What if some of your unexplained symptoms aren't coming from your body—but from your home? The air you breathe, the water you drink, and the products and materials surrounding you every day may be exposing you to hidden environmental toxins that quietly affect your health, energy, and even your longevity.

Today on The Dhru Purohit Show, Dhru sits down with Dom Francks, General Manager and a founding team member of Lightwork Home Health, to uncover the hidden environmental factors that could be affecting your health without you even realizing it. Dom shares the research-backed assessment process his team uses to identify the most common environmental toxins found in homes, the biggest problem areas they see, and the practical steps you can take to reduce your exposure. Dhru also shares the personal health journey that led him to have his own home assessed and what he and Dom discovered along the way.
