Sleep quality is directly affected by several measurable biomarkers. Thyroid dysfunction (TSH) can cause insomnia or excessive sleepiness. Cortisol dysregulation — tested with both AM and PM draws — reveals whether your natural cortisol rhythm is disrupted, a common cause of difficulty falling asleep or waking at 3 AM. Iron deficiency (Iron Panel + Ferritin) is the leading cause of restless leg syndrome. Low magnesium impairs GABA activity and muscle relaxation. Vitamin D deficiency is associated with shorter sleep duration and poorer sleep quality. Blood sugar instability (A1c) can cause nighttime awakenings from nocturnal hypoglycemia. This panel identifies the treatable conditions most often responsible for sleep problems.
