Coffee is a popular beverage with several health benefits, including increased energy levels, alertness, improved cognitive function, and enhanced physical performance. However, the effects of drinking coffee on an empty stomach or early in the morning have been a topic of discussion. Coffee contains caffeine, a stimulant that increases cortisol levels, which is the chemical your body releases in response to danger or stress. While cortisol naturally peaks after waking up, drinking coffee first thing in the morning can further increase these levels, potentially causing a person to feel more wired or anxious. Some studies have shown that daily caffeine intake may reduce this cortisol response over time, while others suggest that the increase in cortisol levels is temporary and unlikely to lead to long-term health complications.

What You'll Learn
Coffee first thing in the morning increases cortisol levels
The caffeine in coffee attaches to adenosine receptors, found throughout the body. Adenosine levels are lowest when you wake up but build throughout the day, promoting sleepiness. Caffeine blocks these receptors, keeping you awake and alert. It also impacts how nutrients are transported through your body, promoting energy production.
Caffeine increases cortisol secretion in people at rest or undergoing mental stress. It activates the stress axis, elevating glucocorticoid and catecholamine output along with increases in blood pressure. However, the effects of caffeine on cortisol may be reduced by pharmacologic tolerance in proportion to a person's level of daily consumption.
While coffee has several health benefits, such as improved alertness, cognitive function, and physical performance, excessive cortisol levels can have negative consequences. Chronically high cortisol levels can lead to inflammation and cell damage, increasing the risk for weight gain, diabetes, heart problems, and other health concerns.
Some people may welcome the extra jolt of energy from increased cortisol production, while others may feel more anxious, jittery, or irritable. The stimulating effects of coffee first thing in the morning can rev up your cortisol production, but it may be wiser to wait until later in the morning to drink coffee, as cortisol levels naturally dip between 9:30 a.m. and 11 a.m.

Drinking coffee on an empty stomach may increase cortisol
Coffee is a popular beverage, often enjoyed as a morning pick-me-up due to its ability to increase energy levels, alertness, cognitive function, and physical performance. However, the timing of coffee consumption has been a subject of interest, particularly regarding its impact on cortisol levels when consumed on an empty stomach.
Several studies have examined the impact of caffeine intake on cortisol secretion. One study found that caffeine intake increased cortisol secretion in individuals at rest or undergoing mental stress. Another study compared the effects of caffeine intake at different times of the day and found that caffeine challenge doses caused a robust increase in cortisol levels. These findings suggest that caffeine does influence cortisol secretion.
While coffee may temporarily increase cortisol levels, it is important to note that the negative effects of chronically high cortisol are more likely to result from health disorders like Cushing's syndrome rather than coffee intake. Additionally, the impact of coffee on cortisol levels seems to vary among individuals, with regular coffee drinkers experiencing lower cortisol production in response to coffee.
To summarize, drinking coffee on an empty stomach may lead to a temporary increase in cortisol levels. However, this does not necessarily lead to long-term health complications, and the overall impact depends on individual factors and the frequency of coffee consumption.

Caffeine increases cortisol secretion in people at rest
Coffee is a popular beverage, with consumption levels coming second only to water in some countries. The caffeine content in coffee helps increase energy levels, alertness, improve cognitive function, and enhance physical performance. However, the stimulating effects of caffeinated coffee first thing in the morning can increase cortisol production in the body.
Cortisol, often referred to as the stress hormone, is a chemical released by the body in response to danger or stressful situations. Cortisol levels naturally peak around the time one wakes up, decline over the day, and peak again during the early phases of sleep. Coffee stimulates cortisol production, and drinking it first thing in the morning, when cortisol levels are already high, can lead to increased cortisol secretion.
Several studies have examined the effect of caffeine intake on cortisol responses. One study found that caffeine challenge doses caused a significant increase in cortisol levels across the test day, indicating that caffeine does indeed stimulate cortisol secretion. Another study specifically looked at caffeine stimulation of cortisol secretion across waking hours and found that caffeine intake during times of stress may contribute to higher blood pressure and stress responses.
While caffeine can increase cortisol secretion, it is important to note that the impact may vary depending on individual sensitivity to caffeine and other factors. Additionally, the negative effects of chronically high cortisol levels are more likely to result from health disorders rather than coffee intake. Regular coffee intake can also lead to a decrease in cortisol response over time as the body adapts. Therefore, while caffeine does increase cortisol secretion in people at rest, the overall impact on an individual's health may depend on various factors and their overall caffeine consumption habits.

Caffeine increases cortisol secretion during stress
Drinking coffee first thing in the morning can increase cortisol levels, which may make you feel more wired. Cortisol, also known as the stress hormone, is a chemical your body releases in response to danger. While your morning may not be dangerous, your body still releases cortisol after waking up to help you become more alert and aware of your surroundings.
Caffeine increases cortisol secretion in people at rest or undergoing mental stress. It is not known whether tolerance to this response develops with daily caffeine intake. However, one study found that after 5 days of caffeine intake at 300 mg/day and 600 mg/day, the cortisol response to the initial 9:00 AM caffeine dose was abolished.
Caffeine also activates the stress axis, elevating glucocorticoid and catecholamine output along with increases in blood pressure. As such, caffeine intake during times of stress may contribute to the duration and magnitude of blood pressure and stress endocrine responses. However, it is unclear whether caffeine's effects are reduced by pharmacologic tolerance in proportion to a person's level of daily consumption.
Chronically high cortisol levels brought on by stress, too much caffeine, or other factors can lead to inflammation that causes cell damage. When your cortisol levels stay elevated, you are at an increased risk for weight gain, diabetes, heart problems, and other health concerns.

Coffee may cause a temporary rise in cortisol
Coffee is a popular beverage, second only to water in some countries. Its consumption is largely due to its stimulating effects, which can help people feel less tired and more alert, improving mood, brain function, and exercise performance. However, the stimulating effects of coffee, particularly when consumed first thing in the morning, can cause a temporary rise in cortisol levels.
Cortisol, often referred to as the "stress hormone," is produced by the adrenal glands and plays a role in regulating metabolism, blood pressure, and blood sugar levels. While cortisol naturally peaks in the morning to promote alertness, coffee's caffeine content can further increase its production. This additional boost may be welcomed by some but can also lead to feelings of anxiety, jitteriness, or irritability in others.
Research has shown that caffeine increases cortisol secretion, particularly during rest or mental stress. A study conducted on men and women found that caffeine intake caused a robust increase in cortisol levels, especially when coupled with mental stress. However, it's important to note that the response to caffeine varies across individuals, with factors like genetics and metabolism playing a role.
While chronically high cortisol levels can lead to health issues, the temporary rise in cortisol from coffee is unlikely to cause long-term complications. Regular coffee intake may even lead to lower cortisol responses as the body adapts to produce less of the hormone on its own. Nonetheless, some experts recommend waiting about an hour or two after waking up to drink coffee, allowing the body to utilise its natural energy resources first.
In summary, while coffee may cause a temporary increase in cortisol levels, this effect is typically mild and short-lived. The benefits of coffee, such as improved energy, alertness, and cognitive function, often outweigh this minor side effect for most people. However, it's always a good idea to be mindful of your body's unique response to caffeine and adjust your coffee consumption accordingly.
