The central nervous system and the sensory organs, which also include the skin, develop from the primary cell layer when we are still embryos. This allows the unborn child to interact with its environment via the skin even while still in the womb.
Touch is essential for human’s well-being. Receiving loving touches is essential for babies and children. Touch promotes the development of the brain and the distribution of growth hormones. Adults also benefit from gentle caresses. These release endorphins (happiness hormones) and reduce blood pressure.
Touch has a calming effect and has a positive influence on our emotional life. If we are stressed or lack human closeness, the skin often reacts by turning blotchy, becoming dry or developing impurities.
All forms of touch – whether pleasant or unpleasant – are perceived first by our skin. The various receptors conduct these sensations on to our brain. Every form of physical contact has an effect on our psyche: hormones and messenger substances are released. This is why we generally perceive hugs, caresses and massages as pleasant and positive.
