Laugher is said to be the cure for many things, including fertility. Studies have shown that those with lower stress levels had a higher rate of success in fertility. Laughter is an easy way to relieve stress and remove the mind from the difficulties involved with infertility. One clinic in Dallas even offers Laughter Yoga to their patients. Laughter yoga relaxes the individual and their body. The sessions last about an hour long. Yoga exercises utilize the face and body muscles involved with smiling and laughing. The sessions were created to help couples and individuals escape their stress during the day through laugher therapy.
