Not really. Good quality sleep, regular physical exercises and vitamin D can reduce risk of depressive episode.
Regular healthy sex is part of the 'healthy lifestyle' is in not?
Our bodies and minds were designed from the beginning to crave, and value sexual activity.
Not having regular sex, to me anyway, is quite unhealthy.
I recognize there are people throughout history that have practiced chastity, and if made as a conscious choice, I suppose SOME people can live with it.
I'm not sure I understand the way that civilization has evolved. As we left behind the dark ages of the 1950s, and let the light in on repressive sexual attitudes (As an aside: More people were married then, and generally married people have more sex...or at least they should), and started to enjoy the concept of free love, I think people in general were happier.
Now, while we celebrate every possible sexual union, why are sexual encounters falling? Why do teenagers refrain from sex far more than their parent's generation?
Why have we turned sex into a contract-like mine field requiring multiple levels of sign off, as things become more heated?
I suggest we've taken much of the fun and playfulness out of sex. The pure pleasure of being WITH another person...in the moment...looking for that 'high' that only come with true sexual engagement.
Is it not possible...that maybe the lack of sex, or the re-complicating of sex, could be part of the reason people are more depressed?
