Many suffer from dry skin, particularly the lower legs, elbows, and forearms regions. Dry skin itches because it is easily irritated. When your skin feels rough, flaky and scaly, it can cause you intense itchiness distress.
Low humidity caused by winter heating and summer air conditioning are major contributors for your itchy dryness. Also, as you age, a natural reduction of oil gland production may worsen your already dry skin.
Anything that further dries your skin, such as of soaps, antiperspirants, perfumes, or hot baths, will make the problem worse, so make use of these products sparingly.
Dehydration, sun exposure, and stress may also play a role in your dry skin. Lifestyle adjustments to avoid these dry skin causes are simply keep something to drink handy during waking hours, limit your time in the sun, and mind your stress management.
Dry skin and itching can affect your sleep, cause irritability, or be a symptom of a disease. As an example, diabetes and kidney disease can be a cause for dry skin itching. And some medications have the side effect of causing or making itchiness worse.
Your cause of skin itch may be one or combination of these common factors.
For extremely dry and itchy skin, try lanolin. If nothing works, see a doctor.
