Are stress and sleepless nights silently damaging your immune system? This powerful new study reveals how anxiety and insomnia can drastically lower your body’s natural killer (NK) cell count — the very immune cells responsible for fighting off infections, viruses, and even cancer. Researchers found that the more anxious or sleep-deprived you are, the fewer NK cells your body has to protect you.
In this video, we break down the science in just 60 seconds — what NK cells do, how stress impacts them, and why your mental health directly affects your immune system. If you’ve been feeling run-down, anxious, or losing sleep, this is a must-watch.
