Why do my fingers turn blue when exposed to low temperatures?

Hello samcluter,

Thank you for sharing your experience, that might be due to peripheral cyanosis, and it happens when there’s not enough oxygen-rich blood flowing to those parts. It can be caused by stuff like Raynaud’s disease, heart issues, or getting too cold. Oxygen is like fuel for our bodies – all our organs and tissues need it to do their thing. And we get that oxygen by breathing in air. We recommend consulting with a healthcare professional for a proper evaluation and diagnosis to determine the cause of your symptoms and ensure your well-being.
