If you’re that sister whose clothes get stolen every time by your other sister, or she might just get on your nerves, this title most likely made you roll your eyes. But at the end of the day, they’re the ones you go to if your day wasn’t the best one, and they can be the ultimate best friends. And actually there are studies to prove this.
A study made by Brigham Young University in 2010 and published in the Journal of Family Psychology show that sisters can actually boost your mental health, self-esteem “feeling lonely, unloved, guilty, self-conscious and fearful”, regardless if she’s younger or older then you.
The study involved 395 families with more than one child, including at least one between the ages of 10 and 14. The adolescent child was videotaped while answering questions about a sibling closest in age. Researchers then followed up with the families a year later.
“What we know suggests that sisters play a role in promoting positive mental health,” Alex Jensen, assistant professor in the School of Family Life at BYU, told Motherly, “and later in life, they often do more to keep families in contact with one another after the parents pass.”
Most likely brothers out there are feeling kind of left out here, but researches have been made in this area too, and they have found that affectionate siblings have a positive impact on each other, no matter their age, gender, or the years between the siblings.
