Cracking bleeding hand skin

[OakLeaf]

Depends on the cause, though - humidity triggers my dyshidrosis, and especially sudden increases in humidity like the beginning of summer. It could also spur growth of airborne molds and dust mites, which would stress the immune system and could make it worse. If you get a humidifier, either get one with a humidistat or just install a hygrometer and monitor the humidifier to keep indoor humidity between 50% and 60%. That's normally high enough to hydrate skin and mucous membranes but low enough that molds and dust mites won't go nuts.
