The debate about whether drinking hot coffee makes you hotter has been ongoing for years. While some people swear that a hot cup of coffee on a sweltering summer day is the perfect way to cool down, others claim that it only makes them feel hotter. But what does the science say? In this article, we’ll delve into the world of thermoregulation, sweat, and caffeine to find out if drinking hot coffee really does make you hotter.
How the Body Regulates Temperature
Before we dive into the world of coffee, it’s essential to understand how the body regulates its temperature. The human body is designed to maintain a relatively constant internal temperature, around 98.6°F (37°C), regardless of the external temperature. This process is called thermoregulation.
The body has several mechanisms to regulate its temperature, including:
Sweating
Sweating is one of the primary ways the body cools itself down. When the body temperature rises, the hypothalamus (the temperature regulation center of the brain) sends a signal to the sweat glands to produce sweat. As the sweat evaporates, it takes heat away from the body, cooling it down.
Vasodilation and Vasoconstriction
Another way the body regulates its temperature is through vasodilation and vasoconstriction. Vasodilation is the widening of blood vessels, which allows more blood to flow to the skin’s surface, releasing heat. Vasoconstriction is the narrowing of blood vessels, which reduces blood flow to the skin’s surface, conserving heat.
The Effects of Caffeine on the Body
Now that we understand how the body regulates its temperature, let’s look at the effects of caffeine on the body. Caffeine is a stimulant that can affect the body’s thermoregulation mechanisms.
Increased Metabolism
Caffeine can increase the body’s metabolic rate, which can lead to an increase in body temperature. This is because the body is burning more energy, producing more heat as a byproduct.
Increased Heart Rate and Blood Pressure
Caffeine can also increase heart rate and blood pressure, which can lead to increased blood flow to the skin’s surface. This can cause the body to lose heat more quickly, potentially cooling it down.
The Effects of Hot Coffee on the Body
Now that we understand the effects of caffeine on the body, let’s look at the effects of hot coffee specifically.
Initial Heat Shock
When you drink hot coffee, your body experiences an initial heat shock. The hot liquid can raise the temperature of the mouth, throat, and digestive tract, which can cause a temporary increase in body temperature.
Increased Sweating
However, as the body tries to cool down the hot liquid, it can cause an increase in sweating. This is because the body is trying to evaporate the heat from the hot coffee, which can lead to a cooling effect.
Thermoregulatory Response
The body’s thermoregulatory response to hot coffee is complex. While the initial heat shock can cause a temporary increase in body temperature, the body’s cooling mechanisms can kick in to counteract this effect. The increased sweating and vasodilation can help to cool the body down, potentially offsetting the initial heat shock.
Does Drinking Hot Coffee Make You Hotter?
So, does drinking hot coffee make you hotter? The answer is not a simple yes or no. While the initial heat shock from drinking hot coffee can cause a temporary increase in body temperature, the body’s cooling mechanisms can kick in to counteract this effect.
In fact, studies have shown that drinking hot coffee can actually have a cooling effect on the body. A study published in the International Journal of Sports Nutrition and Exercise Metabolism found that drinking hot coffee increased sweat rate and improved exercise performance in athletes.
Another study published in the European Journal of Applied Physiology found that drinking hot coffee improved thermoregulation and reduced heat stress in individuals working in hot environments.
Conclusion
In conclusion, the relationship between drinking hot coffee and body temperature is complex. While the initial heat shock from drinking hot coffee can cause a temporary increase in body temperature, the body’s cooling mechanisms can kick in to counteract this effect.
So, the next time you’re tempted to reach for a cold drink on a hot summer day, consider grabbing a hot cup of coffee instead. Not only can it provide a much-needed caffeine boost, but it may also help to cool you down.

It’s worth noting that individual results may vary, and the effects of hot coffee on body temperature can depend on various factors, such as the temperature of the coffee, the amount of caffeine consumed, and individual tolerance to heat and caffeine.
In any case, the next time you’re feeling hot and bothered, don’t be afraid to reach for a hot cup of coffee. It may just be the cooling drink you need.
Does drinking hot coffee make you hotter?
Drinking hot coffee can make you feel hotter, but it’s not because the coffee itself is raising your body temperature. When you drink hot coffee, the heat from the liquid is transferred to your tongue, the roof of your mouth, and the back of your throat. This can create a sensation of heat that spreads throughout your body.
However, this sensation is temporary and doesn’t actually increase your body temperature. In fact, the caffeine in coffee can have a cooling effect on the body by increasing blood flow to the skin and causing you to sweat. So, while drinking hot coffee may make you feel hotter, it’s not actually raising your body temperature.
How does the body regulate temperature?
The body regulates temperature through a process called thermoregulation. This involves the hypothalamus, a small gland in the brain that acts as the body’s thermostat. The hypothalamus monitors the body’s temperature and sends signals to the sweat glands, blood vessels, and other organs to either heat up or cool down the body.
When the body gets too hot, the hypothalamus sends signals to the sweat glands to produce sweat, which helps to cool the body down through evaporation. At the same time, the blood vessels near the surface of the skin dilate, allowing more blood to flow to the skin and release heat. This process helps to regulate the body’s temperature and keep it within a narrow range.
Can drinking hot coffee affect your body’s ability to regulate temperature?
Drinking hot coffee can affect your body’s ability to regulate temperature, but only temporarily. The heat from the coffee can overwhelm the body’s thermoregulation system, making it harder for the body to cool down. However, this effect is short-lived and the body is able to recover quickly.
In fact, the caffeine in coffee can actually help the body to regulate temperature more efficiently. Caffeine is a stimulant that increases blood flow to the skin and causes the body to sweat more. This can help the body to cool down more quickly, especially in hot environments.
Is it better to drink hot or cold coffee in hot weather?
In hot weather, it’s generally better to drink cold coffee rather than hot coffee. Cold coffee is less likely to overwhelm the body’s thermoregulation system and can actually help to cool the body down. The caffeine in cold coffee can also help to increase blood flow to the skin and cause the body to sweat more, which can help to cool the body down.
However, if you prefer hot coffee, it’s not necessary to switch to cold coffee entirely. You can still drink hot coffee in hot weather, just be sure to drink it in moderation and take regular breaks to cool down. It’s also a good idea to drink plenty of water to stay hydrated.
Can drinking hot coffee cause heat-related illnesses?
Drinking hot coffee is unlikely to cause heat-related illnesses, such as heat exhaustion or heat stroke. However, it can contribute to dehydration, especially if you’re not drinking enough water. Dehydration can increase the risk of heat-related illnesses, especially in hot weather.
To avoid dehydration, it’s a good idea to drink plenty of water throughout the day, especially when drinking hot coffee. You can also try drinking cold coffee or other cold beverages to help stay cool and hydrated.
How can you stay cool while drinking hot coffee?
There are several ways to stay cool while drinking hot coffee. One way is to drink it slowly and in moderation, taking regular breaks to cool down. You can also try drinking it in a cool, well-ventilated area, or using a fan or air conditioner to stay cool.
Another way to stay cool is to drink cold beverages, such as water or cold coffee, in addition to hot coffee. This can help to balance out the heat from the hot coffee and keep your body temperature regulated.
Are there any health benefits to drinking hot coffee?
Yes, there are several health benefits to drinking hot coffee. The caffeine in coffee can help to increase alertness and energy, and may also have antioxidant and anti-inflammatory effects. Additionally, moderate coffee consumption has been linked to a lower risk of certain diseases, such as type 2 diabetes and Parkinson’s disease.
However, it’s worth noting that these benefits are generally associated with moderate coffee consumption, defined as 3-4 cups per day. Excessive coffee consumption can have negative effects, such as increasing heart rate and blood pressure, and disrupting sleep patterns.
