The molecules produced by the blood after exercise make the brain younger.

Recently, Science magazine, an internationally renowned journal, published an article entitled "Blood factors transfer effects of exercise on neurogenesis and cognition to the old brain".
reported that a cytokine produced in the blood after exercise can promote nerve regeneration in the elderly brain and improve cognitive ability.
researchers from the University of California in California analyzed the composition of the blood of regularly moving mice and found that a rare protein, Gpld1, was closely associated with improved memory in mice.
results were similar to those in animals, and Gpld1 levels were generally higher in the blood of older people who exercised regularly.
, the researchers used genetically modified technology to increase the expression of Gpld1 in mice and found that it protected the brain's cognitive abilities in aging mice.
although the mechanism for regulating Gplld1 is not yet known, the authors note that developing drugs that simulate the molecular effects could help improve brain conditions for people who lack exercise for a variety of reasons.
