Aarav woke up at 6:00 AM. He didn't stretch. He didn't look out the window. The first thing he did was tap his wrist. The screen of his smartwatch glowed in the semi-darkness. Sleep Score: 64. Recovery: 32%. HRV: Low. "Damn it," Aarav hissed. He felt fine. Actually, he felt rested. But the data said he should feel terrible. And because the data said it, his body obediently fell into line. Within seconds, a phantom fatigue washed over him. This was the Nocebo Effect of the digital age.
