Many start their day with a habitual cup of coffee, but experts recommend waiting at least an hour after waking. This helps the body wake up naturally and reduces the negative impact of caffeine on sleep.
Cortisol and Morning Alertness
In the morning, cortisol levels — the stress hormone — peak. It naturally increases alertness. If you drink coffee during this period, the effect of alertness will be minimal, and over time, tolerance to caffeine may develop.
Impact on Sleep and Adenosine
Caffeine blocks the action of adenosine — a substance that causes drowsiness as fatigue builds up. Early coffee consumption disrupts this process, making it harder to fall asleep in the evening.
Alternatives to Morning Coffee
To wake up without harming the body, experts recommend:
- turmeric latte,
- herbal tea (mint or ginger).
These drinks help to invigorate without disrupting the natural balance of hormones and sleep cycles.
