Tip for good night's sleep.

If you have difficulty in sleeping at night, here is some good advice for you to have a good sleep.

1.   Avoid caffeine four to six hours before bedtime. Caffeine is in coffee, soda, iced tea, chocolate, and various medications.

2.   Research has shown that a heavy meal too close to bedtime interferes with sleep, but a light snack may help you feel sleep. For example, milk proved to help good nighttime.

3.   Try to get some exercise. Some studies have shown that exercise right before bed is not as bad as everyone might think.
