Going to bed and getting up at roughly the same time, all the time, will programme your body to sleep better.
Your bedroom should be kept for rest and sleep and it should be neither too hot, nor too cold; and as quiet and dark as possible.
It's difficult to get deep, restful sleep on one that's too hard, too small or too old.
Regular, moderate exercise such as swimming or walking can help relieve the day's stresses and strains. Cut down on stimulants such as caffeine in tea or coffee - especially in the evening. They interfere with falling asleep and prevent deep sleep. Have a hot milky drink or herbal tea instead.
Too much food or alcohol, especially late at night, just before bedtime, can play havoc with sleep patterns. Alcohol may help you fall asleep initially, but will interrupt your sleep later on in the night.
Yes, it's bad for sleep too; smokers take longer to fall asleep, wake more often and often experience more sleep disruption. Try to relax before going to bed Have a warm bath, listen to some quiet music, do some yoga - all help to relax both the mind and body. Your doctor may be able to recommend a helpful relaxation tip too. If you can't sleep, don't lie there worrying about it. Get up and do something you find relaxing until you feel sleepy again - then go back to bed.
