Deep dives
Impact of Eating Windows on Digestion and Sleep
Eating over extended periods, such as the average American's 15-hour window, places significant stress on the body's digestive process. This extended eating schedule can interfere with essential repair and restoration functions that typically occur during sleep, as the body prioritizes digestion instead. Narrow feeding windows, particularly under eight hours, have been linked to hormone disruption in women, potentially due to the additional metabolic strain during phases of their menstrual cycle. This suggests that a balance in eating patterns is crucial for maintaining not just digestive health but also overall physiological functions like sleep and hormonal balance.
