Summer rash, also known as prickly heat, heat rash, or wildfire rash, is very common and can be troublesome.
The medical term for heat or summer rash is miliaria. It occurs when sweat becomes trapped due to an obstruction in sweat glands in the deeper layers of skin.
Skin rashes can affect anyone across all age groups. It is mainly caused due to heat and affects people who sweat profusely. Though it is not a severe skin disease, yet it can cause irritation, itching, inflammation, redness and blisters-like lesions. Rashes commonly occur in the neck, chest, and pubic regions and cause discomfort in the affected area.
People who suffer from overweight or obesity, and those who sweat quickly are more prone to get prickly heat. Also, infants and children are more predisposed to it as their sweat glands are yet developing.
Types of Summer Rash
There are basically three types of summer rash or miliaria:
- Miliaria Crystalline: This is the most general form. It begins small, clear or white swellings or bumps packed with sweat to develop on the skin’s surface. The bumps count 1–2 millimetres across. It does not cause any itching or pain and is more prevalent in babies than adults.
- Miliaria Rubra: This type is more usually known as prickly heat, and it causes more prominent bulges, swelling, and a lack of sweat in the involved area. It happens in deeper layers of skin and is more troublesome. If the bumps swell with pus or discharge, the medical name becomes miliaria pustulosa.
- Miliaria Profunda: This is the least familiar type of heat rash. It develops in the deepest layer of skin, and it can reappear and become chronic. It induces comparatively large, sturdy, flesh-coloured bumps.
Causes of Summer Rash
Summer rash, heat rash, or miliaria, occurs when sweat gland ducts become clogged.
This may be due to:
- sweat glands yet developing, as in newborn babies
- a hot and humid environment
- a fever
- physical activity
- wearing synthetic fabrics close to the skin
- prolonged bed rest
- wearing a nonporous bandage
- the use of a few medications, particularly those that lessen sweating
- a few health conditions, such as toxic epidermal necrolysis
- radiation therapy
When to consult a doctor?
The summer rashes generally go away without any treatment. However, consult a healthcare provider if:
- the rashes stay for long or become more rigorous
- there are symptoms of an infection, such as clear blisters or pustular lesions
- there are flashes of heat exhaustion and impotence to sweat
- there are other signs, such as a fever
Many ailments cause rashes, which may seem to be similar to heat rash or summer rash. A doctor can discover the underlying condition.
Diagnosis of Summer Rash
Summer rashes are not usually critical, but if symptoms persist longer than several days or signs of inflammation appear, visit a healthcare provider.
They will review the rash, probably with the use of dermoscopy for a closer examination.
If required, they may also exercise a skin punch biopsy or operate imaging technology to distinguish the cause of the rash.
Skin changes are a typical sign of many conditions. Summer rash can relate to other health issues too, including:
- bacterial infections, such as impetigo
