Salim Najjar’s journey through the realms of health and wellness is both a deep dive into ancient wisdom and a foray into modern biohacking. His work, especially in the field of Heart Rate Variability (HRV), serves as a crucial link between physical health and emotional well-being, offering insights into how our bodies respond to stress at a cellular level.

Najjar emphasizes the significance of HRV as the primary biomarker for assessing overall health, longevity and wellness. He suggests that prolonged stress, which manifests through the autonomic nervous system, is the root cause of all aging, disease and eventually death. By understanding and optimizing HRV, which is a direct reflection of your relationship to stress, individuals can regulate their nervous system leading to better health outcomes.

“If you stay in the sympathetic adrenaline, cortisol, high beta state for consistent long periods of time, that's what creates inflammation on a cellular level which leads to aging and disease in the body” Najjar said in the Biohack Yourself Documentary.

Incorporating a variety of ancient modalities and biohacking techniques, Najjar explores the benefits of several modalities including ketosis, red light therapy, and PEMF (Pulsed Electromagnetic Fields) to enhance physical performance and mental clarity. He also delves into the importance of sleep, meditation, and breathwork as foundational practices to counteract the daily stressors of modern life.

“Sleep is the only thing evolution hasn’t gotten rid of,” Najjar said. “And that is when we’re in our deepest parasympathetic state. So absolutely crucial you get good sleep.”

Salim's holistic approach is grounded in the belief that every aspect of life—from diet and water intake to the use of nutraceuticals and sound therapy—affects our overall well-being. His insights provide a roadmap for those looking to harmonize their body, mind and spirit through a blend of traditional practices and cutting-edge biohacking strategies.

“HRV is not just about what you do physically, as it’s a measure of how your heart perceives its ever changing environment. This includes what you watch, what you listen to and who you’re with. Every single thing that you do impacts your HRV, impacts how your heart feels in this present moment.”
