Circadian disruption and breast cancer.

It’s a wordy title and only part of the full-title of the research paper:  “Artificial lighting in the industrialized world: circadian disruption and breast cancer.”


This paper (published in 2006) was one of the early articles that started to explore the relationship between industrialisation – specifically our ability to have light after sundown – and our health.


In summary this paper finds (in its typically science-rich language):  “maintenance of a solar day-aligned circadian rhythm in endogenous melatonin and in clock gene expression by exposure to a bright day and a dark night, may be a worthy goal.”


In short, get up when the sun gets up – stay in light during the day.  Then dim the lights after sundown.


If you don’t have access to good quality daylight during the day, we recommend using a full-spectrum light. We, or any of our partners worldwide, would happy to help you choose the right bulb for you. Shop now or ask a question
