Positive emotional states energize us. A sense of humor helps alleviate stress and ward off despair. Not too surprisingly, studies also suggest humor has a positive effect on our immune system. Humor allows us to look at the mishaps of life without becoming enmeshed in them. It is hard to feel sorry for ourselves and laugh at ourselves at the same time.
Laughter facilitates perspective and positive action.
We're not very likely to see our problems as insurmountable catastrophes if we're viewing them with some humor. Use of humor also makes it easier for others to be close to us and relax. Gently poking fun at ourselves, and not taking ourselves too seriously, is an effective medicine for many of life's ills. Fun and humor are part of what is meant by leading a full life or 'the good life'. As attractive as it might seem, lightening our approach to life isn't always quick and easy.
