One study, conducted in partnership by researchers at the University of California (UC) at Davis and San Francisco, USA, concluded that the practice of meditation influence in improving the immune system.

The researchers explain that the increased activity of the enzyme telomerase is responsible for this influence. The study is the first to associate the well-being of the enzyme, responsible for long-term health of the cells.

The effect can be attributed to physiological changes that improve people's ability to handle stress and maintain a sense of well-being.

"We found that meditation and promotes positive psychological changes that meditators with better psychological outcomes had higher levels of telomerase," says Clifford Saron, a research associate at UC Davis.

The researcher adds that "meditation can improve the psychological well-being and in turn, these changes are related to telomerase activity in cells of the immune system, which has the potential to promote longevity of these cells."

Telomerase is an enzyme that can rebuild and lengthen telomeres. Other studies suggest that the enzyme activity may be associated with psychological stress and physical health. Telomeres are DNA sequences at the end of chromosomes, which tend to get shorter each time a cell divides. When the telomeres decrease to a critical length, the cell can not divide properly and eventually die.

Using statistical modeling techniques, the researchers concluded that telomerase activity was high due to the beneficial effects of meditation on perceived control.
