American researchers find that sleeping lights affect heart rehabilitation

Recently, in a study funded by the National Institutes of Health, neuroscientists at the University of Texas at Austin and West Virginia University School of Medicine discovered that white light at night (usually used to illuminate the ward) and inflammation, brain There is a link between cell death and high mortality in heart disease patients.

The team reconstructed cardiac arrest with animal models, allowing the three groups to spend the night in dim red, dim white and dark. After 7 nights, the researchers assessed their health.

The results showed that nighttime exposure to white light resulted in a variety of adverse outcomes: a group of subjects exposed to white light at night had an increased mortality rate, and there was no difference in mortality between exposure to the red light group and the group in the dark. Researchers believe that nighttime exposure to white light can affect the hippocampus (the part of the brain that plays a key role in memory formation) and cause a more intense inflammatory response.

This shows that changing the color of the night light, from broad-spectrum white to red or turning off the light, is conducive to the prognosis of heart disease. The results of this research have been published in Experimental Neurology. Since the current research results are derived from animals, future studies can prove that this conclusion is equally applicable to the clinical population and will contribute to the rehabilitation of hospitalized cardiac arrest patients.
