Chronic fatigue isn’t just a state of mind; it’s a physiological condition often rooted in poor sleep, and it acts as an unseen saboteur of your heart health. While you might blame your exhaustion on a busy schedule, the underlying lack of restorative rest is actively working against your cardiovascular system.
This sabotage begins with the body’s stress response. When you are chronically fatigued from poor sleep, your body perceives a constant state of emergency. It keeps stress hormones like cortisol elevated, which in turn keeps your blood pressure and blood sugar levels high. This sustained internal stress is a direct pathway to heart disease.
The saboteur also attacks your motivation and judgment. When you’re exhausted, you’re far less likely to have the energy to exercise or the willpower to make healthy food choices. You’re more likely to reach for sugary, high-caffeine drinks and convenience foods, which further strain your heart.
Most importantly, the heart muscle itself is a victim of this fatigue. It is denied the essential period of deep sleep required for cellular repair and recovery. A heart that never gets to fully rest is a heart under strain, making it more vulnerable to damage. Addressing the root cause of your fatigue—often, a lack of quality sleep—is critical to stopping this sabotage and protecting your heart.
