In order to avoid a rash and itchy skin, you need to avoid the triggers that cause it. These may include food, drugs, or heat. In addition, you can take cool baths to soothe irritated skin. You can even add baking soda or oatmeal to your bath to reduce itching. A humidifier can help relieve dry skin. If you suffer from dry skin, you should also use a moisturizer.
Food allergies
In most cases, food allergies cause itchy skin because the immune system reacts incorrectly to food, chemicals, or additives. Itching, swelling, and redness are common symptoms of food allergies. Common food allergens include nuts, soy, wheat, and dairy products. Antihistamines are often prescribed to treat the symptoms.
Drug allergies
A serious allergic reaction to a drug should be treated immediately. Symptoms can range from blisters to peeling and can be life-threatening. Anaphylaxis is the most severe reaction, resulting in hives all over the body, breathing difficulties, and swelling in the mouth and throat. Symptoms usually appear one to two hours after the drug is taken, but they can also develop days or weeks later.
Heat rash
There is nothing serious about the rash caused by excessive heat, but it is uncomfortable. If you have it, you should cool off and avoid exposure to the heat for a couple of days. It usually clears up on its own. You should consult with your health care provider, however, if you aren't sure of its cause.
Pruritus
If you suffer from itchy skin caused by allergies, there are a number of things you can do to alleviate the condition. The first step is to avoid irritating triggers. These can be household items or foods.
Vitamin D deficiency
A variety of factors can cause itchy skin, including an allergy to Vitamin D or inadequate amounts of Vitamin D in your diet. In addition to itching, other factors can also cause itching, such as an allergic reaction to a new soap or detergent, or a reaction to vitamin D supplements that contain certain colors or additives.
