Yoga for an immune boost

Yoga has now been shown to give an immune boost to breast cancer survivors even as it promotes psychological well-being and delivering the physical output equivalent to a moderate-intensity exercise.

Yoga gives immune boost to breast cancer survivors

I've been practicing yoga for over 15 years now, albeit only in classes.  Apart from walking, yoga is my principal form of exercise.  I'm lucky to have a teacher who understands middle-aged bodies so we're not endlessly doing upside down dog and sun salutations.    Instead he aims to get us to a state of energized relaxation and often incorporates elements of qi gong.

For those who have never tried yoga or for beginners, here are some of the physiological and psychological health benefits of yoga.  For the middle-aged, I believe yoga is better than most other forms of exercise because of the low risk of injury, the focus on the breath and the relaxed nature of the "asanas" or postures that build strength and balance. 

According to medical scientists, yoga therapy is successful because of the balance created in the nervous and endocrine systems which directly influences all the other systems and organs of the body.
