If you run out of steam before the day is done, get short of breath on the stairs, and would rather not talk much because even that takes effort, this may be the body type that sounds like you. In the old language of Chinese medicine, qi is your body's energy, and qi deficiency means running low on it.
Living like that wears you down, and it's hard to explain to anyone who hasn't felt it. The good news is that this is one of nine body types, a way your body leans rather than an illness. That means there are ordinary, everyday things you can adjust, and a Chinese care guideline written for each body type spells them out. This page walks you through them, and through a simple way to tell whether they're helping.
You tire easily. You get short of breath, you don't feel like talking much, and your voice tends to be quiet. You're often low on drive, and you break a sweat without doing much.
Wind, cold, heat, summer heat and damp all tend to get to you. You're not a person who shrugs off the weather.
Chinese medicine doctors also read your tongue and pulse. That takes someone in person; an acupuncture clinic near you can do it.
Chinese medicine doesn't start from the complaint. It starts from you. The same kind of discomfort can come from quite different body types, and what helps one can make another worse. So the first step is finding out which way your body leans. After that, the part you can do yourself is ordinary: what you eat, how you sleep and rest, how you move, and how you look after your mood, chosen to suit your type. None of it is quick. It's a slow, steady nudge, and it works alongside your regular doctor, not in place of one.
Tiring easily sits right at the center of this type: low energy, getting short of breath, sweating without effort. The approach here is slow and steady. It means resting before you're empty rather than after, eating food that's nourishing but easy on your stomach, and moving gently but often. Everything is set out below. If you're tired and your blood work keeps coming back normal, Why am I so tired but my labs are normal? may help too.
Not in the sense of a pill that makes it go away. Qi deficiency isn't a disease; it's the way your body leans. What you can do is nudge that lean with everyday habits, food and movement, and keep an eye on how you feel. It's gradual, so judge it over a few weeks, not by any single morning.
Breaking a sweat without much effort is part of this type. The guideline has one practical point that goes with it: when you've been sweating, stay out of the wind and drafts.
For this type, the one thing we'd start with is stopping short of your limit, at work and when you exercise. End a walk while you could still have gone a little further. Go more often, not harder. It's the whole theme of this type: using up everything you have costs more than it gives back.
How to tell if it's helping. Keep a notebook by the bed. It takes about half a minute each evening.
For the first three days, change nothing. Just score these three, each from 1 (bad) to 5 (fine). Those days are what you compare against later.
Then start your one thing, and each evening add one more line: Did I stop short today? Yes or no. Don't judge by one day: everyone has flat days whatever they do. Keep going for two weeks, then look back.
Reading your two weeks.
Your mood. Keep an easy, hopeful frame of mind, and try not to wear yourself out mentally. The guideline suggests bright, lively music.
Daily life. Balance work with rest, don't overwork, and keep a regular schedule. Don't sit in a draft with sweat still on you. Keep your home bright and warm-toned rather than dim.
Exercise. Gentle, often, built up little by little. Skip heavy loads, all-out effort and anything that makes you hold your breath. Tai chi and qigong routines like ba duan jin suit this type well, and so do slow jogging and brisk walking. One breathing habit the guideline mentions: keep your mouth closed and let your breath stay slow and even.
If you live with a long-term condition such as high blood pressure, diabetes or kidney disease, or you're in the middle of any illness, check with your own doctor before changing your routine.
Eat more. Think warm, nourishing and easy to digest.
The simplest change is the starch:
Then the protein:
Also good:
Eat less. Go easy on:
You may well see yourself in two or three types; that's normal. The assessment asks 26 questions, takes about three minutes, scores all nine types, and tells you which one stands out, or that none does. It uses the questions and scoring lines of China's national standard, translated into English. It's a self-check to help you get to know your body. It isn't a diagnosis, and it can't replace a practitioner who sees you in person.

A runner? Why am I so tired, cold or sweaty after running? Tired with normal blood work? Why am I so tired but my labs are normal?
If tiredness or breathlessness is new, severe or getting worse, if you've been feeling low most days, or if you're sweating heavily at night or losing weight without trying, talk to a doctor. If you get breathless at rest, see one promptly, and if you have chest pain or suddenly can't catch your breath, call 911. Home experiments are for the everyday kind.
The nine body types come from Wang Qi, a professor at Beijing University of Chinese Medicine. He and his colleagues first sorted people into seven types in the late 1970s, kept refining the idea for more than twenty years, and published the nine-type system in 2005.
It didn't stay an idea on paper. China brought body-type checks into its basic public health service, which offers residents aged 65 and over a check once a year, along with everyday advice for their type. In community clinics the check has been used more than 570 million times, and it's offered in the preventive care departments of over 1,700 Chinese medicine hospitals.
As it spread, clinics weren't all doing it the same way, and the quality varied. So China made it a national standard, giving every clinic one agreed method to follow. It was drawn up by a team of 37 from 20 hospitals, universities and other institutions, with Wang Qi first among them, and came into force in April 2026. The assessment on this site uses that standard's questions and scoring lines, translated into English. The everyday advice for each type comes from a care guideline for adults built on the same nine types.
It's a way of understanding your body's everyday tendencies, not a medical test, and it sits alongside your doctor, not instead of one.
