When your skin feels itchy, often there is an apparent reason. Many times, the skin temporarily itches due to heat rash or an allergic reaction to an insect bite. In some cases, a medical cause may be the reason the skin is itchy. Below are three common causes of itchy skin, along with some smart ways to relieve the discomfort.
1. Heat Rash (Prickly Heat)
Heat rash (or prickly skin) often causes red bumps or a rash. These symptoms often occur when the weather is hot and humid and pores become blocked. Although heat rash is most common in babies and toddlers, adults are affected as well. Mild forms of prickly heat are characterized by the redness and itchiness alone, although in more severe cases, pus-filled blisters may occur.
To avoid heat rash when the weather is warm, wear loose fitting clothing that allows the skin to breathe. An application of calamine lotion or hydrocortisone cream may relieve the itch and inflammation. Some individuals also find relief from itchy heat rash by applying aloe gel to the affected area. Aloe is cooling and has anti-inflammatory properties.
A soak in a lukewarm oatmeal bath may also help relieve your itchy skin. Oatmeal is soothing for almost any type of itch.
2. Allergic Reaction (Skin Allergy)
An allergic reaction or skin allergy may cause bumps along the skin, along with a red appearance and an annoying itch. Your allergy may be caused by contact with the oils of a plant such as poison ivy, or as a reaction to an insect bite.
If your only symptom is itching and a localized rash, your symptoms may be easy to treat with home remedies. For an itch due to contact with poison ivy, oak, or sumac wash the area with lukewarm water and mild soap to remove the oils from your skin. You may then apply an anti-itch cream, witch hazel, or calamine lotion to relieve the uncomfortable itchiness.
Insect and spider bites can also cause skin allergies for individuals with sensitive skin. Whether bitten by a mosquito, spider, or another pest you may reduce the swelling and itch by using an ice pack on the affected area.
Taking an oral antihistamine may also help. Antihistamines inhibit the production of histamine due to allergens. Placing a cool compress on the area may also quell the itch.
You should avoid scratching your skin because doing so may cause an open sore that could be prone to infection.
3. Thyroid Disorder
Although you might not think of a thyroid disorder as a reason behind your itchy skin, a thyroid condition could be the cause. The thyroid is a gland that regulations various functions within your body. When the thyroid gland is not functioning properly, you may develop unpleasant symptoms, with skin itchiness being one of them.
You should see your healthcare provider for a definite diagnosis and advice for controlling this condition.
If you are suffering from a thyroid disorder, you have many options available to you to relieve your dry and itchy skin. Your dermatologist may recommend that you use a moisturizing lotion or cream to combat the dryness. You might also try applying some petroleum jelly to your skin as this helps seal in moisture. No matter which method you choose, once you have relieved the dryness, your itchy skin should subside.
Avoid taking long, hot showers or baths, as doing so may dry out your skin and cause further itchiness.
As a final note, if you develop a fever, chills, or pus-filled blisters over a wide area, see your doctor or dermatologist promptly.
