Provide yourself a good sleep

This seems so obvious, because if you did not sleep well the previous night, you are likely to feel tired the next day.
A good half of Americans have bad dreams at some periods of their life, and a strikingly large number of people 35 million complain of chronic insomnia. Scientists believe that sleep disorder is a common reaction to the changes taking place in our lives, from problems arising at work, to serious illnesses. For most of us, normal sleep is restored as soon as day problems are resolved, that is, when the source of anxiety disappears or things begin to go well.
If you start sleeping badly at some point, use simple advice provided by Patricia Prince, Ph.D., professor of psychiatry at the University of Washington Medical Faculty.
Try not to drink coffee, cola or other caffeinated drinks after 6 or 7 pm.
Go to bed at the same time.
Do regular physical exercises.
Do not drink alcohol after dinner. Alcohol has a bad effect on sleep.
