Dryness, allergies, infections, stress, and diseases like diabetes, thyroid disorders, or liver problems can all lead to skin itching. Itching can also be made worse by using hot water, harsh soaps, or low humidity. See a doctor for blood testing and appropriate therapy if the itching is severe, ongoing, or not accompanied by a rash.

Hand cracks are frequently brought on by extremely dry skin, frequent washing, exposure to chemicals, or eczema. Wear gloves when performing damp tasks and apply a thick moisturizer or petroleum jelly multiple times a day, particularly after washing. See a doctor since you could require medicinal creams if the cracks are deep, bleeding, or not healing.
