Getting in Rhythm to Enhance the Benefits of Sleep

Establishing a regular bed and wake time helps promote sleep by getting you in sync with your circadian clock so that you experience all of these sleep stages. Here are some additional practical tips for promoting quality sleep:



  • Avoid caffeine (coffee, tea, soft drinks, chocolate) and nicotine (cigarettes, tobacco products) close to bedtime.
  • Avoid alcohol as it can lead to disrupted sleep.
  • Exercise regularly, but complete your workout at least 3 hours before bedtime.
  • Establish a regular relaxing, not alerting, bedtime routine (e.g. taking a bath or relaxing in a hot tub).
  • Create a sleep-conducive environment that is dark, quiet and preferably cool and comfortable.


If you are having sleep problems or regular daytime sleepiness, it is helpful to use a sleep diary published by the National Sleep Foundation to record your sleep patterns and the amount of sleep you get. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can pinpoint any causes of poor sleep.
