There’s been a lot of back-and-forth recently about how much sleep we really need, with recent studies suggesting that some long-held notions about this may be outdated. For example, a recently published study challenged the widely held belief that adults need an average of eight hours of sleep a night to function well. The researchers found that members of pre-industrial societies, free of the technological distractions that often keep us up at night, tend to get an average of 5.7 to 7.1 hours of sleep per night (more on that in a bit).
However, while the actual amount of sleep required to function optimally may vary from person to person, it is still very clear that not getting enough sleep — whatever that “magic number” is for any specific individual — can have serious consequences. This is especially true in children and adolescents, whose developing brains are very sensitive to insufficient sleep.
Studying the effects of sleep deprivation in teens
This was borne out in a new study published in this month’s issue of Sleep. Researchers from Singapore compared two groups of high school students before, during, and after a week in which half were allotted nine hours sleep per night and the other half only five hours per night. Not only did the sleep-deprived kids exhibit impaired cognitive function, alertness, and mood during their week of five-hour nights as compared with their peers, but it took them more than two nights of “recovery sleep” to catch back up again.
One way of looking at this is that not only do you suffer the day after not getting enough sleep, but that the idea of skimping on sleep during the week with the plan to somehow “catch up” on the weekend isn’t a good one: it simply doesn’t work. Even after getting lots of sleep on the weekend, you’ll still be far away from where you could — and probably should — be as far as sharpness and mood go.
Setting up a great night’s sleep for your child
One way of helping kids get the sleep they need is by eliminating some of those things that tempt them into staying awake. There is a lot of evidence that kids with televisions in their bedrooms, for example, not only sleep less but also have poorer-quality sleep. (Increased screen time is also associated with higher rates of obesity and with less time spent reading, but that’s a topic for another post.) The same is probably true for computers, tablets, and smartphones as well. Removing electronic media devices from the bedroom will make it more likely that your child will fall asleep sooner — and sleep better — than she will with the world at her fingertips.
Another way of helping kids fall asleep sooner and with greater ease is by removing stressors from their bedroom and encouraging them to relax before bedtime. This means, for example, not doing homework in the bedroom (and never in bed!), but at the dining room table instead. This creates a distinct boundary between the pressures of the day and the comforting space of the bedroom, which is so important for falling asleep. It may also have the added benefit of keeping them focused on the task at hand instead of the distractions of YouTube, Snapchat, and texting that can turn one hour of homework into a three-hour ordeal. Likewise, ending the day with 20-30 minutes of mindfulness practice, yoga, or quiet reading can help your teen redirect himself to a different plane as he gets ready to sleep.
Finally, keeping to a regular sleep schedule, seven days a week, with fixed wake-up and bed times will help keep your teen’s internal clock synchronized with the external one, preventing the development of a circadian phase delay between the two that may interfere with his or her being able to fall asleep at their appointed bed time on week nights.
Bible verses for today’s meditation and inspiration: Matthew E. McLaren
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 1 Corinthians 13:4-5
Let the morning bring me word of your unfailing love, for I have put my trust in you.
Show me the way I should go, for to you I entrust my life. Psalm 143:8
Let love and faithfulness never leave you; bind them around your neck, write them on the tablet of your heart. Then you will win favor and a good name in the sight of God and man. Proverbs 3:3-4
And over all these virtues put on love, which binds them all together in perfect unity.
And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in them. 1 John 4:16
