By lowering cortisol levels, yoga can help reduce stress. Even just three months of consistent practice can cause a permanent "significant decrease of perceived stress." Practicing yoga is also associated with increased brain GABA levels, which can improve mood and decrease anxiety.
A growing body of research suggests that yoga can support male sexual health. In fact, a 2010 study published by The Journal of Sexual Medicine says that yoga can significantly improve literally all domains of sexual function: desire, intercourse satisfaction, performance, confidence, partner synchronization, erection, ejaculatory control, and orgasm. And all that was required among research participants was just 12 weeks of practice.
Yoga appears to be equally beneficial for both healthy and ailed individuals in terms of quality of life and general well-being. For example, among diseased populations, yoga has been shown to improve fatigue, erectile dysfunction, and urinary incontinence in prostate cancer patients, and speed up recovery in stroke patients. And among healthy populations, yoga may can improve a variety of health-related outcomes — as well as or even better than strength exercises can.
