13 Secrets to Better Sleep Doctors Want You to Know

You may not need eight hours

The latest research shows the right amount of sleep is what leaves you energized the next day. I’m a sleep doctor, and I’ve been a six-and-a-half-hour sleeper my entire adult life. These are the 10 things that happen to your body when you get too much sleep.

Ditch the pajamas

Sleeping in the buff lets your skin breathe and keeps your body cool, which makes it easier to fall asleep and sleep soundly. It also boosts intimacy. One study found couples who sleep naked are more likely to report being happy in their relationships.

Go ahead, watch TV

I’ve cured more insomnia than you can imagine by telling people it’s OK to fall asleep with the TV on. A lot of people simply can’t turn off their brains, but watching TV helps. Put it on a timer so it doesn’t disrupt your sleep later in the night. These are the 7 things highly successful people do before bed.

Everyone has sleeping quirks

Many people can’t sleep unless certain music is playing. Some adults always sleep with teddy bears. I even have one patient who has to shake a leg vigorously for 15 minutes while she falls asleep. I have no idea why, but it works for her. This is what your sleep position says about your personality.

A nightcap doesn't work

Alcohol may relax you so you nod off quicker, but studies show you’ll wake up more and get less of the REM sleep you need to feel rested.

There's an easy cure for snoring

Have a snoring bed partner? Hidden allergies are a big cause of snoring. Congestion narrows nasal passages, creating the vibrations that cause snoring. A decongestant or an antihistamine can help quiet it or it could be one of these 9 sleep apnea symptoms.

Yes, you can go to bed too early

One woman was worried because she woke up every day at 4 a.m. and couldn’t get back to sleep. But when I asked her what time she went to bed, she said 8 p.m. In certain cases, you don’t have insomnia; you’re just going to bed too early.

Write to stop worrying

To calm a racing mind, write down your worries and how you’ll address them tomorrow. Then try a mental exercise to occupy your brain, like counting up by sevens. Still can't get to sleep? These are the 11 habits that cause insomnia.

You might need therapy, not drugs

If you have insomnia, consider a referral to a clinical psychologist who specializes in sleep. He or she will use an effective technique, cognitive behavioral therapy, that gets to the root of the problem. Some studies show it works better than drugs.

No one is immune to caffeine

Even if you can easily nod off after a cup of joe, the caffeine keeps you in light stages of sleep. During sleep studies, we see a difference on your electrocardiogram (a recording of your heart’s electrical activity) from just one cup of coffee. Here's how to sleep better naturally without drugs.

Never sleep in this position

Sleeping on your stomach is the worst position for your neck and spine. The best? On your back with a pillow under your knees for support.

There are plenty of weird sleep disorders

Most people have no idea how many strange sleep disorders there are. People with REM sleep behavior disorder act out violent dreams. Those with sleep paralysis are awake but can’t move for a few seconds to a few minutes. Those with exploding head syndrome experience loud noises in their heads as they transition in and out of sleep. These 13 bizarre facts about dreams might keep you up at night.

Sleep can change someone's life

I once treated a State Bureau of Investigation agent who was taken out of the field because he fell asleep during stakeouts. He had severe sleep apnea, so I put him on a CPAP machine (which delivers constant air to the nose). Two weeks later, his wife hugged me and said, “Thank you for giving me my husband back.” As they walked out, she handed me a stack of papers and said, “I won’t need these anymore.” It was their divorce papers. That kind of story is why I’m a sleep doctor. These are the 7 sleep myths that are ruining your good night's rest.
