does flying make your period come early


As a frequent traveler, I have often wondered about the connection between flying and menstrual cycles. I have heard numerous anecdotal stories about women experiencing irregular periods after a long-haul flight. I decided to delve into the science behind this phenomenon to separate fact from fiction.

The Impact of Flying on Menstrual Cycles

When it comes to the impact of flying on menstrual cycles, there are conflicting opinions. Some women claim that flying can make their periods come early, while others believe it has no effect. To understand this better, let’s look at how flying can potentially disrupt the menstrual cycle.

Changes in Circadian Rhythm

One of the reasons behind the potential impact of flying on menstrual cycles is the disruption of the body’s circadian rhythm. Jet lag, caused by traveling across different time zones, can lead to hormonal imbalances, affecting the regularity of menstrual cycles. The body’s internal clock, which regulates hormone production, can be thrown off balance when exposed to rapid changes in daylight and darkness.

Stress and Hormonal Imbalances

Flying can also be a stressful experience for many individuals. Stress triggers the release of cortisol, a hormone that plays a crucial role in the menstrual cycle. Elevated levels of cortisol can disrupt the production of other hormones, such as estrogen and progesterone, leading to changes in the timing of periods.

Factors to Consider

While the impact of flying on menstrual cycles is still a matter of debate, there are several factors to consider when assessing this potential connection. Women’s bodies respond differently to stress, changes in sleep patterns, and environmental factors, making it challenging to draw definitive conclusions.

Individual Variations

Women’s menstrual cycles vary widely, with some experiencing regular, predictable periods, while others have irregular cycles. It is essential to consider individual variations before attributing changes in menstrual cycles solely to flying.

Length and Frequency of Flights

The length and frequency of flights can also play a role in potentially affecting menstrual cycles. Long-haul flights across multiple time zones can increase the likelihood of experiencing jet lag and hormonal disruptions, while short domestic flights may have a minimal impact.

After extensive research and personal experiences, it is evident that flying can indeed have an impact on menstrual cycles. The disruption of circadian rhythms, stress, and hormonal imbalances may contribute to changes in the timing of periods. However, it is essential to recognize the individual variations and other external factors that can influence menstrual cycles. While flying may not directly cause periods to come early, it can contribute to irregularities in some women. As our understanding of the body’s response to environmental changes continues to evolve, it is essential to approach this topic with an open mind and consider the complexities involved.


Q: Does flying always make periods come early?

A: No, flying does not always make periods come early. While some women may experience changes in their menstrual cycles after flying, others may not notice any difference.

Q: Can jet lag affect menstrual cycles?

A: Yes, jet lag caused by flying across different time zones can disrupt the body’s circadian rhythm and lead to hormonal imbalances, potentially affecting menstrual cycles.

Q: How long does it take for the body to adjust after a long-haul flight?

A: The body’s adjustment to time zone changes varies from person to person. It can take several days for the body to fully adapt to a new time zone, during which hormonal fluctuations and disruptions in menstrual cycles may occur.

Q: Are there any specific measures to mitigate the impact of flying on menstrual cycles?

A: Practicing relaxation techniques, staying hydrated, and maintaining a regular sleep schedule before and after a flight can help minimize the potential impact of flying on menstrual cycles.

Q: How can I track changes in my menstrual cycle when traveling frequently?

A: Using a menstrual tracking app or keeping a physical calendar to monitor the timing and duration of periods can help identify any irregularities or changes in menstrual cycles while traveling.
