If you find yourself breaking out after a particularly sweaty workout, rest assured it’s not unusual. Sweating — whether from hot weather or exercise — may contribute to a specific type of acne breakout commonly referred to as sweat pimples.

The combination of sweat, heat, and friction can lead to clogging of pores. Plus, sweat on your skin may keep acne-causing bacteria in place.

Acne breakouts from sweat are more likely to appear when sweat combines with pressure or friction from headbands, hats, clothing, or backpack straps. Medically speaking, this is known as acne mechanica.

Keep reading to learn how to treat and prevent sweat pimples, and how to tell the difference between sweat pimples and bumps caused by heat rash.

Sweat pimples should be treated like any acne breakout:

Gently wash (not scrub) the area twice a day.
Use non-comedogenic, non-acnegenic, oil-free products.
Resist touching or picking.
Use acne medication.
Wash clothing, sheets, or pillowcases that touch your acne-prone skin.

To prevent acne breakouts due to sweating:

Maintain your regular acne treatment routine of washing and medication.
After periods of heavy sweating, shower with antibacterial soap.
Wash your workout clothing regularly.
Avoid tight-fitting clothes and accessories.
When possible, seek cooler areas with lower humidity, particularly during the hottest part of the day.
If possible, take special care to avoid tight clothing or equipment that may be contributing to the breakout (e.g. a chinstrap causing chin acne breakouts).

Another thing to consider is that the bumps on your skin may be a symptom of heat rash, rather than an acne breakout.

Heat rashes are caused by excessive sweating, typically during hot, humid weather. When blocked sweat ducts trap perspiration under your skin, the result is heat rash.

Heat rash symptoms can look like pimples

The two most common types of heat rash, miliaria crystallina and miliaria rubra, can look very similar to acne. In fact, experts at the University of Pittsburgh describes heat rash as looking like “a cluster of red bumps that resemble pimples.”

Miliaria crystallina (sudamina) can appear as small white or clear, fluid-filled bumps on your skin’s surface.
Miliaria rubra (prickly heat) can appear as red bumps on your skin.

Typically, miliaria crystallina is not painful or itchy, while miliaria rubra can cause prickly or itchy sensations.

Heat rashes typically appear on the back, chest, and neck.

The treatment for mild heat rash is to remove yourself from exposure to excessive heat. Your rash will most likely clear once your skin is cool.

If the rash is severe, your doctor may recommend topical treatments, such as:

calamine lotion
anhydrous lanolin
topical steroids

To avoid heat rash, take steps before exposing yourself to situations that might result in heavy sweating. For example, don’t exercise outdoors during the hottest part of the day.

Or, in an especially hot, humid environment, try working out first thing in the morning, before the sun has had a chance to heat things up.

Additional suggestions include:

Wear soft, loose-fitting, lightweight cotton or moisture-wicking clothing when the weather is hot.
Seek shade or air-conditioning during hot weather.
When showering or bathing, use a soap that doesn’t dry your skin and cool water.
Allow your skin to air dry as opposed to using a towel.
Avoid using ointments that can block pores, such as those containing mineral oil or petroleum.
Make sure your sleeping area is well ventilated and cool.

Although excessive sweating can contribute to acne breakouts, your sweat pimples could also be a symptom of heat rash.

You might be able to address both conditions by cooling off and:

avoiding places and activities that increase sweating
washing — but not over-washing or scrubbing — your skin
using gentle antibacterial soaps and non-comedogenic products
cleaning your clothing, bedding, and other materials that come in contact with your skin
wearing loose-fitting, lightweight clothing when the weather is hot

MOSCOW, April 29 – RIA Novosti. Cold sweat combined with fever indicates the need to see a doctor, the therapist Lyudmila Lapa spoke about this in an interview with Zvezda. According to the physician, sweating can mean two things: intoxication or internal overheating. At the same time, sweat can be cold or hot, and each of these states means something different. “When the sweat is cold, you must definitely pay attention to the lungs, because it can be an inflammatory process or an exacerbation of some kind of chronic. You must immediately measure temperature and call a doctor, if any. This is a bad indicator,” Lapa warned. At the same time, the release of a large amount of cold sweat indicates hyperhidrosis, which indicates the active stage of a viral attack on the body, the specialist noted. In this case, you should also consult a doctor about further actions. “In general, this is a disease, of course, of the endocrine system, you need to pay attention to it. If the slightest tachycardia is disturbing, everyone goes to a cardiologist, and this is still more of an endocrinological problem. In fact In fact, this is a serious reason to see a doctor,” the physician concluded.

Excessive sweating of the face

Localization of sweating on the face is a rather rare phenomenon. However, this problem also has its own name – facial hyperhidrosis, it is also graniofacial hyperhidrosis, it is also the “sweaty face” syndrome. Even with small physical exertion or unrest, people with such a problem feel discomfort, sweat “flows in a stream”, standing out profusely on the skin of the face and head. The problem is exacerbated by the fact that it is almost impossible to mask excessive sweating of the face. Public professions, speaking, and sometimes even everyday communication become an almost impossible task for such patients. Election campaigners say that in the US presidential race, Richard Nixon lost to Kennedy in large part because large drops of sweat appeared on his face at rallies and during television debates, as a result of which voters considered it a sign of indecision and incompetence.

In its most severe form, facial hyperhidrosis can also lead to serious psychological problems – patients become withdrawn, avoid any social contacts, suffer from low self-esteem and even ridicule from others.

Facial hyperhidrosis occurs in people of all ages, even children. Therefore, the opinion is erroneous that the face turns red and sweats only in overweight, overweight elderly people.

Causes of facial sweating.

Excessive sweating of the face can be caused by increased activity of the sympathetic nervous system, which is responsible for activating the functioning of the internal organ systems. Often the problem is combined with palmar hyperhidrosis and the so-called blushing syndrome (appearance of red spots on the face, otherwise – generalized hyperemia of the face), as a result of which erythrophobia (fear of blushing) can develop. Also, when diagnosing this type of hyperidrosis, it is necessary to exclude the causes of hormonal genesis, allergic reactions to food or drugs, and dermatological problems. For example, eating spicy and fatty foods can cause facial sweating. In this case, this is not a cause for concern. But if this is repeated from time to time, if the profusion of sweating causes significant inconvenience, especially if you do not see serious reasons for this, then this is a reason to consult a doctor for a quality diagnosis. Severe sweating of the face can also become a symptom of any endocrine or infectious disease, allergies.

Treatment of facial hyperhidrosis.

Treatment of facial hyperhidrosis can take place in different ways, depending on the etiology of the disease – the correct diagnosis will help determine how to get rid of facial sweating in the most effective and gentle way.

1. Medical antiperspirants.

The least invasive procedures should be done first – the use of medical antiperspirants shows good results. The invention of antiperspirants opened a new era in the treatment of excessive sweating. These chemical compounds are based on aluminum chloride (aluminum chloride). It penetrates into the sweat tubules that come from the sweat gland and exit to the surface of the skin. A safe chemical compound is formed inside the tubules, which narrows their lumen. At the same time, perspiration is drastically reduced. Today, many manufacturers include in their product line products for sensitive skin that can be used, including on the face.

2. Injections of botulinum toxin type A.

Drugs such as Botox, Dysport also help to reduce facial sweating. This is a painless and quite effective procedure in cosmetology. In addition to smoothing wrinkles, botulinum toxin injections are also used in the treatment of hyperhidrosis in different parts of the body.
