How can Bedouins drink so much coffee before bed without affecting their sleep?

Traditional Bedouin coffee consumption is a significant cultural ritual in Saudi Arabian desert communities, but it raises questions about sleep impacts. While the travel companion in the clip expresses concern about caffeine affecting their ability to sleep, noting they personally would struggle with this practice, it highlights a cultural difference. Bedouins have likely developed a tolerance to caffeine through generations of regular consumption, allowing them to maintain this important social custom without disrupting their sleep patterns—an adaptation that showcases how deeply embedded coffee rituals are in their nomadic lifestyle.
