Trouble getting to bed at night? You're not alone.
According to the National Sleep Foundation, more than 13% of American adults report problems sleeping. And there isn't much that's more important to your overall health than good sleep. Luckily, for many, a good night's rest is only a few short steps away. Cure your insomnia by redesigning your room for maximum tranquility.

Choose the Right Color
The color you paint your bedroom walls and the colors you use to decorate can affect the way you feel inside your room and, ultimately, can affect your sleep. Studies have shown that subdued shades of blue and green can elicit feelings of relaxation, calmness, comfort, peace, and hope. Other lighter colors such as peach and tan may also help calm your senses before bedtime.

Get the Right Bed
When you're spending almost a third of your lifetime in your bed, it makes sense to commit the time and money needed to make sure it meets your needs. When it comes to beds, there's no one-size-fits-all. Find a store that lets you test a mattress for 30 days before buying. Test out different mattresses and pillows to select the right size and firmness for you. If you're waking up stiff or sore, try a new mattress or pillows.

Turn Down the Light
It seems obvious, but making sure your room is dark enough is essential to a night of quality sleep. Turn off or block all light sources, and make sure that you have curtains or blinds on your windows; even street lights and moonlight can wake you up if you're a light sleeper. If you need some light to fall asleep, don't just use any old lamp; get a night light or dimmer switch-controlled lamp that will emit soft, gentle light

Turn the Clock
A simple but effective adjustment to your bedroom layout – turn your clock so that it faces away from your bed. First of all, if your clock glows, the low light it emits could affect your sleep. Second, watching time slowly tick by as you lie in bed will cause mental stress that keeps you from ever falling asleep.

Get Rid of the TV And the computer.
Your bedroom should be a place of sleep and intimacy, and your electronics can affect both of those. Move your TV out into the living room. If you use your bedroom as a home office, make sure that when you put away your computer, you can put it out of sight. While you're at it, make sure there's no soft blue glow coming from your cell phone or iPod either.

De-clutter
Organize your closet and shelves so that there aren't piles of clothes and stacks of books lying around your room. Move unfinished projects out of your bedroom so they don't stress you out when you're getting ready for bed. An uncluttered room will lead to an uncluttered mind, less distraction, and easier relaxation.

Clean the Air
Breathing easier will lead to sleeping better. Open the windows regularly to air out your bedroom and get fresh air in and stale air out. Try putting an air-purifying plant or a HEPA-filter air-purifying system in your bedroom to rid the air of toxins and allergens. Finally, consider aromatherapy; mist your pillow with water infused with lavender, vanilla, sandalwood, bergamot, or chamomile to soothe your senses before bedtime.

Still Can't Sleep?
If you've redesigned your bedroom but still lie awake at all hours of the night, it may be time to take further steps. There are some small behavioral changes you can make during the day that pay huge dividends at night. And if those don't work, consider this comprehensive list of insomnia treatments. No matter what, don't accept a life without sleep; you deserve better!

Thanks a lot for the really helpful tips, what about mattresses, how to choose one?

The range of mattresses is really huge nowadays, it might become a real problem to chose a suitable one, moreover, the prices on good items are never low. Last time I needed a new one I relied on this review https://sleepissimple.co.uk/ , happily it is detailed enough and comprehensive. So that I choose one of memory foam mattresses, Eve Foam Rolled Mattress to be more precise (it can boast with three high-density foam layers and plush fabric cover, medium firmness (6-7) and 10-years warranty). Before choosing a good mattress you need to pay attention to the next factors: price, support, comfort. Don't forget about these features: cover, layers, firmness, motion transfer, ability to provoke allergy. Good luck, I am sure you will make right decision.
