The immune system becomes the same when we are together

When you are in a relationship, you can also share your habits, diet, sports, sleeping time with your partner. And according to a new study, scientists also believe that the immune system of two people will become the same when living together.

Each person's immune system is unique. They differ in the number and type of immune cells, as well as the activation states. This diversity explains the question of why the virus is the same, but people only feel tired in one afternoon, others are bedridden for several days.

Professor Adrian Liston at Catholic University of Leuven (Belgium) and colleagues analyzed blood samples taken from 670 healthy people, aged between 2-86. For each person, the expert team conducted a count of immune cells, in all 54 different triggers. Next, they selected a quarter of the volunteers and continued to sample the test for 6 months. After this time, Liston's group discovered something quite interesting, the immune system of people living together, became remarkably similar."The rate of change is up to 50%, showing that the effect is extremely deep," Liston said.

Individuals in the same relationship tend to adopt a diet as well as a similar lifestyle, a phenomenon known as the "spousal concordance" . For example, the husband has less alcohol and his wife will drink less. In addition, according to Professor Liston, there may exist some aspects of the environment , making a couple's immune system become the same when they live together. Specifically, environmental exposure is likely to affect the immune system, and two people living together have similar risks. Holden Maecker from Stanford Medical University (California, USA) thinks that the immune system of married couples can be shaped , by sharing viruses with each other.

Accordingly, people living together seem to also possess intestinal bacteria systems (which play a very important role in immune function). This similarity can be affected by bacteria found on the floor, dusty, or perhaps because of young children in the house. All couples participating in this study were both parents, so children are also considered a bridge of bacteria. Infants often breastfeed, and bacteria follow that, 'migrate' back and forth. And when the father kissed their son, the bacterium continued on to him.

"It's hard to say if this immune convergence is good or bad for your health," said Valerie O'Donnell of Cardiff University (UK). "It depends on how they converge . " Some changes can make a person more susceptible to infection, but may also enhance their defenses, compared to others. "We really have no way to say that someone owns a" good "immune system , " Maecker said.
