Circadian Reboot - E9 Dr. Sara Pugh Discusses the Role that Light Plays on Cholesterol and Health

In this episode of Circadian Reboot, Pam Killeen interviews Sarah Pugh, a seasoned scientist with a background in genetics, biochemistry, and biophysics. They discuss the intricate relationship between cholesterol, statins, and light exposure, emphasizing the often misunderstood role of cholesterol in the body. Sarah explains how artificial light affects blood sugar levels and overall health, and introduces the concept of deuterium and its impact on energy production. The conversation also covers practical health strategies such as cold thermogenesis, fasting, and the importance of grounding. Sarah shares insights on overcoming the fear of sunlight and the detrimental effects of modern environments on health. The episode concludes with a discussion on practical circadian living and Sarah’s future projects.

Cholesterol is essential for hormone production and is often misunderstood.
Sunlight plays a crucial role in regulating heart health and calcium levels.
Artificial blue light can raise blood sugar and cortisol levels.
Deuterium affects mitochondrial function and energy production.
Cold thermogenesis can improve insulin sensitivity and overall health.
Fasting can help with autophagy and gut health but should be approached carefully.
Grounding connects us to the earth and can enhance health.
Modern environments, including schools, often hinder our health due to poor lighting.
Practical circadian living involves aligning daily routines with natural light cycles.
It’s important to be kind to oneself in the journey towards better health.

“You can use sunlight to correct all of these situations.”
“Cholesterol is an anti-inflammatory agent.”
“The sun is this very important healing thing.”
