Cemetery shifts earn their name for a reason. Individuals working night shifts face heightened health risks, including heart disease, type 2 diabetes, and depression. The World Health Organization has identified shift work as a potential carcinogen, given the increased likelihood of cancer.

While the rest of us are asleep, these night workers often go unnoticed, yet their efforts are vital to the medical and emergency services on which we rely. Though we depend on them for our very survival, the irony lies in how their work impacts their own health.

This situation could evolve with the advent of a test that accurately measures one’s internal biological clock in relation to external time (see “How innovative new tests can unleash the power of your body clock”). Such advancements in medicine promise to benefit a larger population.

Research indicates that many frequently used medications affect the body’s system, which operates on a 24-hour cycle, and are more effective when administered in harmony with this rhythm. Surgeries and vaccinations also yield better results at specific times of the day. Initial strategies often rely on standardized biological clocks, but for those whose circadian rhythms are misaligned, this approach may prove ineffective or even detrimental. This is where the new tests come into play.

Fortunately, these tests are expected to become more affordable and widely accessible. However, there is a concern that they could be misused by those anxiously trying to optimize their health, perhaps alongside other fitness metrics like step counts (refer to page 16).

The genuine potential lies in using these tests to gain insights into the biological processes of those in challenging situations, ensuring that in the future, the effects of nighttime work and improved strategies for managing shift patterns are addressed. One day, your biological clock may finally align with the external clock.

This could mitigate the health repercussions associated with night shifts and provide these employees with a chance to revitalize their lives. Employers must recognize this opportunity.
