is good to exercise, even if it is just a stroll for half an hour. Health is the capital of revolution.

What is smoking less and drinking less?

Many people know this, but it is not easy to do it, especially some male friends. Many smokers say that a cigarette after a meal is better than a fairy, but in fact it is their lungs that suffer from the smoke again. Smoking and drinking will not only affect your health, but also cause unnecessary troubles and delay things even if you are drunk.

What is maintaining mental health?

It is to have a good attitude, live happily every day and put aside all troubles.
