"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.
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.
Long term feelings of loneliness and social isolation can also reduce cognitive skills, such as the ability to concentrate, make decisions, problem-solve, and even change negative self-beliefs. And it can ultimately lead to depression.
While social interactions are crucial to certain areas of brain activity, time alone is necessary for our brains to unwind and recharge. Dr. Sherrie Bourg Carter explains, “Constantly being 'on' doesn't give your brain a chance to rest and replenish itself.
Loneliness was associated with higher rates of depression, anxiety, and suicide. Loneliness among heart failure patients was associated with a nearly 4 times increased risk of death, 68% increased risk of hospitalization, and 57% increased risk of emergency department visits.
One of the greatest benefits of spending time alone is how it helps you develop a better understanding of who you are. The more you know and understand yourself the more likely you are to do things that you love, learn things that interest you and spend time with people who make you feel good.
When you feel lonely, you get more defensive. You focus more on self-preservation even though this is not done intentionally. Completely unbeknownst to you, your brain is focusing more on self-preservation than the preservation of those around you. This, in turn, can make you less pleasant to be around.
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.
Living alone gives you the opportunity to explore your true self and develop a sense of being comfortable in your own skin. This might be the simple act of being comfortable in your own company. Or being able to spot what triggers negative feelings and (most importantly) what you can do to counteract them.
Being alone can help you build mental strength.
We're social creatures, and it's important for us to have strong connections with other people. But solitude is essential to building mental strength.
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. We can hypothesize that, similarly, loneliness is associated with the pain matrix.
Vivek Murthy, the US surgeon general, recently warned that “being socially disconnected” has a similar effect on mortality as smoking up to 15 cigarettes a day. This statement was widely reported in the media, including in the Washington Post, the Times and the Daily Mail.
Loneliness and isolation can be as harmful to your health as smoking up to 15 cigarettes a day, according to a new report from the Surgeon General.
There are different types of loneliness: emotional, and social and existential loneliness.
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.
On the general scale, women have reported having higher levels of loneliness than men. Except for one category: single men are the lonelier group compared to single women. Women are more socially minded and are therefore able to better maintain close relationships than men.
While child experts typically agree that 11 or 12 years old is an appropriate age to stay home alone for a few hours, there are a number of factors to consider. It is important to recognize that the right time will vary by family, so trust your instincts.
Safety & sickness. Problem: Being sick, having an accident, or dealing with a break in when you're alone can be really scary.

Loneliness can affect your health in lots of ways. You may not be able to get out to buy healthy foods - or you may not have the motivation to cook for one. And not getting enough mental stimulation increases the chance of depression and dementia.
An introvert's brain responds to stimuli differently than an extrovert's brain. You're at your best or feel healthiest when you're alone because this is how you recharge and replenish. So, it makes sense that you would spend a lot of time by yourself. We all want to feel healthy, refreshed, and at our best.
They believe that spending time alone can be good for creativity, self-insight, self-development, relaxation, and spirituality. One of the most important determinants of whether time alone is a good experience or a fraught one is whether you choose to be alone.
