> Highest suicide rates occur during the spring, around the vernal equinox not around the darkest time of the year.

If you don't take vitamin D pills or consume (lots of) cod liver oil, then your vitamin D levels will be lowest in the spring. If I remember correctly, at around 60 degrees north, you have to wait until the end of April until you get vitamin D from the sun.

Interesting. Are there any studies on this lowest-in-spring observation?

Rhonda Patrick talks about vitamin D quite bit (she is awesome). I'm coming up empty on seasonal relationships but it would surprise me if she hasn't mentioned something about it.

It does make sense though. If you're not taking supplements and the sun isn't direct enough to make any on your own until late April then late spring would be the longest point in the year you've gone without proper sunlight.
