Which non-pharmacologic measure is recommended to help prevent Raynaud's episodes?

• A. Avoid Warm Exposure
• B. Engage in Regular Intense Exercise
• C. Avoid Cold Exposure
• D. Take Caffeine

Answer: (C)

Raynaud's episodes come from an exaggerated vasoconstrictive response of digital arteries to cold, leading to color changes, numbness, and pain. The most effective non-drug measure to prevent attacks is avoiding cold exposure and keeping the hands and feet warm, such as wearing gloves, proper layers, and minimizing sudden temperature changes. This directly limits vasospasm and reduces frequency of episodes. Other choices don’t fit as well: avoiding warm exposure would worsen symptoms, regular intense exercise isn’t specifically preventive for vasospasm, and caffeine can worsen vasoconstriction.
