Want to sleep better?

I just received a call from a client who is having trouble sleeping.
It turns out she is not alone. Statistics show about 75% of adult Americans share her problem. We discussed how she typically spends the couple of hours preceding her bedtime. After some discussion I gave her these suggestions on how to get a good night's sleep.
As sleep patterns are determined by patterns of light and dark, imitate dusk by dimming the lights in your living room one to two hours before bedtime.
Do not drink coffee or depressants like alcohol, as they interfere with normal sleep patterns.
Exercise on a regular basis.
Avoid watching violent TV.
Make your bedroom as peaceful as possible in a quiet location away from your home office. If you have a computer in the bedroom, cover it up with a heavy drape.
Make sure the window coverings are heavy enough to block out light.
Block out the light from alarm clocks and night lights.
Keep your bedroom at a comfortable 68 degrees Fahrenheit.
Head to bed as soon as you start to feel drowsy.

My client scheduled a massage in her lunchtime so she could catch up on her sleep but realized she needs to adjust her habits.
