SYMPTOM
Feeling unusually drained or sluggish when you've been exposed to or spent time in cold weather. Your body expends extra energy just to maintain its core temperature, and shorter daylight hours in winter can also affect your mood and sleep patterns, leading to this tiredness.
For general awareness only. This is not medical advice. If symptoms are severe or persistent, consult a healthcare professional.
Showing 8 causes
Cold-induced dehydration
Dry cold air makes you lose more fluid than you might realize, and being dehydrated tires you out. You're essentially running on low fluid levels.
Post-cold rewarming metabolic effort
Your body uses extra energy to warm up after being cold, which could leave you feeling tired. It's like your body just ran a mini-marathon to get back to normal.
Cold-induced raynaud's phenomenon
Blood vessels in your extremities narrow excessively in the cold, reducing blood flow and causing pain or numbness. This could make you feel generally drained and unwell.
Reduced vitamin d synthesis
Less sunshine in cold weather means your body makes less vitamin D, which is key for energy and mood. This could lead to a general feeling of tiredness.
Delayed cold urticaria response
Your skin could release histamine after cold exposure, causing a delayed itchy rash and sometimes a feeling of being unwell or fatigued. It's like a slow-burning reaction.
Winter sleep cycle disruption
Colder temperatures and less daylight could mess with your body's natural sleep rhythm, making sleep less restful. You wake up feeling drained and exhausted.
Cold stress response activation
Your body releases stress hormones like cortisol to cope with the cold, and prolonged release could lead to exhaustion. It's your body's way of saying it's had enough.
Cold-aggravated thyroid issues
Cold weather could sometimes make an underactive thyroid work even harder, exacerbating fatigue and low energy. This condition makes you sensitive to temperature changes.
