And you've been told by many sources that getting light exposure is extremely important for your sleep rhythm and for your mental health.
Today we're diving into what modern circadian rhythm science reveals about sleep, energy, and why your lighting environment might be the single most overlooked lever for transforming your health and mood.
Joining me today is Dr. Jamie Zeitzer, a leading circadian rhythm researcher, and Lucas Tang, the co-founder of Lumos Glasses, a company rethinking how we use light to sync with our biology.
By the end of this conversation, you'll understand why light works as a conductor, orchestrating every system in the body, and why the contrast between bright days and dark nights matters far more than you think.
We'll cover the surprising connection between morning light and mood and give you practical tools that fit your life.
And before we begin, make sure you check the show notes for a special link that will take you to a download document that will give you a summary of light therapy and its applications and a breakdown of the mechanisms of circadian rhythm and light therapy.
