We know that depression is linked to exercise, sleep and diet. The actual mechanisms aren't clear but it could be due to BDNF, increased microcondrial health, brain volume, blood flow, anti-inflammatory, etc.
So it might be that depression is just correlated to poor survival rates, where the actual causal factors are sleep, diet and exercise.

In this paper they focus on inflammation.

Which lines up with the fact exercise, sleep and diet all act as anti-inflammatory.

Since reddit has a hard on against, sleep, diet and exercise here are a few relevant studies demonstrating the link to depression.
​
>Aerobic exercises, including jogging, swimming, cycling, walking, gardening, and dancing, have been proved to reduce anxiety and depression.3 These improvements in mood are proposed to be caused by exercise-induced increase in blood circulation to the brain and by an influence on the hypothalamic-pituitary-adrenal (HPA) axis and, thus, on the physiologic reactivity to stress.3 This physiologic influence is probably mediated by the communication of the HPA axis with several regions of the brain, including the limbic system, which controls motivation and mood; the amygdala, which generates fear in response to stress; and the hippocampus, which plays an important part in memory formation as well as in mood and motivation.

This is false. Depression is linked to exercise, sleep, and diet but they are don't cause major depreesion. You can have great sleep, diet, and exercise habits and still develop major depression which increases your inflammatory markers. I actually had a case of major depression that popped up and my inflammatory markers were high even though I was in excellent shape. Major depression can increase inflammation regardless of your habits. Lesser forms of depression can get better with or even treated with working out and better sleep but not major depression.

platelet-to-lymphocyte ratio is one of the biomarkers for inflammation. Exercise, sleep, and diet don't affect that ratio. Only major depression does. Your assumptions are wrong here.

It doesn't mention the type of depression and it only REDUCES not completely treats major depression. It has to be completed treated not just reduced to a lesser degree of depression. Meds are necessary for treatment. Like wise you post a bunch of stuff and are too illeterate to know that it shows that exercise is good but isn't a cure all. Meds are needed in many cases especially for major depression due to chemotherapy. You sound like you're playing doctor. right now.
>University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression
Manages. Not cures or treats.
>In conclusion, PA is effective for improving depression and anxiety across a very wide range of populations.
Improves depression and anxiety, does not cure or treat.
>Sleep, exercise and depression are all linked to brain volume
Linked doesn't mean anything. Poverty is also linked to lack of sleep, depression, and exercise. I'm surprised you haven't pushed hustle culture BS here too.
>Exercise has massive effects on mitochondria, which might be partly a mechanism in relation to depression.
Linked just means it appears in relation to. We don't know the cause or what the true fix is. But the best medical practices is talk therapy alongside medication as needed.

The fact you conflate proper sleep with insomnia is stupid. You can't "proper sleep habits" your way out of clinically diagnosed insomnia. It doesn't mean "goes to bed late".
The fact that you would post stuff that doesn't prove your point and yet be too illiterate to understand what you are reading is wild

I agree

In your post you keep on referring to different forms of depression.
Major depressive disorders is just the name for basic normal depression. All the other types are worse or specialist types of depression.

Seems like exercise does acutely effect the ratio.

Again major depression is the normal basic depression everyone is talking about. If it was some other type they would specify.
The current view is nothing "cures" depression. So pretty much every study will just talk about treating it.

Sure people can use meds. It's like when I cut myself, I might take a painkiller. While it isn't fixing the underlying issue, it does help.
​
>The fact that you would post stuff that doesn't prove your point and yet be too illiterate to understand what you are reading is wild
You are the one who thinks that "major" depression is like some super duper serious form of depression, rather than just the medical name for basic clinical depression.
You are the one who doesn't know that every study on depression treatment will just talk about treating it rather than curing it.
