Help for the Sleep-Deprived (or Sleep Interrupted)

This posting isn't about food, but it's certainly on a topic that's very crucial to our health: sleeping well.
Some health-oriented folks, including doctors, believe that sleep may be the most important component in our entire health profile, above diet, exercise, vitamins, medications, and visiting doctors.
So here's some advice for those who have trouble staying asleep -- that is, you may fall asleep easily enough, but you wake in the night and can't get back.
It's from Real Age, and it's titled "Fall Back Asleep Fast with These 3 Tips"

1. Don't fight it. Tossing and turning works for salads, not sleep problems. If you can't get to sleep within 15 minutes, get out of bed and do some light activity, like a yoga pose or a short walk. Getting your mind off sleep resets and reboots your system. Then, once back in bed, invite sleep with some soft music or meditation. (Try setting the stage for sleep by doing this 7-minute evening stretch workout with Dr. Oz.)
   
   
2. Use the night. Dim your lights several hours before bed to avoid the stimulation caused by artificial-light pollution -- that stuff that emanates all around us thanks to TVs, computers, and indoor lighting. (And here's a great reason to nix midnight Web surfing, too.)
   
   
3. Treat your nose. Allergies can prevent and disrupt sleep, thanks to all the congestion they cause. Consider over-the-counter nasal strips or a nasal saline or antihistamine spray for a stuffy or runny nose. (Not sure if you have allergies? Read up on allergy testing.)
