Why the timing and type of light you receive may matter more to your health than you realize.

Most of us think about nutrition, exercise, sleep, stress management, and supplements when it comes to our health. But how often do we think about light?

In this episode of Everyday Wellness with Nurse Bev, we explore the growing science behind light exposure and its influence on human health. Far beyond helping us see, light serves as a powerful biological signal that helps regulate circadian rhythms, hormone production, metabolism, immune function, mood, cognitive performance, and sleep.

You'll learn how the body uses light to keep time, why modern lifestyles have dramatically changed our relationship with light, and what researchers are discovering about the effects of artificial light exposure, circadian disruption, and overall health.

We'll discuss:

• Why light is one of the body's most important environmental signals

• The role of circadian rhythms and the body's "master clock"

• How light influences cortisol, melatonin, sleep, and daily biological rhythms

• The connection between circadian health, metabolism, blood sugar regulation, and energy

• Why many researchers are concerned about excessive artificial light exposure at night

• The emerging science of light, mitochondrial function, and cellular energy production

• What makes natural sunlight different from artificial indoor lighting

• Practical strategies to support healthy light exposure throughout the day

Whether you're interested in improving sleep, supporting metabolic health, boosting energy, or simply learning more about how the body works, this conversation offers a fascinating look at one of the most overlooked influences on health and well-being.
