For any only children or owners of brothers out there, having a sister is truly epic, and now that statement is backed up by science. 

Okay, you may have clothes and makeup stolen from your room on the regular and you may have to be the gatekeeper of many a cover story to your parents, but having a sister to confide in scientifically makes women happier people. 

Findings by De Montfort University and Ulster University found that sisters encourage open communication about each others emotions, which leads to elevated moods and feelings of happiness.

'Sisters appear to encourage more open communication and cohesion in families,’ Professor Tony Cassidy explained to The Telegraph.

‘However, brothers seem to have the alternative effect.'

'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.’

So that solves it – having sisters officially improves your quality of life (even if it doesn't always feel that way)
