Myths vs facts: Hormoncheck Männer and Schlaf

Myth: A hormone check alone tells you if a man sleeps well. Fact: Sleep deprivation demonstrably lowers testosterone levels, but a hormone check only captures a snapshot. Chronic sleep loss can raise cortisol and disrupt testosterone production. However, the relationships are complex: stress, diet, exercise, and age also play major roles. A hormone check is useful when specific symptoms like fatigue, low libido, or erectile dysfunction are present, but it does not replace sleep hygiene or medical evaluation. Evidence comes from observational studies; randomized controlled trials show moderate effects. Beware of overinterpreted results from direct-to-consumer tests – reference ranges are often not standardized.
