How to Use the Cold Prevention Layering Guide
This tool takes today's high and low temperature, calculates the daily swing, and gives you a layering strategy to help prevent catching a cold. It gives a quick answer whenever the morning-to-evening temperature gap has you unsure what to wear.
Layering Guidelines by Temperature Swing
A swing of 27°F or more calls for full layering, while 18-27°F suggests keeping a light jacket or cardigan on hand. A 9-18°F swing needs just one light outer layer, and under 9°F barely requires any adjustment.
