According to recent surveys<\/a>, 33% of adults report experiencing feelings of loneliness<\/a> at least once per week. These emotions don’t just feel heavy but can actually weigh you down on a biological level, too. While we often think of metabolism as something influenced solely by what we eat or how we move, science is proving that our social connections play a surprisingly significant role in how efficiently our bodies function.<\/p>\n\n\n

This then triggers elevated levels of cortisol<\/a>, your body’s primary stress hormone. “While cortisol<\/a> is helpful in short bursts (e.g., to help you manage short-term stressful events), sustained elevation over time throws off your body’s internal rhythm,” Maniscalco says. When these levels are chronically high, it can result in:<\/p>\n\n\n\n
