Following a heart attack, immune cells stimulate sleep neurons promoting deep slumber, aiding recovery by reducing inflammation in the heart. Research involving mice and humans shows that adequate sleep facilitates healing after a heart attack. Sleep and cardiovascular health are interconnected, with poor sleep increasing the risk of high blood pressure. Experiments on mice revealed that immune cells in the brain produce a protein that induces sleep, highlighting the importance of rest in recovery. Human studies also showed that lack of sleep post-heart attack is linked to more serious cardiovascular issues. Clinicians stress the importance of quality sleep for long-term heart health.
