A Columbia University study quietly confirms what exhausted bodies have long been trying to say: sleep is not a luxury but a metabolic necessity. Over six weeks, adults who trimmed just ninety minutes from their nightly rest gained roughly a pound and widened at the waist — without eating more or moving less in any measurable way. The finding lands in a culture that has long treated sleeplessness as ambition, and asks whether the true cost of that bargain is being written not in productivity, but in flesh.
