polar vortex : round II

the return of chiberia and below zero temperatures in Chicago caused channel 5 to issue some recommendations about how to stay survive extremely cold temperatures :

wear mittens rather then gloves - this keeps the fingers together, warming the extremities

cover mouth to protect lungs - in low temperatures one can injure their respiratory tract by breathing very cold air

multiple loose fitting layers - trap air in layers close to your body

 

Additional personal recommendations include thick wool socks and a hat as well as well made boots. Also, urinating helps conserve your body's energy because it requires energy to heat the water in one's bladder.
