Sometimes there is a hormonal explanation
But to do anything about it is usually a case of the cure is worse than the disease.
Hormones are in a constant state of change anyway and therefore so are the problems they cause. LOL. Still, it would be worse to be a man and not have any hormones to rage

Personally I think if you can keep your life in time with the sun and the birdies chirping (or stopping) you get on better in total general health
