Progress has been made in understanding how our bodies can better adjust to these disruptions, but scientists have now discovered a "reset button" that to new possibilities for treatments to get our bodies back in sync.

Our biological clocks, or circadian rhythms, run on 24 hour cycles and are dictated by changes in light. If an external factor throws this clock out of whack, be it through lack of exposure to sunlight, working late shifts or playing World of Warcraft all night, it can induce depression, changes in mood and conditions such as seasonal affective disorder.

Over the years, various research efforts have been directed at pinning down the mechanism that keeps this clock ticking, and how it might be manipulated to counter the negative health impacts. This has resulted in solutions such as LED light glasses, purpose-built glass houses and glowing pillows.
