Mayo Clinic Minute: Sleep spoilers - tips for a good night's rest

Dr. Virend Somers is a cardiologist who studies sleep.

Poor sleep may increase your rik of conditions such as heart disease, obesity, depression, dementia. And it even affects how you look. Dr. Somers offers the following tips: Avoid alcohol and big meals before bed; don’t exercise right before bed; and turn off all screens, including your smartphone, an hour before bed.

He also suggests keeping your bedroom as dark and quiet as possible. Healthy sleep for a healthy life.
