There are many reasons people choose yoga as their main form of exercise. It stretches out the muscles, is easy on the joints, relaxes the mind, and hones the breathing skills. Yoga is also a form of meditation. Since there are many people who drink tea during meditation, it only seems logical that tea would be beneficial after yoga.
Tea can help slowly bring the mind back to reality after the peaceful meditation of yoga. It is the perfect way to end a rejuvenating workout.
