Top Three Causes of Insomnia
Psychological, primarily stress. Don’t try to problem-solve at bedtime. Make a list and deal with it in the morning.
Lifestyle, an irregular sleep schedule can scramble your body’s sleep/wake cycle. Keep the same bedtime every night of the week. Don’t sleep in on weekends. Alcohol or caffeine in the afternoon or evening can disturb sleep, as can exercising too close to bedtime.
Medications, both over the counter and prescription. Decongestants, steroids, and medications for blood pressure, asthma, and depression can interfere with sleep.
