A good rule of thumb is to avoid all caffeinated drinks including tea and certain sports drinks at least 10 hours before bedtime or if you sleep at night no caffeine after noontime.

Instead, try reading a book (not online), deep breathing exercises, or listening to relaxing music while dimming the lights.

Rule O: Not hitting the snooze button while you sleep.

Try not hitting the snooze button after the alarm goes off in the morning as the sleep you get during this time may be disruptive. Also, avoid the temptation of looking at the clock or cell phone to check the time during the night if you wake up as may be harder to fall back asleep.

If you are having difficulty with going to sleep or staying asleep on a regular basis important to discuss with your doctor as could be a sign of a more serious medical condition that may require treatment outside of the 5 Steps outlined above.
