When to worry
Cold extremities are usually ordinary. A small number of presentations are vascular or systemic emergencies, and they are recognisable by how quickly they came on rather than by how cold the hands feel. The first group below is the one to read twice.
Get help now — same day or emergency
- A limb that has suddenly gone cold, pale and painful, with no pulse felt at the wrist or ankle. This is an arterial occlusion and it is measured in hours.
- Cold, mottled skin with fever, confusion, or a rapid heartbeat — this can be sepsis.
- Cold sweats with chest pain, or with breathlessness.
- Cold hands and feet with a high fever and drowsiness, particularly in a child — the combination is a red flag for serious infection.
- A limb that is cold, swollen and painful after immobility or a long flight.
Get it looked at within days
- Colour changes in the fingers — white, then blue, then red — triggered by cold or stress. This is Raynaud phenomenon and a first episode should be assessed.
- Cold intolerance with weight gain, fatigue, constipation and dry skin — thyroid function.
- Cold hands with pallor, breathlessness and a rapid pulse — anaemia.
- Coldness in one limb only, or coldness with a change in the nails or hair on that limb.
- New cold extremities after starting a medicine. Beta blockers and some migraine drugs are common causes.
The rest of the page assumes none of the above. One structural point: the temperature of the hands is a poor measure of anything, because the body will sacrifice the extremities to protect the core. What matters is whether the trunk is warm or cold too.
One rule for this whole list: if you are not sure whether a line applies to you, treat it as though it does — and get it checked. Uncertainty is a reason to be seen, not a reason to wait.
Four kinds of cold extremities
The classical vocabulary distinguishes these by how far up the cold reaches and by what the core is doing. The second distinction is the one that changes the treatment direction, and it is the one most often missed.
Cold from fingers to wrists
The cold stops around the wrist and ankle rather than reaching the elbow or knee. Often with pale fingers, a fine pulse, and worse in cold weather.
Points to Blood deficiency with cold in the vessels — the type the classical formula in the sources was written for. Warming and nourishing rather than drying.
Cold up to elbows and knees, whole body cold
The cold reaches further, the person feels cold generally, and there is fatigue, a desire for warmth, and frequent pale urine.
Points to Yang deficiency. The measures are warming and supporting, and this is the type that responds to food and to warmth rather than to anything clever.
Cold hands with a hot trunk
The hands and feet are cold while the chest and abdomen feel hot, sometimes with thirst, restlessness, and a red face.
Points to The classical 真热假寒 pattern — heat deep inside, cold showing outside. This is the one where warming measures make things worse, and it is a reason to be assessed rather than to self-treat.
White, blue, then red fingers
Distinct colour changes in the fingers, sharply demarcated at the knuckle, triggered by cold or by stress, sometimes painful on recovery.
Points to Raynaud phenomenon. A vascular question, not a pattern question, and one where a first episode needs assessment.
What the patterns describe
The single distinction that matters is whether the core is warm. Cold hands with a warm trunk and a person who feels hot inside is a different state from cold hands with a cold trunk and a person who wants a blanket. In the traditional account the first is heat constrained internally, and the second is yang deficiency. The measures are opposite: one needs the surface opened and the interior cleared, the other needs warmth and support. Applying warmth to the first produces flushing, restlessness and worse sleep.
The second useful question is how far the cold reaches. Cold that stops at the wrist and ankle is described as a vessel-level problem — the blood is not filling the periphery, and the traditional reading is blood deficiency with cold. Cold that reaches the elbows and knees, with general cold intolerance and fatigue, is described at the level of yang itself. The first is more common in thin, pale, menstruating people; the second in older people and in long-standing fatigue.
What the tradition cannot do is distinguish Raynaud phenomenon from ordinary cold hands, or an arterial occlusion from either. Those are distinguished by looking at the colour, feeling for pulses, and asking how fast it happened. The one thing worth memorising from this page is that a limb which has gone cold suddenly, with pain and pallor, is an emergency and not a pattern.
Which patterns it belongs to
These are the patterns this symptom is conventionally grouped under. They are not competing diagnoses — most people meet one, and the point of the list is to show you which questions separate them.
Pallor, cold extremities to the wrist, palpitations, numbness, a thin pulse, a pale tongue.
The standard reading for cold that stops at the wrist and ankle.
Read the pattern page →Cold hands, fatigue, a soft voice, spontaneous sweating, breathlessness on stairs.
Coldness with fatigue and a sense of weakness rather than pallor.
Read the pattern page →Heaviness in the limbs, a cold clammy feeling, a greasy tongue coat, sticky stools.
A cold, heavy sensation rather than true coldness, worse in humidity.
Read the pattern page →Cold extremities with night sweats, five-palm heat, a red tongue with little coat, a thin rapid pulse.
For the cold-hands-with-hot-trunk presentation, which is the opposite reading.
Read the pattern page →The signs behind it
Each line below is one entry in the sign table — the same table the self-check draws its follow-up questions from. The tier says how strongly that sign points at the pattern: a defining sign is expected, a common one is usual, a supporting one is optional.

Not every sign listed here will apply to you — a sign only counts alongside the others. The self-check is the place to weigh them against your own answers.
Telling them apart
Four questions do most of the work. Each one splits the field in half, and after two or three the pattern is usually clear enough to act on — or clear enough to know that the answer is medical rather than traditional.
| Question | If yes | If no |
|---|---|---|
| Is the trunk warm or cold? | Warm, and you feel hot inside with a red face → heat constrained internally. Do not use warming measures. Get assessed. | Cold all over, and you want warmth → yang deficiency. Warming measures apply. |
| How far up does the cold reach? | To the wrist and ankle → blood deficiency with cold in the vessels. Nourishing and warming. | To the elbows and knees → a deeper yang deficiency reading, and the measures are slower. |
| Do the fingers change colour — white, then blue, then red? | Yes, triggered by cold or stress → Raynaud phenomenon. A first episode should be assessed before it is treated as a pattern. | No colour change, just cold → ordinary peripheral coldness. |
| Did it come on suddenly in one limb? | Yes, with pain and pallor → arterial occlusion. This is an emergency; call for help now. | Gradual, both sides → the pattern readings are more relevant. |
What you can do at home
None of this treats a named condition, and none of it replaces assessment. These are the ordinary measures attached to this symptom — low risk, and worth doing while you work out what is actually going on.
- Warm the trunk, not just the hands. A warm core is what keeps the periphery supplied; gloves on cold hands with a cold torso is the wrong order of operations.
- Eat something warm and substantial at the start of the day rather than fruit and coffee. This is the standard traditional measure for the deficiency type and it is testable within a fortnight.
- Move for ten minutes rather than sitting with a hot drink. Peripheral circulation responds to muscle activity more than to external heat.
- Do not use very hot water or a hot water bottle on fingers that have gone white and numb after cold exposure. Rewarm gradually — rapid rewarming of a Raynaud episode is painful and can cause tissue injury.
- If the hands are cold but the trunk is hot and you feel restless or thirsty, do not treat it with warming food or warming herbs. That presentation needs assessment.
Classical sources

阳气衰于下，则为寒厥；阴气衰于下，则为热厥。 yáng qì shuāi yú xià, zé wéi hán jué; yīn qì shuāi yú xià, zé wéi rè jué
When yang qi fails below, there is cold reversal; when yin qi fails below, there is heat reversal.
手足厥寒，脉细欲绝者，当归四逆汤主之。 shǒu zú jué hán, mài xì yù jué zhě, dāng guī sì nì tāng zhǔ zhī
For cold reversal of the hands and feet, with a pulse thin to the point of vanishing, the Danggui Sini decoction governs it.
肾气虚则厥，实则胀，五脏不安。 shèn qì xū zé jué, shí zé zhàng, wǔ zàng bù ān
When kidney qi is deficient there is reversal; when excess there is distension, and the five organs are unsettled.
The first citation is one sentence from a long chapter on reversal, and it is included because it establishes the pairing that the rest of the tradition depends on: cold extremities and hot extremities are not two severities of one thing, they are two opposite failures. The second names a formula and is here for the description rather than the prescription — note that it specifies the pulse, not the temperature of the hands, as the deciding sign.
