Getting Stronger is a health blog on hormesis, the idea that small stresses build resilience, covering vision, cold exposure, and exercise.
HN commenters recommend it as an excellent site on hormesis applied to problems like eyesight and back pain, and as a good health and fitness blog.
The TLDR is that a lot of people have very high myopia that causes severe eyeball elongation, which then causes retinal damage/detachment, which sadly could progress into blindness..
I myself was -5.75 and -6.25 with some non-negligible cylinders. I experienced discomfort when looking at my phone phone and reading book with my glasses on. I General check up said that my eyeball pressure and all were normal, but I know the discomfort is nothing good and can be quite serious. I read up online and found out that myopia could cause eyeball elongation, which could cause discomfort and ultimately could cause retinal damage/detachment. The discomfort I was experiencing was probably due to my elongated eyeball.
I prayed and began looking for way to work around my myopic eyes without having to get yet another thicker glasses... And I'm super thankful to have found out about this life-changing video by Todd Becker on how to reverse myopia: https://www.youtube.com/watch?v=x5Efg42-Qn0. The TLDR is that eyeball elongation (and hence myopic eyes) can be reversed in a way very similar to how strength training is conducted (hormesis). You simply need to keep wearing reduced prescription and do eye-focus exercises regularly.
It sounds too good to be true, doesn't it? I was scared too at first, and when I went to a glasses store to get a lower prescription glasses, the store attendant warned me too. But I went ahead anyway. My latest eyes exam before the attempt (back in August 2021) was…
Interesting -- have you heard of Nassim Taleb's book "Antifragile"? He talks about weightlifting vs. "traditional" aerobic exercise.
I guess this may be common knowledge in some exercise circles... but it is probably not common knowledge with the general public.
This article has a summary, though there may be better ones:

How does the barbell strategy apply to health? A great example is combining occasional, high intensity weight lifting or interval training, alternating with long stretches of rest, recovery and “doing nothing”. The intermittent stress of lifting an extreme weight pushes the body to overcompensate and prepare for an even greater future challenge, but the interlude of rest and recovery is restorative and avoids the downside of chronic overuse. We can extend this idea of a bimodal “barbell” strategy to practices such as intermittent fasting or cold showers. The barbell strategy is the exact opposite of the conventional wisdom to engage in moderate aerobic exercise on the treadmill every day, or to eat regular small meals throughout the day.
Actually, yes. Most doctors would call it fringe science, but I've been able to improve my eyesight with what's called Plus Lens Therapy. It has you wear glasses that are the opposite of those you've been subscribed, or that are significantly less strong, and using them while actively trying to focus at the edge of blur, e.g. by reading a book and keeping it far enough away so it's ever so slightly blurry but not too blurry either, forcing your eyes to clear the image. It's not clear why it works – do your eyes actually start changing their shape, or is it simply the eye muscles that get stronger? – but if you're willing to put in the months and months of effort it requires, for many it does help.

I never suggested that there was scientific evidence that taking showers has health benefits. I simply indicated that I've started taking cold showers, that I'm getting value out of doing so and that perhaps readers should try taking a cold shower and seeing if it also gives them value.
I've linked to another blog post that suggests there are health benefits - I encourage you to read it, perhaps look for others and form your own opinion.

Although many people recommend eating many small meals, it doesn't let your insulin levels return to baseline levels. As a result, you're training your body to not get its energy from body fat.
It's a lot to read, but this article explains it: http://gettingstronger.org/diet/
Basically, we need to gradually give up snacking if we want to lose weight, then just stick to 3 meals a day, and if you're ambitious do intermittent fasting.
I'm very interested in health and fitness and often lose hours at Mark's Daily Apple (primal lifestyle and health blog): http://www.marksdailyapple.com/tag/dear-mark/
The Getting Stronger blog is another wonderful health and fitness blog which focuses on training the mind to thrive in difficult conditions, though it has really amazing insights on diet and training as well: http://gettingstronger.org/about-this-blog/
