Research at the University of Colorado at Boulder suggests that escaping artificial light even for just a couple of days can help boost melatonin secretion. 

“These studies suggest that our internal clock responds strongly and quite rapidly to the natural light-dark cycle,” said lead author and CU Boulder integrative physiology professor Kenneth Wright, who believes his findings could help light-based approaches for boosting work performance, quelling seasonal depression and circadian sleep-wake disorders. “Living in our modern environments can significantly delay our circadian timing and late circadian timing is associated with many health consequences. But as little as a weekend camping trip can reset it.”
