Feeling lonely can also have a negative impact on your mental health, especially if these feelings have lasted a long time. Some research suggests that loneliness is associated with an increased risk of certain mental health problems, including depression, anxiety, low self-esteem, sleep problems and increased stress.
Research has linked social isolation and loneliness to higher risks for a variety of physical and mental conditions: high blood pressure, heart disease, obesity, a weakened immune system, anxiety, depression, cognitive decline, Alzheimer's disease, and even death.
Hawkley points to evidence linking perceived social isolation with adverse health consequences including depression, poor sleep quality, impaired executive function, accelerated cognitive decline, poor cardiovascular function and impaired immunity at every stage of life.
It's characterized by constant and unrelenting feelings of being alone, separated or divided from others, and an inability to connect on a deeper level. It can also be accompanied by deeply rooted feelings of self-doubt, low self-esteem, or social anxiety.
It is not surprising that loneliness hurts. A brain imaging study showed that feeling ostracized actually activates our neural pain matrix. In fact, several studies show that ostracizing others hurts us as much as being ostracized ourselves.
These feelings of loneliness may ultimately lead to posttraumatic stress symptoms via a number of pathways. For example, loneliness may lead to the development of negative cognitions (Cacioppo and Hawkley, 2009), which can predict future PTSD symptoms and impact PTSD treatment (Brown et al., 2019).
When someone feels lonely they are more likely to try to distract themselves with the other things in their lives. So if your colleague is always talking about their stamp collection, or always flying away on exotic solo city breaks rather than spending weekends at home, they might be feeling alone.
"Loneliness can change the neurochemistry of the brain, turning off the dopamine neurons, which trigger the reward response, and causing some degeneration in the brain when the reward response is not activated," says Katherine Peters, MD, PhD, FAAN, associate professor of neurology and neurosurgery at Duke University.
Loneliness is associated with higher blood pressure and heart disease — it literally breaks our hearts. A 2015 meta-review of 70 studies showed that loneliness increases the risk of your chance of dying by 26 percent.
Definition of Loneliness
Loneliness causes people to feel empty, alone, and unwanted. People who are lonely often crave human contact, but their state of mind makes it more difficult to form connections with other people. Loneliness, according to many experts, is not necessarily about being alone.
Loneliness is toxic
Loneliness has clear consequences for mental health, aggravating anxiety, depression, and stress-related symptoms. Additionally, it sabotages our physical health.
Three profiles of people at particular risk from loneliness were identified: Widowed older homeowners living alone with long-term health conditions. Unmarried, middle-agers with long-term health conditions. Younger renters with little trust and sense of belonging to their area.
Feeling lonely can also have a negative impact on your mental health, especially if these feelings have lasted a long time. Some research suggests that loneliness is associated with an increased risk of certain mental health problems, including depression, anxiety, low self-esteem, sleep problems and increased stress.
Psychologists generally consider loneliness to be a stable trait, meaning that individuals have different set-points for feeling loneliness, and they fluctuate around these set-points depending on the circumstances in their lives.
They have found increased levels of loneliness to predict higher levels of neuroticism and lower levels of both extraversion and conscientiousness 15 years later, while only neuroticism at baseline was predictive of later levels of loneliness.
Socially isolated people have an increased risk of cognitive decline such as impaired concentration, memory loss, dementia, and loss of social capacities. They also suffer adverse emotional consequences such as depression, stress, and anxiety. They also feel sick more often and have a shorter lifespan.
Depression, anxiety, sleep disruption and loneliness can be inter-connected and are just some effects that may linger as the quarantine begins to lift. If symptoms persist beyond four months, you may be diagnosed with Post-Traumatic Stress Disorder (PTSD).
Feeling lonely and isolating yourself from the world can be both a cause and a symptom of anxiety. Some people experience anxiety because they feel incredibly isolated. Others feel they need to be alone to reduce their anxiety.
Moving has a host of benefits, including helping you beat the blues of loneliness. Try dance, yoga, or going for a walk, or find an exercise class online. Staying active can help with depression, anxiety, stress, and a host of other things that can come with being lonely.
The reason you have no friends may be because you are shy, uncomfortable interacting with others, or simply don't go places that would lead to meeting new people. You don't have friends may have a lot to do with your mindset.
Causes of loneliness include life changes that lead to social isolation, like moving to a new place, grieving a death, or the end of a relationship. In some cases, loneliness is linked with mental health conditions like depression.
Most notably, researchers found that loneliness rates peak among people in their 20s, and reach their lowest point among those in their 60s. Many people also experience a spike in lonely feelings around their mid-40s. These findings are as confounding as they are surprising, at least initially.
Biologists have shown that feelings of loneliness trigger the release of stress hormones that in turn are associated with higher blood pressure, decreased resistance to infection and increased risk of cardiovascular disease and cancer.
