STEP 1 Get plenty of sleep 多睡觉

Get plenty of sleep. Your body needs 7 to 8 1/2 hours a night. Many metabolic processes occur when you're sleeping.

There is nothing wrong with taking a nap if you need one.

STEP 2 Exercise 锻炼

Exercise when you can. Exercise is important for both your mental and physical health.

STEP 3 Don't stress 不要有太大压力

Don't stress out. Set aside a few minutes of quiet time each day, shutting out all distractions, to calm down and gain focus.

Learn to say "no." You don't have time for absolutely everything; some things just have to wait.

STEP 4 Brush your teeth 刷牙

Brush your teeth and gums. Your dental health has more to do with your overall health than you might think.

STEP 5 Be social 要有社交活动

Be social. Health is more than just your physical well-being. You need to have emotional needs met and that means maintaining family and friend relationships. Surround yourself with people who care about you for your whole happy, healthy life.
