Does drinking coffee on a rest day hinder recovery and muscle development?

Drinking coffee, especially later in the day, can hinder recovery by affecting sleep quality, which is crucial for muscle development and overall health. Andrew Huberman points out that caffeine consumed even 8 to 10 hours before bedtime can disrupt sleep architecture, impacting recovery processes that occur during sleep 1. Therefore, it's important to manage caffeine intake on rest days to ensure it doesn't interfere with sleep, which is essential for effective muscle recovery and growth.
