Cold Weather Can Dehydrate Faster Than Summer Heat

1. Dry air = dry lungs. Every exhale releases water vapor. In cold weather, that loss increases by up to 60%.
2. Heated environments. Indoor heat strips humidity, drying out skin, lips, and sinuses.
3. Less thirst. Cold reduces your thirst sensation by up to 40%, so you drink less without realizing it.
4. Winter clothing. Layered clothes trap heat, leading to unnoticed perspiration.

• Headache or lightheadedness
• Dry skin and lips
• Dark urine
• Muscle cramps or fatigue
• Brain fog or irritability
   

Even mild dehydration can impair focus, slow reaction time, and raise heart rate.

1. Drink warm fluids. Herbal tea, hot water with lemon, or low-sodium broth hydrate and warm you.
2. Eat your water. Citrus fruits, cucumbers, and soups contribute to daily intake.
3. Humidify your space. Adds moisture to air and prevents respiratory dryness.
4. Balance electrolytes. If you exercise or sweat in cold weather, add electrolyte drinks—not just plain water.
5. Hydrate before caffeine. Start your morning with a full glass of water before coffee.

Dehydration strains the kidneys, heart, and brain. It also worsens skin dryness, sinus irritation, and fatigue—issues that already peak in winter.

Because care should be as mobile as you are. If fatigue or dizziness persists, CallOnDoc can help evaluate whether dehydration—or something deeper—is the cause.
