Preventing dry hair and dry skinWritten by Duncan under Humidifiers | No Comments
The answer to the ongoing battle of rehydrating dry hair and skin is to not let it dry out to start with. By using a humidifier at home during the winter and maintaining an indoor humidity level of between 40-60% your hair will feel more manageable, your skin will not dry out and you will be more resistant to colds, flu and viruses.
During the winter months when we turn on central heating and close the double-glazing, our sealed homes can dry out to less than 25% relative humidity. This is as dry as the Sahara Dessert. The warm inside air tries to regain its moisture balance and sucks water from any available source, including our skin, hair, eyes, nose and throat.
This results in dry, flaky skin, especially around our face and hands, hair becoming more brittle and susceptible to split ends, and our eyes becoming itchy, especially for contacts lens wearers.
Very worrying effects of a dry inside atmosphere are our nose and throat drying out, as this leaves us more susceptible to colds and viruses. The mucous membranes in our nose and throat are natural defences against airborne germs. Dry them out and we are left vulnerable.
Breathing in dry air makes the uptake of oxygen and its subsequent transfer to the blood system more difficult. Fatigue, tiredness and reduced concentration levels are symptoms of a reduced oxygen supply.
Opening the windows in winter will not humidify a room as the cold outside air cannot hold a lot of moisture and when it warms up inside it dries even further.
The answer is to use a humidifier that will put the water back into the atmosphere leaving skin, hair, eyes, nose and throat naturally hydrated.
A well maintained indoor humidity level helps suppress dust as it binds it and reduces its ability to become airborne. Dry room air causes dust to rise. This is made worse by the thermal currents created by radiators.
