HEADSTAND is also called the King of all Asanas in yoga. Headstands stimulate and provide refreshed blood to the pituitary and hypothalamus glands. These glands are vital to our well-being, and are considered the master glands that regulate all other glands in the body (thyroid, pineal, and adrenals). Headstand relieves pressure in your lower back and your lower body’s veins, particularly those in your legs. Headstand gives your lungs a workout, making you breathe deeper. It makes you think clear and improves sleep. In yoga therapy headstand is also used to treat eye related problems.
