How to Prevent Heat Rash During the Summer Months?

Summers bring that much needed heat from the chilly cold weather. As much as love that summer sun gently falling on your skin, there is an uninvited guest that comes along with summers. Summers may not be intense in the initial days, but as the season progresses it can lead to severe heat which when exposed causes heat rashes on the skin and other skin disease in summer season.

What is a heat rash?

Heat rash, also known as prickly heat rash or miliaria, is a common skin condition caused by blocked sweat glands. When sweat can’t evaporate properly due to hot and humid weather, or because clothing traps sweat against the skin, it gets trapped beneath the surface. This trapped sweat irritates the sweat glands, leading to tiny red bumps and blisters. Heat rash is most common in infants and young children, but it can affect people of all ages. Areas where clothing rubs against the skin, such as the neck, chest, back, groin, and inner thighs, are particularly vulnerable. 

What are the symptoms of heat rash?

Heat rash typically appears within a few hours of exposure to hot and humid conditions. Here are some common symptoms:

• Small, red or bumps or blisters
• Prickling or itchy sensation
• Mild burning or stinging

Skin rash in summer season is usually harmless and clears up on its own within a few days with proper care. However, if you experience the following, it’s best to consult a doctor:

• Fever 
• Pus-filled blisters
• Worsening symptoms despite home care

What are the three major types of heat rash?

The major types of heat rashes usually found are:

Miliaria crystallina: 

This type of rash is the mildest. It occurs when the pores, or sweat ducts, on the surface of your skin become clogged. Usually it appears as fluid-filled, transparent lumps. The lumps are brittle. 

Miliaria rubra:

Because it can result in small, inflammatory bumps on your skin as well as an itchy or prickly sensation, this type of heat is frequently referred to as “prickly heat”. The condition your doctor will refer to as miliaria pustulosa is when the bumps fill with pus. 

Miliaria profunda: 

This kind targets the deepest layer of the skin. This kind of heat rash has firm, painful, or itchy bumps that resemble goosebumps. They might crack and be exposed. 

What might be the possible reasons for developing a heat rash?

Heat rash is generally caused when the sweat-transporting ducts that present under the skin get clogged or blocked. It can cause skin irritation from sweat as it cannot pass sweat through its pores. A rash then appears. 

The rash’s most frequent cause is:

• When the sweat buildup between your clothing and skin
• Undergoing through hormonal changes
• When hair follicles block your sweat glands
• When there is no air flow between your clothes and skin

Consult the skin specialist hospital in Coimbatore, if you are noticing any heat rashes that are spreading and are causing severe itch.

While sunscreen is crucial for sun protection. Thick ointments can trap heat, it is important to choose lightweight sunscreens.
