Emotion is a feeling about or reaction
to certain important events or thoughts. People enjoy feeling such pleasant
emotions as love, happiness, and contentment. They often try to avoid
feeling unpleasant emotions, such as loneliness, worry, and grief.
Individuals communicate most of their emotions by means of words, a
variety of sounds, facial expressions, and gestures. For example, anger causes
many people to frown, make a fist, and yell. People learn ways of showing
some of their emotions from members of their society, though heredity (遗传)may
determine some emotional behavior. Research has shown that different isolated
peoples show emotions by means of similar facial expressions.

Though everybody is different, most people need at least seven to eight hours of sleep per night in order to function at their best.
If you have been lacking energy, try going to bed earlier at night. If you can wake up feeling well-rested, it will be an indication that you are starting to get an appropriate amount of sleep at night.
