I have just read this book and found it very interesting and helpful: https://www.simonandschuster.com/books/Why-We-Sleep/Matthew-...

I've seen this book talked about a lot. However, I also have heard that there is some big holes in the research. Take a look online.

Running improved my sleep quality dramatically. Now the problem is, that if I take a day off running, my sleeping suffers. Curious if people that do weight lifting (which I'm considering) get great sleeps? Maybe I can alternate between cardio and weight lifting each day?

I tried weight lifting/strength training for about a year and never really noticed an improvement in sleep quality. However, it was still a net positive in the strength/overall daily energy department.

I used to bike a lot, stopped after a leg/back injury (not from biking), but I picked up an eBike about 3 years ago and absolutely love it. The pedal assist takes enough stress off my leg that I can keep it on the lowest setting and ride for hours, which feels really, really good and does actually help with sleep that night. This, of course, is weather/season dependent but I relish the times when I can just hop on after work and go somewhere.

The generations in my family are full of people who had dementia/Alzheimer's/auto-immune disorders. They all had anxiety, and they all had sleep disorders - I'm certain there is a connection among it all. I joined a Stanford study and had a spinal tap sample submitted for testing - in theory I am "unlikely" to develop anything for the next 20 years - but that only gets me to my late 60's :(

Same, except we also have digestive issues. I'm really hoping a paleo diet and good probiotics will save me. It's already helped me a lot. I'll let you know in 40 years if it prevents me from getting Alzheimer's.

Some people seem to need a lot less sleep than others with no deleterious health effects. It would be very interesting to find out why.

> with no deleterious health effects Is that actually the case? do we have long term data on these people? or are we just going off of "I feel fine on 5 hours of sleep" stories? Or are you only referring to day to day health effects?

There's been research on it, although not as much as I wish. I'm one of those people who simply needs more sleep than the average, as does my dad... meanwhile, my mother chugs away just fine on 5 hours or so, and is in better health than either of we men are.

People who accomplish a great deal are often one of these "short sleepers" who can subsist on 5 or even 4 hours of sleep a night; think top-of-their-field salesmen, CEOs, and so on. They simply have more time to get things done, and don't have the problem longer sleepers do that getting 4-5 hours on a regular basis would start to affect their performance in every area of life, not to mention their health.

From what I've found, being overweight negatively affects sleep. As far as I can tell, the extra weight simply makes it hard to breathe at night, leading to apnea. This can then cause depression and anxiety, depression because you wake up tired and feeling awful every single day and anxiety because you may wake up with night terrors after suffocating in your sleep. At least it's easy to get a home sleep apnea test an…

Easy to get, hard to get used to for many. It’s common for doctors to offer little to no support after prescribing the machine.

If you’re supplementing probiotics, there is some research about inulin to talk through with your doctor. There’s a chance that inulin is carcinogenic even at lower doses. A lower dosage might be 4g and a typical probiotic is 200g. Reasons to be wary of this research, including: -The rodent-to-human study element -causation v correlation -sample size Reasons to take this research seriously: -Probiotic supplements are…

Probiotics usually refers to bacteria, inulin and other indigestible starches are usually referred to as prebiotics.

Wasn't there supposed to be a smart watch out there you could set a window of time you wanted to wake up like "between 6:30 and 7:00" where it would use the sleep tracking to pick the optimal time to wake you up like at the end of a REM cycle? I feel like I must have hallucinated this because I'm wearing a smart watch (fitbit) now and no such feature exists.

I'm wearing a fitbit (charge 6) now, and I still have this feature. It's called "Smart wake" https://gadgetsandwearables.com/2021/07/09/fitbit-smart-wake...

A-ha that answers my question

>while the new Inspire 2 gives insights into sleep stages, the Smart Wake feature is absent. We’re not sure why this is. Hopefully it will come via a software update.

Walking. Walk 3 miles a day. It gives you a drastically different set of benefits from running, and you can walk all day without worry of overtraining. Running is great too. But be careful of doing it too much. Overtraining can break down your immune system and make you more susceptible to disease.

I wonder if it only works for a dedicated walking time (e.g. walk for 3 miles nonstop) or also for bursts of short walking during the day. I consistently get 3-5 miles of walking per day due to chasing kids around, taking short breaks during work, and doing chores, but rarely actually have a 30+ min sustained walk.

Some people seem to need a lot less sleep than others with no deleterious health effects. It would be very interesting to find out why.

There are a very small minority that seem to have a genetic component requiring less sleep for them (4-6hr). https://www.ucsf.edu/news/2018/03/410051/scientists-discover...

A subsequent study has not found any link between the ADRB1/DEC2/other gene mutations and various sleep conditions:

- https://pmc.ncbi.nlm.nih.gov/articles/PMC9499244/

I am incapable of sleeping more than about 5.5 hours (unless I'm severely sleep deprived). So to me it seems likely that FNSS (familial natural short sleep) is a thing, but more research is needed I guess.
