Loneliness is contagious – and here's how to beat it

By Olivia Remes, University of Cambridge

Loneliness is a common condition affecting around one in three adults. It damages your brain, immune system, and can lead to depression and suicide. Loneliness can also increase your risk of dying prematurely as much as smoking can – and even more so than obesity. If you feel lonely, you tend to feel more stressed in situations that others cope better in, and even though you might get sufficient sleep, you don’t feel rested during the day.
