A good night's sleep is the foundation of good health. It restores both mind and body so you can wake up refreshed and ready to tackle your day. And when you can't sleep, it can set you up for a mental, physical, and emotional struggle all day long. Unfortunately, insomnia and sleep disturbances become more common as you age. The changes in brain patterns, medication, hormone levels, sleep patterns, and mood disorders like depression and anxiety that accompany the aging process can lead to chronic insomnia.
