Engaging in the morning ritual of sipping that cherished cup of coffee, you might not realize the delicate dance between caffeine and your body’s natural chemistry.
Believe it or not, that cup of coffee first thing in the morning could negatively impact your body’s cortisol levels. As we wake up, our cortisol — also known as a stress hormone — naturally rises, preparing our digestive and absorptive organs for the processes to begin.
Cortisol is primarily produced by the adrenal glands and plays a vital role in your daily functioning. It helps regulate metabolism, blood sugar levels, and immune response, adapting your body’s energy levels and stress responses.
If we start the morning with caffeine as the first intake, two things are likely to happen:
- If you drink coffee on an empty stomach, your blood sugar will spike because caffeine enters the system more quickly without food to buffer it.
- Additional cortisol is produced to compensate for caffeine’s effects, which, over time, contribute to insulin resistance and abdominal adiposity.
The relationship between coffee and cortisol is complex, with different studies suggesting varied outcomes based on when and how coffee is consumed. Consuming coffee during peak cortisol times, like early morning, may enhance the body’s stress response, which could ultimately lead to increased caffeine dependency, prompting you to reach for more cups throughout the day for sustained energy.
However, timing your coffee consumption to after peak cortisol levels might optimize caffeine’s effects. By following caffeine intake recommendations, you could help ensure a more balanced daily energy profile, potentially mitigating unnecessary cortisol spikes. It would be beneficial to wait an hour or two before your first cup, so the body is naturally warm and the caffeine can enhance the benefits of waking the body and aligning with your circadian rhythm.
For many, this may be a non-negotiable or a challenging behavior to modify, and if that is the case, here are my recommendations:
- Try to have at least 8oz of water before coffee.
- Consume foods containing protein and fiber to help slow glucose absorption.
- If you haven’t slept well, consider an alternative to coffee, such as an herbal tea.
