Chemical heating pads release heat energy with the help crystallization process. Sodium acetate in the liquid state is packed in the heat pad. A stainless steel disc present in the heating pad initiates the process. When we press that disc, it pushes the liquid so that temperature rises and sodium acetate is converted into a solid form. During this process it releases heat.
Microwavable heating pads work by placing them in the microwave to produce heat with moisture content. So, these pads are packed with materials to retain moisture content like wheat, rice, etc. generally this type of heating pad is homemade. They can be made by using a sock or towel.

Functioning of a heating pad- when a heating pad is placed on the body part that is to be treated, the heat from it is absorbed by that part. Consequently, this heat dilates the blood vessels, and blood flow is increased. So, when blood flows at a rapid speed it carries the required nutrients and oxygen to the affected part quickly. This process significantly contributes to the healing process.
Most importantly the heating pad should not be used at its high heat capacity. Because it may burn your skin. So, one needs to start at low heat and increase depending upon the application. However, it is advisable to use heating pads at a low level of heat.
We should not use an electric heating pad for too long regularly. It may cause severe health issues like high blood pressure, damage of inner muscles, and so on. Especially in pregnant women, its usage can affect the baby. According to a study which was held in 2006, due to overuse of electric blankets people have died too.
The time taken by a heating pad to heat up depends on the material used. Commonly, an electric pad charges in 5 to 15 minutes. If overheated, they can get damaged, and in some cases lead to fatality. So, it is also advisable not to overcharge them. However, chemical pads heat up very soon.
