What causes small red spots on the body after staying in a hotel, and what should be done?

Small red spots appearing on the body after staying at a hotel may be caused by dry skin, environmental irritation, contact dermatitis, insect bite dermatitis, or folliculitis. If symptoms persist or worsen, it is recommended to seek timely medical attention at a正规 hospital. Specific analysis is as follows:

1. Dry Skin

Dry indoor environments in hotels can cause rapid moisture loss from the skin and damage to the stratum corneum, leading to small red spots. Apply a gentle moisturizing lotion promptly to replenish skin moisture, drink plenty of water, and avoid frequent hot showers.

2. Environmental Irritation

Residual disinfectants, dust, or other irritants in hotel rooms may trigger small red spots on the skin. Immediately change into clean clothes, wash the skin with lukewarm water, leave the irritating environment, and keep the skin well-ventilated.

3. Contact Dermatitis

Allergic reactions may occur when coming into contact with unclean bed sheets, towels, or other allergens in hotels. Avoid the allergen immediately. Take oral antihistamines such as levocetirizine hydrochloride tablets, ebastine tablets, or loratadine tablets as directed by a physician, and use calamine lotion topically.

4. Insect Bite Dermatitis

Red spots accompanied by itching may result from insect bites during a hotel stay, where insect saliva triggers a skin reaction. Avoid scratching. Topical treatments include mometasone furoate cream, hydrocortisone butyrate cream, or desonide cream. Apply cold compresses if itching is severe.

5. Folliculitis

Poor hygiene in hotels may lead to bacterial infection of hair follicles, causing inflammation. Maintain skin cleanliness and apply topical antibiotics such as mupirocin ointment, fusidic acid cream, or erythromycin ointment as prescribed. Do not squeeze affected areas.

In daily life, consider bringing your own bed linens and towels when staying at hotels; choose accommodations with good hygiene standards; maintain skin hydration to strengthen the skin barrier; and promptly remove yourself from potentially harmful environments and cleanse the skin if discomfort occurs.
