Jet lag is more than lost sleep—it is a whole-body conflict between your internal clock and a new environment, affecting energy, concentration, mood, digestion, and physical recovery.
In The Chronos Shift, Pavel Tablas translates research in chronobiology, sleep science, neuroscience, and metabolic health into a practical guide for travellers. The book explores circadian disruption, nervous-system overload, metabolic flexibility, gut jet lag, sleep architecture, and emerging research into the molecular mechanisms that regulate the body clock.
It also examines why common remedies—including excessive caffeine, sugar, sleeping pills, and intense exercise—may temporarily conceal fatigue without restoring the body’s natural rhythm.
A clear, chronological protocol explains how to use carefully timed light exposure, meals, hydration, gentle movement, rest, and environmental cues before, during, and after a journey. Written for frequent travellers, professionals, athletes, and anyone crossing time zones, The Chronos Shift offers a structured path from exhaustion and brain fog toward clearer thinking, steadier energy, and healthier adaptation.
Pavel Tablas is an author whose work explores human energy, recovery, resilience, and the relationship between the body and mind. Drawing on research in physiology, neuroscience, metabolism, and circadian health, he transforms complex scientific ideas into accessible, practical guidance. His books examine subjects including fatigue, biological rhythms, nervous-system regulation, and sustainable performance. In The Chronos Shift, he applies this approach to jet lag, helping travellers understand their bodies and adapt more effectively across time zones.
