Social media praises drinking hot water in the morning, but the benefits are questionable
Every morning, millions of people start their day with a cup of coffee or tea, but recently TikTok and other social media platforms have been flooded with videos about a “magical” habit — drinking hot water on an empty stomach. Bloggers reference traditional Chinese medicine and promise accelerated metabolism, perfect digestion, and even relief from menstrual pain. It sounds tempting, but the real benefits of hot water are far more modest than influencers claim. Let’s figure out what’s true and what’s just pretty packaging for ordinary hydration.
Why People Drink Boiling Water in the Morning
The habit of drinking warm water is not a social media invention. In China, Japan, and India, people have been starting their day with a cup of boiling water for centuries. In traditional Chinese medicine, it is believed that cold water “slows down” the internal qi energy and harms digestion, while warm water, on the contrary, helps the body wake up and kickstart metabolic processes.
This idea made its way into Western pop culture through bloggers around 2023–2024 and has only been gaining momentum since then. A typical video looks like this: a girl in a cozy kitchen pours boiling water into a glass, adds a slice of lemon, and tells how in a month her “skin cleared up, puffiness went away, and bowel movements normalized.” The comments are full of enthusiasm, and the view counts are in the millions.
The problem is that personal experience is not a clinical study. Dietitian Diane Lindsay-Adler puts it bluntly:
Hot water can be pleasant, and that matters, but its benefits are often exaggerated.
How Warm Drinks Help with Colds
Let’s start with what actually works. If you have a sore throat or a stuffy nose, warm liquids can indeed provide relief. And this isn’t folk medicine — it’s a fact confirmed by research.
Back in 1978, scientists showed that hot soup and warm water help clear nasal passages of mucus significantly faster than cold drinks. Moreover, the effect disappeared if the hot drink was consumed through a straw — meaning it wasn’t just about the liquid’s temperature, but also about the warm steam the person inhales.
Family physician Natasha Bhuyan recommends adding honey and lemon to warm water when you have a cold. Honey coats the irritated throat, and the steam helps you breathe more freely. But there’s an important nuance: “relieving symptoms” and “curing” are completely different things. Warm drinks don’t destroy viruses and bacteria. If your body temperature stays above 38.5 degrees for more than three days, no tea can replace a visit to the doctor.

How Warm Water Improves Digestion
The second popular argument in favor of morning boiling water is improved bowel function. And here, science partially sides with the bloggers, though with caveats.
When liquid enters the stomach, nerve endings send a signal to the rest of the gastrointestinal tract: “Attention, something has arrived, get ready to work.” Associate professor of nutrition Allison Miner explains that warm liquid can amplify this response and trigger the so-called gastrocolic reflex — the natural urge to empty the bowels.
This is why gastroenterologists often recommend starting the morning with a warm drink, especially if the patient has constipation issues. The effect here is more neurological than chemical: warm water gently “wakes up” the digestive system after a night’s sleep.
But it’s important to understand that hot water doesn’t “burn fat,” doesn’t “flush out toxins,” and doesn’t “boost metabolism” in the way social media claims. The thermal effect of liquid is so small that it can be disregarded. For comparison: to “burn” the calories from a single banana, you would need to drink about 30 liters of ice-cold water — and only because the body spends energy heating it up. With hot water, this mechanism doesn’t work at all.
Health Risks of Hot Water
You might think, what could be more harmless than plain water? But there are pitfalls here too. The main one is temperature.
The World Health Organization classifies beverages hotter than 65 degrees Celsius as potentially carcinogenic for the esophagus. Regular consumption of scalding hot liquids increases the risk of developing cancer. This doesn’t mean you need to drink only ice-cold water, but boiling water straight from the kettle is definitely a bad idea. The optimal temperature is between 40 and 60 degrees, when the liquid feels pleasantly warm but doesn’t burn your tongue.
Another point: if you have heartburn or gastroesophageal reflux disease (GERD), hot water on an empty stomach can worsen discomfort. In that case, it’s better to start with room-temperature water.
Finally, there’s a psychological trap. A person who believes in “hot water detox” may ignore real health problems, attributing everything to “not having cleansed yet.” No water can replace a balanced diet, physical activity, and regular medical checkups.
Should You Drink Hot Water in the Morning?
If you boil all the science down to a simple answer, it would be this: hot water is a perfectly normal way to start your day and stay hydrated, but nothing more. It can relieve nasal congestion during a cold, gently stimulate digestion, and simply be a pleasant morning ritual.
However, there is no basis for attributing medicinal or weight-loss properties to it. Your body handles “detox” perfectly well on its own — that’s what your liver and kidneys are for.
If you enjoy drinking warm water in the morning — go ahead, just let it cool down a bit. And if you prefer coffee or cool filtered water — that’s perfectly fine too. The main thing is that you drink enough fluids throughout the day, and whatever form or temperature they come in — your body will figure it out on its own.
