Other times they drive us bonkers, but overall (most of the time) we love our brothers and sisters. And research shows that the sibling bond is about more than family dinners and spontaneous wrestling matches over the remote. Growing up with a brother or sister may actually have an impact on our mental and physical health, not to mention it can shape who we become later in life. Here, the many benefits of siblings. **Having a sibling may make you more selfless.** [New research](http://onlinelibrary.wiley.com/doi/10.1111/jora.12174/abstract) suggests that having a sibling may help children develop sympathy. Researchers examined the relationship between siblings in more than 300 families and found having a quality relationship with a brother or sister may promote altruism in teens, especially boys. “In our study, most relationships were not as important for boys as they were for girls,” study co-author Laura Padilla-Walker [said in a university release](http://news.byu.edu/archive14-oct-brothers.aspx). “But the sibling relationship was different—they seemed to report relying on sibling affection just as much as girls do. It’s an area where parents and therapists could really help boys.” ([MORE: 30 Secrets Your Body Language Gives Away](http://www.realsimple.com/health/mind-mood/reading-body-language-00000000048262/index.html?xid=time-rs-110414)) **They may improve our mental health.** Some of the same researchers at Brigham Young University found that sisters, specifically, seem to give siblings a mental health boost in ways that parents don’t. [Results](http://news.byu.edu/archive10-aug-siblings.aspx) of a statistical analysis of nearly 400 families showed that, regardless of age-distance, having a sister protected adolescents against feeling lonely, unloved, guilty, self-conscious, and fearful. Even fights help by forming important tools, like how to better control emotion, [according to Padilla-Walker](http://news.byu.edu/archive10-aug-siblings.aspx).

That’s why it should come as no surprise that holding onto a tight relationship with your brother or sister can lead to happiness later in life. [Research](http://ohioline.osu.edu/flm99/fs06.html) shows that older people with living siblings have a higher sense of morale, so bonding with our brothers and sisters isn’t only important as we grow and mature, but may also bring major benefits later in life.

When it comes to fit-inspiration, [43 percent](http://psychcentral.com/news/2011/10/07/family-and-peers-have-big-impact-on-health/30146.html) believe that friends and family have the largest impact on how healthy our lifestyles are. And staying fit together may help grow that sibling bond. Nearly [one third of people with healthy habits](http://psychcentral.com/news/2011/10/07/family-and-peers-have-big-impact-on-health/30146.html) distance themselves from those with less healthy ones.

On average, those with poor social connections died about 7.5 years earlier than those with solid bonds to friends and family. That’s about the same difference in length of life as the gap between smokers and non-smokers. This may be because caring about our friends and family inspires us to take better care of ourselves or it may be because we turn to loved ones to provide us with support when we’re sick or stressed, [_Time_ reports](http://content.time.com/time/health/article/0,8599,2006938,00.html). No matter the reason, keeping that strong connection with our siblings could help us live a longer, happier, and healthier life.
