Mylar was designed by NASA and has a storied history of insulating astronauts from the Apollo Program and Skylab. Whereas traditional blankets try to keep as much warm air as close to you as possible, emergency mylar blankets work differently. Mylar is essentially a thin sheet of aluminum and plastic that traps radiant body heat. Half of our body heat is lost due to radiation, so retaining 90% is quite extraordinary. Do emergency blankets warm you up when you’re already cold? The same properties that make mylar ideal for weather prevention also make it less than ideal for resuscitation. Mylar is incredibly thin and intentionally lacks in the insulation department because of its lightweight design. If you are fearful that you’re on the course for hypothermia, a thermal blanket alone will not save you. Instead, use a dry, thick layer of insulated fabric underneath the emergency blanket to get the best of both worlds.
