SLEEP HYGIENE & BEHAVIOURAL MEASURES FOR INSOMNIA
KNOW YOUR SLEEP REQUIREMENT: Most adults function best with approximately 8 hours of sleep. Some need 10 hours a night and others need only 5. Your requirement for sleep is unique. What is right for your spouse or friends may not be what you need. If you need only 5 hours of sleep a night, do not worry about it, or try to force longer sleeping hours. Instead, learn to use your extra waking hours for something you would like to do or get done.
SLEEP AND AGE: The amount and quality of sleep varies in the course of each person’s life.
NOISE / LIGHT / BED SURFACE / ROOM TEMPERATURE:
HUNGER / FOOD: Hunger may disturb sleep. A light snack, especially warm milk, seems to help people get to sleep. Avoid late heavy meals. Heavy protein meal at night may worsen sleep.
CAFFEINE: Avoid coffee, tea, cola drinks and chocolate. Stop caffeine altogether if you have any type of insomnia. Some people are more sensitive to caffeine and may have insomnia even if they take a very small amount (such as a cup of tea or a piece of chocolate) during the previous morning. The usual half-life of caffeine in heathy adults is about 6 hours. The term half-life means the amount of time it takes for your body to eliminate half the amount of caffeine. For example, if you consume 200 mg of caffeine at noon you will still have 100 mg in your system at 6pm and 50 mg at midnight and 25 mg at 6am and so on. There are medical reports that show that half-life of caffeine may increase with oral contraceptives (to 12 hours) and antidepressant fluvoxamine (56 hours). It may increase during pregnancy (15 hours) and with liver disease. The half-life is 65-130 hours in newborns.
ALCOHOL: Alcohol can cause sleep apnea. It can fragment sleep especially during second part of the night. It alters your sleep stages. Although it may help to induce sleep, the chronic use of larger quantities of alcohol causes disturbed sleep and dependency.
EXERCISE: Regular exercise can be an effective aid to sleep. It also releases mental tension. It is better not to do heavy exercise within 6 hours of bedtime as that can cause insomnia by raising your body temperature.
IF HAVING TROUBLE FALLING AND STAYING ASLEEP:
INSOMNIA AS A SYMPTOM OF MEDICAL PROBLEMS: Sleeping problems may signal a medical condition such as anxiety, depression, and other disorders. It is important to get a proper diagnosis and treatment for the underlying cause of your sleep problems.
