The whole body itchiness (pruritus) can be caused by many different factors, including dry skin, allergic reactions, insect or bug bites, skin conditions like eczema or psoriasis, infections, internal diseases (such as liver or kidney disease), pregnancy, medication side effects, or nervous system disorders. Itching can also result from environmental irritants like chemicals, soaps, or clothing materials. Sometimes it may be linked to more serious conditions like cancers or blood disorders, though often it is due to more common causes like dehydrated or inflamed skin. Identifying and treating the underlying cause is key to relief. Using moisturizers, avoiding allergens, or seeking medical advice if severe or persistent is recommended.
