We have already heard that sleeping helps to heal, but sleeping helps grow too. Even an infant’s growth is affected by the quality and quantity of sleep they are getting.

  • Another position is when you lay back on your back, like a soldier sleeps, straight and long! Also, your hands and feet must be straight down. This posture not only helps increase your height but also helps in encouraging wrinkles to form.
