Ancestral Sleep

UCLA recently led a sleep study where they gave one of the last remaining hunter-gatherer cultures some tracking devices, and learned some interesting things.

Participants stayed awake an average of 3 hours and 20 minutes after sunset.
Average sleep time was 6 hours and 25 minutes. (6 hours in the summer, 7 in winter)
Waking time occured at the lowest temperature of the 24-hour period, even after sunrise
Napping is rare
Insomnia is extremely rare

Incredibly, it sounds like temperature may be the leading factor in better sleep. I’m thinking maybe it’s time to get a OOLER programmable sleep system.

What are the most nutrient dense foods? How is it calculated?

This video is a long time favorite of many nutrition enthusiasts. It covers the topic of the puzzling problem of calculating nutrient density in foods, accounting for calories and water weight. The results presented are amazing.

Rebound Relationships are Healthy

Dr Ramani says the research on rebound relationships shows they aren’t as bad as once thought. They act like a palette cleanser. They often reboot people and get the previous relationship off a person’s mind so they don’t sit around ruminating. Importantly, this contradicts what is widely considered to be common knowledge that rebound romantic relationships aren’t healthy. Apparently they can be.

NAD+ NADH Ratio for Epilepsy

Post author By Justin Reinhart
Post date September 7, 2020

“One of the proposed benefits of the ketogenic diet, particularly for the anti-seizure effects that it has for epileptics, is really that it shifts this redox potential. And that the additional—I’m pretty sure it’s NAD+ goes up. NAD+ over NADH, when you’re on the ketogenic diet for a while, that it’s actually the excess NAD+ that is providing the therapeutic benefit. This is one of the proposed mechanisms of action for the benefit of the ketogenic diet in something like epilepsy.”
—Dr. Trey Suntrup, PhD in physics and engineering; Healthy Rebellion Radio – Salty Talk 17

Dr. Trey Suntrup was discussing this off the top of his head and he mentioned there is the remote possibility he may have the ratio backwards. He said he is pretty sure it is NAD+ that goes up but anyone viewing this citation should review the literature and make sure it’s not backwards.
