Winter dehydration is an overlooked workplace hazard that impacts safety, focus, and performance. Learn why cold-weather conditions increase fluid loss and how Sqwincher® supports safer, more hydrated workers all season long.

Most employers associate dehydration with heat stress in the summer—but winter dehydration is just as dangerous and far more common. Cold, dry air, indoor heating, layered PPE, and reduced thirst cues create the perfect conditions for fluid loss, even when workers don’t feel hot or sweaty. Source: Mayo Clinic – Cold weather dehydration

Across construction, industrial manufacturing, cold storage, food processing, transportation, and outdoor trades, winter dehydration quietly impacts safety, performance, and overall well-being. A winter hydration program is essential—and Sqwincher® provides the industry’s most effective electrolyte solution for Canadian workplaces.

Winter air holds very little moisture, and heated indoor environments often fall below 20–30% humidity. Workers lose more fluid through breathing, and skin and airways dry out quickly. Source: U.S. National Library of Medicine – Airway hydration & humidity

Cold conditions constrict blood vessels, tricking the body into thinking it’s hydrated. Workers feel 30–40% less thirsty—even while losing fluids. Source: University of New Hampshire – “Cold Weather Dehydration

Layers trap heat and boost sweat rates during physical tasks. Sweat evaporates quickly in cold air, so workers underestimate how much they’re losing.

High-risk environments include construction, logistics, cold storage, snow removal, mining, municipal services, and food processing.
