Three Sleepless Nights May Harm Your Heart: New Research Reveals Immediate Cardiovascular Risks
A groundbreaking new study from Sweden has found that even brief periods of poor sleep—just three nights of getting only four hours per night—can cause measurable changes in the blood that are linked to an increased risk of heart disease. This research, published in the journal Biomarker Research and summarized by Neuroscience News, underscores the critical health threat posed by short-term sleep deprivation, especially among young, healthy adults who may feel immune to cardiovascular danger.
