A sleep researcher warns that drinking coffee immediately after waking may not be the best idea due to dehydration and advises waiting 90 minutes after waking before having the first cup.
In a recent podcast, sleep researcher Dr. Michael Breus discussed the best timing for drinking coffee in the morning and how it relates to an individual's chronotype, which is their natural sleep-wake cycle. He cautioned that consuming caffeine right after waking is likely not the best practice, as it can exacerbate dehydration. Sleep naturally leads to a loss of fluids, and Dr. Breus highlighted that coffee acts as a diuretic, further contributing to fluid loss when consumed first thing in the morning.
Dr. Breus advised that to minimize the negative effects of coffee on hydration, individuals should first drink water upon waking to replenish lost fluids before enjoying their caffeine fix. He recommended that the optimal time to consume the first cup of coffee is approximately 90 minutes after waking, when the body's hormone levels, particularly adrenaline and cortisol, have reached their peak. These hormones help individuals wake up fully and transition out of sleep, setting a more favorable context for caffeine intake.
The findings emphasize the importance of timing concerning coffee consumption and hydration, encouraging listeners to rethink their morning routines. Dr. Breus's insights may not only improve their coffee enjoyment but could also have implications for overall health and well-being, particularly regarding hydration and sleep management.
