Introduction
When the body heats up, raised itchy bumps may appear on the face and neck, possibly caused by miliaria (heat rash), eczema, urticaria (hives), or other conditions, requiring targeted treatment based on the specific cause. In addition to these relatively common causes, other possibilities include solar dermatitis, summer dermatitis, and folliculitis. If uncomfortable symptoms occur, prompt medical evaluation and timely treatment are recommended to avoid delaying diagnosis and management.
Itchy, raised bumps on the face and neck when the body heats up may be caused by miliaria (prickly heat), eczema, urticaria, or other conditions, and treatment should be targeted according to the specific cause. Detailed analysis is as follows:
1. Miliaria (Prickly Heat)
This condition is a common skin disorder in hot and humid environments, typically caused by blockage of sweat ducts. It may present as dense small rashes on the skin surface, sometimes accompanied by localized itching.
2. Eczema
Hot weather may lead to excessive sweating. If sweat is not wiped off promptly, it may trigger eczema. After skin irritation, symptoms such as erythema, papules, and vesicular papules may appear, often accompanied by itching.
3. Urticaria
Patients may develop urticaria due to temperature changes. When the face and neck are exposed to alternating cold and heat stimuli, skin itching may occur, and papules may appear upon scratching.
Besides the above relatively common causes, other possible conditions include solar dermatitis, summer dermatitis, folliculitis, etc. If any discomfort occurs, timely medical evaluation and treatment are recommended to avoid delaying the condition.
