Potential Causes
Abnormal Vascular Response: Raynaud's disease is believed to involve an irregular vascular response to cold temperatures or emotional stress, resulting in exaggerated vasoconstriction and lowered blood flow to the extremities.

three. Environmental Triggers: Exposure to chilly temperatures is a common set off for Raynaud's assaults. Cold weather or immersion in chilly water can stimulate vasoconstriction in prone people, leading to vasospastic episodes.
