Winter Workout Tips to Avoid Frostbite & Hypothermia

Welcome back to Volume 2 of the 2023 Sports + Sweating Playbook, brought to you by the champions sweating it out at the International Hyperhidrosis Society. In this second volume, we're sharing tips on how to winterize your sweat-inducing outdoor workout or activities to avoid potentially life-threatening cold-weather injuries. 

The benefits of outdoor winter exercise hold true for all of us, regardless of our sweating. In fact, according to the Centers for Disease Control and Prevention (CDC), exercise:

  • Reduces anxiety
  • Reduces risk of depression
  • Improves sleep
  • Lowers certain cancer risks
  • Strengthens bones and muscles
  • Helps your brain
  • And so much more! 

Exercising outdoors in the cold takes preparation, no matter how much you sweat. But if you have hyperhidrosis or you just plain sweat when exercising outdoors, you need to be extra careful when it comes to winter health concerns like frostbite and hypothermia.  We’ve got the info you need so that you can hit the chilly slopes or trails and pound the pavement comfortably, safely, and enjoyably.

Key Points:

  1. If you sweat excessively in the winter, you are not alone. Research shows that the seriousness of hyperhidrosis is not necessarily dictated by the season.  In fact, the results of an extensive prevalence study conducted by the International Hyperhidrosis Society and involving members of our hyperhidrosis community (like you!) indicate that 65% of those surveyed reported that their sweating bothers them equally throughout the year.
  2. Sweating in the cold is not just a comfort or cosmetic issue. It’s a health and safety issue. You need to exercise to stay healthy, but you also need to keep warm and safe while doing it. 

Cold-Related Injuries That Should Not be Overlooked

Frostbite and hypothermia are serious winter health concerns associated with exposure to extremely cold temperatures for a prolonged period of time.  Frostbite is an injury that occurs when the skin and underlying tissue below the skin freeze, and most often impacts the extremities (such as:  ears, nose, cheeks, chin, fingers, and toes).  

And, when sweat is involved, clothing can become damp and speed up the loss of body heat. This can put you at risk for hypothermia, a potentially life-threatening medical emergency. Backpacker magazine warns that hypothermia can be deadly even at 50°F if you’re wet. That’s right, it doesn’t actually have to be really cold out for hypothermia to strike. 

❗Hypothermia can occur if a person simply becomes chilled from sweat, says the CDC.

❗Body heat is pulled from wet skin 25 times faster than from dry skin, notes the AMC

According to the CDC, the signs and symptoms of frostbite and hypothermia are:

  • Frostbite:  redness or pain in any skin area, white or grayish-yellow skin, skin that feels unusually firm or waxy, and numbness 
  • Hypothermia:  shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness

If frostbite or hypothermia is suspected, be sure to seek medical attention right away.  In the meantime, get into a warm room or shelter and remove any wet clothing then proceed to layer on warm and dry blankets or clothing.

Prevent Frostbite and Hypothermia  

To prevent frostbite and hypothermia while powering through your cold-weather workout or enjoying fun winter activities, we’ve compiled these tips to keep you safe from serious cold-weather injuries:

  • To retain heat that can be lost through the head, wear a warm hat.  Another option is a running beanie made from different materials to fit your need or environment.  Think merino wool, fleece, or a moisture-wicking material.  Some headwear even comes with a detachable face mask to further protect the face from frigid temps.
  • Wear warm gloves or invest in a pair of running gloves (like those made by Brooks) to keep hands warm, dry and covered.
  • Layer up in the RIGHT way (Side note: use your best judgement and shed a layer if you start to heat up too much while being active. Wrap it around your waist! ):
    • A moisture-wicking base layer against your skin,
    • An insulating middle layer,
    • A windproof outer layer, and
    • If wetness from snow or other precipitation is possible, an outer layer that’s also waterproof and breathable.

The Best Base Layers

If you have hyperhidrosis or expect to be working hard enough to get sweaty, your inner moisture-wicking layer is very important as it helps manage moisture (sweat) inside your clothing, which is crucial because body heat is pulled from wet skin 25 times faster than from dry skin, notes the AMC.

The best base layers for sweat management will be made of merino wool because merino insulates, wicks, and stays warm even when wet. 

Polypropylene (or “polypro”) is also a common fabric used for base layers because it’s designed to wick moisture, is effective at sweat-management, breathable, and quick-drying, but - be warned - it does not stay warm when wet, so wool is often a better winter bet. 

Middle Layer = Insulating Layer

Your middle layer will be your insulating layer. Often, this will be a fleece of varying thickness. The thicker the fleece or “loft”, the more insulation you can expect. A puffy jacket can also be a middle layer, but be aware that down does not retain warmth if it gets wet. For sweaty or wet conditions, synthetic-filled jackets, like those with PrimaLoft, will keep you warmer.

Outer Layers Fight the Elements & Need to Breathe

Your outer layer is your defense against rain, snow, sleet, etc.  It protects you from wetness coming at you externally. But if you are sweating (excessively or not), you’ll want to make sure your outer layer is breathable, too, so that you don’t trap sweat and the resulting wetness inside while you’re keeping the precipitation outside. Fabric membranes like Gore-Tex are waterproof and breathable.

Cold Out? Get Out Anyway!

Even if you have hyperhidrosis, outdoor exercise in the winter is not only possible it’s really beneficial in many ways:

  • Just a few minutes outside per day has been shown to improve mood and physical health, leading to reduced stress and increased self-esteem.
  • Being in nature can help increase focus and attention.
  • Natural daylight boosts serotonin in the brain, a key feel-good chemical that tends to reach its lowest levels in the winter. 
  • Exercise is more impactful in the winter because the body burns more calories in the cold.
