A large study shows changes in the brain scans of lonely people in the area involved in imagination, memory, and daydreaming.
- A study of 40,000 participants shows specific signatures in the brain scans of lonely people.
- Loneliness is linked to variations in grey matter volume and connections in the brain default network.
- This area of the brain is connected to the use of imagination, memory, future planning, and daydreaming.

MRI scans show that hunger and loneliness cause cravings in the same area, which suggests socialization is a need.
- A new study demonstrates that our brains crave social interaction with the same areas used to crave food.
- Hungry test subjects also reported a lack of desire to socialize, proving the existence of "hanger."
- Other studies have suggested that failure to socialize can lead to stress eating in rodents.
People sometimes crave socialization, literally.<p> Forty participants underwent 10 hours of either social isolation or fasting before being placed in an MRI machine. Those who fasted had their brains imaged while viewing pictures of food; those emerging from isolation viewed photos of socializing people. <strong><br> <br> </strong>The areas of the brain related to hunger pains, reward, and movements, the substantia nigra pars compacta and ventral tegmental area (SN/VTA), are also associated with cravings for food or addictive substances. When those who fasted viewed images of food, these regions of their brains lit up. Most interestingly, the same brain regions lit up when those who had been isolated for 10 hours saw pictures of other people socializing. <br> <br> Test subjects also filled out questionnaires during and after the fasting and isolation periods. Not only did this confirm that people felt cravings for what they had missed, but that the effect was similar in both cases. </p><p>They also showed that very hungry people were less responsive to images of socializing, suggesting that "hanger," the state of being irritable as a result of hunger, is a demonstrable <a href="https://www.insider.com/loneliness-and-hunger-have-similar-effects-on-the-brain-study-2020-11" target="_blank" rel="noopener noreferrer">state</a>. </p>
How can I use this information? I’m asking for a friend.<p> The obvious takeaway is that it is perfectly normal to feel a need for interaction with others after an extended bout of isolation. Our brains treat some form of interaction as a basic need that must be met. While not shown as clearly in humans, not getting these needs often drives mice to <a href="https://pubmed.ncbi.nlm.nih.gov/29334694/" target="_blank" rel="noopener noreferrer">stress ea</a><a href="https://pubmed.ncbi.nlm.nih.gov/29334694/" target="_blank" rel="noopener noreferrer">t</a>, a finding that makes a great deal of sense in light of these new findings. <br> </p><p>Exactly how we can meet the need for socialization outside of just meeting up with people (a tricky proposition at the time of writing) remains up for debate. Anybody who has tried a Zoom party during the pandemic can attest to it just not being as nice as seeing friends in person. <br> <br> The study's authors are aware of this issue and note that:<br> <br> "A vital question is how much, and what kinds of, positive social interaction is sufficient to fulfill our social needs and thus eliminate the neural craving response. Technological advances offer incessant opportunities to be virtually connected with others, despite physical separations. Yet, some have argued that using social media only exacerbates subjective feelings of isolation.<sup>"</sup><br> </p><p>Unfortunately, the study cannot offer us an answer to this question just yet. </p>
Like always, there are limitations to this study.<iframe width="730" height="430" src="https://www.youtube.com/embed/sgxMsgDWnAU" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p> This study involved 40 participants. While its essential finding is likely to be generally applicable, exactly how applicable it is to the broader population cannot be known with certainty from such a small group. The participants were also healthy, well-connected young adults who might react to various problems differently than other demographic groups. </p><p>Their tendency to do so while being the focus of endless studies on psychology is a well-recorded problem. <br> <br> Likewise, the fact that the participants knew they would only be isolated for 10 hours may have impacted how they reacted to the isolation—it is often easier to endure something when you know precisely when it will end. </p><p>Getting around that in future experiments may prove impossible. From an ethical standpoint, it would be difficult to structure an experiment on humans predicated on the idea that they will be kept isolated from all social interaction indefinitely. <br> <br> Lastly, while all of the participants were quite hungry after 10 hours, there were enough variations in how lonely people felt after isolation to suggest a more significant variance in need for socialization than in demand for food. While this seems obvious, we all know both introverts and extroverts; it does make it more challenging to determine how much social interaction counts as a "need" that the brain craves just as it craves food. </p><p>As usual, more research is needed.</p><p> The idea that humans are social animals existed long before modern neuroscience was possible. Now, we can see exactly what happens in the brain when we can't socialize. While the final word on the subject is still to be said, it might be time to give a friend a call. </p>
Different kinds of loneliness – Having poor quality relationships is associated with greater distress than having too few
According to a new study, there are 4 different types of loneliness.
Loneliness not only feels bad, experts have characterised it as a disease that increases the risk of a range of physical and psychological disorders. Some national prevalence estimates for loneliness are alarming. Although they can be as low as 4.4 per cent (in Azerbaijan), in other countries (such as Denmark) as many as 20 per cent of adults report being either moderately or severely lonely.
Thanks in no small part to the digitization of our social lives, depression is becoming a bigger and bigger issue in western societies. So how do we reverse it?
Thanks in no small part to the digitization of our social lives, depression is becoming a bigger and bigger issue in western societies. In the space of just one generation, we've closed ourselves off and now spend more time in front of screens — on average, 10 hours a day according to a Neilsen report — than we do with our loved ones. Author and journalist and author Johann Hari explains that this isn't at all how the human species is supposed to behave. He suggests more actual face time with people, more community, and above all: becoming the social creatures that we have been for millennia. Johann's new book is the fascinating Lost Connections: Uncovering the Real Causes of Depression – and the Unexpected Solutions.
Time on your own means time to tell the difference between right and wrong.
In 1840, Edgar Allan Poe described the ‘mad energy’ of an ageing man who roved the streets of London from dusk till dawn. His excruciating despair could be temporarily relieved only by immersing himself in a tumultuous throng of city-dwellers. ‘He refuses to be alone,’ Poe wrote. He ‘is the type and the genius of deep crime … He is the man of the crowd.’
