A Swedish town encourages its residents to say hello to one another.

A small gesture can help a sad person to go on in their life even saying hi. The Swedish town of Lulea, which has a population of 80,000 people, has initiated a campaign to encourage its residents, who are said to be introverts, to start chatting to each other.

In a social media video, residents of Lulea, located 150 kilometers south of the Arctic Circle, with stern faces suddenly light up when they meet a passer-by who greets them.

The clip is accompanied with the following text: "Saying hi to your neighbors is a small thing but research shows that it can contribute to social bonds and has a positive impact on health, safety and well-being."

Since October 31, a campaign promoting social connections has been displayed on buses and buildings throughout Sweden. The four-week program attempts to build relationships and urge individuals to be more introspective.

According to surveys, persons between the ages of 16 and 29 are feeling more lonely. As the modern urban lifestyle has resulted in less possibilities for everyday connection, the campaign attempts to establish social bonds and encourage individuals to greet one other more frequently.
