Shirshasana (the headstand) is the king of all yoga poses. I try to do one for 3-5 minutes daily and here is why:

  1. It flushes nutrients to the face helping your skin to glow. 
  2. Adrenal glands are flushed and detoxified, decreasing depression. 
  3. It increases blood flow and nutrients to the scalp delaying the onset of grey hairs (some say it can even reverse it back to its old colour!)
  4. Improves circulation.
  5. Strengthen core muscles. 

 You should first learn a headstand from a qualified teacher.  They are not recommended if you have neck injuries, extremely high blood pressure, ear and eye problems, if you are menstruating, or have acid reflux.
