The Weather Turns and You Catch Everything? Always Getting Sick, Explained
Updated: Oct 5
By Hansung Jang, L.Ac. · Lena Kim Acupuncture
The first cool morning of October, someone at work starts sniffling. You already know how this goes. By Thursday your throat is scratchy. By the weekend you are on the couch with a box of tissues. And while everyone else shakes it off in three days, you are still coughing two weeks later, just in time to catch the next one.
You are not careless. You wash your hands, you take your vitamin C, you went to bed early last night. But you also sweat the moment you climb a flight of stairs, your collar is damp after a brisk walk, and a draft from an open window feels like it goes straight through you. By evening you are tired in a way that sleep does not quite fix.
If you feel like you are always getting sick when the seasons change, you are not imagining the pattern. It is one of the most common things we hear at the clinic in Lake Forest every fall, as the temperature swings between warm afternoons and cool Orange County mornings and the colds start circulating through offices and classrooms. In East Asian medicine, always getting sick is not read as simply "weak immunity." It is read as a specific pattern, and the pattern decides what actually helps.
What East Asian Medicine Means by Your "Outer Defense"
In East Asian medicine, the body has a protective layer at its surface called 衛氣, usually translated as defensive qi. A useful way to picture it is as the body's outer gatekeeper. It sits at the skin and the pores, it warms the surface, and it decides what stays out and what is allowed to leave.
One of the clearest signs of how well that gatekeeper is working is sweat. A healthy surface opens the pores when you are hot and closes them when you are not. When the outer defense is depleted, the gate stops closing properly. You sweat with very little effort, sometimes while you are sitting still, and the same open gate that lets sweat out easily also lets cold and wind in easily. That is why East Asian medicine has long linked easy, spontaneous sweating with catching every cold that passes through.
Modern physiology describes something adjacent. Sweating, fluid balance, and the health of the tissues at the body's surface all depend on circulating proteins and on how well the body holds fluid where it belongs. When that system is underpowered, people tend to feel puffy, heavy, and easily fatigued at the same time that they feel easily chilled. East Asian medicine noticed this cluster long before it had the vocabulary to explain it.
The Herb Behind This Pattern: Huang Qi 黃芪
The herb East Asian medicine reaches for most often in this picture is Huang Qi 黃芪, known in English as astragalus root. It has been used in East Asian medicine for centuries to support that outer defense, and it is one of the most studied tonic herbs in the tradition.
Picture the person Huang Qi was described for. They walk up from the parking garage and arrive at their desk with a damp hairline. They wake up with the back of their shirt slightly wet even though the room was cool. Their face tends to be pale rather than flushed, their ankles look a little puffy by late afternoon, and their voice gets softer and thinner after a long meeting, as if talking itself costs energy. They are the first in the household to catch a cold and the last to recover, and every cold seems to settle in and linger rather than burn through. This is the classical territory of Huang Qi: a surface that cannot hold, sweat that leaks too easily, fluid that sits in the tissues, and a recovery that never quite completes.
In East Asian medicine, Huang Qi is understood to help the body build and hold, rather than to fight anything directly. It is often paired with Bai Zhu 白朮 (white atractylodes) and Fang Feng 防風 (saposhnikovia) in a classical formula whose name translates as "Jade Windscreen," a fitting image for an herb combination meant to stand between a depleted person and the wind. Astragalus has been studied in relation to immune function, with research interest in its polysaccharides and compounds called astragalosides. That research is interesting, but it is worth being honest about what it is. These compounds have been studied, not proven to prevent or cure illness, and the most important skill is not the herb. It is recognizing whether the person in front of you actually fits it.
When Always Getting Sick Needs a Physician, Not an Acupuncturist
Before any pattern matching, there is a line East Asian medicine does not cross, and a responsible practitioner will send you elsewhere first.
If you are getting infections that need antibiotics again and again, such as repeated sinus, ear, urinary, or chest infections, that deserves a medical workup. So does a fever that lasts more than three days, a high fever, shortness of breath, or a cold that improves and then suddenly gets worse. Frequent illness can also be the first visible sign of something else, including blood sugar problems, anemia, thyroid changes, or an immune condition, and those are found with a physician's exam and lab work, not with herbs.
There are also clear safety lines with Huang Qi itself. Because it is traditionally used to strengthen immune activity, it is not a casual choice for anyone with an autoimmune condition or anyone taking immunosuppressant medication, including after an organ transplant or on biologic drugs. In larger amounts, especially combined with licorice, it can push blood pressure up, so people with high blood pressure need a formula adjusted for them. It can also interact with diabetes medication. If you are pregnant or nursing, on blood thinners, scheduled for surgery, or taking regular prescription medication, do not start any herbal formula without the guidance of a licensed East Asian medicine practitioner who can review the whole picture.
Why Always Getting Sick Is Not One Problem
Here is the part that most immune-boosting advice skips, and it is the reason a full intake is not a formality.
"I'm always getting sick" is a sentence many different people say. Astragalus has a reputation as a general immune herb that everyone could use. That reputation is exactly the problem.
The first person is the Huang Qi 黃芪 person described above. They sweat easily, tire easily, look pale, feel the cold, and recover slowly. Their outer defense is depleted, and building it up is exactly what they need.
The second person says the same sentence but is built in the opposite direction. They run warm. Their face flushes, they are often thirsty, and every cold starts with a burning sore throat and comes on hard and fast. Their illnesses tend to follow stretches of overwork, short sleep, rich food, and stress, and they may be prone to constipation or skin breakouts. In East Asian medicine this is a heat and excess pattern, not a depleted one. Giving this person a warming, building herb like Huang Qi is like closing the windows in a room that is already too hot. The heat has nowhere to go, and the next sore throat can be worse, not better. This person needs heat cleared and their schedule changed long before they need a tonic.
Timing matters too. Huang Qi belongs to the space between colds, when the goal is to rebuild. In East Asian medicine, a building herb taken in the middle of an active cold with fever and body aches is traditionally thought to hold the illness in rather than help the body push it out. The same herb that is right in November can be the wrong choice on the second day of a fever.
This is why we take a full intake before recommending anything. We ask how you sweat, how your colds start, how long they take to leave, whether you run hot or cold, and how you sleep and eat. Those answers separate a depleted surface from a body that is overheated, and that difference decides whether astragalus helps or gets in the way.
 Jang's Clinical NoteWhen someone tells me they catch everything, the first question I ask is not about their immune system. I ask how they sweat. It sounds like an odd place to start, but sweat tells me a great deal. A person who sweats from walking across a room and wakes with a damp collar is telling me something about their surface. A person who barely sweats but flushes red and gets a burning throat with every cold is telling me something different. They will both describe themselves with the same words, and they need almost opposite care. The second thing I want to know is what their colds look like on the way out. Do they burn through and leave, or do they settle in and linger for weeks? A lingering recovery points me toward building. A hard, hot onset points me toward clearing. I find that the change of season is rarely the real cause. It is the test that shows where someone was already thin.

환절기만 되면 남들보다 먼저 감기에 걸리고, 한 번 걸리면 2~3주씩 끌리는 분들이 많습니다. 조금만 움직여도 땀이 나고, 찬바람이 몸속까지 스며드는 느낌이 들고, 저녁이면 쉽게 지치거나 발목이 붓는다면, 한의학에서 말하는 위기(衛氣), 즉 몸 겉면의 방어 기운이 약해진 패턴일 수 있습니다. 땀구멍을 제대로 닫지 못하니 땀은 쉽게 새고, 같은 이유로 찬 기운도 쉽게 들어온다고 보는 것입니다.
이런 분께 한의학에서 전통적으로 써 온 약재가 황기(黃芪)입니다. 백출(白朮), 방풍(防風)과 함께 옥병풍산(玉屏風散)으로 배합해, 바람을 막는 병풍처럼 겉의 방어를 세워 주는 방향으로 사용되어 왔습니다.
하지만 "면역에는 황기"라는 통념이 오히려 함정입니다. 똑같이 "감기를 달고 산다"고 해도, 열이 많고 얼굴이 쉽게 붉어지며, 감기가 늘 목이 타는 듯 아프게 세게 시작되는 분은 허증이 아니라 실열(實熱) 패턴입니다. 이분께 황기처럼 데우고 채우는 약을 쓰면 열이 빠져나갈 곳이 없어 오히려 악화될 수 있습니다. 또 열이 나고 몸살이 있는 감기 도중에는 황기 같은 보약을 피하는 것이 원칙이고, 감기와 감기 사이 회복기에 쓰는 약입니다.
항생제가 필요한 감염이 반복되거나, 3일 이상 열이 지속되거나, 호흡곤란이 있으면 먼저 의사의 진료를 받으십시오. 자가면역질환이 있거나 면역억제제를 복용 중인 분, 고혈압·당뇨약 복용 중인 분, 임신·수유 중이거나 수술 예정인 분은 반드시 전문가 상담 후 복용하십시오.
Let's Find Your Pattern
We take a full intake before recommending any formula. The right approach depends on your specific pattern, not a general symptom list, which is exactly why "I'm always getting sick" can call for building in one person and clearing in another. If every change of season seems to knock you down, we can help you find out which pattern is actually yours.
