Set a Rhythm
Try to go to bed at the same time every evening. Set your alarm for approximately the same time every morning, even on weekends and holidays. This will help regulate your internal clock.
Take a walk, ride a bike or get involved in some other type of moderate exercise for 30 minutes every day. This will help you relax and release muscle tension. However, don't exercise in the evenings - the stimulation can cause you to be wide awake at bedtime.
A cup of coffee in the morning won't keep you up at night. But, avoid the caffeine in coffee, tea, chocolate or soda within six hours of bedtime.
Yet another reason not to smoke... nicotine is a stimulant and can make it difficult to fall asleep.
Check the Prescription Side Effects
Prescription and nonprescription medications often cause sleeplessness. Check with your doctor or pharmacist if you're on any medication.
It may be impossible to eliminate all the stress in your life. But reducing stress with relaxation techniques, visualization, exercise and other techniques can make a world of difference in the quality of your sleep.
