Why do cuts hurt more in cold weather?
Show answer & explanation
Answer: Cold makes nerves more reactive
Ice crystals form in wounds — Wrong. Ice crystals don't form in minor cuts at typical cold weather temperatures. The pain is from nerve response.
Skin becomes more sensitive overall — Wrong. Skin sensitivity does increase, but the main reason is that cold temperatures make nerve endings more reactive to pain signals.
Cold makes nerves more reactive ✓ — Correct! Cold temperatures make nerve endings more sensitive and reactive. They send stronger pain signals to the brain. Additionally, cold causes blood vessels to constrict, reducing blood flow and increasing discomfort.
