A sponge bath is a method of cleaning the body using a damp sponge or cloth instead of a full immersion in water. This technique is often used for individuals who are unable to take a regular bath or shower, such as the elderly, sick, or disabled. It helps maintain hygiene and comfort without the need for a bathtub. During a sponge bath, warm water is typically used along with mild soap. The caregiver gently wipes the person's body, focusing on areas that tend to accumulate dirt and sweat. This method is also useful for infants and young children, ensuring they stay clean and refreshed.
