Introduction
In general, itchy palms may be related to dry weather, insect bites, contact with irritants, eczema, or tinea manuum (fungal infection of the hands). If discomfort occurs, it is recommended to seek medical attention promptly and undergo general treatment or medication under a doctor's guidance. In daily life, one should maintain clean and dry hands, avoid direct contact with irritating substances, and refrain from prolonged exposure to damp environments.
Generally, itchy palms may be related to factors such as dry weather, insect bites, contact with irritants, eczema, or tinea manuum (fungal infection of the hands). If discomfort occurs, it is recommended to seek medical attention promptly. Specific causes are analyzed as follows:
1. Dry Weather
Dry air and low humidity during autumn and winter cause the skin's surface moisture to evaporate more quickly, leading to dry skin and resulting in itchiness on the palms. It is important to keep the skin moisturized by using moisturizing creams or lotions for proper hand care.
2. Insect Bites
If the palm is bitten by an insect, a localized inflammatory reaction may occur, causing symptoms such as redness, swelling, and itching. Applying an ice pack wrapped in a towel to the affected area for 10–20 minutes can help constrict local blood vessels and reduce itching and swelling.
3. Contact with Irritants
Frequent exposure to detergents, cleaning agents, or other irritating substances can damage the skin barrier, leading to itchy palms. Avoid direct contact with irritants by wearing protective gloves and wash hands promptly after exposure.
4. Eczema
Long-term exposure to hot, humid, and poorly ventilated environments may trigger eczema. Patients often have impaired skin barrier function, making the skin susceptible to various irritants, which can lead to itchy palms accompanied by symptoms such as swelling, peeling, and oozing. Treatment should be guided by a physician using topical medications such as mometasone furoate cream, halometasone cream, or fusidic acid cream.
5. Tinea Manuum (Hand Fungus)
Poor hand hygiene over time can promote fungal growth and infection, leading to tinea manuum. Fungal infections disrupt the normal skin structure and provoke local inflammation, causing symptoms such as itchy palms, blisters, and red patches. Treatment should follow medical advice and may include antifungal medications such as ketoconazole cream, clotrimazole cream, or itraconazole capsules.
In daily life, it is important to keep the hands clean and dry, avoid direct contact with irritants, and minimize prolonged exposure to damp environments.
