Humans on the Verge of Hibernation: A Bear-Inspired Path to Longer Torpor
Scientists say humans might achieve a bear-like torpor by mimicking natural hibernation, a concept gaining attention for its potential in long-duration space travel and medical care. While controlled hypothermia already lowers metabolic needs in medical settings, it is pharmacologically intensive and not a long-term solution. Big questions remain about brain safety, physiology, and ethics, and no method has yet produced reversible, long-term human torpor. Research spans identifying neural and hormonal pathways, with space agencies exploring artificial stasis as a future capability for astronauts, but practical implementation is still unresolved.
