The Different Types Of Eczema

HOW TO TREAT HEAT RASH & ECZEMA /SUMMER CARE FOR BABIES AND KIDS

There are actually many different kinds of eczema. In fact, experts tend to group them into seven specific types.

The most common is called atopic dermatitis. It affects more than 26 million people in the United States. Atopic dermatitis tends to develop in the first 6 months of life, but it can also develop later.

Atopic dermatitis is characterized by dry, itchy skin. The color of the rash tends to be:

  • reddish in people with lighter skin tones
  • brown or gray in people with darker skin

Sometimes your skin will get thicker in patches where the rash appears. It has a genetic component, but your immune system and environmental triggers may also play a role.

According to the National Eczema Association, the other six types of eczema include:

Its important to note that different kinds of eczema can overlap. In other words, you could have more than one kind at the same time. And they may require different treatment or management strategies.

Once you know what type of skin condition youre dealing with, you can take steps to treat it appropriately.

How Can People Protect Their Health When Temperatures Are Extremely High

The body can adapt very well in hot weather, but it takes time to acclimate. The actual temperature is just one factor when a person decides to work, play, or exercise in the heat. The heat index adds humidity to the equation since sweat cannot evaporate if the water content in the air is high. If the air holds as much water as it can there is no place for sweat to go, and evaporation cannot cool the body.

To minimize the risk of heat-related illnesses, try to avoid working or exercising in extreme heat. Avoid dehydration and other complications by taking frequent breaks to get out of the heat, and drinking plenty of water or other fluids to replenish fluid lost through sweat.

Early signs of heat-related illnesses include lightheadedness, weakness, and nausea. It is important to get out of the heat, cool off, and rehydrate immediately to avoid severe heat-related problems such as heat exhaustion and heat stroke.

Heat rash appears as very small spots. On children with lighter skin, the spots might look red. On children with darker skin, the spots might look brown, purple or grey. Heat rash can also look like very small, clear blisters.

There might be only a few spots or blisters, or they might cover a large area of the body. They most commonly appear over the face and neck. They often appear in skin folds too, especially in the nappy area.

Heat rash is often very itchy.

The blisters can get infected with bacteria. If this happens, the blisters might fill with yellow or white pus. Your child might have a fever and increased sweating over their body.

Abnormal Reaction To Heat In Eczema Patients

A 1998 study published in a German medical journal of dermatology investigated the differences in response to heat between eczema patients and healthy subjects. The researchers found out that the skin reacts differently to heat when it is affected by eczema.

For the study, the researchers recruited 21 patients with atopic eczema and 23 healthy controls.

For each of these study participants, they exposed the skin of the forearm on one arm to a cold bath and later to a warm bath for 15 minutes each. Then, the researchers noted the skin temperature of the other arm for each exposure.

The results of the study showed that eczema patients had a rather rigid and different reaction to temperature than normal subjects.

The researchers, therefore, concluded that atopic eczema may cause abnormal thermoregulation in the skin.

The result of this study is significant because it indicates that patients with atopic eczema may not be able to regulate their skin temperatures well enough. Therefore, hot temperatures may cause more skin damage in these patients because the body does not compensate for the heat with some cooling countermeasures.

Such impaired thermoregulation in eczema may be responsible for the itching, redness, rashes and local inflammation triggered in the skin by high temperatures.

How Is Heat Rash Treated

Heat rash normally goes away without treatment. However, there are medicines available from a pharmacy to ease the symptoms of itching. These include calamine lotion and antihistamine medicines. Your pharmacist may recommend a low-strength hydrocortisone cream, which is a type of steroid cream used to treat inflammation.

Speak to your pharmacist for further advice and to make sure any medicines you take are suitable for you.

You many need antibiotics if the area becomes infected.

If youre experiencing heat rash, here are some things that may help:

  • Cool down to avoid sweating. Try to avoid heat and humidity stay in air conditioning or near a fan, and make sure there is good ventilation.
  • Keep the skin dry.
  • Try to wear loose cotton clothing which can help prevent you overheating and making the itch worse. Avoid fabrics which irritate your skin, like wool or scratchy fabrics.
  • A cool bath or shower may help provide short-term relief from any itching, but excessive showering or bathing should be avoided as this can reduce the natural oils that protect the skin and may make it worse.

Swimming Rashes And Itches

Swimmers itch or cercarial dermatitis is an itchy rash caused by tiny worms called schistosomes. These parasites are becoming increasingly common in freshwater lakes and ponds throughout Europe and the UK. Theyre particularly prominent where there are water birds and mammals. You are more likely to encounter them in warm, shallow water which makes children particularly susceptible.

The rash resembles reddish pimples or blisters and can appear within minutes, or days, after swimming or paddling in infested water. Areas covered by swimsuits or waders will not be affected, but symptoms tend to worsen after each exposure.

Avoid swimming in areas known to be affected, and minimise the risk by rinsing and drying exposed skin immediately after leaving the water. Use a waterproof sunscreen, as there are reports that this provides some protection from the parasites.

Swimmers itch usually clears in a couple of days. But in the meantime, apply cool compresses, soak in a bath of Epsom salt or baking soda, and use an over-the-counter corticosteroid cream if necessary. See your doctor if the rash persists for more than 3 days, or if there is any sign of pus, as this could indicate an infection.

Taming The Immune Response

How To Treat and Prevent Heat Rash | Rachael’s Dermatologist Dr. Anne Chapas

Prescription skin meds that calm an overactive immune system can treat eczema from atopic dermatitis. Doctors generally prescribe them only for short-term use in people whoâve tried other treatments that havenât helped. They have a “black box” warning due to a higher cancer risk. So ask your doctor about the pros and cons. A biologic medication called Dupixent, given as a shot, works on the immune system to treat atopic dermatitis.

Baby Heat Rash Pictures

It can vary a bit child to child. Generally, heat rash in babies is a lot of small red bumps. They can be on the face, abdomen, in skin folds and the diaper area.

Depending on the clothing worn, you may see a correlation with more bumps where the clothing might be more restrictive. Waist bands, armpit areas, diaper line, etc., as its easier for their immature sweat glands to become clogged while compressed.

This is just one example of how heat rash can look:

With heat rash in babies who are younger, the bumps may be tinier, redder or more spread out. How it looks can also depend on how long baby was subjected to the heat which caused sweating. In infants with eczema or other skin conditions heat rash can also look different as more than one skin condition can be present at the same time.

Skip Scalding Baths And Showers

While itâs always best to work with your dermatologist on an eczema treatment plan, every treatment plan involves taking action at home, as well. You may need to change up your routine a little bit or forego things that you once enjoyed, like hot showers or baths, but these actions will likely help relieve your eczema symptoms. While a steaming hot shower might feel nice after a long day, itâs not going to help your eczema at all. In fact, the hot water stripping away your skinâs natural oils is likely only going to make your eczema symptoms worse. If you soak for too long in water thatâs too hot, youâre going to exacerbate your skin condition. When youâre experiencing a flare up, keep your showers a few degrees cooler and try to get in and out as fast as possible!

Treatment For Heat Rash Or Prickly Heat

You can usually treat heat rash or prickly heat at home by making sure your child stays cool and dry and avoids getting sweaty. This might include:

  • using air-conditioning if you live in a hot climate
  • dressing your child in light cotton clothing
  • avoiding too many layers when you dress your child or wrap your baby
  • removing sweaty clothing or wet nappies regularly
  • ensuring bedrooms are cool and ventilated
  • drying your babys skin folds after each bath.

To help your child with itchiness, you can give them a bath in lukewarm water. Its best to avoid soap, because this can irritate your childs skin. Use a soap-free wash or a simple moisturising bath oil if needed.

Pressing a cool damp cloth onto the affected area might also help your child feel more comfortable.

If your child is scratching a lot, speak to your GP, pharmacist or child and family health nurse about creams that might help. These might include calamine lotion or corticosteroid cream. If you can minimise your childs scratching, you can reduce the risk of your child getting a bacterial infection that spreads from one spot to another. The rash should disappear in 2-3 days, but it can take longer than this.

Could It Be Shingles

6 types of eczema: Symptoms and causes

If youre an older adult and experiencing a blistery rash, the most likely answer is that youve got shingles, a.k.a. herpes zoster, which affects one in three people in their lifetime, according to the CDC. Shingles is whats known as a reactivation virus that usually affects older adults, says Dr. Jones Lopez. Basically, once youve had chickenpox, the varicella zoster virus stays in your body. After the initial infection, the virus goes into dormant state for potentially decades, he says. Much later in life, when your immunity goes down, it can reactivate as shingles.

Unlike a chickenpox rash, the shingles rash is usually confined to a specific area of the body and appears in a single band, rather than spreading indiscriminately. It typically happens somewhere on the chest or back, says Dr. Jones-Lopez, although the head and other parts of the body can sometimes be affected. The key thing that distinguishes the shingles rash is that it doesnt cross the midline. If it spreads across your body, its not shingles. For example, if youve got a rash on left side of your face but another on the right side of your back, you can probably rule out this illness.

In addition to a rash , you may have some pain, itching, or tingling on your skin. You may also have flu-like symptoms . Like chickenpox, shingles rashes may itchbut they are mostly known for causing pain.

What Are The Causes Of Heat Rash

    It is uncertain why some people get heat rashes and others don’t.

    The sweat gland ducts can become blocked if excessive sweating occurs, and that sweat is not allowed to evaporate from a specific area. Some examples of how blockage may occur include the following:

    • Creases in the skin like the neck, armpit, or groin have skin touching adjacent skin, which makes it difficult for air to circulate, and prevents sweat evaporation.
    • Tight clothing that prevents sweat evaporation.
    • Bundling up in heavy clothing or sheets. This may occur when a person tries to keep warm in wintertime or when chilled because of an illness with fever.
    • Heavy creams or lotions can clog sweat ducts.

    Babies have immature sweat glands that aren’t able to efficiently remove the sweat they produce. They can develop heat rash if they are exposed to warm weather, are overdressed, excessively bundled, or have a fever.

    Heat rash may occur as a side effect of some medications .

    Eczema Coping Tips Diet

    In most cases, eczema isnt caused or made worse by diet. If you notice that your eczema seems to get worse after eating a particular food, you may be an exception to this. See your doctor or dietitian for proper allergy testing and dietary advice.Never self-diagnose or you risk depriving yourself of enjoyable and nutritious foods for no good reason. Unnecessarily avoiding certain foods can lead to nutritional deficiencies.

    Eczema In Hot Humid Weather

    For some people with eczema, warm, sunny, and humid weather brings relief. Others find that the hot weather triggers prickly heat and a frenzy of scratching. To ease symptoms, try these tips:

    Donât get too sweaty. Sweating dries out your skin, and the salt in sweat can sting and irritate it. So try to stay cool. Take it easy on hot days and stick to indoor activities. Use air conditioning or a fan if you need one.

    Wear soft, breathable clothing. Keep your skin cool by staying away from nylon, wool, rough linen, or any fabric thatâs stiff or itchy. Generally, cotton is best.

    Know how the sun affects you. Sunlight can be a salve for eczema. In fact, people with severe cases can benefit from ultraviolet ray treatments. But others find that sunlight is a trigger. If youâre one of them, shield yourself with clothes and a hat.

    Prepare before you swim. Chlorine in pools or the salt in seawater can be irritating for some people with eczema. Apply a layer of lotion before you dive in to see if it helps.

    Rinse off possible triggers. Take a quick, cool shower to soothe your skin and wash away sweat, chlorine, salt water, pollen, or other triggers. Gently pat yourself dry and apply lotion right away.

    Watch the sprays and lotions. Sunscreens and bug sprays can have chemicals that trigger symptoms. Opt for sunscreens that physically block the ultraviolet rays with the minerals zinc oxide or titanium dioxide. Test a sample on your arm before you slather it all over your body.

    What Does A Heat Rash Look Like

    How to avoid and treat Summer Rashes and Stings? – Dr. Rajdeep Mysore

    A heat rash may look like tiny bumps surrounded by red skin. Some forms of heat rash can be itchy or cause a prickly sensation, but its typically not painful.

    In infants, the rash usually develops on the neck, armpits, elbow creases and groin. In older children, it can also occur on the chest and back. The rash doesnt typically involve the eyes, nose, mouth, palms or soles.

    If your child develops the rash, you can expect that he or she will act normally, says Dr. Sabella. A child with a heat rash should not have fever or other signs of illness.

    These factors can contribute to heat rash:

    • Hot, humid weather or environment.
    • Physical activity, intense exercise, hard work or activity.
    • Fabrics that do not allow sweat to evaporate from the skin.
    • Overdressing a child or dressing in too heavy of fabric for the weather.
    • Sleeping under too many blankets.
    • Use of oils, thick creams or ointments, which can block the sweat ducts.
    • Immature sweat ducts, such as in a newborn.
    • Prescription medications that increase sweat gland function.

    Change Out Of Wet Clothing As Soon As You Can

    Staying dry should be your summertime mantra if youre struggling with eczema-prone skin. If you feel perspiration start to build and your T-shirt start to stick to your back, for instance, swap your wet clothes for dry ones as soon as you can. The BioMed Research International study found that changing clothes when they become wet with sweat is an effective way to manage sweat if you have eczema.

    Heat Stroke And Heat Exhaustion

    Heat rash may also be an early warning of heat stroke and heat exhaustion.

    Call triple zero immediately if you get symptoms of heat stroke such as a sudden rise in body temperature, red, hot dry skin , dry swollen tongue, rapid pulse, rapid shallow breathing, intense thirst, headache, nausea and vomiting, dizziness, confusion, poor coordination or slurred speech, aggressive or bizarre behaviour, loss of consciousness, seizures or coma.
