Circadian rhythms, popularly known as the “body clock”, plays an important role in understanding our body’s internal system. It is a natural timepiece to remind us of the things we need or activities that we should do for our body.

These natural cues help people achieve a balance in biological mechanisms such as eating and sleeping. They also help regulate humans’ “self-drive” mechanisms such as breathing, heartbeat, and body temperature, as reported in the Medical News Today.

Meanwhile, a study conducted by a team of investigators from the Douglas Mental Health University Institute and the Université de Montréal in Canada showed that the body’s immunity response may differ depending on the time of day. This is reportedly because a person’s circadian rhythms affects his or her body mechanisms including those that are related to immunity.

Their study, according to the co-author, Nathalie Labrecque, shows that T cells are more prone to be activated at certain times of the day.

“Identifying the mechanisms through which the biological clock modulates the T cell response will help us better understand the processes that regulate optimal T cell responses,” she added.

Their findings was first published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) last September 16.

Researchers believed that their research would help in improving vaccination strategies. The study also suggest to professionals to consider the time of day to maximize the use of vaccines.
