Red, blotchy rashes on the hands are uncomfortable and unsightly. They can be caused by a variety of conditions, from an allergic reaction to an immune system disorder. They may be easily treatable, as in the case of winter dry skin, or more complex, requiring a prescription of corticosteriods or oral or topical antibiotics.
Dry Skin
One possible cause of red blotchy patches on the hands is simple dry skin. According to the University of Iowa Hospitals and Clinics, exposure to soapy water, harsh chemicals and extreme temperatures are common causes of decreased levels of protective skin oils. It is possible for skin dried by the elements to develop dermatitis, which can become serious if not treated. Keeping your skin moisturized in very cold or very hot weather is essential for preventing the blotches associated with dryness.
Eczema
Eczema, also known as dermatitis, is thought to be a disorder of the immune system. Eczema leaves your skin feeling rough, dry and often very itchy. It can also alter skin pigmentation, leaving red blotches that later turn brown. If not properly treated, eczema leaves dry, cracked and broken skin open to infection. According to MayoClinic.com, the disorder may be accompanied by hay fever or asthma and usually appears in childhood, though adult-onset cases do occur. The most frequently affected areas are the arms, legs and hands.
Psoriasis
Skin affected by psoriasis rapidly builds up dry, dead cells that look like thick scales. Sometimes accompanied by arthritis, psoriasis is a chronic condition. Other symptoms plaguing psoriasis sufferers include stiff joints and thickened, ridged fingernails. Psoriasis outbreaks may occur for several weeks or months, then cease and return later. MayoClinic.com reports that psoriasis occurs when T lymphocyte cells, usually responsible for eradicating viruses in the body, attack healthy skin cells. Stress and certain medications, such as beta blockers and lithium, may exacerbate symptoms.
Dermatitis
Dermatitis is a general term for a rash caused by skin irritation. Contact dermatitis is caused by an irritant such as soap or chemicals. Atopic dermatitis is common in arid climates, while seborrheic dermatitis occurs on parts of the body rich in sebaceous, or oil-producing, glands. Lack of B vitamins or an excess of vitamin A can lead to symptoms of dermatitis.
Prevention/Solution
Taking brief, lukewarm showers instead of soaking in hot baths can keep your hands from becoming red and blotchy. Wear gloves when you clean or go outside in cold weather, making sure to apply moisturizer first. Drinking at least eight 8 oz. glasses of water each day helps keep your skin hydrated and can help prevent red, blotchy hands. If self care does not help, consult your doctor.
