Laughter, if used generously, can help drain the stress away. The moment it arises, all our hardnesses yield, all our irritations and resentments slip away, and a sunny spirit takes their place. Laughing can lower your blood pressure, increase vascular flow, and boost the immune system. It gives the diaphragm, abdominal, intercostal, respiratory accessory, and facial muscles a complete workout. Some people, depending on how they laugh, may even use their arm, leg, and back muscles when laughing.
Endorphins are neurotransmitters that attach to the same receptors in our brains as the opiates.
Opiate drugs not only cause us to lose touch with reality, but they also numb pain. They had significant results that showed increased activity in IFN after watching the funny video and on into the following day. This could be very important in the research for cancer since it also fights against tumorous cells. Laughter's ability to be a pain reliever and its ability to fight tumorous cells have added an exciting new area of research to cancer. Perhaps, if people would start relieving their stress through laughter before they get cancer, there might be a reduction in the number of cancer patients altogether.
