Myths vs facts: Body-Balance Check | Testosteron-Test and sleep

The Body-Balance Check by MyBody-X is a hormone test that measures testosterone among other markers. There is scientific evidence that low testosterone levels are associated with sleep disturbances such as reduced sleep quality or shorter sleep duration. However, the evidence is complex: studies show testosterone influences circadian rhythms, but causality is often bidirectional – sleep deprivation lowers testosterone, and low testosterone can impair sleep. The test only measures hormone levels at a single time point, not sleep quality. MyBody-X markets the test for energy and well-being, not specifically for sleep. Therefore, claims that the test can explain sleep issues are largely marketing-driven. For proper sleep diagnostics, sleep labs or validated questionnaires are more appropriate. The test can provide supplementary information but should not be the sole basis for sleep optimization. Evidence: marketing, as no direct studies on this specific test and sleep exist.
