If you have taken my classes or are in Jogalates, you know that I have a love/hate relationship with running in COLD weather. I normally only run if it is over 30 degrees; however, I might have to change that. I just read an article stating how running smartly in cold weather could increase your fat burn by 15%.
According to The Journal of Clinical Investigations, when your body feels cool it will stimulate “brown fat” to be burned to warm up. Our bodies have 2 types of body fat, brown and white/ yellow. Up until recently, it was thought that we only had brown fat as newborns. (It is also the kind of fat that hibernating mammals have.) The purpose of this fat is to generate heat for our bodies by activating the use of the white/yellow fats and sugar for energy. (Medical News Today) A word of caution though, shivering will not stimulate the brown fat, so you need to just be a bit chilly.
In Self magazine, they offered a few tips to achieve this while exercising outdoors. Trade in your hat for just a headband to cover your ears. Layer up starting with a sweat wicking base, then an insulating layer followed by a weatherproof layer. Use a covering for your mouth to prevent breathing in the cold air which can just induce shivers. And lastly, think of a sweet memory which can make you feel warmer. (According to Emotion.) I also think it is wise to make sure your toes and fingers are covered if you are going to be out in the freezing temperatures.
So for you fair weather runners, you may just want to layer up and join your friends!
