While sleeping in my bedroom at night especially during heating season the room is dry and I wake up with dry mouth and thirst during sleeping hours.
I do not have a humidifier to put humidity in the air. Do not feel like buying one either.
The other day I thought of an idea to put humidity in the room. I took a household pail yesterday and put about 4 inches of water in the bottom. Then took a small hand towel and moistened it in the water and draped it over a wooden rod which lays on the rim of the pail leaving the bottom of the towel in the water. The towel hanging in the water acts as a wick.
It has been there about 24 hours and the towel is still wet and the water in the pail looks like it has used about one pint or so of water.
I awoke about 4:30 am and did not have a dry mouth and thirst The air feels more humid and does not have that dry heat feel.
