Recent research reveals that during the holiday season, a time traditionally associated with family gatherings and joy, loneliness is on the rise worldwide, reported across the United Kingdom, European Union, Japan, Canada, Australia, the United States and other countries.
According to the Organisation for Economic Co-operation and Development’s (OECD) 2025 Social Connections and Loneliness Report, up to 14% of people in member countries feel lonely most or all of the time. In the U.S., the “Stress in America 2025” report from the American Psychological Association shows that half of adults report signs of loneliness, including emotional disconnection and isolation.
“No matter the part of the world, holidays come with a lot of ‘shoulds’ and unrealistic social expectations of happiness and connectedness. But in reality, many people naturally struggle with those, and that doesn’t suddenly disappear during the end-of-year festivities,” explained Dr. Hannah Nearney, clinical psychiatrist and U.K. medical director at Flow Neuroscience, a company that developed brain stimulation treatment for depression.
Some of the main reasons behind loneliness during the festive season are distance from family and strained relationships.
This Christmas, 14 million Americans will spend it alone, with almost half due to conflict or being far from family, reports AMFM (A Mission for Michael), while OECD finds that the frequency of in-person interactions with friends and family has been declining over the past decade.
“The festive attributes of December, like Christmas traditions, songs and movies, trigger the brain to think of family. Because Christmas is so commercialized, even different cultures are affected,” said Dr. Kultar Singh Garcha, National Health Service general practitioner and chief medical officer at Flow Neuroscience.
“If the family is far, someone has passed or there’s a conflict, all the emotions come out: grief, anger, disappointment and loneliness, of course.”
Stress, including financial, can amplify the feeling of loneliness. According to the 2025 “Festive Feeling” study from the South African Depression and Anxiety Group, more than one in three people feel tired “for no good reason” and lonely this holiday season.
OECD adds that people typically facing financial stress, such as those unemployed or with low incomes, are nearly twice as likely to report feeling lonely.
“Stress can impair the functioning of the pre-frontal cortex, which is essentially the brain’s control center for executive functioning. When that happens, it’s much harder to regulate emotions or make considered decisions, thus social cues can feel harsher. Small disconnections can feel bigger, strengthening the sense of isolation,” explained Nearney. “Financial stress is especially intense: it pushes the brain into survival mode, and social connections become much less of a priority.”
To those struggling with loneliness this holiday season, clinicians recommend fostering meaningful connections and supporting emotional well-being.
“Focus on nurturing relationships that you already have and set boundaries with difficult relatives. If you can’t meet loved ones in person, organize regular video calls. Also, small acts of kindness can help you feel more connected to your community: simply compliment someone or offer help with heavy bags,” said Garcha. “If you’re persistently struggling with stress or low mood, not just loneliness, consider seeking professional help. It can be psychotherapy, support groups or clinician-guided mental health tools like brain stimulation.”
