Question

can anybody tell to increase healing system of our body?

Answer 1

I assume you're question is more about regeneration? And how do we improve it?

Well the wound healing process is not only complex but also fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.

Preventing such diseases from occurring is one way to improve your 'healing system' of your body

The body is endlessly working to repair and regenerate itself. This happens to a great extent when we are sleeping — when our body’s energy is only minimally being used to sustain autonomic nervous system function (that is, involuntary functions such as heart beat), and most of it can be directed toward restorative and healing processes.

Shorting oneself on sleep is known to weaken the immune system. To get energy the artificial way (say, through caffeine) is to do the body a great disservice, by denying it the amount of rest that will make all its systems, including the immune system and the body’s healing and restorative processes, work at their best.

So sleep is also another option too

Diet also plays a big role when it comes nutrients and minerals
