Sleep Deprivation Can Affect Your Gene Expression

Posted Mar 01 2013 10:33pm

Conventional thinking states that your genes don’t change, but here’s a revealing study that shows how sleep can significantly affect levels of gene expression. In this study, even mild levels of sleep deprivation or circadian rhythm disruption were found to increase or decrease expression of up to 711 genes, based on a technique called transcriptome analysis.

Biological areas affected included the following: gene-expression regulation, chromatin modification, macromolecular metabolism, and inflammatory, immune and stress responses.

What this means is that poor sleep, whether it’s due to insufficient sleep, insomnia, or sleep apnea, can have a negative effect on your hormones, metabolism, immune system, and your stress response.
