How can I treat summer dermatitis? What should I do if the itching is sometimes severe and interferes with my daily life or sleep?

Summer dermatitis should be treated with intensive daily care, taking care to maintain ventilation and heat dissipation.
Loose, sweat-absorbing and breathable clothing is advisable; timely bathing and cleaning of the skin can be done, and the skin can be kept dry with talcum powder etc. as appropriate.
Generally, topical application of glyburide lotion, glucocorticoid topical preparations (0.1% buthydrocortisone cream, 0.1% mometasone furoate cream, etc., once to twice daily;) etc. can be used on the rash.
wet compresses with saline or 3% boric acid solution may also be used when the redness and exudation are more severe.
Summer dermatitis can sometimes be accompanied by intense itching; it is important to avoid scratching and to take oral antihistamines such as epalmatine, cetirizine and loratadine when itching is severe.
