When it comes to sleep, we're doing it wrong.

Changes in our sleep patterns are a normal and common part of aging, but there are things you can do if you begin having trouble getting a good night's sleep. Although sleep problems can increase with age due to medical issues and changing circadian clocks, age alone does not cause sleep problems.

Poor sleep habits, untreated sleep disorders, medications, or medical problems can contribute to sleeplessness.

As such, gaining a clear understanding of how your body is changing and using tried and true ways to respond to those shifts can do a lot to help you get a better night's sleep. (Talking to your doctor is a great place to start.)
