What is Raynaud's phenomenon?

Raynaud's phenomenon is a condition where the blood vessels in the hands and feet overreact to cold temperatures, causing them to constrict and leading to discoloration and pain.

What medical conditions are associated with Raynaud's?

Raynaud's is often associated with autoimmune disorders like scleroderma, rheumatoid arthritis, and systemic lupus erythematosus (SLE).

How can medications affect Raynaud's?

Certain medications, such as beta blockers used to treat heart conditions, can trigger Raynaud's by blocking the sympathetic receptors that regulate blood flow.

Doctors Warn of Dangerous Discoloration and Pain in Hands, Feet as UK Braces for Extreme Cold

On November 17, 2025, the UK braces for a significant drop in temperatures, with the UK Health Security Agency issuing cold weather alerts across the country. An amber alert is in place for the North East, North West, and Yorkshire and the Humber regions, while a yellow alert covers the rest of England until Friday.

While it's normal for hands and feet to feel chilly in cold weather, doctors caution that persistent or extreme discoloration and pain could indicate an underlying medical condition. Dr. Sam Firoozi, a cardiologist at HCA Healthcare UK's The Harley Street Clinic, explains that the autonomic nervous system regulates blood flow to the extremities, and an exaggerated response can lead to Raynaud's phenomenon.
