The Claim

Sleep disorders, including insomnia, sleep apnea, and narcolepsy, are associated with a 44% increased risk of ischemic heart disease, and this association suggests that disrupted sleep physiology may directly contribute to cardiovascular pathology through mechanisms involving inflammation, sympathetic overactivation, and metabolic dysfunction.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

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

How it works
1 study reviewed
In plain English

People who have trouble sleeping—like not being able to fall asleep, stopping breathing at night, or falling asleep at the wrong times—are much more likely to develop heart disease, and it might be because poor sleep messes up the body’s stress, inflammation, and metabolism systems.

What the research says

1 study
  1. Study: Causal association between sleep duration, daytime napping, sleep disorders and ischemic heart disease: A systematic review and meta‑analysis of Mendelian randomization studies

    This study found that people with sleep problems like insomnia or sleep apnea are 44% more likely to have heart disease, which is exactly what the claim says — so it supports it.
