How it worksTheir design reduces the heat loss in a person's body which would otherwise occur due to thermal radiation, water evaporation, or convection. These blankets are included in many emergency, first aid, and survival kits because they are usually waterproof and windproof. In first aid the blankets are used to prevent/counter hypothermia. A threefold action facilitates this:
- The airtight foil reduces convection
- Heat loss caused by evaporation of perspiration is reduced
- To a limited extent the reflective surface inhibits losses caused by thermal radiation.
