According To Some Studies, Having A Sister Makes You Happier And More Optimistic

Having a sister can sometimes seem difficult when you think of all the stupid/girly fights. But growing up with one is so much fun as you can enjoy makeup practice on each other, go shopping, have a girly chat, advice when it comes to dating… The list of things sisters can do together is ENDLESS. But if you have a sister, you already know that.

As for guys, having a sister to pick presents for your partner can be life-saving too 😉

But at times they can be annoying: eating the snacks you saved for later or wearing your favorite pieces of clothing just when you wanted to. According to a study, you should be more grateful to have a sister and forgive her for her flaws.

A research team at De Montfort University in Leicester and Ulster University discovered that having a sister can make you happier.

Wow, like we needed a study to tell us that.


Having at least one girl in the family can make you more optimistic too. They interviewed 571 people aged between 17 and 25 and the researches discovered that people with sisters have a more balanced life.

They are also proven to draw families closer together.

Professor Tony Cassidy, from the University of Ulster, told The Telegraph that people with sisters also have a good mental health.

According to Unilad, he said:

“Sisters appear to encourage more open communication and cohesion in families.

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.”

During the research, some interviewees that came from broken homes claimed that the sisters were the ones supporting each other more during their parents divorce.

Meanwhile the children who had no siblings scored in the middle range for happiness and optimism.

Liz Wright, the co-author of the study, added:

“With only children we found that they had lots of strong communication outside of the home.

“It appears that they have as much social support as those with siblings, but it does not come from within the family.

“If they had interviewed me about my sister, they would have got some very different results.”

Well? Call your sister, tell her you love her. And, what’s the craziest thing you’ve done when you were kids?
