A new study has found that people feel the most lonely during their late 20s, their mid-50s and their late 80s.
Three in four people involved in the study said they experienced moderate to high levels of loneliness 鈥� which is troubling because even moderate loneliness can lead to in physical and .
The researchers, who published their study in the journal on Tuesday, wrote their findings 鈥渦nderscore major challenges for society.鈥�
Dr. Dilip Jeste, the study鈥檚 lead author and a professor of psychiatry and neurosciences at the University of California, San Diego, said the higher levels of loneliness in people in thier late 20s and 50s surprised his team.
鈥淭he late 20s are a period of stress because of the need to make some major life-changing decisions,鈥� he told CTV News Channel. During this time, he said people experienced changes to their jobs and where they lived.
Other major decisions included settling on a long-term partner, deciding whether to have a child or to continue school. And the stress from these decisions could increase loneliness, Jeste suggested.
鈥淵ou鈥檙e also competing with peers 鈥� so you feel that you are not doing as well as you should be. That鈥檚 what makes it stressful,鈥� he said, noting he didn鈥檛 think social media use was a primary cause of their loneliness, as other studies have suggested.
But more research was needed to pin down exactly why people felt lonely, Jeste said.
How the study worked
Researchers looked at 340 San Diego County residents between the ages of 27 and 101 and found that men and women felt equally as lonely.
Factors that influence loneliness included whether people lived alone or what their overall mental well-being was.
Jeste stressed that being lonely didn鈥檛 necessarily mean that a person was alone or socially isolated.
Instead, loneliness meant experiencing a 鈥渟ubjective feeling of distress.鈥� In other words, loneliness stemmed from a person realizing the relationships they have, might not be the ones they need.
鈥淚 may have two friends but that鈥檚 all I desire and I won鈥檛 feel lonely. But on the other hand, I may have five friends but if I desire ten friends, then I鈥檒l feel lonely,鈥� he explained.
Getting older means seeing more parents, friend die
Jeste called the mid-50s a 鈥渢ime of mid-life crisis鈥� because this was typically when people began to see their parents and friends die.
鈥淵ou realize that life is finite,鈥� he said, which contrasts a person in their 20s who may feel like they鈥檙e 鈥済oing to live forever.鈥�
He said when people are in their 50s they can 鈥渟tart having physical problems for the first time.鈥� This can include being diagnosed with arthritis, high-blood pressure, diabetes and the onset of menopause.
Jeste said feelings on loneliness only get worse as people aged, which made the third peak of loneliness in the late 80s less of a surprise.
鈥淚 know loneliness increased with old age, especially after the loss of a spouse or friends,鈥� he said.
Being wiser could decrease loneliness
The research also found that people with higher levels of wisdom would feel less lonely and vice-versa, Jeste explained to .
He and his co-authors broke down the trait of wisdom into six different categories which included empathy, how they managed emotion and their ability to make quick, effective decisions.
The study suggested personality can influence how loneliness develops and how long it will last. Researchers suggested loneliness can be tweaked through changes to their behaviour through things like therapy.
鈥淏uilding a wiser society may help us develop a more connected, less lonely, and happier society,鈥� the study said. But it noted the relationship between wisdom and loneliness needs to be further examined.
