Cold-weather practice rarely lands in the headline news. Heat does. But cold injures kids every winter in soccer, lacrosse, cross country, and youth football late seasons, and the protocol gets less attention than it should.
The temperature threshold. The National Athletic Trainers’ Association recommends practice modifications below 30°F and serious caution below 0°F wind chill. Below minus 18°F wind chill, frostbite on exposed skin can happen in about 30 minutes. Below minus 28°F, frostbite is possible in under 10 minutes. The National Weather Service publishes the wind-chill chart that runs the math.
Layering, not bundling. Kids run hot when they move and cold when they stop. The fix is layers a kid can shed during the active drill and re-add during the water break. Base layer wicks. Mid layer insulates. Outer layer breaks the wind. Cotton is the wrong base layer because it holds sweat against the skin and freezes.
The water rule still applies. Cold air dehydrates kids more than parents expect. Cold-weather sweat evaporates fast and you do not see it. The hydration plan does not change because it is January. 6 to 12 ounces every 15 to 20 minutes during practice, same as summer.
Hands, ears, and head. Frostbite goes after the extremities first. Gloves, a hat under the helmet, ear coverage when there is no helmet, and a neck gaiter when the wind is up. The kid who shows up in shorts and a hoodie because that is what the older kids wear is the kid who gets cold-injured first.
Asthma in cold air. Cold dry air narrows airways. A kid with exercise-induced asthma should pre-medicate per their plan and warm up longer than the rest of the team. The American Academy of Pediatrics’ Council on Sports Medicine and Fitness has guidance on this. If your kid struggles with the first 10 minutes of every cold practice, talk to the pediatrician about a pre-warm-up albuterol step.
The early signs to pull a kid. Shivering that does not stop after the kid layers up. Slurred speech. Confusion. Numb fingers or toes that do not warm back up after re-gloving. Skin that has gone waxy white or gray-yellow. Any of those, the kid is done for the day and indoors immediately.
The honest part. A 38°F practice with a 25 mph wind is harder on a kid than a 25°F still-air practice. Wind chill is the metric. Air temperature alone tells you maybe half the story.
What we want from a program in January: a posted cold-weather policy with wind-chill thresholds, a coach who carries a thermometer, and a willingness to move a practice indoors when the math gets bad.
