Getting Enough Sleep

"A happy bedtime starts at dawn.  Sunlight sets your body clock, which determines when sleep hormones like melatonin trigger a nighttime drift toward dreamland."  prevention.com

So, get up at the same time every day regardless of what day it is or how much you have slept.  Then head outdoors to get some sun within 1 hour of waking up.  Also, avoid light-emitting devices like computers and phone for an hour before bed.  Most of us sleep best in temperatures between 60-67 degrees Fahrenheit.  I installed a number of nightlights for my loved one to prevent falls, but I have now removed some of them, so that I have a more darkened area in which to sleep.
