Problem it solves

Individuals with non-traditional schedules

Not ideal for

Those with traditional 9-to-5 schedules

Overview

Why this framework exists

The Biphasic Sleep Framework involves sleeping in two phases, with a period of wakefulness in between. This can be achieved through various methods, including the Siesta-like notion of a long bout at night and a short bout during the day. However, Dr. Walker notes that there is limited evidence to support the idea that humans are naturally designed to sleep in this way.
