This seems like sound general advice, although, lately I'm not very impressed with FDA standards. This is the same group that has approved flavored e-cigarettes with propylene glycol, BPA-coated (and later BPS-coated) food containers and teflon-coated cookware, carrageenan in meats, hydrogenated fa...

I do not want to become obsessive,,, I suspect keto is not an absolute requirement for avoiding Alzheimer's, especially if you are not spiking insulin and glucose with sugar and simple carbs. However, what I picked up on in your post is the comment about not wanting to become obsessive. I don't kno...

Does anyone wear a fitbit? if so, how much DEEP sleep do you get each night? I wear an Oura ring, and it tells me I average 58 minutes of deep sleep. However, all of the commercially available sleep trackers are only about 50-60% correlated with polysomnography, which is what is used in sleep labs....

If someone is infected with these viruses, this news is only going to scare them more because there`s no cure for the virus. There are vaccines against Herpes Zoster (the shingles virus) and antivirals that suppress outbreaks of other herpes viruses. Antivirals like valacycovir cross the blood/brai...

What is the mechanism by which the Oura ring tracks deep sleep? Oura says it analyzes sleep by measuring the dynamics of heart rate, pulse strength, body temperature and movement. They use proprietary algorithms combine these measurements into a detailed picture of sleep patterns. Because the ring ...

I tend to associate elevated cortisol with elevated HR. Why do you think that high cortisol is lowering your heart rate - or am I misunderstanding your thought process? I agree that elevated cortisol is associated with elevated HR. My heart rate drops at night to around 48 to 52 bpm; however, that ...

A somewhat off the wall predictor for AD... People with "low scam awareness" (evaluated with a questionnaire about con-game tactics) at baseline showed a 56% higher risk of developing Alzheimer's disease dementia and a 47% higher risk of mild cognitive impairment over about 6 years, accor...

Peter Attia's email this morning referenced a study comparing time-restricted feeding windows . This study showed shifting a group of subjects to an early 18/6 TRF schedule (8 a.m. to 2 p.m.) had a number of benefits: Avoiding food for several hours (in this case, more than 8 hours) before bed may h...

Female, 67 years old. I've been doing 4 to 5 CrossFit sessions per week since 2013. I've modified some of the exercises in the last year to minimize the risk of arthritis (e.g., rowing or cycling instead of running; stepping up onto boxes instead of jumping up). On recovery days, I do mobility work ...

Unhappily, Dr Walker doesn't have many ideas about hacking the stages of sleep. He does suggest that a hot bath just before bed increases the amount of deep sleep by 10 or 15% but I haven't noticed any impact as yet. So is there any way, I wonder, that I can intervene to increase the likelihood of ...
