Daylight: Your Secret Weapon for Immunity - AI Podcast

Story at-a-glance

• Your immune system’s frontline defenders, called neutrophils, are most powerful in the early morning when activated by daylight exposure
• Light works like an internal alarm, switching your immune response on at the right time and boosting your body’s ability to fight infection
• When you stay up late, miss morning sunlight or get too much artificial light at night, your immune rhythm falls out of sync, leaving you more vulnerable
• Research shows that your immune system is not only reactive but timed, meaning when you’re exposed to pathogens matters as much as how your body fights them
• Simple changes, like getting outside in the morning and limiting screen use before bed, reprogram your immune system to respond faster and more effectively
