As mentioned earlier, the stress that stems from common life situations often contributes to sleep problems.
A relaxing activity around bedtime can help relieve tension and encourage sleep.
Consciously attempting to clarify problems and formulate solutions can have a positive effect on sleep quality. Talking with a trusted friend or colleague to "air out" troubling issues can be helpful.
Relaxation exercises, meditation, biofeedback, and hypnosis are sometimes beneficial in controlling sleep problems. These techniques should be learned from a psychologist, physician, or other healthcare professional.
