Why it works: The hot steam moistens the nasal passages, thus clearing your blocked nose and opens up congested sinuses allowing you to breathe more easily. The hot steam circulating through your body causes the temperature to rise and consequently blood vessels to dilate. This causes an improvement in blood circulation, opens up the pores of your skin and restores colour. Also, your immune system notices this rise in temperature and increases the production and action of WBCs leading to a stronger resistance against bacteria and germs.
How it works: Put a towel over your head and inhale steam from a bowl of boiling water. You can also take a nice hot shower with plenty of steam or sit in a really steamy bathroom.
