Health Benefits of Donating

I have no idea of the health benefits of donating (though I have looked it up online) but I’ve noticed that my allergy-related issues (my sinuses seem to exist only to make life harder than it need be) but since I began donating symptoms seem to have lessened.

That being said, also since I’ve been donating I drink more water more consistently (typically three to five cups a day).

I also eat better (in terms of greens like spinach, kale, onions, and a lot of EV olive oil, etc) so maybe it’s a combination of things?
