The Light of the Great Outdoors聽

American adults don鈥檛 sleep enough: On the average work night, we come up 30-90 minutes short of what our bodies need for long-term health, according to a poll by the National Sleep Foundation.

Maybe we should go camping more often.

Recent research by CU Boulder sleep experts Ellen Stothard and Kenneth Wright show that exposure to the natural light and total darkness available outdoors helps reset our internal clocks in as little as two days 鈥� a weekend camping trip. By resetting our clocks, we get a chance to establish a more satisfying sleep pattern back at home.聽

鈥淢odern 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.鈥� 鈥斅燢enneth Wright

The Camping Effect

One weekend of camping can reset our internal clocks
Two-day camping trips can jumpstart production of the sleep-regulating hormone melatonin, promoting sleep at an earlier time聽
Camping is especially effective at resetting our internal clocks because it exposes us to far more natural light than we get in the typical built environment
Our bodies respond quickly to the natural light/dark cycle
