Why We Should End Daylight Saving Time with Permanent Standard Time
In March of 2022, the US Congress made an unprecedented move. The Senate unanimously approved Sen. Marco Rubio’s “Sunshine Protection Act” — a bill intended to end the confusing, chaotic, twice-yearly practice of clock changes across the country. It would do so by extension of Daylight Saving Time (DST) permanently into winter. (The equivalent of […]
Eating at the right time of day matters!
We know that what we eat matters, but how about when we eat? As the adage goes, timing is everything. This certainly applies to eating. By aligning meals with our internal circadian rhythms — the system that orchestrates sleep and wake times, hormone production, metabolic processes, and more — data strongly suggest that we can […]
The long-term evolution of light sensitivity from single-cell organisms to humans: What we are missing now
Evolutionary biologists assume that life arose in the earth’s oceans about 3.5 billion years ago. About a billion years later, the conditions for life changed decisively: sunlight was used for the first time by single-cell organisms for photosynthesis. That would be approximately one trillion sunrises to which life on earth has been exposed to. The […]
Optimizing physical performance: it’s all about timing
When we watch sports games or races, such as at the Olympics, it becomes clear that the difference between finishing first or second can come down to a matter of milliseconds. With such miniscule differences, every aspect of physical performance has to be optimized. The circadian system — our biological clock — regulates body processes […]
How We Keep Our Circadian Rhythms from Drifting
Imagine sitting out in space watching the earth gently rotate eastward on its axis, providing daily sunsets and dawns to all us 7.6 billion earthlings. In the sunlit surface of earth, nearly everybody is awake, and on the dark backside, everyone is asleep – or trying to sleep – except for the nightshift workers (who […]
Circadian Misalignment: A Biological Basis for Mood Vulnerability in Shift Work
Depression has significant economic impact: According to the World Health Organization, the estimated cost to the global economy is US$1 trillion per year in lost productivity. Shift work is prevalent across the world — approximately 15-20% of employees perform shift work in industrialized countries. With so many people engaged in shift work, it becomes important […]
We Are Clockworks
Fifty years ago, circadian rhythm research underwent a monumental breakthrough with the discovery of a tiny area of the brain, the suprachiasmatic nuclei (SCN), the site of the biological clock in mammals. This master pacemaker is synchronized to the day-night cycle mainly by light transduced by special photoreceptors in the eye, and the SCN in […]
