Actually you do. Major depression causes your lymphocytes to increase with relation to platelets. Meaning that you're more susceptible to cardiac events and general illness with major depression. The fact that major depression occurs in cancer patients could point to a host of issues. I would expect to see link between cancer spread and major depression.

This is opposed to less severe forms of depression that do not affect your lymphocytes and platelet ratio.

So yes. We do need scientists to figure this out.

>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.

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.

>“Depression should not be discounted. This study shows the strong link between depression and inflammation, with both related to poor outcomes

https://news.osu.edu/depression-linked-to-deadly-inflammation-in-lung-cancer-patients/

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

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.

We have studies showing that exercise is just as if not more effective as medicine and therapy in treating depression

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.

>Sleep is really important, if you aren't sleeping properly you have have a tenfold higher risk of depression,

People with insomnia , for example, may have a tenfold higher risk of developing depression From

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

Decaf does have some health benefits if you don't mind the taste!
