Intense light may boost heart health
Recent research shows that intense light therapy may be beneficial for the heart. Researchers discovered that intense light influences the functions of the PER2 gene. This gene is expressed by a part of the brain that controls circadian rhythms.
When boosting this gene through intense light therapy, it was discovered that mice’s heart tissue received extra protection when experiencing issues with oxygen, for example, like during a heart attack. The light also increased cardiac adenosine, a chemical that helps with blood flow regulation.
When tested in humans, PER2 levels increased in response to light therapy as it did in the mice. Human volunteers saw a decreased level of plasma triglycerides and improved metabolism.
Further research is needed in humans to understand the impact of intense light therapy and its potential for cardiovascular protection. The findings from this study have been published in the journal Cell Reports.
New research in mice and humans finds that exposure to intense light therapy can boost the heart’s protection against a heart attack.
