Jet lag after a long trip? Study Explains What Your Body Might Be Going Through

Jet lag is one of the disadvantages of long trips. While crossing multiple time zones has its benefits when traveling to new countries and exploring other corners of the world, the disorientation and dizziness after traveling too long can ruin the excitement (at least for a few hours or days).

The study examined how even the smallest time differences can affect the body. Jet lag is often associated with long journeys and multiple time zone changes. But sometimes even minor problems can make us feel unwell, even if only temporarily.

Why does jet lag occur?

The human body operates according to a circadian rhythm that regulates sleep patterns, hormone production and even overall metabolism. It is controlled by the suprachiasmatic nucleus, a tiny area of the brain that responds to environmental influences such as light-dark cycles to adjust the body’s rhythm accordingly.

Findings of the study:

The study was conducted on 14 participants (8 men and 6 women) who were asked to shift their daily routine by five hours. The research team monitored his routine, including meal times, light exposure and sleep schedules. Their metabolism, including the time it takes for the body to process food, changes in blood sugar and fat levels, and energy burning were recorded.

The results showed that just five hours of shift work can affect a person’s daily routine. Slow digestion, altered blood sugar levels and a shift in metabolism were noted. Participants also demonstrated lower efficiency in producing heat from the foods consumed.

Can the body adapt to the new schedule?

However, her body adapted to the new schedule within 48 to 72 hours and showed remarkable flexibility. This further explains how people adapt to new time zones within a few days. However, the results showed the impact that frequent time shifts have on health and how they can affect daily metabolism. While the body gets used to it, making it go through the ordeal repeatedly may not be ideal.
