After being awake for nineteen hours, people who were sleep-deprived were as cognitively impaired as those who were legally drunk… After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours.
The thalamus acts as a relay for information from the senses to the cerebral cortex (the covering of the brain that interprets and processes information from short- to long-term memory). During most stages of sleep, the thalamus becomes quiet, letting you tune out the external world. But during REM sleep, the thalamus is active, sending the cortex images, sounds, and other sensations that fill our dreams.

Use white noise to fall asleep in noisy environments. White noise is a constant, unobtrusive noise that helps you ignore disturbing sounds, like noisy neighbors or a busy street. It can be the sound of static, raindrops, rustling leaves, or calm, wordless music. You can look for a white noise channel on your video or audio streaming service, or invest in a white noise machine.
We know we told you to put away your phone before bed but, for this, we’ll make an exception. Try to drown out the noise of your fighting neighbours and their barking dog with an app like Sleep Genius ($6 on iTunes). Its underlying technology has been tested and used by NASA to help astronauts fall asleep. We say: If it’s good enough for the space program, it’s good enough for us.
Invest in really comfy bedding. This is just common sense — if it feels really good to climb in bed at night, you’ll look forward to it. A quality mattress that suits your sleeping style, along with supportive pillows and soft, breathable bed linens, can mean the difference between tossing and turning and drifting off as soon as your head hits the pillow.
