Cold Hands in Winter? How Dr.Warm Heated Gloves Protect You from Frostbite
Winter is beautiful—but also brutal. For many people who spend extended time outdoors, cold hands aren't just uncomfortable—they can be dangerous. From runners and delivery workers to cyclists and winter sports enthusiasts, prolonged exposure to low temperatures can lead to numbness, stiffness, and in severe cases, frostbite.
Frostbite can occur when skin temperature drops below 0°C (32°F), and fingers are especially vulnerable due to poor circulation and exposure. Once damage sets in, recovery can be long, painful, and sometimes permanent.
That’s why it’s not enough to wear regular gloves in freezing weather. You need advanced protection—like the Dr.Warm Heated Gloves.
