How Sleep Loss Affects Your Heart

Getting too little sleep has been shown to have bad effects on the heart, and many studies have linked it to hypertension. Now, a small new study published in the journal Hypertension finds that shortened sleep is connected to some negative markers, especially when it occurs outside of typical nighttime hours.

In the study, which was conducted at a University of Chicago sleep lab, 26 healthy young adults were assigned to a week of shortened sleep, with just five hours of shut-eye each night.
