For many of us, the day doesn’t truly begin until we’ve had our morning coffee or some other caffeinated drink. But have you ever considered that you might be drinking your coffee at the wrong time?
Our bodies operate on an internal schedule known as the circadian rhythm. This biological clock influences various bodily functions, including our alertness levels throughout the day. A key player in this process is cortisol, a hormone often linked to stress because it’s released in high amounts during stressful situations. However, cortisol also plays a crucial role in keeping us alert.
Interestingly, cortisol levels naturally peak between 8:00 and 9:00 a.m., providing a natural boost to help us wake up. While it might seem logical to pair this natural alertness with caffeine, research suggests otherwise.
Studies indicate that consuming caffeine during peak cortisol production can actually reduce its effectiveness. This can lead to increased caffeine tolerance, meaning you’ll need more caffeine over time to achieve the same level of alertness. For a deeper dive into caffeine addiction and tolerance, you might want to explore resources like “Your Brain on Coffee.”
To maximize the benefits of caffeine, it’s advisable to enjoy your coffee after the cortisol peak, ideally after 9:00 a.m. Additionally, cortisol levels also rise between noon and 1:00 p.m. and again from 5:30 to 6:30 p.m. Therefore, it’s best to avoid caffeine during these times as well.
Your circadian rhythm is primarily influenced by sunlight, which means your sleep schedule doesn’t significantly alter these cortisol peaks. So, whether you’re an early riser or a night owl, the timing of your coffee matters. Upon waking, cortisol levels increase by about 50%, regardless of the hour. Therefore, it’s recommended to wait at least an hour after waking before having your first cup of coffee to allow your body to naturally adjust.

Many of us wake up with one thing on our mind: coffee, or at least some form of caffeinated beverage to get our day started. But what if I told you that you might be drinking your coffee incorrectly?
We all have an internal biological clock called the circadian rhythm, which regulates many processes throughout our body, including our levels of alertness during the day. This clock controls the release of a hormone called cortisol, often referred to as the stress hormone because it’s secreted in high levels during our body’s fight or flight response. Cortisol is also related to our level of alertness throughout the day, and it just so happens that between 8:00 and 9:00 a.m., cortisol levels peak. This means that our body has a natural mechanism to wake us up.
While you may think that caffeine can complement this mechanism, scientists have found that consuming coffee or energy drinks during peak cortisol production can actually diminish the caffeine’s effect and lead to a greater tolerance over time. This means you may feel less of a buzz and need even more caffeine to stay awake in the future. We break down caffeine addiction and tolerance in a previous video titled “Your Brain on Coffee,” which you can check out.
For this reason, drinking coffee after your cortisol surge at 9:00 a.m. is probably best. Scientists have also found other times when cortisol peaks, such as between noon and 1:00 p.m. and 5:30 and 6:30 p.m. This means it’s generally best to drink your coffee outside of these times.
These cortisol spikes and your circadian rhythm are most strongly regulated by sunlight, meaning your sleep schedule doesn’t play as significant a role. So, what if you wake up extremely early or really late? Should you drink coffee right away? Well, scientists have found that cortisol levels do indeed increase about 50% right after you wake up, regardless of the time. Science suggests waiting at least an hour before having your cup of coffee, as your body will be optimally ready to go.

Caffeine – A natural stimulant most commonly found in coffee, tea, and various energy drinks, known for its ability to temporarily ward off drowsiness and restore alertness. – Caffeine consumption can lead to increased alertness by blocking adenosine receptors in the brain.
Cortisol – A steroid hormone produced by the adrenal glands, often released in response to stress and low blood-glucose concentration. – Elevated cortisol levels can affect various bodily functions, including metabolism and immune response.
Circadian – Relating to biological processes that display an endogenous, entrainable oscillation of about 24 hours. – Circadian rhythms are crucial for regulating sleep-wake cycles and other physiological processes in humans.
Rhythm – A strong, regular, repeated pattern of movement or sound, often used to describe the natural cycles of biological processes. – The circadian rhythm is essential for maintaining the body’s internal clock and synchronizing it with the environment.
Alertness – The state of being awake and aware of one’s surroundings, often influenced by various biological and environmental factors. – Maintaining alertness during lectures can be challenging without adequate sleep and proper nutrition.
Tolerance – The diminishing effect of a drug resulting from repeated administration at a given dose, requiring an increase in dosage to achieve the desired effect. – Regular caffeine consumption can lead to tolerance, necessitating higher doses to achieve the same level of alertness.
Sunlight – The natural light of the sun, which plays a crucial role in regulating biological processes such as vitamin D synthesis and circadian rhythms. – Exposure to sunlight in the morning can help reset the circadian clock and improve mood and alertness.
Sleep – A naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, and inhibition of nearly all voluntary muscles. – Adequate sleep is essential for cognitive function, memory consolidation, and overall health.
Biology – The scientific study of life and living organisms, encompassing various fields such as genetics, ecology, and physiology. – Understanding the principles of biology is fundamental for advancing medical research and improving public health.
Health – The state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity. – Regular exercise, a balanced diet, and sufficient sleep are vital components of maintaining good health.
