Has anyone here managed to reduce the frequency of waking to pee at night (e.g. by controlling liquid intake)? For me it’s 2 times/ night with difficulty going back to sleep so fairly huge disturbance.

oxygen deprivation can make you produce more urine, check if you have sleep apnea?

>The biggest game changer: Sunlight in your eyes within 30 minutes of waking up. Try morning walks for 1 week (without sunglasses) and your life will be changed. For me I had to also really avoid light at night. F.lux or Windows Night Mode is not enough. You gotta suffer with strong indoor lightblocker glasses, or use e-ink or something at night. And in the winter there sometimes isn't enough sun. You need a LOT of l…

I've thought about trying to simulate an outdoors awakening. With Phillips hue lights you can simulate the sunrise, then a smart thermostat for having the air become warmer. You could play bird chirping noises as well. Can't do much about making the air smell different in the morning like it does outdoors.

you can definitely have one of those perfume sprayers, and there's bound to be lots of companies making a "morning woods" fragrance somewhere that you can plug in there

For people with sleep disorders.

Sure but most people in the west have chronically low serum vitamin d levels. Proper D levels have a ton of other known beneficial effects including protecting against several types of cancer, proper calcium regulation, disease prevention etc etc. The current recommendation is keeping serum levels at least above 30, and more like 40-60. Many many people aren’t in that range. https://pubmed.ncbi.nlm.nih.gov/32679784/

do you find out your serum levels through a regular blood test at the doctor, or is there something specific you need to request?

If anyone is struggling with sleep, I highly recommend episode 1-3 of the Huberman Lab podcast ( https://www.youtube.com/watch?v=H-XfCl-HpRM ), it has literally changed my life. Dr. Huberman is a Neurobiologist at Stanford and explains the science of sleep vs just telling you to not look at bright screens at night. I struggled with sleeping for 20+ years, now I easily wake up early. The biggest game changer: Sunlight…

What if you're doing night shifts?

Another one of these "eggs are good"/"eggs are bad" flip flops that happens every few years. Before this the "science" was that too much vitamin D disrupts sleep. In fact it seems to have disrupted mine. It's 4AM, and I can't sleep even after taking a MJ brownie. I take 2000IUs daily and my values are "normal" now. And yet I've been suffering from insomnia shortly after I started taking this supplement. Who do I beli…

take them early in the morning, not at evening or night, try drinking milk as well.

Can anyone find the effect size in this study? When it is missing, I suspect that it is small, and that in turn leads me to suspect p-hacking.

Mean and standard deviation for PSQI at the end of the study.

Vitamin D group: 6.75 (2.97) Placebo group: 9.73 (3.04)

Cohen's D: 0.99 (>0.8 is regarded a large effect size)

Side note: The translation "Petersburg’s Sleep Index" instead of "Pittsburgh Sleep Quality Index" just cracks me up though! =)

> Sunlight in your eyes within 30 minutes of waking up. I live in Florida - our license plates don’t call it the sunshine state for nothing - but even here the sun doesn’t rise at 5am. Short of blasting my retinas with bright lights soon after reveille, I don’t see where I’m going to obtain sunlight this early in the morning. (It’s 07:21 local time now, and the sun is just now coming up. It’ll be a beautiful sunrise,…

Well, yes, waking up in the the middle of the night is not great for your ability to have a normal sleep schedule.

What really worked for me is having a full glass of water on my bed stand. Wake up and drink the entire glass. It really works immediately for me.

I think the parent comment is aimed at people who have trouble waking up because they didn't get enough sleep, not just because they're sleepy.

Thanks. That's pretty compelling.

How would someone control their cortisol levels? Maslow's hierarchy of needs, medical/pharma interventions, and/or something else?

More aerobic exercise, less anerobic exercise, more meditation, etc.

Anaerobic exercise may have a temporary bad effect on cortisol, how are the long-term effects though? In moderation I suspect it is a net positive long-term.
