Chinyelu Oraedu, an academic hospitalist and nocturnist, breaks down what really happens to a doctor's body at 2 a.m., why most night shift workers never recover their sleep, and the one habit that changed her career on nights.

About this episode:
Chinyelu Oraedu is an academic hospitalist and nocturnist who has worked nights for 17 years and built a platform, Dr. Yara, focused on helping clinicians survive shift work. She argues that 2 to 3 a.m. is the biological crossroads of the night shift, when melatonin peaks, alertness drops, and most cardiac arrests happen, exactly when a tired physician has to run a code. She walks through what works and what does not, from the strategic use of caffeine and bright light at the start of a shift to chronotype alignment and the small, unglamorous habits that protect sleep, like dark curtains, meal prep, and a note on the door for the landscaper. She names sleep as the single non-negotiable, the one variable that, when she stopped compromising it five years in, turned her night shift career around. She tells the story of her own gestational diabetes, missed for two months during a busy residency, as a warning about what happens when high performers stop watching their own health. She closes with a reframing of night shift as a season, not a sentence, and asks the field to see the people who keep hospitals running while everyone else sleeps.

Tune into our episode "2026 Cholesterol Guidelines: LDL goals, lipoprotein(a), and coronary calcium scoring," brought to you by Novartis Pharmaceuticals Corporation.

For the first time in eight years, LDL cholesterol goals have changed, and preventive cardiologist Seth Baum says the new guidelines are a long-overdue course correction. He breaks down the new LDL targets for your highest-risk patients, why the LDL hypothesis should be retired in favor of the LDL fact, why lipoprotein(a) screening finally belongs in every patient's workup, what a coronary calcium score over 300 really means for how aggressively you treat, and how to talk to statin-skeptical patients without losing their trust.
