I notice as I get older that it seems harder and harder to get a good night's sleep. Why is that?

There are many possible reasons for sleep disturbance. Aging seems to be one big factor, but researchers don't know what causes changes in sleep patterns. It may be an outward sign of changes in brain function.

Sometimes, outside factors affect our sleep habits. A partner who snores, the need to go to the bathroom, and many kinds of medications can cause a disruption in sleep. Drinking alcohol before bedtime is a common cause of sleep disorder.

There are other medical problems that can cause sleep problems. Some are more serious than others. A medical doctor can help you look for a cause and the best treatment.
