398: Am I Not Getting Enough Sunlight? Key Symptoms That Affect Sleep, Energy, and Overall Health

Dr. Steven Gundry | April 7, 2026

What if the reason you feel tired, foggy, or just “off”… has nothing to do with your age, stress, or even your diet?

What if it’s your environment?

The reality is, most of us now spend nearly 93% of our lives indoors—and according to today’s guest, that shift may be quietly disrupting everything from your sleep and metabolism… to your brain function and immune system.

In this episode, I’m joined by Dr. John La Puma, author of Indoor Epidemic, to uncover how modern indoor living is impacting your health in ways most people never consider.

You’ll learn all about major hidden threats, how poor indoor air can affect your focus and decision-making, and why the air inside your home may be more harmful than what’s outside.

Most importantly, we share simple, science-backed solutions you can start today ” to help reset your body.

Because sometimes, it’s not just what you eat…it’s where you live.
