Does melatonin do anything? (video)
Melatonin is a widely used supplement. Many people turn to the hormone hoping it will improve their sleep, but do claims of its efficacy have any merit? Clinical evidence suggests that the benefits of melatonin are modest, and it may not help everyone. And there's little to stop supplement makers from selling you snake oil. Reactions explains the chemistry of this popular sleep aid. (2018-05-10)

Moving light-dark exposure could reduce disruption faced by night shift workers
New research published in The Journal of Physiology shows that our brain clock can be shifted by light exposure, potentially to align it with night shift patterns. It highlights that a 'one size fits all' approach to managing sleep disruption in shift workers may not be appropriate. A personalized approach, with light-dark exposure scheduled and taking into account whether someone is a 'morning' or 'evening' person, could reduce shift workers' risk of health problems. (2018-03-27)

A new study from University of Colorado Boulder found that preschoolers exposed to bright light at bedtime had an 88 percent reduction in melatonin levels. Anatomical differences in their young eyes may make them more vulnerable to adverse impacts of bright light, the researchers say. (2018-03-05)

Could melatonin be the key to healthy aging?
A new British Journal of Pharmacology review highlights the role of melatonin -- a hormone that is produced at night -- in regulating sleep and the body's biological, or circadian, clock.

Our muscles measure the time of day
Biological clocks are ticking everywhere throughout our body, and a 'master clock' in the brain synchronizes all the subsidiary ones in various organs. An international team of researchers led by the University of Geneva, Switzerland, and supported by the SNSF, has found that such a circadian clock is at work in our muscles. Their research shows that perturbations of this machinery might be important for type 2 diabetes development. (2017-10-02)

(2017-06-12)

Delayed meal times reset body clocks
The human body runs according to a roughly 24-hour cycle, controlled by a 'master' clock in the brain and peripheral clocks in other parts of the body that are synchronized according to external cues, including light. Now, researchers reporting in Current Biology on June 1 have found that at least one of those clocks can also be reset based on what time a person eats breakfast, lunch, and dinner. (2017-06-01)

Athletes often have to compete late in the evening, when they are no longer able to perform at their best. As reported in the journal Frontiers in Physiology, however, researchers from the University of Basel have shown that athletes who are exposed to blue light before competing can significantly increase their performance in the final spurt. The blue light had no impact on the athletes' maximum performance. (2017-05-19)
