Challenge yourself to stay awake – your mind will rebel! It’s called the sleep paradox, says psychotherapist Julie Hirst (worklifebalancecentre.org). She explains: “Keep your eyes wide open, repeat to yourself ‘I will not sleep’. The brain doesn’t process negatives well, so interprets this as an instruction to sleep and eye muscles tire quickly as sleep creeps up.”
Taking a nap might seem counter-intuitive to good nighttime sleep, but short naps of 10 to 30 minutes actually help you gain extra energy during the day and don’t disrupt your sleep. Even a 10-minute nap can improve your alertness for 2-and-a-half hours if you’re sleep-deprived, and you can feel the benefit for up to 4 hours if you are well-rested.
If you try just one sleep hack, make it this one. Junk light — the blue light that emits from your smartphone, laptop, and tablet screens — is wrecking your sleep. Too much blue light messes with your brain’s production of melatonin — the hormone that tells your body when it’s time to snooze. Blue light wakes you up and tells your brain that it’s daytime. Screens aren’t the only source of junk light — street lamps and LED lightbulbs are also to blame.
So soak up as much natural light as you can, even those last few minutes of blue light after the sun has gone down. And then avoid wandering around in bright artificial light as much as possible. And if you happen to get up in the middle of the night to go to the bathroom, whatever you do, don’t turn on those bright LED lights, because that will make it much harder to fall back asleep.
Your bedroom environment plays a big part in how well you fall and stay asleep. Too many people forget to optimize their sleep environment, and it has a real detrimental effect on their rest, says Cralle. Things to keep in mind: "How old is your mattress, what's the temperature like in your room, and is it really dark at night? We really need that darkness to get the melatonin going," Cralle says.
Everyone varies, and this is why you need to find out how much your brain needs. And you do that by keeping a sleep diary over a week or two, and just taking an average of how many hours you are actually sleeping. So not lying in bed, but subtracting the time it took you to fall asleep and any time you lay awake in the night. That’s the amount of sleep your brain got that night.
A lot of people don’t understand that these are two very, very different processes. A lot of people probably learned from basic psych in high school that you have these sleep stages: light sleep > deep sleep > light sleep > REM, and repeat. As you sleep more, you get less and less deep sleep, and also if you sleep-deprive yourself, you get more deep sleep.
