Common causes of sleep problems include physical disturbances, psychiatric disorders, medical issues and environmental issues, notes WebMD. Medications, poor sleep habits, changes in work schedule and age may also cause sleep problems, according to Mayo Clinic.
Physical disturbances that cause sleep problems can include pain from various conditions, states WebMD. Psychiatric disorders that cause sleep problems include depression, anxiety, chronic stress and post traumatic stress disorder, explains Helpguide.org.
Asthma, hyperthyroidism, acid reflux and cancer are medical issues that cause sleeping problems, states HelpGuide.org. Environmental issues causing sleep problems could include the consumption of alcohol. Nicotine and caffeine are also stimulants that may interfere with sleep, reports Mayo Clinic.
Medications that may interrupt sleep include antidepressants, allergy medications, corticosteroids, and heart and blood pressure drugs, according to Mayo Clinic. Weight loss products and decongestants that contain caffeine may also lead to trouble sleeping.
Poor sleep habits are a common cause of sleep problems, reports Mayo Clinic. They can include an irregular sleep pattern, an uncomfortable sleep environment and stimulating activities before bed. Change in the environment or work schedule may also affect a person's sleep patterns. Working late and frequent travelling may interrupt a person's circadian rhythm and cause sleep problems.
Aging is another common cause of sleep problems, according to WebMD. Because older people tend to be less active and less restful, and because they frequently require more medications, they may have difficulty sleeping, explains Mayo Clinic.
