Could reminiscing alleviate your headache, suggests a recent study.
You may be tempted to reflect on more peaceful periods during the current news climate.
Researchers suggest that looking at old photos and videos can reduce brain activity and alleviate common aches and pains through feelings of nostalgia.
Participants experienced reduced perceptions of pain, particularly at low intensities, while feeling nostalgic, according to a report. The study linked this lack of pain to decreased activity in two pain-related brain regions.
Perhaps you can alleviate your headache by browsing through old photo albums or streaming a childhood TV show on Netflix.
A recent study, carried out by psychologists and neuroscientists from the Chinese Academy of Sciences in Beijing, was published in the Journal of Neuroscience. The study involved participants being connected to an fMRI machine, which measures brain activity, and shown a series of 26 nostalgic images, including old cartoons, schoolyard games, and popular candy.
The participants were exposed to varying levels of pain using a heat generator on their right forearm. Their brain activity was compared to a control group that viewed images from modern-day life that did not evoke feelings of nostalgia.
According to a study, individuals who viewed childhood photos reported lower levels of pain and exhibited decreased activity in two brain regions associated with pain: the left lingual gyrus and parahippocampal gyrus.
Researchers have long observed that nostalgia can reduce individuals' perception of physical pain, but the scientific explanation behind it was unclear. A 2012 study by psychologists at Sun Yat-Sen University in Guangzhou, China, found that participants in a state of nostalgia were able to hold their hand in a bucket of ice water for a longer period of time compared to participants asked to think about an ordinary event.
The Beijing-based team has discovered that the thalamus is a crucial link between nostalgia and pain, potentially providing an analgesic modulatory mechanism for nostalgia.
The same areas of the brain that trigger feelings of nostalgia also contribute to pain.
