“Both eczema and psoriasis can cause a rash — patches of red, raised, itchy skin — and they can appear in the same places of the body, such as the hands and scalp. Neither condition is contagious but both can lead to infections. An experienced dermatologist may be able to spot the differences, but to the untrained eye, it’s hard to tell.  More than 32 million Americans will have atopic dermatitis, a form of eczema, in their life. About 7.5 million Americans have psoriasis.  The biggest difference between eczema and psoriasis is the underlying causes.

If you have eczema, summer might not be your favorite season. Some people with eczema are sensitive to heat. In hot weather, overheating can cause perspiration, which can lead to skin flare.

However, for most psoriasis patients, abundant natural ultraviolet B (UVB) light from sunshine can be a blessing. UVB light can slow down the abnormal growth of skin cells. It is used as a medical treatment for psoriasis for some.

But remember, too much of a good thing can become damaging. If you go sunbathing without using sunscreen or are exposed to sunlight for too long, overexposure can trigger psoriasis symptoms. If you start to feel itchy or see red spots, get out of the sun!”.
