A moisture pad includes a porous pad, for example a sponge, and a container divided into a water reservoir and a compartment for securely supporting the porous pad. The reservoir has a filling opening provided with a closure. The closure includes a flexible dome that can be pressed to pressurize the contents of the reservoir. One-way valves regulate the flow of fluids between the reservoir and the porous pad compartment. Optionally, a lid may be provided as a closure for the container to reduce evaporation of the water. As another option, a strap can be provided for the container to allow the moisture pad to be worn on a person's body.
