Why people sometimes feel lonely?
Loneliness is a feeling that can occur when a person lacks companionship or feels disconnected from their social network. It is a common experience and is not necessarily tied to being alone. Some people may feel lonely even when they are surrounded by others, while others may not feel lonely even when they are alone. There are many reasons why people may feel lonely, including lack of social support, loss of a loved one, and physical isolation. In some cases, loneliness may be a symptom of underlying mental health issues, such as depression or anxiety. If you are feeling lonely, it is important to reach out to friends, family, or a mental health professional for support.
What happens in a human brain, when person feels lonely?
There is some evidence to suggest that loneliness activates the brain’s stress response, which can have negative impacts on both physical and mental health. When a person feels lonely, they may perceive a threat to their social connections, and this activates the release of stress hormones such as cortisol. Chronic activation of the stress response can lead to a variety of negative health outcomes, including increased blood pressure, impaired immune function, and even an increased risk of premature death.
At the same time, loneliness can also impact the brain in more subtle ways. For example, loneliness has been linked to changes in brain function and structure, particularly in areas involved in social connection and cognition. Some studies have also found that loneliness is associated with changes in the way the brain processes social stimuli, such as facial expressions and voices, which may make it more difficult for a person to connect with others.
It is important to note that these findings are still preliminary, and more research is needed to fully understand the effects of loneliness on the brain. However, it is clear that loneliness is a significant public health concern and can have serious consequences for both physical and mental health.
