5.Menopause
As you stop having your period in middle age, your body slowly stops making the hormones progesterone and estrogen. This often causes hot flashes in which a surge of adrenaline wakes you up. This can happen many times a night. They can make you get too hot and sweat — sometimes a lot. Your doctor may be able to prescribe hormones to stop these flashes to help you sleep.
6.Sleep Rhythm Changes
As you get older, you tend to get sleepier earlier in the evening and wake up earlier in the morning. It can help to listen to your body as this shifts so that your sleep hours are more in tune with your body’s natural rhythms. You can ease yourself to bed with a soothing evening routine. Read a book or listen to calming music. A hot bath or shower and some light stretching exercises also can promote sleepiness.
