Keeping Cool with Air-Con and Staying Moist with Humidifer


Heat and perspiration is the most common trigger of eczema and that’s exactly what gets my baby Marcie scratching. To keep the room cool, especially when it’s summer all year round in Singapore, you would have to on the air-conditioner. However, that makes the air dry and from experience, I realized that a humidifier did help my baby to sleep better. Here’s various pros and cons of a humidifier.


Helps combat dry skin, caused by air-conditioning. Dry skin is prone to irritation and lead to scratching. Doctor Claudia Aguirre commented in 2012’s twitterverse 1st Eczema twitter party hosted on this blog that should the humidity falls below 40%, moisture will start to strip away from skin, for full twitter party transcript see here.


Dust mites thrive in humid environments, so if your child is tested to be allergic to dust mite, you would need to find the right level of humidity to get the air moist, without encouraging dust mite to thrive (usually 30% to 50% humidity)

Too humid environment encourages growth of mold, which may be a possible trigger of eczema

And as I always emphasize, it is important to have your child tested to know what triggers the eczema. You can check out my Top 10 Eczema Tips and posts on Skin Prick Test and Itch Triggers.

There is a chance then for us to stop the allergic march in our children, where eczema is replaced by asthma and rhinitis.

  4. During a talk by Prof Hugo Van Bever at sneezywheezy’s play group on Aug 24th, he mentioned that cool air makes the dust in the room ‘lighter’ and to some extent, increase the likelihood that people with allergy to dust mite will sneeze etc. So, remember to keep the dust to a low level by having a thin mattress and light curtains.
