What role does Fitness | LifestyleCheck play in Schlaf?

The role of fitness and lifestyle checks in sleep is supported by observational evidence, but the predictive power of genetic tests for sleep remains limited. Regular exercise, balanced nutrition, and good sleep hygiene are known to improve sleep quality. However, most commercial sleep-related genetic tests lack robust clinical validation. Evidence is primarily from observational studies and mechanistic data, not from large randomized trials. A lifestyle check can serve as a general health guide but should not be mistaken for a medical diagnostic tool. Effects are highly individual and influenced by environmental factors. Beware of exaggerated marketing claims: a genetic test alone cannot diagnose sleep disorders or guarantee personalized sleep optimization.
