“What I see is exhaustion in the body while the nervous system is still on alert. Stress, late blue light, or a 2 to 4 a.m. blood sugar dip spike cortisol, suppress melatonin, and leave you tired but wired.”

“I see this most with parents who are running on fumes: the body floods with cortisol and adrenaline to keep you upright, and those same stress hormones make it impossible to drop off when you finally get the chance. The exhaustion is real, but sleep is a skill, and an overtired brain and body need structure, not just a pillow.”

“Exhaustion without sleep usually means your arousal system is still running: cortisol, a racing mind, or a body that learned to associate the bed with struggle. In my practice I treat insomnia by combining behavioral resets with biological support, because willpower alone rarely overrides a wired nervous system.”
