Why does heat rash grow?
This is a typical heat rash, due to the high temperature and humidity in the environment, excessive sweating, not easy to evaporate, resulting in the closure of the sweat ducts, sweat can not be smoothly discharged, retention, and finally rupture due to increased internal pressure, the overflow of sweat infiltration and stimulation of the surrounding tissue inflammation, in the sweat holes appear papules, papules and small blisters. It is often said that prickly heat is the result of muffling, which is the reason.
Who is prone to heat rash?
Prickly heat is usually found in children, in the neck, chest and back, elbow fossa, popliteal fossa and other creases, children can occur in the head, forehead and other sweaty parts, especially like the above small babies, summer is already hot, plus the baby does not sweat well, and mothers worry about the cold blindly add clothes, prickly heat is more likely to occur.
Three tips to recognize heat rash: location + papules, papules + color
According to the damage of sweat ducts and sweat overflow site, clinically divided into the following types.
1.Crystal-shaped corn rash
As the name implies, it is a small crystal-like blister, also known as white prickly heat, caused by sweat overflowing in the stratum corneum or sweat ducts under the stratum corneum. It is common in patients with high fever and heavy sweating, prolonged bed rest, and excessive weakness.
2. Red corn rash
It is more common and can be a small papule or papular rash surrounded by a red halo, also known as red prickly heat, where the overflow of sweat occurs slightly deeper in the epidermis. The overflow of sweat occurs slightly deeper in the epidermis. A mild burning and itching sensation is felt.
3. Pustular prickly rash
Also known as pustular prickly heat. Mostly developed from red corn rash with a pinhead-sized pustule at the top.
4. Deep prickly rash
Also known as deep prickly heat, caused by sweat overflowing in the upper dermis, especially at the dermal-epidermal junction. It is common in patients with severe and recurrent red milia. The lesions are dense, skin-colored blisters that are clear and do not easily break down, increasing in size when sweating and decreasing in size when not sweating. When the rash is widespread, there may be compensatory sweating increase on the face, axillae, hands and feet, other sweat gland function is basically lost, the whole body skin sweating decrease or no sweating, can cause tropical sweat closed failure or heat exhaustion, the patient may appear weakness, sleepiness, dizziness, headache and other systemic symptoms.
The recognition of prickly heat is still quite high, and the common people can usually see it. However, sometimes, it still needs to be properly identified, such as summer dermatitis, which is also common in summer, but it has a distinct seasonality and usually appears as papules and papules on top of a large erythema with intense itching. In addition, prickly heat in infants can be easily confused with infantile eczema, the former being temporary while the latter is chronic and recurrent, often with yellow ooze after scratching, and can occur throughout the year, often recurring or worsening in the winter. In addition, eczema can occur in any area.
What should I do if prickly heat occurs?
Prickly heat is a common summer skin disease, especially in babies who have been “covered” for a long time, but once found, mothers do not need to panic, mainly local treatment. You can use a cool powder such as prickly heat powder, or a cool anti-itch lotion such as 1% peppermint glycopyrite lotion, 1% peppermint tincture; pus rash can be treated with 2% fish stone glycopyrite lotion, yellow lily puff powder. When itching is obvious, oral antihistamines can be taken, and antibiotics can be used for pustular prickly heat infection.
Here, we need to remind you that you can’t use prickly heat powder after the skin has ulcerated; don’t confuse adult and children’s prickly heat powder because adult prickly heat powder generally contains boric acid, while boric acid is prohibited in pediatric prickly heat powder. In addition, adult prickly heat powder and pediatric prickly heat powder contain different drugs and doses, children should buy prickly heat powder specifically for children. In addition, many parents respond that their children’s hands are always licked into their mouths after applying prickly heat powder, and their mothers are worried about the health effects on their children. Generally speaking, more than 99% of the ingredients of prickly heat powder are talcum powder, which is mild and safe, not toxic, so a small amount of intake will not have much effect. Parents can also try to gently apply a little on their hands when the child is sleeping. In addition, you can also put some edible dry powder such as corn starch on your hands instead of prickly heat powder, which can keep the area dry and will not affect your child’s health if he or she accidentally ingests it.
