While you sleep, your body is hard at work. It restores hormonal balance, repairs itself, and keeps the circulatory and immune systems functioning properly. Your brain forms and stores memories.

Quality sleep allows you to be energetic and alert. It allows you to lose weight, exercise, work, learn, socialize, and do all the things you enjoy.

If you're not sleeping well, talk to your healthcare provider. You have a lot of options for getting better sleep.

That may include treating sleep disorders and/or improving your sleep habits. Your provider may also be able to suggest medications or supplements to improve your sleep.

But the most important thing is that you make sleep a priority. Set aside at least seven hours a night, and eight or nine if possible.

Maybe. Studies suggest it can improve your body image. It may also increase levels of the hormone oxytocin. But that's only if you have skin-to-skin contact with a partner. Oxytocin lowers stress and helps you form deeper emotional bonds. But if you aren't happy sleeping nude, it won't benefit you.

It's different for everyone. For many people, about 65 to 72 degrees F is ideal for sleep. Some may like temperatures as low as 60 degrees.

A warmer room can make it harder to fall asleep. It can also make you feel less well-rested.
