The New Science of the Body Clock: How Separate Beds Boost Relationships, Sleep Supplements, and Reducing Night-Time Peeing
Prof. Russell Foster on circadian neuroscience: why body clock disruption causes disease, the truth about sleep supplements, why separate beds may improve both sleep and relationships, and the surprising link between sleep timing and mental health.

Highlights
•
Circadian disruption causes disease — not just through poor sleep, but through metabolic dysregulation
Foster: every organ in the body has its own circadian clock. When these clocks are desynchronized (by shift work, jet lag, irregular schedules, or light pollution), the metabolic consequences include insulin resistance, obesity, cardiovascular disease, and depression.•
Most sleep supplements don't work — but light management is free and highly effective
Foster: melatonin supplements are oversold, valerian has no evidence, and magnesium's sleep effects are modest at best. The most effective sleep intervention is free: managing light exposure — bright light in morning, dim light in evening.Was this useful?
