The Claim

Chronic intermittent hypoxia in male mice induces tissue-specific DNA methylation changes in the left cardiac ventricle and peripheral blood mononuclear cells, resulting in 5,747 differentially methylated positions in cardiac tissue and 1,307 in blood, leading to accelerated epigenetic aging at 7 days and persistent vascular dysfunction characterized by elevated systolic and diastolic blood pressure and reduced coronary flow reserve.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In male mice, repeated episodes of low oxygen exposure cause measurable changes in DNA methylation patterns in the heart and blood cells, resulting in faster epigenetic aging after 7 days and sustained increases in blood pressure with reduced blood flow to the heart.

See the scientific wording

Chronic intermittent hypoxia in male mice induces tissue-specific DNA methylation changes in the left cardiac ventricle and peripheral blood mononuclear cells, with 5,747 differentially methylated positions in cardiac tissue and 1,307 in blood, leading to accelerated epigenetic aging at 7 days and persistent vascular dysfunction including elevated systolic and diastolic blood pressure and reduced coronary flow reserve.

Why this might work

Low oxygen episodes cause chemical changes to DNA in heart and blood cells, turning on a gene that makes a protein called p16. This protein stops blood vessel cells from dividing and forces them into an aging state. These aged cells stiffen blood vessels, reduce blood flow to the heart, and raise blood pressure. Removing these aged cells reverses all these problems.

  1. Study: Intermittent Hypoxia Mimicking Sleep Apnea Induces Systemic and Tissue Specific Epigenetic Changes and p16-Mediated Cellular Senescence Underlying Vascular Dysfunction

    In male mice, repeated low-oxygen episodes (like sleep apnea) change how genes are regulated in the heart and blood cells, leading to higher blood pressure and less blood flow to the heart. Removing certain aging cells reversed these problems, proving the link.
