Why sleeping less than 7 hours can lead to heart disease and Type 2 diabetes

Do you get enough sleep? If not, that could be a potentially fatal problem.

Decades of research has shown that chronic short sleep is associated with increased risk of clogged arteries, heart disease, and early mortality. A new study in the monthly peer-reviewed journal Experimental Physiology has a theory on why lack of sleep increases susceptibility to heart disease.

Adults who regularly slept fewer than 7 hours per night have lower levels of certain “microRNAs,” molecules that influence the function of genes. These molecules play a key role in regulating vascular health and can be biological indicators of cardiovascular health.
