When the body is touched receptors in the skin send messages to the brain causing the release of chemicals such as endorphins. This produces a sense of relaxation and well-being and can also provide pain relief. Massage also improves the flow of blood and lymph fluid, helps eliminate waste products from the body, relaxes the muscles – and can help regulate hormone production and stimulate the immune system. Many studies have demonstrated the wide-ranging benefits of massage. As well as the benefits mentioned above, it is useful for specific ailments such as asthma, depression, back and neck pain, insomnia, immune deficiency disorders and diabetes. It can be helpful during pregnancy and labour and is also used to help premature babies thrive. Massage is often a part of therapy for people with cancer since it promotes relaxation and a sense of well-being.
