Sleep in a cool, dark room that is free from noises that may disturb your sleep. Sleep on a comfortable, supportive mattress and foundation. It's difficult to sleep on a bed that's too small, too soft, too hard, or too old. Cut down on stimulants. Consuming stimulants, such as caffeine, in the evening can make it more difficult to fall asleep.
Smokers take longer to fall asleep and wake up more often during the night.
Reduce alcohol intake. Drinking alcohol shortly before bedtime interrupts and fragments sleep.
