Common mistakes around Schlaf Genetik

Common mistakes around sleep genetics: Many people assume a single gene (e.g., CLOCK, PER3, or the CAT gene mentioned here) directly determines sleep quality or duration. In reality, sleep is highly polygenic, with hundreds of variants each contributing tiny effects. Another mistake is confusing association with causation – GWAS findings show correlations, not proof that a variant causes poor sleep. Environmental factors like light exposure, stress, diet, and sleep hygiene are often underestimated. Direct-to-consumer genetic tests frequently overstate predictive power; their polygenic risk scores lack clinical validation and are ancestry-dependent. For example, the CAT gene (catalase) helps manage oxidative stress, which can affect sleep, but a single polymorphism does not cause insomnia or sleep apnea. People also forget that genetic effects can be modified by lifestyle – e.g., exercise and nutrition can blunt negative variants. The biggest mistake is treating a DNA test result as destiny. Sleep is complex; genetics is just one piece. Always consult a healthcare professional before making drastic changes based on genetic data.
