Everything around is us responsible for how well we age. From what kind of food we eat, what kind of lifestyle we lead to what kind of air we breath. Many people want to live longer and healthier, often trying things like special diets or supplements. But would you ever consider paying a lot of money to have your blood's liquid part, called plasma, replaced? This procedure, known as plasma exchange therapy, is becoming popular, especially among the wealthy and those who are into extreme "biohacking" (trying unconventional methods to improve their health). However, the question arises, does it actually help you live longer? A small, recent study published in the journal Aging Cell suggests it might have some anti-aging benefits. However, experts warn that we still need a lot more research to be sure. What Exactly Is Plasma Exchange Therapy? Think of plasma exchange therapy as a "blood cleanse." Here's how it works:Medical staff take blood out of your body.They then separate and remove your old plasma, which contains various substances.This old plasma is replaced with new plasma from a donor or a special solution (usually saltwater and protein).Finally, your "cleaned" blood, with its new plasma, is put back into your body.This treatment has been used for a long time to help with various illnesses, like blood problems, autoimmune diseases (where your body attacks itself), and nerve disorders. However, using it to slow down aging is a very new idea that hasn't been fully proven yet. What the Latest Study Found A recent, small study offers more support for the idea of plasma exchange as an anti-aging treatment. Forty-two healthy adults, with an average age of 65, underwent the procedure multiple times over several months. Some received a regular replacement fluid, while others were given extra immune antibodies. A small group received a fake treatment for comparison. After the treatment, researchers used different ways to measure the participants' biological age—a concept that suggests your body can be physically older or younger than your actual years. The group that didn't get the treatment continued to age normally. However, the plasma exchange group showed some signs of reversal in aging. Those who received plasma exchange combined with immune antibodies saw the biggest effect, appearing biologically 2.6 years younger on average. Those who only had monthly plasma exchange looked about 1.3 years younger. While promising, the researchers are careful to say they don't know for sure if this means people will actually live longer. Does Plasma Exchange Really Work for Longevity? Even though the new study is exciting, it has some important limitations. It was small and relatively short. Also, the idea of biological age itself is still new, and there isn't one perfect way to measure it, which can lead to varying results. Experts also point out that the participants in the study might have made other healthy lifestyle changes, which could have influenced the results. At this point, it's still just a guess whether plasma exchange therapy will truly help people live longer. Many experts agree that while plasma exchange is safe and effective for treating certain diseases, there isn't enough solid information yet to recommend that healthy people spend a lot of money on it just to live longer. Even the scientists who helped create the procedure advise against it for healthy adults right now.
