Sisters are great, but a new study has shown they might be even greater than we initially thought! The believes that simply having a sister can make you happier and more optimistic.
“Sisters appear to encourage more open communication and cohesion in families. However, brothers seem to have the alternative effect.” the study says.
“Emotional expression is fundamental to good psychological health and having sisters promotes this in families.”
“It could be that boys have a natural tendency not to talk about things. With boys together it is about a conspiracy of silence not to talk. Girls tend to break that down.”
The study added that there are added effects of having a brother, but they were just less likely to demonstrate pro-social behaviours.
"Sibling affection from either gender was related to less delinquency and more pro-social behaviours like greater kindness and generosity, volunteering and helping others."
