What are your best tips for hacking and optimizing your sleep, ladies? We’ve talked about different types of insomnia and using sleep cycles wisely, with lots of advice on sleep detractors like anxiety loops as well as some sleep tools like weighted blankets — but I don’t think we’ve ever had a general discussion on how to hack and optimize your sleep. (Oh, and we’ve got a TON of sleep advice for working moms — for both the sleep-deprived kids and sleep-deprived parents — over at CorporetteMoms.)
The Big Fish: The Big Things That Help You Optimize Your Sleep
“Good sleep hygiene” is the best way to get reliably good sleep, and that is all about having habits. Going to bed at the same time. Getting up at the same time. Keeping your bedroom dark enough to shut out street lights or other sources of light. Not drinking caffeine after 4PM. Not using devices or screentime right before bedtime.
(I have my iPhone set so pushing the Home button 3x gives my screen a red cast, which I read about somewhere as a good halfway point if you’re the kind of person who needs to check your phone right before bed. (Here’s our last discussion on how to deal with a boss who emails you at all hours.)
Now, if you have sleep problems you might want to add other things to your routine — for example, if you can’t fall asleep you may want to try a weighted blanket, melatonin, or listening to Gentle Whispering Maria (so many readers gave her a shoutout in our post on insomnia!). If your problem is wake up in the middle of the night you may want to try a spoonful of peanut butter before bed.
If you wish you could sleep “longer” in the mornings, try drinking tart cherry juice. (For my $.02, my biggest (controllable) problem right now is discipline in turning off devices and going to bed at a reliable time, but in the past I’ve suffered from that horrible 3 AM-wake-and-be-anxious form of insomnia.
Of course, my youngest sleeps horribly and often comes to bed with us; his preferred sleeping position is on my head — so that sometimes negatively affects my sleep.)
The Little Fish – Smaller Things that May Affect Your Sleep
Like a lot of people, I use the app Sleep Cycle for my alarm (with a nice long iPhone cord) — the theory is that it listens to your breathing (not creepy at alllll), detects where you are in your REM cycles, and wakes you up at an optimal time (if possible — it doesn’t let you oversleep). One of the things that I like best about the app is the ability to set up your own “Sleep Notes” — essentially, a way for you to track certain things and see how they affect sleep.
If you haven’t tried some of the things we mentioned above (particularly to solve problems, like weighted blankets, peanut butter, or cherry juice) this a great way to get some data on how those things affect you. I mostly track smaller things that I suspect affect my sleep:
- taking vitamins B12 or D
- Working out with weights
- Eating late
- Eating too much salt
- Turning off WiFi on devices near my bed
- Taking a shower before bed
A few interesting notes from my own sleep hacking experiments:
- working out didn’t affect my sleep one way or another
- PMS, which always FEELS like it affects my sleep, did not actually seem to affect my sleep (1% more negative sleep when I reported I was having PMS). Still, I wish there were a way to sync my sleep tracking app with my period tracking app (I’m using Clue right now).
- Things that did have an impact over the past 6 months:
- Vitamin D boosted sleep performance by 5%
- B12 boosted sleep performance by 4% (although when I take B12 reliably I feel like the main benefit is that I get to have my brain for the last few hours of the day instead of staring at the wall/TV in sheer exhaustion)
- Turning off WiFi: I saw a random thing on FB about how plants had stilted growth if they were placed near a WiFi router (Snopes notes that this is totally unverified.) After some thought I realized that my general sleep habit of having 4 WiFi enabled devices on my bedside table (Chromebook, Kindle, iPad, and iPhone) probably wasn’t the best. I changed all of them to airplane mode (even for the Chromebook, the default setting was that it was searching for WiFi even if the book was closed!) and I actively turn off WiFi on my phone before bed (but not cell service) — and saw a 3% boost in sleep performance. Not a huge trend — but it might be worth thinking about if you, like me, have a crazy number of devices near your pillow.
- Eating “a lot of salt” – As I get older I start to get more wary of eating a lot of salt, so I was super surprised to see that this one is in the “positive” category — but over the past 6 months when I reported eating a lot of salt it showed a 7% improvement in sleep. (!)
Things that negatively affected sleep:
- eating late (7% worse sleep)
Surprisingly the trends don’t show any real difference between stressful days, days where I didn’t drink alcohol vs days where I DID drink, days where I worked out (usually meaning walking/running but occasionally aerobics) vs days where I lifted weights, etc.
I wouldn’t have suspected the weather would affect my sleep at all, but Sleep Cycle tracks the weather as a matter of course, so I can now say that I sleep 7% better during foggy nights.
How about you guys — what do you do to hack and optimize your sleep? What are your biggest challenges regarding sleep right now (or what challenges regarding sleep did you face) — and how are you trying to fix them? What are your biggest game changers as far as sleep goes?
