What causes Heat Rash on Face
Dee Anna Glaser, professor of Dermatology at Saint Louis University, School of Medicine in Missouri, explains the causes of Heat Rash on face as below.
Contact Rashes
Contact rashes are a localized allergic reaction of the skin, and are caused by direct contact with variety of substances. This is called contact dermatitis and causes local rash and inflammation only in the area contact where contact has been made. Common causes of contact dermatitis include:
- Rubber, Latex and elastic products
- Detergents, perfumes and cosmetics
- Chemicals in the environment or in clothing
- Certain plants such as poison ivy
- Metal such as zinc, nickel and silver
Prickly Heat is another form of contact rash that caused by wearing tight fitting clothing, or too many layers, which does not allow the skin to breathe. Sunburn or excessive use of artificial sunlamps or sun beds can also cause heat rash. Heat rash that occurs on flexural skin and aggravated by friction is called intertrigo.
Sun-induced Rashes
- Prickly heat known as miliaria develops when sweat glands in the skin get blocked. It may be aggravated by wearing tight fitting clothing, or too many layers, as this does not allow the skin to breathe.
- Sunburn or excessive use of artificial sunlamps or sun beds can also cause a type of heat rash.
- Polymorphic light eruption [PLE], is an immune response to increasing ultraviolet light [UV light exposure. It typically comes on in the spring or while on holiday in sunnier climates.
Allergic Rashes
Allergic rashes [urticaria or urticarial rashes] are caused by excess production of histamines in the body in response to something in your environment or something that you have eaten.
Sometimes these types of rashes occur without any known triggers. These rashes are often called hives, and can anywhere on the body and do not require direct contact with the skin. You may come out in an allergic rash in response to a wide variety of stimuli, including:
- Medication
- Insect or bee stings
- Infectious skin diseases
- Foods especially shellfish and nuts
- Infectious skin disease
Infectious skin Diseases
Several infectious skin diseases also cause a rash. These can be caused by a number of infections with bacteria or viruses, and infestations of mites within the skin. They can easily be passed on by direct contact, including;
- Impetigo
- Molluscum contagiosum
- Scabies
Some infectious skin diseases such as scabies are caused by mites that bore into the skin surface causing irritation and a localized rash. Most infectious skin diseases are common and relatively harmless. Many of them usually only occur in children.
Infectious diseases of the body
There are several diseases of the whole body that include a skin rash as one of their symptoms. These include:
- Shingles
- Meningitis
- Rubella
- Measles
- Chickenpox
Disease based rashes generally appear suddenly, without any obvious trigger, and are usually accompanied by other symptoms such as a fever, lethargy and flu-like symptoms. Rashes caused by infections can often be unbearably itchy.
Chronic Skin Diseases
There are two main chronic skin diseases that cause rashes- eczema and psoriasis. Inflamed rashes and scaly patches can appear anywhere on the body but most often occur around knees and elbows or in patches on the face. The symptoms of chronic skin diseases tend to come and go in flare ups, often in response to external stimuli.
Taking bed rest for too long
Taking prolonged bed rest can also be the reason behind the cause of heat rash. This may elevate to severe level if they are suffering from fever. It is recommended to keep yourself clean to get rid of heat rash.
Immature sweat ducts
Heat rash especially in babies is usually due to immature sweat ducts which get ruptured easily a factor that result to perspiration beneath the skin. Heat rash may also develop if the baby stays in an incubator in the first week after birth. Heat rash can also appear due to wearing of warm clothes or fever.
Physical activities
You can get heat rash due to intense exercises, hard work as well as activities which may cause sweat on the body. There are high chances of the sweaty body get rubbed which in turn causes heat rash.
Overheating
Just like hot and humid atmosphere, overheating may also cause the formation of heat rash on the skin. Dressing warm clothes, sleeping under an electric blanket can also cause the problem of heat rash.
How Long does heat Rash Last
Most cases of heat rash do not require any kind of medication. The rash begins to go away once the skin starts to cool down. Since heat rash is often a temporary condition, within 3 to 5 days, the skin is expected to be completely rash-free already. Most of the heat rashes heal on their own.
Heat Rash on Face Baby
Heat rash in babies is also known as summer rash and it is an eruption of little bumps and sometimes tiny blisters on the skin that shows up when your baby overheats. The bumps may appear red, especially on light skin. Children of all ages can get heat rash, but it’s most common in babies.
If your baby has heat rash, you’ll most likely see it in the folds of his skin and on the parts of his body where his clothing fits snugly, including his chest, stomach, neck, crotch, and buttocks. If he often wears a hat, the rash may spread across his scalp or forehead.
Heat rash develops when your baby sweats so much that her pores clog and sweat can’t get out. Babies and young children are especially prone to heat rash because they have smaller pores than adults. Hot, humid weather is prime time for heat rash, but you might see it in winter if your baby wears too many layers of clothing or running a fever.
Is heat rash serious when it comes to babies? The answer is no, but it’s a sign that your baby is too warm and overheating can lead to serious conditions such as heat exhaustions and heat stroke. Being too warm during sleep can also raise your baby’s risk of SIDS. The heat rash in babies can be painful as well as itchy, and can also be tender to the touch.
To prevent heat rash on baby face according to Dr. Jonathan Bowling, who is a consultant Dermatologist, and prolific health writer, you need to practice the following:
- On a scorching day, you need to keep you baby indoors in air-conditioned space, or look for cool shady or breezy places to sit and play outside. Make sure he is well hydrated by breastfeeding or formula-feeding often.
- Don’t use baby powders- not only can they cause breathing problems and irritate your baby’s lungs but they also block pores and make the skin warmer.
- If it is hot at night, use an air conditioner or a fan in your baby’s room. Direct the fan near the baby but not so that it blowing directly on her. Or place it far away so that only a gentle breeze reaches her.
- Pay attention to areas that tend to get moist, such as the neck, crotch and areas where folds of skin can trap sweat. Wash these areas with cool water and try to keep them as dry as possible.
