  • Genome-wide analysis of insomnia in 1,331,010 individuals identifies new risk loci and functional pathways. - Nature genetics (2019) · Jansen PR, Watanabe K, Stringer S, Skene N, Bryois J, Hammerschlag AR, de Leeuw CA, Benjamins JS, Muñoz-Manchado AB, Nagel M, Savage JE, Tiemeier H, White T, Tung JY, Hinds DA, Vacic V, Wang X, Sullivan PF, van der Sluis S, Polderman TJC, Smit AB, Hjerling-Leffler J, Van Someren EJW, Posthuma D · PubMed 30804565

    Insomnia is the second most prevalent mental disorder, with no sufficient treatment available. Despite substantial heritability, insight into the associated genes and neurobiological pathways remains limited. Here, we use a large genetic association sample (n = 1,331,010) to detect novel loci and gain insight into the pathways, tissue and cell types involved in insomnia complaints. We identify 202 loci implicating 956 genes through positional, expression quantitative trait loci, and chromatin mapping. The meta-analysis explained 2.6% of the variance. We show gene set enrichments for the axonal part of neurons, cortical and subcortical tissues, and specific cell types, including striatal, hypothalamic, and claustrum neurons. We found considerable genetic correlations with psychiatric tr

Lifestyle context

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

Diet

  • evening caffeine Moderate

    Caffeine can exacerbate sleep susceptibility; individuals with genetic predisposition may be particularly sensitive

    Avoid caffeine after 2 PM, maximum 200mg before noon

Discuss with your doctor

  • insomnia screening and CBT-I consideration Moderate

    Genetic predisposition to insomnia warrants proactive sleep medicine evaluation

    Discuss with primary care or sleep medicine specialist, consider CBT-I if insomnia symptoms develop

Exercise

  • regular aerobic exercise (morning/afternoon timing) Moderate

    Exercise improves sleep quality; morning/afternoon timing avoids sleep disruption, particularly important for genetically predisposed individuals

    30 minutes moderate aerobic activity, scheduled before 4 PM, at least 5 days per week

Lifestyle

  • sleep hygiene optimization Moderate

    Consistent sleep-wake timing and sleep environment optimization may reduce genetic predisposition to insomnia

    Maintain consistent bedtime/wake time, keep bedroom cool dark quiet, limit evening screen time after 9 PM

Screening

  • sleep quality assessment Moderate

    Genetic variant associated with 4.2% increased insomnia risk in large GWAS

    Annual sleep quality assessment, consider polysomnography if symptoms develop
