I've been tracking my sleep with a wearable for six months, and the data suggests that sleeping 7-9 hours consistently correlates with better focus and mood. Yet I still meet people who proudly brag about surviving on 5 hours. Could our culture's glorification of sleep deprivation be shortening our lives while we chase productivity? Studies on sleep and longevity are still inconclusive, but the evidence linking chronic short sleep to heart disease and cognitive decline keeps growing. Should we treat 7-8 hours of sleep as a non-negotiable health requirement rather than a luxury for the lazy?
