That’s a long list. Not all research is good research, or shows the effect you’re looking for. Where did this come from?

Do you use red light therapy? For what? How often? Where do you focus it? I did manage to get some red light masks although I find it hard to fit into my routine

Would also be interested in a routine that makes sense.

People use habit stacking or habit chaining to get it into their routines - helps me tremendously to make new things a daily habit.

But this depends on how often red light therapy might be actually helpful.

Isn’t simply getting enough outdoor sunlight just as good as red light therapy.

Yes, assuming you get exactly the right amount and somehow also never too much of the bad UV light. It's a finicky thing to get right, but bottom line yes.
