Flying While On Your Period
All You Need To Know
Does flying affect menstruation?
Are delayed periods after a trip only a myth, or can travelling actually affect your menstrual cycle? It isn’t uncommon for the menstrual cycle to be disrupted by flying, so there is no reason to worry if your flow if different as a result of flying.
To your body, 'stress' is anything that throws its systems out of their usual routine and subtle changes to your daily pattern, such as waking up really early one day and then sleeping late the next night, or getting anxious about an upcoming trip, can have a small impact on your melatonin and cortisol levels — the two primary hormones that control your cycle. When the levels of either melatonin or cortisol changes, your ovulation schedule can shifts, meaning your period might arrive later or earlier than expected.
This is even more true if you’re travelling to a different time zone or country — one of the biggest causes of changes in the menstral cycle when flying is the result of changing time zones. Jetlag can wreak havoc on your cycle, impacting you physically in many different ways. Jetlag can make it had to fall asleep and maintain your sleep routine, and cause digestive issues and disorientation.
It takes time for your body tries to adjust, can this can all impact your cycle.
Should I be worried if my menstrual cycle changes after flying?
It is normal for the menstrual cycle to change slightly after travelling, but if you have any concerns, speak to your doctor.
It is important to note that when your menstrual cycle changes, this can affect your fertility, meaning you may become fertile at a different time during the month. For women who take the pill as their form of contraception, be sure to consult your doctor before you travel to discuss the timing of your contraception while away.
