February Is For Lovers (and sleeping)
I'm a little overdue for a new post. I got a bit of a cold at the end of January (good thing I was eating so cleanly or I think it would have been much worse than it was) and it gave me an excuse to be extra lazy for the last week. I'm pretty much better, so no more excuses. Or, as Fidel, the Cuban dishwasher I worked with years ago in a macrobiotic vegan restaurant used to say, "No eh-cuses! NO MAS!"
Now that my Whole30/Paleo challenge is up, I'm having challenge withdrawal. It went pretty well and I think it's time for a new challenge (maybe I'll just keep coming up with a new monthly challenge for the rest of my life. That could be interesting...) So, now that my diet is improved, the next thing that could use some improving are my sleep habits.
I think I was born night owl. As a kid, I never woke up at the crack of dawn like my younger brother did and I remember often playing in the dark in my room (or reading De. Seuss books by the light from the hall) when I was supposed to be sleeping. Can a night owl become a lark (or at least a robin?) Can we reprogram our sleep preferences? I sure hope so!
In the past I've had jobs that started at 7am and I lived in a perpetual state of sleep deprivation, since I could never discipline myself to be in bed on time (I wasn't a coffee drinker, so I can't believe I even managed!) I was in my early 20's then; my body would NEVER let me get away with that crap now! All those years of inadequate sleep didn't do me any favors and set me up for adrenal fatigue.
I've been thinking about attitudes toward sleep and it seems that in the U.S., we don't value sleep as much as we ought to. It's like an endurance contest attitude or something. I envy countries where night owls have a chance to make up for lost sleep during siesta time. That would probably be my ideal (maybe I need to relocate to España where they value their siestas and even have championships!) I probably wouldn't have had adrenal fatigue if I had been siesta-ing all those years;)
In my younger days, despite my lack of sleep, I had no sleep issues. Then, in my mid-late twenties, I developed insomnia, where I would wake up repeatedly throughout the night or just once but not be able to fall back asleep for hours. I tried a lot of things, but in the end, acupuncture and blackout shades were what worked (there was way too much light coming in through my windows, which really disrupts melatonin production).
In recent years, I've had intermittent issues falling asleep, largely due to bad habits like staying up too late and also computer usage at night (the blue light from computer screens also disrupts melatonin production and being online at night is also mentally stimulating. Bad combo.)
My recent sleep issues have also been of another variety: sleep wave cycle imbalances. I spend too much time in REM dreaming and not enough in slow wave sleep:
Slow Wave Sleep: The final stages of non-REM sleep, Slow Wave or Deep sleep, are marked by very low heart and respiratory rate, extremely slow brain waves and a complete lack of eye movement or muscle activity. Arousal from slow wave sleep is difficult and can result in disorientation and confusion. Slow wave sleep allows the body to direct its resources to regenerate tissues, build bones and muscle, recharge energy stores and strengthen the immune system.
Although REM sleep is vital to healthy brain function, including memory and task performance, spending too much time in it and too little time in slow wave makes you feel like you've been out partying all night long (can you say "vivid dreams all night long"??) and you end up feeling like you've been hit by a truck when you get up in the morning! You need that slow wave sleep for tissue repair and good hormone production.
I'm dedicating the next 6 weeks to healthy sleep habits (I figure that should be long enough to get things rolling). So, my sleep challenge is all about cultivating good "sleep hygiene" habits such as:
-earlier bedtimes (like, by 10:30).
-shutting the laptop off earlier in the evening (by 8:30) and turning the lights down.
- getting natural light first thing in the morning.
- practicing qigong for mental relaxation and also for better hormonal regulation (these methods work on the "kidney meridian" which, in Traditional Chinese Medicine, regulates hormone production). I'm convinced that qigong can cure most ills, but consistency is the key (and the thing I lack!)
-drinking mineral rich, nervous system supporting teas like nettle, oatstraw, rooibos, chamomile and horsetail throughout the day and evening.
-keeping caffeine minimal and only consuming it before noon (caffeine has a half life of at least 6 hours- and much longer if your liver is slow at clearing it- which means that the afternoon cup of coffee is still in your system in the evening, albeit at half strength, but that's enough to affect sleep quality.
-getting consistent moderate aerobic exercise (for me, brisk walking), which improves sleep.
I encourage you to join me, since good sleep is probably the most neglected thing we can do for our wellbeing (that and deep breathing, but that's another post:)
