The UK Health Security Agency has activated amber and yellow cold health alerts across England this week, responding to a significant temperature drop that began on Monday.
With the cold snap expected to last until Friday, medical experts are warning that unusual sensations in your hands and feet could signal more than just typical winter chill.
Understanding Raynaud's Phenomenon
Dr Sam Firoozi explains that our autonomic nervous system naturally regulates blood flow to extremities, constricting blood vessels in cold conditions to preserve core body temperature.
However, some people experience an exaggerated version of this response. Raynaud's phenomenon involves severe blood vessel constriction that can cause distinct white or blue discolouration in fingers and toes, often accompanied by significant pain.
This condition can occur independently or be linked to underlying health issues including autoimmune diseases, nerve injuries, or as a side effect of certain medications.
When to Seek Medical Advice
While cold hands are common in winter, specific warning signs should prompt a consultation with your doctor.
Medical attention is recommended if you experience extreme discolouration that takes a long time to correct, becomes permanent, or is accompanied by burning or throbbing pain.
These symptoms could indicate a more serious underlying condition that requires proper diagnosis and management.
Treatment Options Available
The approach to managing Raynaud's varies depending on severity. For mild cases, simple measures like keeping warm with gloves and thermal socks may provide sufficient relief.
More severe instances might require medication to improve blood circulation, while in the most serious cases, surgical options could be considered to address the problematic blood vessel constriction.
With cold temperatures set to continue throughout the week, being aware of these symptoms could help people distinguish between normal chilly sensations and potential health concerns requiring professional assessment.
