Foil Blankets
If you’ve ever seen marathon runners at the end of the race, you might have noticed that many wrap themselves in foil blankets. These blankets are used to regulate body temperature, which usually drops dramatically once they stop running.
These blankets are also called space blankets, and not just because they look futuristic. Foil blankets evolved from a lightweight insulator developed by NASA to protect spacecrafts and astronauts from extreme dips in temperature, according to the Jet Propulsion Laboratory.
