The modern world has done a number on our sleep cycles. While surely there have always been sleep disorders, living in a high stress world filled with lights, gadgets, and on demand entertainment has turned many of us into sleepless zombies. About 10% of the American population has chronic insomnia, and between 45% and 55% of us experience it infrequently.

Clearly this is a widespread problem. Calling it an epidemic would be an apt description, since it’s so common and incredibly bad for us. Sleep is like food and water. If you don’t get enough of it, every function in your body will be hindered in one form or another. And that of course, can put you into an early grave.

Fortunately there are a few simple (though not always easy) things you can do to finally get a good night’s rest. If you don’t want to be among the sleep deprived masses, consider the following:

Tobacco, Alcohol, and Caffeine

Everyone knows that caffeine can keep you awake and shouldn’t be ingested before going to sleep. Tobacco is another stimulant that can keep you up, and not just because of its brief energizing effects. If you smoke once or twice every waking hour, then that’s what your addicted brain is used to. But when you try going to sleep, all of sudden you’re going several hours without smoking. This often leads to restlessness and waking up in the middle of the night.

And finally, alcohol is one of the worst substances you can ingest before bed. Initially it will help you fall asleep fast, but like tobacco it hurts the quality of that sleep. You’ll get less REM sleep, and it may cause you to wake up in the middle of the night.

Light and Dark

It’s common knowledge that a dark environment is ideal for a good night’s rest. Even the slightest speck of light can hinder melatonin production (even with your eyes closed too) and throw a wrench in the gears of your circadian rhythm. It could be the numbers on your alarm clock, the lights on your TV, or the street lamp outside your window. Anything can throw you off. That’s why it’s a good idea to buy a sleeping mask and/or blackout curtains for your bedroom. Most people don’t even realize how much these tiny lights are ruining their sleep until they try out these options.

What most people don’t know however, is that experiencing daylight is just as important for your sleep. Research has shown that seeing and feeling more sunlight throughout the day helps you sleep better at night. When you stay inside all day under artificial light, your body doesn’t really know when it’s day-time and night-time. Thus, it doesn’t know when to sleep.

Electronics

And while we’re on the subject of how light affects your sleep, you should avoid all contact with electronics for at least an hour before bedtime. As I said before, any form of light can hinder your sleep to some degree, but computers and cell phones are the worst. The light from these devices, as well as LEDs and fluorescent bulbs, is often tinted blue. That color actually induces wakefulness and focus, and it can hinder your sleep for several hours after you see it.

Skip the Snooze Button

The problem with hitting the snooze button on your alarm clock is that it interrupts your sleep cycles, which typically lasts about 90 minutes and consists of 5 stages throughout the night. Hitting the snooze button causes that cycle to restart unnecessarily as you drift back to sleep. You would feel more restful if you had just set your alarm clock a few minutes later. Not only that, but the snooze button has a tendency to disrupt your hormones and your circadian rhythm.

And when you think about it, you shouldn’t need an alarm clock either unless your work schedule changes from day-to-day. If you need an alarm clock to wake you up every single morning, then you’re not getting enough sleep. Set it every night anyway just in case something disrupts your sleep, but don’t rely on it. If you’re really getting plenty of consistent rest, and you’re disciplined enough to go to bed at the same time every night (which your body loves), you’ll wake up at the same time every morning a few minutes before that alarm clock goes off.

Exercise

One of the best remedies for occasional insomnia is a workout. If you sit on your butt all day, your body will have an abundance of energy that it wants to burn off, and that will keep you awake. If you really want to conk out fast, then you need to feel exhausted at the end of the day, and obviously exercise can do that. Even moderate exercise like walking and jogging can help take care of your restlessness. Keep in mind however, that this works best for the majority of the population that doesn’t have a sleep disorder. If you have chronic insomnia, then you should know that exercise may not have the same effect on you.

Find the Perfect Temperature

We all know that a hot muggy evening or a freezing cold night can make it difficult to sleep. However, the temperature range that provides the best sleep isn’t as broad as you might think. Anything between 65 and 70 degrees will put most people to sleep the fastest, and help them feel more restful when they wake up. To fall asleep, the temperature of the human body needs to decline slightly, and that aforementioned temperature range helps your body maintain that state. If the room temperature drifts too far from that range, then your body will have to work extra hard to maintain the lowered temperature, and you’ll struggle to sleep.
