1.  Create A Ritual
Every night before bed you should have a period of time away from electronics including computers, televisions and phones. This will become a ritual and that time each night will signal to your body that it is time to rest. During that period of time you can read a paperback book, take a nice bath or drink some herbal tea. These rituals help your body relax and unwind.

2.  Set The Mood
Getting amazing sleep is all about making your space relaxing and serene. Keep your space dark with little or no light. It increases melatonin and helps your brain shut down. There are great curtains available to help keep out the lights. The best temperature for sleeping is between 60 and 67 degrees Fahrenheit.

3.  Exercise During The Day
Get and stay active during the day. It helps decrease stress and increase positive chemical changes in the brain, like the release of serotonin. Make sure the exercise is at least a few hours before bed because that could have the opposite effect and keep you awake.

4.  Avoid Caffeine And Alcohol Before Bed
Caffeine is always a don’t before bedtime, but for many people caffeine should be stopped in the afternoon as it could keep you awake later in the night. Alcohol may seem like it helps you fall asleep faster, but it actually increases your chance of waking up in the middle of the night, which will lead to a less satisfying and restful sleep.

5.  Release Tension
Once in bed, take a few moments and do an overview of your body. If you are holding on to tension in certain areas, take a moment to relax those areas. This helps to calm the body and quiet the mind, which will help you get to sleep faster.
