Why do I get cold hands all the time?

Hands are your body's radiators: when core temperature matters, vessels in the fingers clamp down to conserve heat for the organs, and the hands pay the price. That reflex runs stronger in some people than others - less body fat to insulate, a naturally cooler set point, a chilly office, or a sedentary day all turn it up, which is why some people type with numb fingers while their colleagues feel fine. The NHS describes the extreme version as Raynaud's: blood stops flowing properly to the fingers and toes in response to cold, anxiety, or stress, and the fingers change colour - white or blue, then red as flow returns - often with pain, numbness, or pins and needles. It is common and usually manageable with warm gloves and hand-warming habits. MedlinePlus's cold intolerance page names the medical patterns worth ruling out when hands are always freezing: anaemia, an underactive thyroid, and blood vessel problems such as Raynaud phenomenon. The practical sort: if your hands are simply cold but otherwise work normally, keep the core warm (a warm torso sends more blood outward), keep moving, and wear gloves before your hands get cold rather than after. If your fingers dramatically change colour in the cold, that is Raynaud's territory - still usually self-managed, but mention it to a GP because it sometimes pairs with other conditions. And if the cold hands come with constant tiredness, pale skin, breathlessness on stairs, or feeling cold everywhere while others are comfortable, ask for a blood test - anaemia and thyroid are both simple to check and simple to treat.
