REM sleep occurs after the fourth stage of NREM sleep, with the first stage occurring about 90 minutes after you first fall asleep. The first period of REM lasts around ten minutes, and each stage lengthens until the final stage, which may last as long as an hour. Your brain activity is heightened during REM sleep, and you experience intense dreaming plus periods of muscle paralysis. As you age, you spend less time in REM sleep; adults spend about 20% of their sleep in REM, while infants spend about 50% of sleep in REM.

When we can't sleep, we become more focused on it. Panicked by our lack of shut-eye, we make constant changes to improve the situation - whether that's going to bed earlier, having longer lie-ins, or watching TV in bed. Consequently, we spend less time actually sleeping in the bedroom. The result? The connection between bed and sleep becomes weak, and we effectively un-learn how to sleep.

Adjust the thermostat. If you’re too hot or too cold at bedtime, sleep isn’t going to come easy. While there’s no ideal temperature for everyone, most people sleep comfortably when the bedroom is between 60 and 67 degrees. As you start to feel drowsy, your body temperature drops, which in turn helps you drift off to sleep. A cooler bedroom facilitates that. Don’t cool it off too much, though — shivering in bed isn’t conducive to a good night’s sleep.
