Other researchers warn against overstating the case. Professor James Hartley of Cambridge University notes that sleep does not guarantee better decisions; it merely improves the probability of insight. “If your initial information is biased, sleeping won’t fix that,” he says. Moreover, he adds, extreme fatigue impairs decision-making, so a short nap may be more helpful than a full night of broken sleep.

Visually stunning, but the film lacks concrete solutions. It repeats well-known facts about ocean pollution without offering new insights. However, the footage of affected wildlife is genuinely moving. Other researchers warn against overstating the case
A powerful call to action. Unlike many environmental documentaries, this one focuses on economic incentives for recycling, which I found refreshing. My only criticism is the overly dramatic narration.
For centuries, people have advised those facing difficult choices to “sleep on it”. But is there scientific evidence to support this intuition? A growing body of research suggests that sleep plays a crucial role in complex decision-making, particularly when it involves integrating multiple pieces of information. Unlike many environmental documentaries
However, not all decisions benefit equally from sleep. Simple, logical choices—like whether to take an umbrella based on a weather forecast—do not require the same cognitive restructuring. Sleep seems most beneficial when decisions are “ill-structured”: when information is incomplete, contradictory, or when multiple outcomes are possible. In such cases, sleeping on a problem can help the brain to prioritise relevant over irrelevant details.
