Use a humidifier.
Running a humidifier in your home will add moisture to dry, heated air. The moist air will help keep your skin, mouth, and nose lubricated, and helps prevent those nasty static shocks. Your goal is to aim for a comfortable home humidity level of between 30% and 50%.
Place Bowls of Water on Registers
This is probably the most effective of these humidity-boosting tips. Place metal or ceramic bowls full of water on heat registers or radiators to push humidity into the air. You may be surprised by how much water is released during cold months when the furnace is going full tilt.
Adding bowls of water around a room works kind of like a humidifier, but at a slower speed. Place a few bowls of water around the perimeter of the room you want to humidify and leave them there to allow the moisture to evaporate into the air.
During the summer, the warmer air holds moisture but during the winter months cold dry outside air infiltrates the house and couple that with the fact that we heat our homes causing hot air to rise and the dry colder air to settle into the lower areas of your house. This is what causes the house to feel so dry.
Adding moisture to the air is as simple as placing a vessel of water on top of, or next to, a radiator or other air heating system. Leaving wet towels and clothes out to dry is another way to introduce moisture into the air.
While it may seem counterintuitive, it is actually helpful to open the windows and remove the stale, dry air from your house. Open windows during the daytime to let the fresh air in. It will help you breathe easy, and your skin won't feel that dry and itchy. Plus, it will also improve your home air quality.
With cold, dry air, these membranes lose much of their moisture. Breathing dry air can irritate respiratory ailments, and in some cases lead to asthma, bronchitis, the common cold, the flu and even nosebleeds.
Chapped lips and cracked skin on your hands are some of the most common signs. But you may have noticed some of the following signs too: Irritated sinus and nose bleeds can make it hard to breathe or sleep at night. If you wake up in the middle of the night coughing, it might be from dry indoor air.
Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.
Place Metal Bowls Over Your Air Vents
By placing a metal or ceramic bowl of your floor vent, the hot air coming out of your vent is pushing moisture into the air. This is an extremely effective way to make a DIY humidifier and add moisture to the air of your home.
Some people start coughing when they breathe very dry, heated air. This can be caused by environmental irritation or allergies. This type of cough may be more noticeable when you first turn on your furnace in the fall, because dust and other irritants that have collected over the summer are blown into the air.
The duration to run a humidifier varies, but typically, it's beneficial to run it for about 12 hours daily, usually overnight. Factors such as room size, current humidity levels, and personal health needs can influence the duration. Ensure the room's humidity stays between 30% and 50% to maintain a healthy environment.
Boiling water on the stove will instantly release moisture in the air. This is a low-cost way to add warmth and humidity to your home. Instead of heating water in a microwave for tea or hot cocoa, use a kettle on the stove instead.
Even a bowl or a vase full of water can be an alternative to a humidifier. Leave them out on a sunny windowsill, and the evaporating water will help add moisture to the air.
Hack a humidifier to fight the dehydration. Twitter user Aaron B suggests soaking a towel with water, wringing it tightly so that it's not dripping, then hanging it over an ironing board in front of your room's vent or heater.
Place containers of water on elevated surfaces to increase humidity in a room. One of the easiest ways to add moisture to the air is to place bowls or saucers of water on various surfaces around the house.
