Sleep is a fundamental pillar of good health, especially when it comes to maintaining a healthy heart. Poor sleep quality has been closely linked to an increased risk of cardiovascular diseases, including high blood pressure and irregular heart rhythms. Dr Ian Weisberg, a leading cardiology expert, underscores the importance of restful sleep and how making lifestyle adjustments can significantly improve heart health.
How Sleep
Impacts Heart Function
Research indicates that insufficient sleep can contribute to elevated blood
pressure, systemic inflammation, and insulin resistance—all major contributors
to heart disease. According to Dr Ian
Weisberg, lack of sleep disrupts the body’s ability to manage stress
hormones such as cortisol, placing additional strain on the cardiovascular
system. Sleep deprivation also interferes with the autonomic nervous system,
which controls heart rate and blood pressure regulation, making individuals
more vulnerable to heart conditions.
