  • Genome-wide meta-analysis of insomnia prioritizes genes associated with metabolic and psychiatric pathways. - Nature genetics (2022) · Watanabe K, Jansen PR, Savage JE, Nandakumar P, Wang X, Hinds DA, Gelernter J, Levey DF, Polimanti R, Stein MB, Van Someren EJW, Smit AB, Posthuma D · PubMed 35835914

    Insomnia is a heritable, highly prevalent sleep disorder for which no sufficient treatment currently exists. Previous genome-wide association studies with up to 1.3 million subjects identified over 200 associated loci. This extreme polygenicity suggested that many more loci remain to be discovered. The current study almost doubled the sample size to 593,724 cases and 1,771,286 controls, thereby increasing statistical power, and identified 554 risk loci (including 364 novel loci). To capitalize on this large number of loci, we propose a novel strategy to prioritize genes using external biological resources and functional interactions between genes across risk loci. Of all 3,898 genes naively implicated from the risk loci, we prioritize 289 and find brain-tissue expression spec

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Diet

  • Caffeine in afternoon and evening Moderate

    Caffeine blocks adenosine sleep signaling and delays sleep onset, particularly problematic with genetic insomnia susceptibility.

    Eliminate caffeine intake after 12 PM, all sources (coffee, tea, energy drinks, sodas, chocolate)

Exercise

  • Aerobic exercise for insomnia prevention Moderate

    Regular aerobic activity improves sleep architecture through circadian synchronization and sleep homeostasis regulation.

    150 minutes moderate-intensity or 75 minutes vigorous-intensity aerobic exercise weekly

Lifestyle

  • Consistent sleep-wake schedule Moderate

    Regular sleep timing stabilizes circadian rhythm and improves sleep consolidation in individuals with insomnia genetic predisposition.

    Maintain same bedtime and wake time daily, within 30 minute variation including weekends

  • Optimize bedroom sleep environment Moderate

    Cool, dark, quiet environment reduces sleep latency and arousals; especially important for genetically vulnerable individuals.

    Keep bedroom 65-68F, dark (blackout curtains), quiet (earplugs or white noise), remove distracting light sources

Screening

  • Sleep quality tracking Moderate

    Early identification of sleep deterioration in genetically predisposed individuals enables timely intervention before chronic insomnia develops.

    Weekly assessment of sleep duration and daytime impairment; formal sleep study if problems persist beyond 2-4 weeks
