Circadian Disruption and Cancer: What’s the Link?
-
Circadian rhythms are 24-hour biological cycles that regulate sleep, metabolism, hormone production, and other essential functions.
-
These rhythms are controlled by a "biological clock" in the brain (specifically, the suprachiasmatic nucleus in the hypothalamus) and are influenced by light exposure, especially sunlight.
🧬 How Disruption Occurs:
-
Shift work, jet lag, irregular sleep schedules, and excessive exposure to artificial light at night can all disrupt circadian rhythms.
-
This disruption affects the timing of cell repair, DNA replication, and hormone release, which can potentially contribute to the development and progression of cancer.
🔬 Evidence Linking Circadian Disruption to Cancer:
-
Studies show increased cancer risk (especially breast, prostate, and colorectal cancers) in long-term night-shift workers.
-
The World Health Organization (WHO) has classified night shift work as a probable carcinogen.
-
Melatonin suppression (caused by nighttime light exposure) may play a role, since melatonin has antioxidant and anti-cancer properties.
💡 Potential Solutions and Preventative Measures:
-
Limiting light exposure at night (especially blue light).
-
Maintaining regular sleep-wake cycles.
-
Designing work schedules to reduce chronic circadian disruption.
-
Research into chronotherapy — timing cancer treatments to circadian rhythms to improve effectiveness and reduce side effects.
