The Bear Chronotype
The Solar Rhythm (50% of population)

Frequently Asked Questions about Bears
Can a Bear shift to a Wolf schedule?▼
Bears follow the sun. Shifting to an evening Wolf schedule long-term is highly disruptive for Bears, leading to severe mid-afternoon energy crashes and accumulated sleep debt.
How many hours of sleep does a Bear need?▼
Bears have a high sleep drive and typically require a full 8 hours of sleep to stay alert. Restricting sleep to 6 hours will trigger severe cognitive declines by day three.
