Winter is when many people notice a particular kind of cold: it sits in the lower back and the knees, and a jumper does not quite reach it. Traditional Chinese medicine has a framework for this experience, called Kidney Qi, and a seasonal idea that goes with it: winter is the time to store energy instead of spending it.
This article explains that framework in plain terms, says where it stops being useful, and then turns it into a short Qigong sequence you can do seated or standing. It takes about ten minutes and asks very little of stiff joints. For winter Qigong for Kidney Qi, the movements below are a gentle starting point.
What Kidney Qi means in Chinese medicine, and what it does not mean
In Chinese medicine, “Kidney” is not the organ your doctor would scan. It names a network of functions described in classical texts such as the Huangdi Neijing (the Yellow Emperor’s Inner Classic). In that system the Kidney is said to store jing, often translated as essence, the deep reserve a person draws on across a lifetime. It is also linked to the lower back, the knees, the bones, the ears and the body’s tolerance of cold.
Kidney Qi is the working energy of that system. When practitioners describe it as strong, they mean someone who feels steady, warm in the lower body and well resourced. When they describe it as depleted, they usually mean tiredness, a cold or weak lower back, achy knees, and a low tolerance for cold weather.
It helps to be clear about the limits:
- Kidney Qi is a traditional framework, a way of organising observations about the body. It is not a measurement of how your kidneys work.
- A Qigong practice cannot treat kidney disease, and nothing here claims to.
- Kidney function is checked with blood and urine tests, which only a doctor can arrange.
Used honestly, the idea is a lens for noticing how you feel in winter and a reason to practise in a particular way. It does not replace medical care.
Why winter is the season of storing, and where that idea comes from
The Huangdi Neijing describes the seasons as a pattern to live by. Spring is for beginning, summer for full growth, autumn for gathering in, and winter for what the text calls closing and storing. In its chapter on the four seasons, it advises going to bed earlier, rising later with the daylight, and keeping warm. It also advises against exertion that makes you sweat heavily, because that spends energy the body is meant to be saving.
Winter is paired with the Kidney in this system, along with the element of water. Water in winter is still and deep, and sits low. Seen this way, winter is a season for conserving, quiet, and a downward and inward direction of attention.
You do not have to accept the whole system to find the advice sensible. Shorter days, colder air and stiffer joints do make most people want less rushing and more warmth. The traditional framework simply says to go with that instinct instead of fighting it, and then gives you a practice to go with it.
Qigong fits this season well because it is slow and low in effort. It aims to gather attention in the lower belly, which Chinese medicine and Qigong call the dantian, and to warm the lower back. It does not aim to build a sweat.
When feeling cold is a Qigong question and when it is a question for your doctor
Feeling the cold more in winter is common, and a gentle practice can be a pleasant way to feel warmer and more settled. Persistent cold is a different matter. If you are cold all the time, even in a warm room, or the cold is new, worsening or comes with other changes, see a doctor.
Health services such as the NHS and the Mayo Clinic list medical causes of cold intolerance, including an underactive thyroid, anaemia and circulation problems. Those are checked with simple tests, and they are treatable. Please see a doctor if you notice any of these:
- Cold that does not ease in a warm room or with warm clothing.
- Unusual tiredness, weight change, or hair and skin changes alongside the cold.
- Fingers or toes that turn white or blue in the cold.
- Numbness, swelling or pain in the lower back, knees or legs that is new.
- Dizziness, or any change in how often you pass urine.
A Qigong practice can sit alongside medical care. It is not a reason to delay it. If a doctor has found nothing wrong and you simply feel the cold in your bones, the sequence below is a reasonable thing to try.
Setting up: warm layers, a steady stance and slow lower belly breathing
Practise in a room that is comfortably warm and wear layers you can loosen. The lower back and belly should be covered, because these are the areas the practice is about. Socks or soft shoes help on a cold floor. If you are unsure what suits stiff joints, what to wear for Taiji practice when your joints are stiff covers it.
You can do the whole sequence seated on a firm chair with your feet flat, or standing. For standing:
- Place your feet about shoulder width apart, toes pointing forward.
- Soften your knees slightly so they are not locked. They should stay over your feet, not drift inward.
- Let your tailbone hang down, your shoulders drop, and your head feel lightly lifted.
- Rest your tongue gently behind your upper front teeth, and let your eyes soften.
The breathing underpins every movement. Breathe in through the nose, and let your lower belly expand gently, below the navel. Breathe out slowly and let the belly settle back. The chest and shoulders stay quiet. Keep the breath unforced, with no holding and no strain. If it is new to you, how to breathe in Taiji Quan with abdominal breathing walks through it step by step.
Take about six slow breaths before you begin, simply noticing the belly rise and fall.
Four quiet movements for warming the lower back and gathering energy in the belly
Do each movement slowly, for the number of repetitions given, and keep to a range that feels comfortable. Stop if anything hurts. A little warmth or a pleasant tingling is normal. Pain is not.
1. Warming the lower back
Rub your palms together briskly until they feel warm. Place them on your lower back, at the level of your waist, with the heels of the hands on either side of your spine. Rub up and down firmly but kindly, along the broad muscles on either side of the spine, for about thirty seconds. This is a traditional Qigong self-massage, and the area it covers is the one Chinese medicine associates with the Kidney.
Breathe slowly as you rub. Then rest your hands there for three slow breaths and feel the warmth.
2. Turning the waist and tapping
Let your arms hang loose. Begin to turn your waist gently left and right, so that your arms swing around your body like loose cords. The hands tap softly on the belly as you turn one way, and on the lower back as you turn the other way. The hips and knees stay quiet and facing forward, and the turning comes from the waist.
Keep the movement relaxed and let momentum do the work. Do about twenty turns, or one to two minutes. If you are seated, turn the upper body only and keep your feet planted.
3. Scooping and gathering
Bend your knees a little, or lean forward slightly if you are seated, and let your hands pass down the outsides of your legs towards your feet. Then turn the palms upward as if scooping water. Rise slowly, bringing your hands up the front of your body to rest over your lower belly, one hand over the other.
Breathe in as you rise and gather. Breathe out as you rest the hands on the belly and let the breath settle. Repeat six times. This is the heart of the sequence: you imagine collecting warmth from the ground and bringing it in.
If bending is uncomfortable, make the movement smaller. Keep the knees bent only a little, and think of scooping from around knee height. For sore knees, five small adjustments that make Taiji kinder on sore knees are worth reading before you start.
4. Resting at the lower belly
Finish by standing or sitting quietly with both hands over the lower belly, below the navel. Breathe slowly into the space beneath your hands. Imagine, without strain, a soft warmth collecting there, the way water settles in a basin.
Stay for one to two minutes. When you are ready, rub your hands together and gently stroke them down your face and along your arms, then open your eyes if they were closed.
Making the practice part of a short winter evening, alongside rest and warm food
Evening is a good time for this sequence, because the closing and storing idea suits the end of the day. Practise before supper or an hour or so after, rather than straight after a large meal. Then continue the quiet: dim the lights, keep the room warm, and put screens away earlier than usual.
Three things work together:
- The practice. Ten minutes of the sequence above, or just the first and last movements on tired days.
- Warmth in what you eat. Cooked, warm food is traditionally preferred in winter. Warming foods for stiff winter joints has ideas that fit.
- Rest. In the classical advice, rest is part of the season’s work. If you want the longer argument, rest is part of your Qigong practice, not a break from it.
Going to bed a little earlier in winter follows the classical text’s own advice. Nothing needs to be perfect. Even a few evenings a week of this routine gives you a chance to notice whether you feel steadier and warmer in the lower body.
If you cannot manage ten minutes, do less. A short practice done regularly is easier to keep up through the dark months than a long one you drop after a week.
One thing to try tonight
Tonight before bed, sit or stand comfortably and rest both hands on your lower back, palms against the muscles either side of the spine. Breathe slowly into your lower belly for two minutes. Let the belly widen on the in-breath and soften on the out-breath, and notice any warmth beneath your hands.
That is the whole practice for tonight. If you would like to go further, the article on five books for a small Taiji and Qigong shelf describes what each book is for, so you can choose a trusted one to start with.
