- Numbness
- Tingling sensations
- Burning feelings
- Cold fingers
- Mild discomfort
- Temporary loss of dexterity
Although these episodes can appear dramatic, they are often temporary and resolve once circulation improves.
Why Does It Happen More Often in Cold Weather?
The human body naturally responds to cold temperatures by narrowing blood vessels near the skin surface. This helps conserve heat and protect vital organs.
For people with Raynaud's phenomenon, however, this response can become exaggerated. Even mild exposure to cold environments may trigger significant vessel constriction in the fingers and toes.
Common triggers include:
- Winter weather
- Air-conditioned rooms
- Holding cold drinks
- Touching frozen foods
- Sudden temperature changes
Even emotional stress or anxiety can provoke an episode in some individuals.
Primary vs. Secondary Raynaud's
Healthcare providers generally classify Raynaud's phenomenon into two categories.
Primary Raynaud's
Primary Raynaud's occurs without an associated underlying disease.
Characteristics often include:
- Mild symptoms
- Symmetrical involvement of both hands
- Episodes triggered by cold or stress
- No permanent tissue damage
Most people with primary Raynaud's manage symptoms successfully through lifestyle modifications.
