What Are The Causes And Effects Of Chronic Loneliness?

Loneliness is an emotional state in which a person experiences a powerful feeling of emptiness and isolation. Loneliness has increased with modernization and is an invisible epidemic that affects people worldwide.

Loneliness, according to many experts, is not necessarily about being alone. Instead, it is the perception of being alone and isolated.

Studies have shown that loneliness and lack of companionship have detrimental effects on the physical and mental health of an individual. Everyone feels lonely at times in their lives, but chronic loneliness poses a serious health risk.

What Causes Loneliness?

Loneliness can be attributed to internal factors such as low self-esteem. Contrary to what many people believe, loneliness isn’t just a result of being alone or an absence of friends. It is a deeper problem that is caused by thoughts and feelings of inadequacy, imperfection and shame.


Chronically lonely people are often holding onto pessimistic thoughts and have negative predictions about the prospects of finding companionship, social connections and supportive relationships. This can lead to isolation and chronic loneliness.

According to research by John Cacioppo, loneliness is strongly connected to genetics. Other contributing factors include situational variables, such as physical isolation, moving to a new location and divorce. The death of someone significant in a person’s life can also lead to feelings of loneliness.


Loneliness can also be a symptom of a psychological disorder such as depression.1

Negative Impact Of Loneliness On Physical and Mental Health

Loneliness has a wide range of negative effects on both physical and mental health. Some of the the health risks associated with loneliness include:


1. Loneliness Can Affect The Brain Like Physical Pain

Emerging evidence suggests that experiences of social pain and the painful feelings associated with social disconnection, rely on some of the same neurobiological substrates that underlie experiences of physical pain.2 The brains of lonely individuals register feelings of threat and pain signals that are similar to real physical pain and danger.3

2. Reduces Life Expectancy

Loneliness can be fatal enough to cause premature death. Studies show that people who live unaccompanied are more likely to have an early death caused by stroke, heart attacks or other complications than those who live with their family or in a communal institution.


In the case of older individuals, those who reported feeling isolated, rejected or lonely had an increased chance of dying even though they were not living alone practically.4

3. Increases The Risk Of Dementia

The feeling of loneliness raises the risk of Dementia or Alzheimer’s disease by 64%. Feeling lonely rather than being alone, is associated with an increased risk of clinical dementia in later life and can be considered a major risk factor that, independently of vascular disease, depression and other confounding factors, deserves clinical attention.


According to studies, those living alone or staying in nursing homes and old age institutions have greater chances of developing dementia than those staying with their families.5

4. Increases The Risk of Heart Disease

According to various studies, loneliness was found to be associated with an increased probability of having a heart condition. In addition, unfavorable perceptions of one’s health status was associated with feeling lonelier and an increased probability of having a heart condition.


The genes of chronically lonely individuals experience over-expression, leading to long-term inflammation and damage to the tissues and blood vessels of the heart increasing the risk of heart attack, stroke and other cardiovascular diseases.6

5. Causes Sleeping Disorders

Psycho-social factors such as retirement, isolation and loneliness may promote insomnia in older people. There is a close relation between loneliness and sleep and even minute difference in the level of loneliness has an effect on sleep.

It has been seen that lonely individuals experience more trouble with sleep. Loneliness hinders restful sleep and lonely people experience disturbed sleep.7
