Text me what you thought of the show 😊 Shift work disrupts circadian rhythm and quietly increases the risk of heart disease, hormonal imbalance, fatigue, and metabolic disorders. In this episode, we explain The 176 Rule for shift workers - a simple health framework designed to detect hidden stress before symptoms appear. You’ll learn how tracking resting heart rate, blood pressure, and regular blood tests can reveal early warning signs caused by night shift work, rotating shifts, and irr...

Text me what you thought of the show 😊 We make a direct call to leaders of 24/7 teams to stop relying on recruitment and start building real support that reduces fatigue and burnout. Practical education, risk-aware supervision, and retention-first strategy create safer, more stable workplaces. • Why recruitment cannot fix fatigue and burnout • The compounding loop from errors to understaffing • Evidence-based education on sleep, circadian rhythm, nutrition, recovery • What genuine support...

Text me what you thought of the show 😊 We break down how shift work disrupts circadian rhythms and why that drives metabolic, cardiovascular, gut, immune and mental health risks. Then we lay out practical, evidence-based steps for sleep timing, light control, meal timing, movement and routines that protect your body. • Circadian disruption as the root driver of health risks • Metabolic strain, insulin resistance and type 2 diabetes • Cardiovascular load, elevated blood pressure and resting h...

Text me what you thought of the show 😊 We unpack how light shapes sleep, mood, and performance, then connect it to the real strain on shift workers and police. Practical tools for anxiety, pain, and late-night routines give listeners immediate steps while we challenge how systems value frontline health. • why daylight calibrates circadian rhythm and melatonin • hidden harms of indoor LEDs, screens, and blue-heavy light • day lenses versus full blue blockers and when to use each • simple morn...

Text me what you thought of the show 😊 In this episode, we break down what’s really happening when women work nights and why the research shows a higher risk of breast cancer in long-term night shift workers. More importantly, you’ll learn what you can do right now to reduce that risk in a practical, realistic way. Here’s what we cover: • How night shift disrupts your circadian rhythm and hormone balance • What large long-term studies are showing about elevated breast cancer risk ...
