Cultural issues also affect the program. For instance, Christians do not want their babies breastfed by Muslims. Limiting activities in bed may condition the mind to react in a certain way every time one hits the sack. Going to bed at the same time at night and waking up at the same time in the morning also develops an internal clock which assists a person in getting restful sleep. Insomnia is the inability to sleep or even sleep satisfactorily.
Older persons are more prone to experience insomnia.
People who worry about not having a good night sleep often get insomnia. Excessive caffeine, smoking before bedtime, excessive napping in the afternoon or evening, irregular or continually disrupted sleep or wake schedules also cause insomnia. Dr. Ivanhoe Escartin of the DOH-NMP explained that insomnia may be transient or short term, lasting from a single night to a few weeks. Transient or intermittent insomnia occurs in people who are temporarily experiencing stress, environmental noise, extreme temperatures, jet lag or medication side effects. Escartin further explained that chronic or constant insomnia is the result of mental or physical disorders and depression.
