NHS blue or grey hands emergency cyanosis advice
Purple or blue hands can be due to cold exposure or reduced circulation, but it can also signal a serious heart, lung, or blood-flow problem.
Seek emergency help now if the colour change is sudden or accompanied by:
- Shortness of breath, chest pain, fainting, confusion, severe dizziness
- Blue/grey lips, tongue, face, or widespread skin change
- One hand that is painful, numb, very cold, swollen, or weak
- In a child or baby: poor feeding, unusual sleepiness, limpness, or breathing difficulty
These can be signs of inadequate oxygen or circulation. NHS cyanosis guidance advises emergency assessment for blue/grey colour with breathing, chest, or neurological symptoms.
If both hands are cold and the colour improves promptly after gently warming them, a temporary circulation response to cold is possible. Recurrent episodes, especially with fingers turning white, blue/purple, then red and painful or tingly, may be Raynaud phenomenon and should be assessed by a clinician.
Do not apply very hot water or direct heat to numb hands. Keep them warm gradually and remove tight rings. If the colour does not improve within a few minutes of warming, or this is new or unexplained, get urgent medical advice.
