"Love is a haven from suffering. When you encounter unpleasant things, staring at your lover's photo can play a positive role." Research The author suggested that people carry a photo of their lover with them, which not only helps to promote the relationship between husband and wife, but also increases happiness and makes people laugh.

Researchers conducted the study. They recruited a group of female volunteers and asked them to look at photos of loved ones, photos of strangers, or other objects when they were depressed, while their brains were scanned using MRI technology.

The results found that when volunteers looked at photos of their loved ones, activity in the middle prefrontal cortex of the brain was active, and this part is closely related to people's sense of security and spiritual comfort. Volunteers also said they felt less pain when seeing photos of their loved ones. Naomi Eisenger, a psychologist who participated in the study, explained that this is because photos of loved ones can comfort and reveal safe information.
