Self-healing is not about completely autonomous healing; it is about healing by stimulation of the body's self-repair processes, which in some cases can be achieved by simply reducing stress.

Significantly greater gains in strength occurred during this second stage for those individuals, even though this stage was shorter in duration (4 weeks). The participants in this classic study increased their strength gains due to one main reason. They strongly believed it wo...
