Which of the following lifestyle recommendations is FALSE for managing Raynaud's phenomenon?

Caffeine-containing drinks are actually known to potentially exacerbate symptoms of Raynaud's phenomenon rather than decrease them. Caffeine is a stimulant that can cause vasoconstriction, meaning it narrows the blood vessels, which is counterproductive for someone suffering from Raynaud's where the main concern is insufficient blood flow to the extremities due to vasospasm.

In contrast, wearing gloves or mittens in cold weather helps to maintain warmth in the hands, thereby reducing the likelihood of vasospasm. Stopping smoking is critical as nicotine is a vasoconstrictor, and regular exercise is beneficial because it improves circulation and may help reduce the frequency of episodes. Finally, managing emotional stress is essential since stress can trigger episodes of Raynaud's by promoting vasoconstriction. Therefore, the answer regarding caffeine is indeed the false lifestyle recommendation for managing Raynaud's phenomenon.
