Part 7/9:
The insights Heather shares about biphasic sleep challenge modern perspectives on insomnia and wakefulness during the night. Instead of viewing these interruptions as problems, historical context suggests they could very well be a natural and ingrained part of our biological rhythms.
Recent studies, including those by sleep scientist Thomas Ver, have demonstrated that recreating pre-industrial conditions can bring about a resurgence of biphasic sleep patterns among participants. This suggests the practice is deeply embedded in our physiology—potentially waiting to emerge once again if circumstances allow.
