University of Zurich researchers have created a spray that can relieve people of shyness, and help them socialise with others.
The spray is very easy to use, and an individual can boost self-confidence just by squirting it up the nose.
The researchers say that the spray harnesses the powers of a feel-good hormone called oxytocin, a neurotransmitter in the brain that is involved in social recognition and bonding.
The mammalian hormone is produced naturally by the body when a person is in love, and it also induces labour in pregnant women. The spray contains a synthetic version of it, created in the laboratory.
University researcher Dr Markus Heinrichs says that the spray was found to "dramatically" change the behaviour of 70 adults during a study. He says that all study participants had stopped feeling anxious, and started to engage better with others in the group.
