All health improvements benefit from keeping a schedule. Whether that's working out everyday before work, stretching every night before bed or automating your meals, creating a schedule helps you to be prepared, and therefore, less susceptible to excuses, lapses and temptations.
Set a Sleep Schedule
Set a bedtime that works with your schedule, both during the week and on weekends, and stick to it.
4-6 hours before bed, do not eat or drink anything containing caffeine
2-3 hours before bed, do not eat a full meal
60 minutes before bed, turn off all electronics (unless you are a doctor on call, blackberries, cell phones and pagers should not enter the bedroom) and dim the lights. In the middle of your brain is something called the pineal gland. It releases melatonin, the hormone that readies the mind and body for sleep in response to lowered light levels.
30 minutes before bed, have something to drink. Water is preferable, but warm milk can help soothe you to sleep.
5 minutes before bed, make sure your bedroom is dark, quiet and slightly cool. The ideal sleeping temperature is 65°F.
Wake up at the same time every day, during the week and on weekends
Helpful hint: Reserve the bedroom for sleep and sex only. You are strengthening the association between your bed and sleep. Do not bring work into the bed, watch TV, talk on the telephone, or perform any other wakeful activities.
