Does Coffee Quench Your Thirst? (Read to Know)

Short Answer: Sipping on a cup of coffee does indeed moisten your mouth and fills up your belly. The immediate sensation satisfies your desire for fluid. It may feel like it quenched your thirst but it’s just momentarily.

This immediate and temporary satisfaction may be misleading indicators. Little did you know that after drinking a caffeinated beverage, your thirst tends to increase especially if you’re not used to the drink.

The health experts in the Harvard School of Public Health have declared water as the best thirst-quenching drink.

It’s also better to skip the sugary drinks and go easy on the milk and juice.

Even though there are plenty of options of what to drink out there, water is always the best choice. Why? It contains zero calories! And it’s as easy to find as the nearest tap.

Does coffee quench hunger?

Caffeine in coffee may reduce feelings of hunger and your desire to eat – but just for a short period. 

Caffeine tends to increase energy consumption even when you’re at rest. It is said to stimulate thermogenesis — one way your body extracts heat and energy by digesting food.

Coffee also contains plant-based chemical compounds called chlorogenic acids.

Chlorogenic acids have recently become quite popular among obesity researchers and dietary supplement manufacturers, as they are found to help decrease hunger. Therefore, it can be said that coffee may help in losing weight.

However, it is important to keep in mind that some caffeinated beverages such as specialty coffees or teas contain high amounts of calories and fat.

Also, if you are working to lose some pounds, adding milk and sugar to your coffee could set back your weight loss efforts, especially if you drink multiple cups of it in a day.

Can drinking coffee make you thirsty?

Coffee is likely to make you thirsty. This is because coffee contains high amounts of caffeine which has diuretic properties which cause you to urinate more frequently. The end result will be your body asking for more water.

If you drink coffee daily, you might appreciate its psychoactive properties which may help keep you alert.

When you take coffee or other caffeine-containing drinks, it enters your bloodstream and will affect the function of your brain and ultimately, your physical performance.

The effects of caffeine on the body can go beyond affecting just the brain functions.

Scientists have declared that caffeine is a mild diuretic. That means that it can affect your body’s water level by influencing your kidneys to urinate more. This urine-producing effect may lead to the thirst you might feel after drinking coffee.

The best way to enjoy coffee without affecting your body’s hydration system is to take it in moderation.

And as always to drink a couple of glasses of water before you have your coffee. This is especially true in the morning, as drinking water before coffee might also help in reducing its acidity.

Is coffee a diuretic?

It’s true and because of its caffeine content, coffee has a diuretic effect but it’s on the milder side.

When you have a cup of coffee, caffeine which is the main ingredient moves from your stomach to your bloodstream and liver. This is where it tends to create biochemical and metabolic changes that produce an increase in energy and the other well-known effects of caffeine.

Caffeine consumption also affects your kidneys. This is the reason why the answer to the question, “Is coffee a diuretic?” is a yes. 

Studies show that caffeine causes diuresis, commonly known as increased urination.

Your body produces urine to maintain fluid levels and remove waste. When you urinate more frequently by drinking large amounts of caffeine, your fluid levels may get off balance.

The key to keeping yourself hydrated while enjoying your cup of coffee is to drink it in small quantities and always try to replenish the fluid in your body by drinking an adequate amount of water daily.

Can I count coffee as water intake?

Coffee does count as water intake! The water in coffee can help us meet our daily fluid needs.

Even though caffeine in coffee does have a diuretic effect, it’s mild and does not offset hydration – good news for coffee lovers out there!

I wrote a separate article on this, explaining how coffee qualifies as water, and you can read it to know more.

The recommended daily intake of water is generally about eight glasses or 64 fluid ounces. If you sweat due to hot weather, by doing exercise, or if you’re sick, you are definitely required to drink more.

However, it is to be kept in mind that the best way to hydrate is always by drinking water. Though coffee contains many healthful compounds, such as antioxidants, the sugar and fat from milk and sweetened coffee drinks can lead to weight gain and other damaging health effects.

So, choose water over other caffeinated beverages!

Luckily, there is another way to keep yourself hydrated if you are not a fan of drinking water: eat your water.


You can do this by eating fruits and vegetables containing high amounts of water. They will not only cater to your hydration needs but will also provide essential vitamins to your body.

Fruits and vegetables that contain a high amount of water include:

  • Melons such as watermelon, honeydew or cantaloupe
  • Strawberries
  • Pineapple
  • Peaches
  • Oranges
  • Bell peppers
  • Broccoli
  • Celery
  • Cucumbers
  • Lettuce
  • Zucchini

Here’s how much water you should drink daily according to your weight:

Does coffee dehydrate your skin?

Though coffee is the most important part of the morning routine for many men and women, it is also true that it can contribute to causing damage to your skin.

Essentially, adequate water intake is key to healthy glowing skin. And I’m sorry to say coffee is not the best way to stay hydrated due to its caffeine content.

If you drink more than three cups of coffee daily without replenishing with water, you’re more likely to have issues with your skin due to dehydration, among other factors. These problems may include:

  • The high acidity in coffee can cause hormonal imbalance and impact the amount of oil your skin produces.
  • Coffee drinks prepared using dairy products may increase the risk of developing acne.
  • Dehydration from coffee and other caffeinated beverages may also cause skin redness or inflammation.
  • Dry skin patches can start to form around your nose and chin area.

To sum it all up

Coffee may help you feel satisfied with your desire for fluid but only for a short time. However, it may cause an increase in your thirst.

Coffee is high in caffeine which has diuretic properties and can cause you to urinate more frequently, resulting in your body requiring more water and you feeling thirsty.

Our body often uses the thirst trigger to communicate that it needs more water. When you try to quench your thirst by drinking coffee, its caffeine’s diuretic effects could flush the fluid from your body rather than replenish it. 

Water is proven to be the best way to quench your thirst. It’s calorie-free, inexpensive, contains no caffeine, and readily available. 

The amount of water you require for optimal hydration depends on many variables, including how active you are and the climate you live in. 

If you drink a sufficient amount of water every day, your moderate caffeine intake will not significantly dehydrate you.

To stay hydrated, you have to drink at least 8 cups of water per day. When you have adequately hydrated yourself, it’s safe to say that you can drink two or even three cups of coffee in a day.

However, moderate coffee intake might be best because apart from the hydration point of view, excessive coffee consumption might also be related to addiction, anxiety, cardiovascular troubles, and insomnia.
