🌙 Why We Left Out Caffeine


Caffeine reduces the quality of your sleep and recovery — even hours after the effects wears off.



Caffeine taken up to 12 hours before bed can reduce sleep quality.

📖 Drake et al., 2013 – J Clin Sleep Med


It may reduce deep sleep, even if you fall asleep fine

📖 Clark & Landolt, 2017 – Neuropsychopharmacology
