Catching Every Cold That Goes Around
If you seem to pick up every bug that passes through, run down for weeks after each one, or feel your defences drop whenever you are tired or stressed, Traditional Chinese Medicine has a clear way of explaining it and a practical way of working on it. In TCM, your resistance to illness depends on a protective energy called wei qi, or defensive qi, that circulates near the body's surface and guards against external threats. When wei qi is strong, you shrug off most bugs. When it is weak, you catch what goes around and take longer to recover. Acupuncture, moxibustion, and supportive lifestyle changes aim to rebuild that defensive layer so you get sick less often and bounce back faster.
This is preventive work more than crisis treatment. TCM has always placed great value on strengthening the body before illness takes hold, and that is where this approach is at its best.
What Wei Qi Is and Why It Weakens
Wei qi is described in TCM as the most active and protective form of energy in the body. It travels just beneath the skin, controls the opening and closing of the pores, warms the surface, and forms the first line of defence against external pathogens such as wind and cold. You can think of it as the body's frontier guard.
Wei qi is generated with the support of the Lung and the digestive system, which is why weak digestion, poor sleep, overwork, and prolonged stress all erode it. A few patterns commonly sit behind recurrent illness.
Lung qi deficiency. When the Lung energy that governs the body surface is weak, the protective layer is thin. People with this pattern catch colds easily, sweat without exertion, and feel their resistance falters at the first sign of a cold draft.
Spleen qi deficiency. Because the digestive system supplies the raw energy that becomes wei qi, weak digestion starves the defences. This pattern brings fatigue, loose digestion, and an immune system that never quite has enough fuel to do its job.
Depletion from stress and overwork. Long term stress drains the reserves the body draws on to maintain its defences. People in this pattern often notice they get sick precisely when they finally slow down after a stretch of pushing hard.
How TCM Strengthens Your Defences
The aim of treatment is to rebuild wei qi at its source, by strengthening the Lung and digestive energy that produce it and by clearing anything that is draining the system. This is steady, cumulative work rather than a quick fix, and it suits people who want to change their baseline rather than just treat the next cold.
Acupuncture is used to tonify Lung and Spleen qi, support digestion, and calm the nervous system so the body can divert energy back into its defences. Points on the forearms, lower legs, and upper back are commonly chosen for immune support. Many people notice their sleep and energy improve alongside their resistance, which makes sense, because rest and digestion are where wei qi is built.
Why Moxibustion Matters Here
Moxibustion is one of the most valued tools in TCM for building defensive qi. It involves warming specific acupuncture points with smouldering mugwort herb, gently driving warmth and energy into the body to tonify and protect. For immune support, moxibustion is often applied to points on the lower leg and lower abdomen that are traditionally associated with building strength and reserves.
The warming nature of moxibustion is especially suited to people who feel cold, tired, and depleted, the very people whose wei qi tends to run low. It is a comfortable, deeply warming treatment, and many patients describe a pleasant sense of being fortified afterwards. In traditional practice, courses of moxibustion at the change of seasons were used specifically to head off the wave of colds that comes with shifting weather. If you would like to understand the technique in more detail, our guide on what moxibustion is and how it works walks through it fully.
Building Immunity Between Sessions
Treatment works best when your daily habits support the same goal. Wei qi is built and conserved through rest, warmth, and steady digestion, so a few simple practices make a real difference.
- Protect the back of your neck and upper back from cold drafts and direct air conditioning, the classic entry points for wind and cold in TCM.
- Prioritise sleep, since the body rebuilds its defences overnight and chronic short sleep keeps wei qi low.
- Eat warm, cooked, easy to digest meals to give the digestive system the energy it needs to supply your defences.
- Manage stress before it becomes depletion, with rest built in rather than pushing until you crash.
- Stay reasonably active without overexerting, since gentle movement supports circulation while overtraining drains reserves.
Worth Doing Before You Get Sick
The strength of this approach is that it works on prevention. Rather than waiting for the next cold, you build a stronger baseline so fewer bugs take hold and the ones that do pass through faster. We are honest that this takes a course of treatment and consistent habits, and we do not claim to make anyone immune to illness. What we aim for is a sturdier, better defended system.
If you are tired of catching everything that goes around, especially in the run up to a season change, book a session at Piraluna and we will assess your pattern and build a plan to strengthen your defences. Claire, who trained at Chengdu University of TCM, will tailor the acupuncture and moxibustion to where your wei qi needs the most support.
