Weekend Link Love – 21-Day Challenge Edition

By Mark Sisson
26 Comments

This year’s 21-Day Challenge contests are winding down, but there are still numerous opportunities to participate and win. Check them all out here and get your entries in before the deadlines!

Relevant Research

Some of you have undertaken a pledge to get less (or none at all) light at night. That’s a worthy goal, but I’d argue that even those of you doing something different for the Challenge – trying to lose weight, reduce stress, improve blood lipids, or anything, really –  may want to pay attention to your nocturnal light consumption. A sampling of recent research suggests too much artificial light at night can impact many avenues of health relevant to the Challenge:

Among elderly, those who keep a light on at night have higher triglycerides, higher LDL, more abdominal obesity, and more overall obesity. Trying to improve blood work? Try limiting light at night.

Even dim light at night exaggerates the normal inflammatory response to a stressor, injury, or pathogen. Trying to mitigate the effect of stress on your life? Limit light at night.

Blue light at night triggers the retinal cells that communicate with the limbic system of our brain that controls cognition and mood. Trying to get out of a funk? Limit light at night.

Helpful Blog Posts

Fitness gadgets can be helpful in your Challenge, but using an excessive number of them didn’t really help this woman.

Fuel For the Fire

Need a reason to stick with your “fewer carbs” goal? If you’ve got the right gut flora, eating too many just might cause your blood alcohol level to reach physiologically-relevant heights due to excessive fermentation. On second thought, that might be a reason to eat more carbs for some people.

Just because nature ain’t quite the same as it was (even just from fifty years ago) and even though human attempts to engineer it fail miserably doesn’t mean you shouldn’t be immersing yourself in it.

Avoiding soda for the Challenge? Good idea, because it’s rotting the collective teeth of the Appalachian mountain communities. Better than meth, at least.

Comment of the Week

The biggest advice that someone gave me about going primal is don’t be an A** hole. If you go out to a party, event, or friends house and they have non primal food, just eat small portions. Don’t be one of those guys that say “I cant eat that” or “I don’t eat that”. I have a couple vegan friends and it is very difficult to cook for them. One meal is not going to kill you or set you back that much.

– Great tips, not just for the Primal Blueprint Challenge but for life itself, from Josh

I constantly stress the correlation of light and sleep quality to patients of mine. Great articles about modifications that most people don’t make when adopting a “primal” lifestyle! Time to put away the TV, computer, phone and blackout the room for proper sleep.

I’ve had seasonal affective disorder (i.e. Difficulty adapting to long nights in the winter and tendency towards depression if I don’t get enough daylight) since I was a teenager, and I’m now 49, so I’m fascinated by Primal-inspired ideas about there being too much blue light coming at us from screens in the evening. I’m experimenting on cutting down on light exposure in the evenings as part of the 21-day challenge and looking forward to seeing if it helps me cope better as the nights draw in here in the UK. I also recently came across this article which talks… Read more »

Well, Louise, it does help cut down on the stress factor if you just embrace the wakeful period. I found a great little local store in Portland OR that sells full spectrum lights so I have one that I turn on in the AM to get my brain up and don’t use it at night, use a yellow light, still looking for an orange one that I can read with for some gentle light to coax my brain into the night. May have to go back to that little store on Mississippi Ave to find one? Now that I’m over… Read more »

I’m confused by the sweet potato gnocchi recipe–it calls for flour? But no flour is mentioned in the ingredients…

When it says to add the “flour” I believe the recipe is referring to the Arrowroot powder. The “Notes” at the bottom of the page say you can sub Tapioca flour for the Arrowroot.

Sounds like a good recipe — I think I’ll try this soon. I already have some very yummy home made tomato sauce in my freezer that I made using my garden tomatoes.

It’s paleo gnocchi, so there’s no grain flour in the recipe. Not sure where you got the impression that there would be flour in it, but it’s very unlikely that this website would knowingly share a recipe that included wheat flour.

From the recipe:

“5) Slowly add the flour and mix them until the dough is manageable*”

Thanks to PrimalGrandma for clarifying.

Is sleeping with an eyeshade adequate? I’ve never been sure if the problem is light in your eyes or also light on your skin. Our big windows would be hard to cover so I sleep with a blindfold. I’ve never known if that’s good enough.

Skin as well. It’s worth getting some blackout materials. In the summer (in the north!) I ended up using cardboard boxes flattened out and propped in the window frames this year!

Wow, I think you’d have to be sleeping out in the open during the day for light on your skin to affect your sleep or your health. Are we talking about a little street light filtering through the blinds at night, light from a digital clock, or trying to get some shut-eye on the beach at noon before pulling an all-night shift?

Love the info about sleep and light–and wow, those are shocking stats about the elderly! And thanks so much for mentioning my Easy, Smoky BBQ Kale Chips today as well–a reminder that I need to make some more! 😀

Attended a birthday party for a good friend on Saturday. The cake was so sugary that it tasted un-natural. I found that I wasn’t wanting a second slice at all.

On the sleep issue, maybe the old four-poster bed with heavy drapes should make a comeback.

Don’t think I’ll be doing a “workout” today. Wrestling – often literally – with sheep all morning is hard work for both body and temper. Thank God, I’m a country boy!

Not sure if this was mentioned but a good way to avoid the particular frequency of blue light that disrupts one’s sleep cycle is to use a program called f.lux on your computer which filters out the relevant frequency of light from your monitor depending on the time of day. I have noticed much improved sleep since using it. Go here for a free download and a good technical explanation of why it works.

I have this on my PC, works well to keep me in the nighttime mode when the body/brain seems to think that the middle of the night is a good time to wake and worry. Playing solitaire is boring but enough of a distraction to put me right back to sleep. I wear blue blockers as well, it’s not fire light but more like ember light.

Installed this many months ago and just realized it wasn’t on anymore for some reason. Went to the link and reinstalled it in about 15 seconds. Glad to have it back!

There is a lot of wild nature in my So Cal urban yard. More scary wild animals than I have ever experienced in the thousands of miles of backpacking I have done. Just the other night I had to listen to what sounded like a bird being strangled to death, its poor pitiful screams slowly tapering to silence. I hear this now and then. I see all kinds of footprints on my deck. Greasy footprints from the various mammals feasting on our avocado trees. Skunks sometimes just wander into the house. What do you do when you see a skunk… Read more »

You may need to install some doors to keep the skunks out! 🙂

There’s an ad campaign for soda: Rots your teeth, but it’s better than meth! About the night-time light . . . I have a newborn and we cosleep. We still have a bit of trouble coordinating the latch on while lying down at night and so I keep a nightlight on to help. I could keep it dimmer, but my eyesight is poor and if I have to fumble for glasses before latching him on, he gets fussy and frantic (he goes from 0 to frantic faster than some babies). Any advice from other mothers (or fathers or others) out… Read more »

Had the same problem with my firstborn. You can get an inexpensive touch switch at the hardware store to attach to your bedside lamp. You just plug the lamp into it and plug it in, and then place the little round touchpad right next to the lamp. It has two benefits. The first is that it turns your lamp into a three-way bulb, not matter what the wattage. On a 60 watt bulb the first touch gives you something like 15 watts of light – enough to figure out a latch without getting really woken up and waking up anyone… Read more »

Would love any suggestions for someone who copes with insomnia by reading (and thus getting exposed to light in the middle of the night). Not reading is not probably going to be an acceptable suggestion. Anyone think blue-blocker glasses would help? I do make sure the light is incandescent and have red shades on the lamp.

A kindle paperwhite might work. I have a very old kindle and the light is nothing like a laptop or tablet, it’s a duller light and way better than turning on a light.

“One meal won’t set you back”…

Going from past experience, depending on your usual primal strictness and particular intolerances, it may well make you:
Nauseous, bloated, lethargic, break out in pimples, have runny stools, be grumpy, be depressed, and so on. Yes I mean one meal, yes I’m talking first hand experience, and yes the effects are even notable by others.

I’ll just be an *asshole* thanks.
