Loneliness is a feeling of isolation and disconnection from the people around us. It is a common experience for all of us at some point in our lives.

According to a study by the American Psychological Association, loneliness is becoming increasingly prevalent in modern society with more than 42.6 million adults in the U.S. considered to be lonely.

The effects of loneliness are not limited to our emotional wellbeing. They extend to our physical health, with research indicating that loneliness increases the risk of developing heart disease.

What is it?: Heart disease

Heart disease includes conditions that affect the heart and blood vessels, such as heart attack, coronary artery disease, heart failure, and arrhythmia. It is the leading cause of death in the United States, accounting for one in four deaths each year.

Heart disease can develop over time, and various factors contribute to its development. These risk factors include high blood pressure, high cholesterol, smoking, obesity, physical inactivity, and diabetes.

Understanding the link between loneliness and heart disease

The link between loneliness and heart disease has been studied extensively. Various factors explain the relationship between loneliness and cardiovascular health, including:.

1. Stress

Loneliness is a source of stress, and stress is known to have adverse effects on heart health. Chronic stress increases blood pressure, damages blood vessels, and promotes inflammation that is associated with heart disease.

Being socially isolated means that there is less emotional and practical support.

Lack of social support can lead to uncontrolled high blood pressure, unhealthy dietary patterns, and decreased physical activity—all of which are risk factors for heart disease.

3. Behavioral factors

Loneliness can lead to unhealthy behaviors such as smoking, excessive drinking, unhealthy eating habits, and a sedentary lifestyle, all of which contribute to the development of heart disease.

4. Biological factors

Loneliness can also have biological effects on health. It can cause a chronic state of inflammation, which is an underlying mechanism of heart disease.

There is no doubt that loneliness has negative effects on cardiovascular health. However, the good news is that it is a modifiable risk factor. In other words, social connections can have cardiovascular benefits and prevent heart disease.

Below are ways to increase social interactions and create supportive networks:.

1. Join clubs and groups

Joining clubs, societies, or groups that interest you is an excellent way to meet people who share your passion. These groups could be book clubs, hiking clubs, exercise groups, etc.

2. Attend community events

School gatherings, religious events, and neighborhood meetings are places where you can interact with people who live within your locality or share similar beliefs and interests.

3. Volunteer

Volunteering for a cause that is meaningful to you is fulfilling and an effective way to meet people. Organizations such as Habitat for Humanity, The Red Cross, and animal shelters are examples of where you can volunteer.

Conclusion

Loneliness can affect our physical health and increases the risk of developing heart disease. Activities that strengthen social connections and provide emotional support are essential in promoting cardiovascular health and preventing heart disease.
