In our day to day life when we do several activities at one time, working in hotter environment or when there is change in weather. We tend to get tired as our body works in and out. Hence we need to put some time to cool down and rest. Sheetali Pranayama is yogic way to cool down your body. Sheetali means “the one that cools you down”. ‘Sheet’ in Sanskrit means cold. Also this pranayama is called Sheetali as when we do this pranayama we make a small hissing sound like “Si…Si..”. Doing this activity regularly will relax and remove excess body heat.
