Ever wondered why heart rhythm problems often occur in the morning? Researchers from Imperial College London discovered that it’s linked to the natural surge of the stress hormone cortisol, which peaks in our blood when we wake up. This hormone influences genes regulating ion channels in heart cells, making the heart more vulnerable to disturbances. The study in mice found that inhibiting the cortisol receptor prevented these morning changes, hinting at potential treatments. The findings shed light on the ancient circadian rhythms affecting our hearts and could pave the way for new prevention strategies. Check out the details of this intriguing study led by Dr. Alicia D’Souza from Imperial’s National Heart and Lung Institute!

it’s fascinating to learn about the link between cortisol and heart arrhythmia, especially how it’s tied to our natural circadian rhythms! I had no idea that our hearts are more vulnerable in the morning due to these ancient rhythms.
