WARNING: It's about to get scientific in this bish.
Our feet have a big impact on our body temperature and an even bigger impact on our sleep. That's because our feet have a large surface area and specialized blood vessels which can be opened up to pass high volumes of blood through them and therefore offload heat quickly when required. WOW.
This, coupled with the fact that the feet are at the end of our limbs and don't have much muscle (which produces heat) means that they cool down much more than other regions of the body.
And guess what...just putting on socks won't warm your feet up immediately. That's the beauty of the Bomfy B! The foot pocket keeps your feet and lower legs warmly wrapped up and protected from the cold in addition to just keeping them from popping out of the end of your blanket! But if you're like me and get warm very easily, you don't overheat because our blankets are an ultra plush, light material that doesn't smother your upper body, just keeps you perfectly snug!
