When it’s this cold outside, this isn’t just “winter weather.” It’s a stressor on the body.
In temperatures this low, a few things matter more than usual:
• Limit prolonged outdoor exposure. Extreme cold constricts blood vessels and stresses the cardiovascular and respiratory systems. Short trips outside, layered clothing, and protecting hands, feet, ears, and face make a real difference.
• Protect your lungs. Breathing in very cold, dry air can trigger coughing, chest tightness, or asthma symptoms. Covering your mouth and nose with a scarf or mask helps warm the air before it reaches your lungs.
• Hydrate and nourish intentionally. Cold suppresses thirst, but dehydration increases fatigue, headaches, and susceptibility to illness. Warm fluids and regular meals help maintain energy and immune function.
• Pay attention to early warning signs. Persistent cough, shortness of breath, dizziness, or unusual fatigue shouldn’t be ignored, especially in extreme temperatures.
Stay warm, Chicago.
