Constantly cold hands and feet are a sign of danger: They should be checked immediately.

Regina Giblin, a senior nurse at the British Heart Foundation (BHF), explained the relationship between cold limbs and circulation: "In cold weather, blood vessels constrict, which increases heart rate and blood pressure."

Hands and feet may appear cold, pale, or purplish as the body prioritizes vital organs such as the brain, lungs, and kidneys.

This becomes even more pronounced if circulation is poor or the heart is not functioning properly.

IT MAY ALSO BE A SIGN OF OTHER DISEASES

Cold hands and feet can be caused not only by high blood pressure but also by low blood pressure, heart failure, peripheral artery disease, thyroid problems, diabetes, anemia, and even stress or anxiety.

Raynaud's disease is also a common condition characterized by this condition. In Raynaud's, blood vessels suddenly narrow, causing fingers and toes to turn blue, white, or purple.

IN WHICH CASES SHOULD YOU CONSULT A DOCTOR?

Giblin emphasizes that you should see a doctor without delay in the following situations:

• Hands or feet constantly remaining cold even in a warm environment,
• Bruising, paleness or mottled appearance on the skin,
• Numbness, tingling, pain,
• Formation of wounds or ulcers on the legs.

Hypertension is one of the leading causes of heart attack and stroke. However, because it doesn't have any obvious symptoms, it often goes unnoticed. Therefore, experts recommend paying attention to complaints of cold hands and feet and regular blood pressure checks.
