The science of sleep and practical habits for sleeping better

Learn how orexin neurons keep you alert during the day and why their failure causes daytime drowsiness—critical for recognizing when you're fighting your own biology at work.

Understand how orexin and adenosine work against each other throughout your day, so you can time your energy peaks and manage afternoon slumps professionally.

Apply evidence-based habits—light exposure, movement, and timing—that naturally strengthen orexin signaling to stay sharp during meetings and critical tasks.

Connect poor sleep to reduced orexin function and see how even one night of recovery sleep restores your alertness, decision-making, and workplace credibility.
