Ice baths are everywhere right now. Cold plunges, icy showers, refrigerated recovery tanks — social media has made cold exposure look like the ultimate wellness habit. But here’s what the trend glosses over: the research has largely been conducted on men, and a growing number of women’s health experts are questioning whether extreme cold is doing women’s bodies more harm than good.
Chinese medicine figured this out thousands of years ago.
This is something that comes up in nearly every single session I have with patients. Keeping the body warm is not a comfort preference — in Traditional Chinese Medicine (TCM), it is a fundamental health principle. Your body’s ability to digest food, fight infection, regulate your cycle, and heal from injury all depend on maintaining adequate internal warmth. When we continuously expose ourselves to cold — through food, drink, clothing, or cold therapy — we make every one of these processes harder.
Here is why cold exposure may be working against you (internally OR externally), and what supporting your body’s warmth actually does.
What is Yang energy — and why does it matter?
As warm-blooded creatures, our bodies are designed to function optimally at around 36–37°C. For most of us living in climates cooler than that, our bodies are continuously working just to maintain this temperature — before they can do anything else.
In Chinese medicine, all of the active processes in the body — digestion, immunity, reproduction, healing — are driven by what is called Yang: roughly translated as warmth, or warm energy. Think of it as your body’s inner pilot light. When Yang is strong and your body is warm, everything works. When cold depletes Yang, these processes slow down, stall, or simply cannot complete properly.
Yang deficiency — a state of insufficient warmth — shows up as chronic fatigue, sensitivity to cold, poor digestion, menstrual cramps and clots, low immunity, and slow recovery from illness or injury. Many women living with these symptoms have been told they are “just tired” or that their bloodwork is “normal.” TCM offers a different lens: the body is not broken, it is cold.
Cold and digestion: why your stomach needs warmth to work
Before your body can absorb a single nutrient from the food you eat, it needs to break it down the food into a liquid state that is warm (body temperature). This is the stomach’s primary job — and it requires heat to do it. Think of your stomach as a cooking pot that needs to keep simmering at all times.
When you eat warm, wet, cooked foods — soups, stews, congee, porridge, casseroles — much of that preparatory work has already been done outside the body. The food arrives at the stomach close to the temperature and consistency it needs to be, so the stomach can focus on moving it efficiently through to the small intestine for nutrient absorption, and then the large intestine before waste is excreted.
When you eat cold or raw foods, the body has to use significant energy to warm and break them down first. Think about how easy it is to squash a piece of carrot that has been simmering in a soup compared to a raw one — that difference in effort is happening inside your digestive system every time you eat something cold or uncooked.
Over time, a digestive system that is repeatedly chilled tends to give up on thorough extraction and simply rushes food through instead — often resulting in loose stools, bloating, fatigue after eating, and chronically poor nutrient absorption. The body is not malfunctioning; it is conserving energy by moving the problem out as quickly as possible rather than trying to warm and process food it cannot afford to.
Practical tip: If you love raw or cold foods, buffer them with warm, cooked elements in the same meal. Salads can include cooled roasted or steamed vegetables rather than purely raw leaves/garden vegetables. Cold fruit can be paired with warm porridge. The goal is not to eliminate cold foods entirely — it is to ensure the warm outweighs the cold so your digestive fire keeps burning.
Cold and immunity: your body fights infection with heat
One of the primary mechanisms by which your body fights infection is heat. When a pathogen enters the body, the immune system responds by creating local inflammation — redness, swelling, increased blood flow — to raise the temperature in the affected area and make it inhospitable to the invading organism. Systemically, the body raises its overall temperature through fever. These are not signs that something is going wrong; they are signs that your immune system is doing exactly what it is designed to do.
In TCM, the energy that governs immunity is called Wei Qi — defensive energy — and it is, again, a warm energy. A cold or flu is understood as an invasion of Wind Cold: the body’s defences were insufficient to keep cold out, so symptoms appear — runny nose with clear mucus, chills, body aches, frequent and copious urination. As the body rallies to fight back, signs of heat emerge: fever, sore inflamed throat, thicker yellow mucus. These heat signs are progress, not deterioration.
All of the energy required to generate this warmth has to come from somewhere. If you are continuously putting cold into or onto your body, you are depleting the reserves your immune system depends on. Keeping warm — through food, clothing, and lifestyle — is not just about comfort. It is active immune support.
Cold and women’s reproductive health: what your cycle is telling you
The uterus is one of the most warmth-sensitive organs in the female body. In TCM, cold in the lower abdomen is one of the most common underlying patterns seen in women with painful periods, heavy clotting, irregular cycles, and difficulty conceiving. When cold invades the uterus, it obstructs the free flow of blood and qi — and the result is often cramping, dark clotted blood, and a cycle that feels like a battle rather than a natural rhythm.
During pregnancy, the body intuitively understands this: progesterone causes the body to run slightly warmer than usual, creating the additional internal warmth needed to support new life. This is where the phrase “bun in the oven” comes from. Exposing the body to cold when it is already under the demands of reproductive activity — whether menstruating, trying to conceive, or pregnant — makes it harder to maintain this critical warmth.
Cold food and drinks during menstruation, sitting on cold surfaces, and inadequate clothing around the abdomen and lower back are all factors I discuss with many patients dealing with cycle-related symptoms. These are not superstitions — they are practical applications of a physiological principle that modern research is increasingly beginning to support.
Should you ice an injury? What Chinese medicine says about healing
Most of us have been taught to reach for ice after a sprain or strain. It reduces swelling, numbs the pain, and feels immediately relieving. But consider what the body is actually trying to do when it creates that swelling.
When you injure a joint or muscle, the body immediately increases blood flow to the area. This serves two purposes: it brings the immune cells needed to clear away damaged tissue, and it creates localised swelling that cushions the area and limits movement, preventing further injury while repairs are underway. The warmth and swelling you feel around a fresh injury are your body’s first-response healing team arriving on site.
Applying ice causes vasoconstriction — the blood vessels narrow, and blood flow to the area is reduced. The swelling goes down, which feels like an improvement, but the underlying healing mechanism has been interrupted. The immune cells can’t get in as efficiently, the tissue stays damaged for longer, and the natural protective cushioning is removed before the body is ready to give it up.
While cold numbs the pain in the short term, warmth supports the body’s natural process. A warm compress or heat pack on a recent injury — once the initial shock has passed — encourages blood flow, relaxes the surrounding tissue, and most patients find it deeply comforting rather than just temporarily numbing. The body is not making a mistake when it creates heat around an injury. It is asking for more of it.
Frequently asked questions
Is it ever okay to eat cold foods?
Yes. The goal is balance, not elimination. In hot climates or during summer, some cooling foods are appropriate and even beneficial. The key is proportion — ensuring the overall pattern of your diet supports warmth rather than depletes it. If you are dealing with active digestive issues, menstrual symptoms, low immunity, or you are recovering from illness, this is the time to prioritise warm and cooked foods most consistently.
Are ice baths safe for women?
The emerging research suggests women respond differently to extreme cold than men do — and most of the studies promoting the benefits of cold water immersion were conducted on male subjects. Women’s thermoregulatory systems, hormonal cycles, and reproductive physiology mean cold exposure carries a different set of risk-benefit calculations. From a TCM perspective, regular cold plunging is likely to deplete Yang over time and cause stagnation, particularly for women who are already dealing with cold patterns, menstrual issues, or fatigue.
What is Yang deficiency and how do I know if I have it?
Yang deficiency in TCM refers to a state where the body’s warm, active energy is insufficient. Common signs include feeling cold easily (especially in the hands, feet, and lower abdomen), chronic fatigue, poor digestion, loose stools, a pale complexion, low libido, heavy or clotted periods, and a general sense of sluggishness that rest does not fully resolve. If several of these resonate with you, it is worth speaking with a qualified TCM practitioner for a proper assessment.
Can warming practices really improve my menstrual cycle?
In clinical practice, yes — consistently. Warming the lower abdomen and lower back, shifting to predominantly warm cooked foods, avoiding cold drinks during menstruation, using heat packs around the time of your period, and keeping your feet and lower back warm are among the first and most impactful changes I recommend to patients with painful or irregular cycles. Combined with acupuncture and targeted herbal support, these dietary and lifestyle shifts form the foundation of cycle recovery in TCM.
The bottom line
Cold has its place in some contexts. But the wellness industry’s love affair with cold exposure has largely been built on male-body research, and is increasingly being questioned by women’s health experts and researchers alike.
Chinese medicine has offered a different perspective for centuries: warmth is the foundation of health. Protect it in the food you eat, the clothes you wear, the way you recover from injury, and the way you care for your body throughout your cycle.
When women start treating warmth as a non-negotiable — not an indulgence, but a basic requirement for a body that functions well — the changes in digestion, immunity, energy, and cycle are often faster and more significant than anything else they have tried. The body already knows how to heal. Our job is to stop making it cold.
