Harvard expert's 5-3-1 rule is the key to a healthy social life
How much time should you spend with your friends?

In a world where we must keep busy to survive, it can be easy to neglect our social lives. This becomes even harder as we age and our friends have families and more responsibilities. Once you hit your 30s, the friends you saw every few days can quickly become people you only see a few times a year.
Friendships need to be nurtured to keep moving forward. If not, one day, our closest friends will begin to feel like strangers. Sadly, this is a common occurrence, and studies show that as people age, their circle of friends becomes smaller and smaller. This is one of the many factors contributing to what's known as the "loneliness epidemic." Studies show that one in three Americans report feeling lonely regularly, and one in four has no social and emotional support at all.
Further, in a world with Netflix, video games, and social media, it can be easy to be entertained without making plans, leaving the house, or spending time with anyone. But that shortcut could lead to waking up one day with very few people in your life. We know we need to get out there and be social, but what’s the correct amount of time we should spend hanging out?

Kasley Killam, a Harvard-trained social scientist and author of "The Art and Science of Connection," has made it easy with her simple 5-3-1 rule, a guideline for evaluating social health. "We need to be intentional about connection, just like we are with exercise and eating healthy foods," Killam told Business Insider.
What is the 5-3-1 rule?
(5) Spend time with FIVE different people a week
A 2022 Harvard Business School study found that the more “diverse” the group we socialize with, the happier we will be. That means we shouldn’t just spend time with our close friends and family members but grab a coffee with a friend from the gym or spend some time with an old friend you haven’t seen in years. As the song goes, “Make new friends but keep the old one is silver and the other’s gold.”
(3) Nurture at least THREE close relationships
Focus on nurturing three friendships every day, whether you text them or make plans to see each other. These are the people at the top of your phone list or who would be your emergency contacts.
(1) Have ONE quality hour of social connection a day
Make time every day to socialize with someone, whether by hopping on a phone call with a family member or going on a walk with a neighbor. "That doesn't have to be all at once," Killam said. " It could be 10 minutes here, 10 minutes there." The important rule Killam says is that the interaction has to be “meaningful.”

Socializing is great for our happiness but can also help us live longer. A study of senior citizens found that the more people socialized, the longer they lived. Those who lived the longest took time to socialize with someone once a day.
Living by the 5-3-1 isn’t just for older people who need to get back into socializing. It’s great for younger people because it can strengthen their relationships and their mental health at the same time. You may be busy these days, but at the end of your life, you probably won’t remember that long day you spent at the office or a random Thursday stuck in traffic. But you will remember that walk you took with your friend when you needed someone to talk to or that night you stayed a little late at your bestie's house making vacation plans.
