The Little-Known Relationship Between Sweat Sensitivity and Heat Rash
If you notice that your child has itchy skin when it's a hot day, or after spending some time outside, she might have sweat sensitivity and could also be suffering from heat rash -- so what can you do prevent and treat it?
Every time Emma brings her 5 year old child, Izzy, to play outdoors, she would notice that her daughter would start to get itchy skin and would vigorously scratch her forehead, neck and arms.
She would also find little red bumps appearing across her daughter’s forehead, or on other parts of her body.
“We noticed that Izzy would be fine if there’s air-con, but the minute we step outside, her skin will turn red and she will start breaking out in rashes and get itchy all over. We realised that the small bumps would also come up wherever she sweats the most, like her forehead, neck and back.”
If this sounds familiar to you, then your child just may have sweat sensitivity and also suffer from heat rash.
So what exactly causes this skin irritation and what can you do to help prevent and treat it?
Sweat aggravates sensitive skin
After participating in strenuous activities such as dancing, playing sports, or just staying outdoors under the hot sun for too long, your child will sweat to help moderate her body’s temperature.
As the sweat evaporates from her body, it will cool the surface of her skin — but sweat can also be the main culprit to your child’s skin irritations.
Chemistry Expert, Anne Marie Helmenstine, Ph.D. explains that sweat (or perspiration) is mainly made up of water, urea, lactate, minerals (such as sodium) and trace metals — and according to the National Eczema Asociation, the sodium found in sweat can dehydrate your little one’s skin and cause stinging or skin irritations.
Heat rash commonly affects children
Living in hot tropical weather can take a toll on your child’s skin as the humidity will cause her sweat glands to work overtime and in turn make her skin very dry.
You might notice tiny red or clear spots on different parts of your child’s body (usually on the back and bottom), which can be itchy, stinging or feel “prickly”, and the skin might turn red.
This is miliaria, otherwise known as heat rash or prickly heat, which is caused by a blockage of sweat ducts.
Dr Mark Koh Jean Aan, Head and Consultant, Paediatric Dermatology Service, KK Women’s and Children’s Hospital (KKH) explains that if sweat does not evaporate and remains trapped beneath the skin, this can cause inflammation and rashes to appear.
It can also be caused by excessive sweating, wearing thick clothes, or the usage of heavy creams that block the sweat ducts.
Although heat rash can affect anyone, it is more common in children and babies due to their immature sweat glands.
How can you prevent and treat it?
In this hot climate, it is important to let your child stay cool either by staying indoors and use a fan or air-conditioner to help circulate the air.
If you are outdoors then try to seek shade, keep out of direct sunlight and make sure your little one wears a wide-brimmed hat and loose, light-weight clothing.
Dr Koh also recommends to parents that a light moisturiser cream that is applied after a bath can protect your little one’s skin and help in the maturation of the skin barrier.
