IgG tests are often marketed to detect food sensitivities, but evidence for a causal link with sleep quality or disorders is largely absent. Most studies on IgG and symptoms like fatigue or sleep issues are small, uncontrolled, or rely on self-reports. Moreover, IgG antibodies to foods are common in healthy individuals and are generally considered a normal physiological response to food intake, not a pathology. Sleep is regulated by a complex interplay of circadian rhythms, neurotransmitters, hormones (melatonin, cortisol), and lifestyle factors. A direct IgG-mediated disruption of this system is not established. If you have sleep problems, first pursue evidence-based approaches such as sleep hygiene, stress management, and medical evaluation before investing in costly IgG tests.
