If you have a habit of drinking coffee on an empty stomach, beware!

Coffee is one of the drinks that is lovingly consumed with its smell and taste. Those who want to start the day fit and vital generally prefer to drink coffee immediately after waking up. However, drinking coffee on an empty stomach can have a negative impact on your body’s health. Recent research has revealed all the facts about drinking coffee on an empty stomach.

Gastric acid

Drinking coffee on an empty stomach can cause heartburn. For those who don’t know, heartburn refers to a burning pain or discomfort in the upper part of the chest and in the middle of the chest. It can be caused by several factors. Coffee starts the production of stomach acid, which will lower the pH of your stomach. If you consume your coffee with milk or if you already have food in your stomach, it won’t get any less or less. While a slightly lower pH may not be a problem for the stomach lining, it can be a problem for the lining of your esophagus, which is more susceptible to acid damage.


Drinking coffee right after waking up can do more harm than good. According to research, your body’s production of cortisol is at one of its three-day peaks in the hour after you wake up. Cortisol helps increase alertness. For those who don’t know yet, the caffeine in your coffee also raises your cortisol levels. If you drink caffeinated coffee now at a time when your body is already at the peak of cortisol production, it will teach your body to produce less cortisol. It can also contribute to developing a tolerance to coffee, meaning you need to drink higher amounts of caffeine (coffee) to achieve the same level of alertness. Research shows that drinking coffee along with a balanced diet helps stimulate the colon and increase bowel regularity. But if you drink coffee on an empty stomach with no food in your stomach, your gut may be working harder than you want it to.


Experts recommend having your coffee or tea at least an hour after waking up. Instead of regular coffee, you prefer to drink it with milk to reduce the effect on your esophagus. If you feel sluggish right after waking up, make sure you get enough sleep. Thirst can also be responsible for this feeling, and drinking water after waking up can help you feel more energized.
