Yoga, in addition to exercising the muscles, will help relax, release tension and connect with the baby. We will learn what are the benefits of doing this activity during pregnancy and what precautions should be taken. Yoga is an ancient technique from India whose meaning in Spanish is "to unite." Yoga means union of body, mind and spirit through physical and mental exercises. The combination of yoga and other cardiovascular exercises such as walking or swimming are ideal during pregnancy, not only because they keep you in shape, but they also strengthen the muscles, give greater flexibility to the joints, improve circulation, and give strength and vitality. Yoga also helps to improve breathing and relax, two very useful benefits for when the day of delivery arrives. One of the pillars of Yoga is breathing. The basis of it is to breathe deeply through the nose very slowly until the lungs are filled with air and then exhale until it is completely released. Relaxation facilitates the natural progress of labor and consequently it is much shorter and less painful. The practice of this discipline provides greater strength and elasticity to the muscles and joints of the pelvic region, as well as helps to strengthen the dorsal and pectoral muscles, which favor the mother's posture during the last months of pregnancy and the breastfeeding period. With the practice of breathing exercises, the blood supply to both the mother and the baby is improved, a state of relaxation is achieved that contributes to psychological balance and this will result in a better experience during childbirth.
