SCRATCHING THE SURFACE
Get the ins and outs of itch. Learn about the types and causes, how to avoid it, and how to relieve it.
The simple truth is that all kinds of things can make you itch. From the zipper on your hoodie to a flying insect, there are all sorts of evil forces out there trying to get under your skin.
Some causes of itch are more serious than others — just ask one of the more than 31 million people in the US who suffer from eczema.1 Psoriasis and dry patches can also cause discomfort that manifests itself as rough, itchy skin.2
But for every cause of itch, there’s are several treatments. The first step is identifying the culprit (or culprits). Then comes making a change to alleviate the discomfort. Sometimes it’s as easy as switching detergents; and for those other times when preventative measures don’t work (dang mosquitoes!), there are over-the-counter solutions that can help relieve the itch.
AN OVERVIEW OF ITCH
As far as what you should include, the basic list is pretty long — but better safe than sorry. Check out this list published by the Red Cross, and consider printing out a copy when you put together your first aid kits. It contains all the things you’d expect, like bandages and antibiotic ointment, plus a few things you might not expect, like a hydrocortisone-based product like Cortizone-10®.1
In broad terms, itch is defined as “a tingling or irritation of the skin that makes you want to scratch the area.”3 When we think of itch, what comes to mind are things like mosquito bites, poison ivy, and detergent.But in order to understand itch (and help figure out how to stop scratching), we need to zoom out a little. The most common causes of itch can be loosely organized into these four types:2
Very dry skin
Itchy skin conditions
Allergic skin reactions
TYPES OF ITCH
To figure out what to do about itch, it helps to first identify the cause. Here’s a look at what to watch out for with some of the most common types of itch, and how to relieve them. Plus a few ideas on how to keep the itch from coming back.
VERY DRY SKIN
The medical term for dry skin is xerosis.4 Simply put, dry skin is skin that doesn’t have enough moisture to keep it feeling soft. In most cases, very dry skin can be relieved by applying moisturizer to the affected area, making sure to rub it in completely.The most common causes of dry skin include:
Climate. Dry, desert-like climates have less natural moisture in the air. This lack of humidity can increase the likelihood of dry skin for people who live in or visit these climates.4
Genetics. Skin conditions can be passed down from generation to generation.4 These include eczema and psoriasis, which will be discussed in the Itchy skin conditions section below.
Health conditions. Certain illnesses can cause dry, itchy skin. These include psoriasis, eczema, diabetes, and kidney disease.
Occupations. Healthcare providers and hairstylists are more likely to develop dry skin because they wash their hands frequently. People who work outside also have an increased risk.4
With mosquito bites, the cause is usually obvious and the itch tends to go away quickly.3 Our article on outdoor living has some helpful information on how to deal with mosquitoes. (Spoiler alert: Those citronella candles we’ve been using? Turns out they’re good at setting a festive mood but not so good at keeping bugs away.)Things get a little trickier (and ickier) when we start looking at bed bugs, lice, and mites. These nasty little buggers can live on your skin and cause long-lasting itch that’s very hard to control.3
Bed bugs. If you’re waking up in the morning with little red welts and fear it might be bed bugs, check with a dermatologist to help determine if that’s the case. To get rid of them, the Centers for Disease Control and Prevention (CDC) recommends using a professional pest control company that has experience treating bed bugs.5
Head lice. Despite what you may think (and the fact that even saying the word “lice” can make your head itch), having head lice does not mean you’re dirty. It’s typically transferred by close contact with someone who has lice. And while lice don’t carry disease,6 the itching can be really annoying. At-home treatments are effective, and there are also special barbershops that specialize in lice removal.
Mites. Mites can cause a skin condition called scabies, which can be very itchy indeed. Most cases are caused by skin-to-skin contact, or, less frequently, from infested items like bedding, clothes, and furniture. As with lice, a case of scabies doesn’t mean you’re unclean. A dermatologist can determine whether or not you have scabies, and prescribe a course of action.7
ITCHY SKIN CONDITIONS
Eczema. Researchers believe eczema is caused by a combination of genes and triggers. And while not much can be done about the genealogy, identifying what triggers eczema can help with both avoidance and treatment. The most common triggers are metals, cigarette smoke, soaps and cleaners, fragrances, fabrics, and antibacterial ointments.8
Psoriasis. Over 7.5 million US adults are affected by psoriasis. It’s caused by an overactive immune system that speeds up skin cell growth, causing skin cells to “pile up” on the surface of the skin. Early treatment is important, as, if left unchecked, a condition called psoriatic arthritis can develop, which can lead to permanent joint damage.9
Chicken pox. Most people get chicken pox when they’re young. And although there is a highly effective vaccine, there is still a chance that kids can contract the disease. Since it’s highly contagious, if you think your child has the chicken pox, keep them home. Then follow the advice of your doctor for the best course of action. This usually involves a combination of oatmeal baths, topical ointments, and non-aspirin pain relievers.10
ALLERGIC SKIN REACTIONS
Believe it or not, one of the most common substances that can cause an allergic reaction is nickel. Which, unfortunately, is found in everyday objects like cell phones, jewelry, eyeglass frames, zippers, and belt buckles.2 We can also develop allergic skin reactions to nail polish, fragrances, detergents, shampoos, and latex.2
The bad news is that it can be tough to pin down exactly what’s causing an allergic skin reaction. Consult with a dermatologist or allergist if you are having trouble identifying the source of a skin allergy.2
The better news is that there are lots of fragrance-free and sensitive-skin formulas out there. Sometimes a simple change like switching laundry detergents can stop your favorite shirt from itching.
