If you've ever slept on a truly comfortable bed you understand that not all sleep is created equal. As you sleep, your body cycles through five stages of brain activity. Each stage offers different neurological and physiological benefits. The stage of rapid eye movement, commonly referred to as REM. During REM your circulation and brain wave activity increase. The combination of neural stimulation and circulation allows your brain to solidify learning and memories, explains the Division of Sleep Medicine at Harvard Medical School. There are factors that reduce, delay or may even eliminate REM cycles leaving you more tired in the morning than you were when you went to bed the night before. Sleeping on a memory foam mattress can help increase the length of your REM by improving the quality of your sleep environment.

Temperature Regulation

Sleeping in a hot room might be annoying, but being too cold while you sleep actually prevents your body from entering REM.

• REM means your body is comfortable and relaxed enough to begin restoration.
• If you sleep on a mattress that doesn't retain heat well or in a cold room can cause you to shiver which reduces your circulation.
• Never feeling comfortably warm in your bed means never experiencing REM.
• A night with insufficient REM is a recipe for fatigue and exhaustion the next day.

Memory foam is viscoelastic, which makes it sensitive to both heat and weight-density. Traditional spring box and coil spring mattresses don't have the open, breathable cells like memory foam mattresses do which absorbs and redistributes body heat throughout the mattress which won't cause you to overheat.

• A memory foam bed, such as a Tempur Pedic mattress, warms your body more quickly by redistributing and retaining your body heat throughout the night.
• The quicker you get warm and comfortable the quicker you'll fall asleep and enter REM.
• Promptly starting your REM cycle means increasing the length of your restorative sleep.

Movement Resistant

Your body enters REM 70 to 90 minutes after you fall asleep. But falling asleep is nearly impossible with your partner flopping and twisting on the other side of the bed. Anything that delays falling asleep means your REM cycle is delayed as well.

• The layers of connected springs and coils in a box-spring mattress actually transfer movement between different areas of the bed.
• Individual cells in a memory foam mattress prevent you from experiencing your partner's every toss and turn.
• Lying on a Tempur Pedic mattress lets you be still without experiencing any external disturbances.
• By having fewer interruptions to your sleep helps to extend the REM cycle to its fullest potential.

When you find the best mattress for you, you will never miss out on the best night's sleep you could ever have.
