Dry air (RH < 30) in the winter, is one the main causes of sinus infections and sore throats. Dry air can dry out the protective linings of the nose, throat and lungs, apparently causing increased susceptibility to colds & flue.
However in the ‘Wadi’ areas of Chaul, the RH is very naturally maintained between 45 to 65 percent due to the prescence of Areca Palms.

According to B. C. Wolverton, author of How To Grow Fresh Air, a six foot (1.8 m) areca palm transpires approximately 1 quart (1 litre) of water every 24 hours.
The air is humid and free from chemical toxins.
So it’s Never So Dry at Chaul, the Healing Heaven on Earth.
