Biological effects of insomnia on the heart
“When you suffer from chronic insomnia, your body is in a state of prolonged stress, triggering the release of cortisol and other stress hormones,” says Dr. Aravind Badiger, Technical Director, BDR Pharmaceuticals (India).
Over time, elevated cortisol levels lead to high blood pressure, increased heart rate, and an increased risk of atherosclerosis, a condition in which plaque builds up in the arteries, narrowing them and increasing the risk of heart attack or stroke. Atherosclerosis is often the first step toward cardiovascular events, and insomnia plays a role in its development.
Psychological impact and cardiovascular health
In addition to physical health, insomnia is also closely linked to mental health problems, especially anxiety and depression. Chronic insomnia increases the risk of these conditions, which also affect cardiovascular health.
Mental health problems can lead to increased inflammation in the body, which is another risk factor for heart disease, Dr. Badiger added. In addition, people who regularly have trouble sleeping may adopt unhealthy lifestyles, not exercise, and turn to alcohol and smoking as coping mechanisms. These lifestyle factors further increase the risk of cardiovascular disease.
Effective treatment for insomnia and reduced cardiovascular risk
- Make sure you have a regular sleep schedule, even on weekends and holidays.
- Go to bed early enough to ensure you get 7-8 hours of sleep.
- Establish a relaxing bedtime routine with low light and no electronic devices.
- Do not eat too much before going to bed, avoid drinking caffeinated drinks in the afternoon and evening.
- Exercise regularly, maintain a healthy diet, and avoid drinking alcohol before going to bed.
