Prenatal Yoga is a style designed for expecting women to practice regardless of their due date. The nature of stretching, controlled breathing and mental focus offers a variety of benefits to expectant mothers. Prenatal Yoga may reduce stress level and improve sleep pattern during pregnancy. It may also alleviate physical discomfort such as nausea, headaches and lower back pain. Another benefit typically associated with Prenatal Yoga is the way the breathing techniques and state of self-awareness learned can help during delivery. Not to forget it can also increase strength and flexibility in the muscles used during childbirth.
