A recent study has discovered that it is not just what you consume, but at what time you eat that is significant, knowledge which can enhance the health of individuals suffering from jet lag and shift workers. The MRC (Medical Research Council) supported study is the first one to identify insulin as the main signal that aids in communicating the time of meals to the cellular clocks situated across our body, normally termed as the body clock. The study was published in the journal Cell. The research team believed that this superior understanding might lead to innovative ways to ease the ill-health linked with disturbance to the body clock. These can comprise eating at particular times or taking drugs that aim insulin signaling.
The circadian rhythm—also known as body clock—is a 24-Hour biological cycle that takes place independently in every cell of the body, impelling daily rhythms in physiology, from when the person sleeps, to hormone levels, and how the response is for medication. Apparently, the body clock is synchronized with the surroundings by exposure to daytime and the time of meals. This synchrony is imperative for long-term health and it is widely known that disrupting the circadian rhythm with shift work or travel across different time zones can be harmful to health. Prominently, it is thought that having meals at unusual times as often happens during jet lag and shift work, is the main reason for body clock disruption.
On a similar note, recent a study showed that doing exercise in morning or afternoon may change the body clock forward. Seemingly, exercise can change the body clock in humans, through the course and quantity of this outcome based on the time of night or day when people exercise. The study was issued in The Journal of Physiology. These results suggest that exercise can contradict the effects of shift work, jet lag, and other disturbances in the body’s inner clock helping individuals in adjusting to shifted schedules.
