4. Sleeping In

Most people think they can "catch up" on sleep lost during the week. But when you get up late on weekends, it can actually be worse for you.

Your body has a natural wake/sleep cycle, also known as its circadian rhythm. When you stay up too late or sleep in too long, you upset that rhythm and make it tougher to get back on track.

Do this: Pick a bedtime and wake up time and stick with it. "The most important thing anyone can do is go to bed and wake up at the same time every day," Breus says. "Consistency is key."

5. Your Bedroom’s Temperature

When you are in a room that’s too hot or too cold, you may not sleep well, Breus says.

Do this: Of course, perfectly comfortable varies from person to person. Studies show that room temperatures below 65 and above 75 have an effect on sleep cycles. So try to keep it in that range.

You can always adjust the temperature to your liking, and hopefully, your partner will agree with that setting.

6. Your Mattress

A bad mattress and a pillow that doesn’t support your body right spell bad news for sleep.

Do this: Buy a new mattress every 8 years, or as needed. "Life changes, such as a car accident or back injury, can change your mattress needs," Breus says. "Also, if you move houses more than two or three times, the springs in a mattress can get damaged."

If you wake up stiff and sore every morning, then it’s time to shop for a mattress. Pillows are easy buys, so replace them anytime.
