Did you know that scientists have figured out the best conditions for sleep?. Even they understand how precious it is to us. You might be just a few lifestyle tweaks away from getting perfectly solid shut-eye.

Here are a few things that can contribute to a great night’s rest:

TemperatureResearch has found out that cooler bedrooms make for the best sleep. Your body temperature goes through a pattern throughout the day, dipping as your approach bedtime and continuously cooling until morning. Sleeping in a warmer setting can disrupt your body temperature cycle, making you restless.

LightWhether your eyes are open or not, light signals the brain that it’s time to be awake. Low light triggers your brain to produce melatonin, the sleep-inducing hormone.

ComfortThis one should really speak for itself. The best sleep when is you feel the most comfortable.

Clean your room In some cases, getting the best sleep can be as simple as cleaning your room. Unorganized clutter around the room can cause subconscious anxiety resulting in an unknown restless feeling.

White noiseEven though you’re asleep, whether you realize it or not, your brain continue to register sound. Ideally, the sounds you fall asleep to should stay with you until you wake up in the morning. And that’s where white noise comes in. Studies have found that a constant ambient sound greatly helps people sleep through the night.
