Losing a loved one is a difficult challenge in life, but according to new research, the impact of losing a loved one could cause more than just emotional pain. In a new study from Columbia University's Mailman School of Public Health, experiencing the death of a loved one could actually accelerate the aging process at a biological level, potentially setting the stage for earlier onset of age-related health problems. Research found that people who lost two or more close family members, including parents, partners, siblings or children, showed signs of accelerated aging as compared to those who had not lost any loved ones. The effects were seen in people in their 30s and 40s, suggesting that the impact of grief on the body can happen much earlier than researchers originally thought.

“Our study shows strong links between losing loved ones across the life course from childhood to adulthood and faster biological aging in the U.S.,” says lead author Dr. Allison Aiello, a professor of epidemiology at Columbia University, in a statement. The study found important information that is useful for health professionals in the future and gives a better understanding of how life experiences impact our long-term well-being. Nearly 40 percent of adults who were surveyed had experienced at least one significant loss by the time they were in their early 40s. This highlights just how common losing a loved one is and points out the need for a strong support system for those who are dealing with grief. “We still don’t fully understand how loss leads to poor health and higher mortality, but biological aging may be one mechanism as suggested in our study,” notes Dr. Aiello. “Future research should focus on finding ways to reduce disproportionate losses among vulnerable groups. For those who experience loss, providing resources for coping and addressing the trauma is essential.”
