It’s essentially an infrared sauna — which uses infrared rays to heat the body directly — but in blanket form. So instead of having four walls and a bench for sitting, an infrared sauna blanket wraps around your body as if it’s a sleeping bag that plugs into a wall and heats up.
Other than those differences, the two — blanket and physical sauna — are pretty similar. As their names imply, both products use infrared light to heat the body directly, thereby warming you up but not the area around you. You can buy a far infrared sauna blanket in the UK online.
If you’re not a fan of heat and find it hard to breathe in rising temps, an infrared sauna blanket might not be worth trying. As for everyone else? If you’re okay with giving a new gadget backed by minimal research a try, then just proceed with caution, and be sure to follow the instructions.
Most blankets cost well over $100 and many are even closer to $500, so it is somewhat of an investment. And while again, it may help improve your health, science doesn’t say it’s a definite do-gooder. So, weigh the cost with what you’re looking to improve.
