Mold rashes on skin

Mold induced skin rashes

Breathing in mold spores causes a rather long list of unpleasant symptoms. One of these symptoms is an extremely itchy red rash that usually appears on the face, arms, torso or legs. Here we will help identify it, reveal how it forms and what can be done in terms of treatment.

What causes mold rashes on the skin?

When breathing in mold spores your immune system realizes it’s a potential threat and in retaliation tries to destroy it by flooding your body with antibodies. It is this protective measure (the release of antibodies) which causes the rash and not the mold spores directly themselves. Those who are most likely to exhibit these symptoms are people with weak immune systems and anyone who has a natural allergy to mold.

In some cases spores do not have to necessarily be breathed in to cause these symptoms. They can sometimes form by merely landing on the skin.

What does a mold rash look like?

Mold is most prevalent during the summer when humidity levels are at their highest yearly levels. What one should also keep in mind is that warm temperatures and even the sun itself can cause rashes. Not only that but there are many other causes such as insect bites, certain plants and even stress.

So how do you tell if you have heat or mold exposure rash?

Mold rashes will most of the time appear as small red bumpy dots and can appear just about anywhere on the body such as the face, arms, torso and legs. Heat rashes have a very similar appearance but will show up where sweat collects such as on the chest, groin area, waist, back and armpits. If exposed to mold spores then you will more than likely be showing other symptoms in addition to the rashes.

The possibility of skin infection

As mentioned, these rashes can be extremely itchy and the urge to scratch can be hard to resist. However, scratching can break the skin open which leaves the possibility of infection. If the affected area is warm to the touch, exhibits signs of bright redness or / and has a discharge then it’s likely to be infected. The best thing to do in this scenario is to consult your doctor for antibiotics.

What are the treatment methods?

The most important thing you can do is to remove yourself from the problem environment until the mold issue has been resolved. There is no need for any special medication either because the symptoms will disappear by itself within a day or two after you have stopped breathing in spores.

To alleviate the itching sensations do any of the following:


Wear loose fitting cotton clothing: Loose fitting cotton clothing will help reduce itching. Avoid tight fitting clothing and especially wool.


Anit-itch creams: The easiest and quickest way is to purchase an over the counter anti-itch cream. They work well and are cheap as well as easily accessible.


Apply ice to the rash: Place ice cubes in a bag or use a bag of frozen peas and apply it to the rash for short periods of time.


Apply aloe vera: Aloe vera works wonders on any type of rash. If you have access to the plant break off a leave and extract the gel. Apply it directly onto the rash. Alternatively, you can buy an aloe vera topical cream.


Apply apple cider vinegar: Not many people know this but apple cider vinegar has an incredibly soothing effect on the skin. Simply put some onto cotton and dab onto the affected area. Another method is by adding some to a lukewarm bath and soaking in it for 5 to 10 minutes.
