There is extremely low temperature in Chicago  threatening life in the city.

Here are some tips how to survive in this cold spell:

IF YOU NEED TO GO OUT, WEAR AS MUCH WARMER CLOTHES. FROSTBITE CAN START IN 5 MINUTES.

NorthShore University HealthSystem experts state that the most danger for health in such weather is frostbite as it could freeze body fluids and cause tissue damage.

YOU CAN CALL IF YOU NEED TO HELP  HOMELESS PEOPLE

You should call 311 if you see anyone needs help, especially people without a shelter, says executive director for the Chicago Coalition for the Homeless, Doug Schenkelberg.

TAKE MEASURES TO KEEP YOUR HOME WARM ENOUGH

Lou Manfredini, who gives home improvement advice on WGN Radio each Saturday, suggest to take steps to protect home from low temperature. 
Checking furnace filters in homes and replacing them, locking windows and moving furniture away from vents can immediately improve the temperature.

PROTECT YOUR CARS AS WELL

Cars need to be cared in cold as well as humans do. So fill you fluids, fill your antifreeze, check your wipers and tire pressure before using your vehicle.
