A portable body warming device is disclosed having a housing which encloses separately a water compartment and a salt compartment. The salt compartment has segmented chambers, each of which contains salt which reacts exothermically with water supplied by means of interconnecting tubes. Addition of the water to the salt is controlled such that the exothermic reaction is effected over a period of time and usefully serves to warm the body of a user. For use in emergency water immersion situations, an automatic double starting valve is disclosed.
