Whether you realize it or not, mental health plays a big role in your overall well-being. When you're mentally healthy, you are able to enjoy your life and the people in it, feel good about yourself, keep up good relationships and deal with stress.

Your health heavily depends on how rested you are. Sleep plays a role in your moods, ability to learn and make memories, organ health, immune system, and other bodily functions like appetite, metabolism, and hormone release. It also helps the body re-energize its cells and clear out toxins.

Quality of sleep matters, not just how many hours you get.

Good quality sleep means:

• Being asleep for 85 percent of the time you're in bed or more
• Falling asleep in under 30 minutes
• Waking up no more than once per night for no longer than 20 minutes
