With the arrival of summer and holidays, many women notice changes in their menstrual cycle: delay, advance, different flow or even temporary absence of menstruation. The question is common, after all, can heat and disruption of routine really interfere with the functioning of the body?

According to gynecologist Dr. Ana Paula Fonseca, these changes tend to be more frequent than one might think and, in most cases, they do not indicate a health problem. “The menstrual cycle is very sensitive to lifestyle. Changes in sleep, diet, stress levels and even time zones, common during travel and vacations, can directly impact hormonal regulation”, he explains.

During the holidays, it is common to sleep and wake up later, change meal times and indulge in excesses, such as consuming more sugar, alcohol and food ultra-processed. All of this influences the hormonal axis responsible for ovulation.

“The body works at its own pace, guided by hormones. When the routine changes suddenly, the body can ‘take time’ to adapt, and this is reflected in the menstrual cycle. It is not uncommon to see delays or shorter cycles during this period”, explains gynecologist Ana Paula Fonseca.

Summer can interfere with menstruation

Summer also brings warmer temperatures and often increased physical activity. The combination can lead to dehydration and small changes in metabolism, which influence hormone production.

“Excessive exercise, especially when associated with low caloric intake, can temporarily suppress the ovulation“, highlights Dr. Ana Paula, who adds: “In other women, intense heat can intensify symptoms such as bloating, cramps and a feeling of heaviness”.

When is irregularity a reason for attention?

Despite being common, the gynecologist warns that not every change should be ignored. “If the irregularity persists for more than two or three cycles, is accompanied by intense pain, heavy bleeding or prolonged menstrual absence, it is essential to see a gynecologist”, he advises.

She reinforces that women with conditions such as polycystic ovary syndrome (PCOS)endometriosis or thyroid disorders tend to feel the effects of routine changes even more.

Can you avoid clutter in the cycle?

Maintaining some basic care can help your body get through the summer with more balance. “Trying to preserve your sleep schedule, maintaining a minimally balanced diet, hydrating yourself well and not overdoing it to extremes already makes a lot of difference”, recommends the specialist.

Gynecologist Ana Paula Fonseca reminds us that “holidays are important for physical and mental rest. changes in the cycle can happen and, most of the time, they are transitory. The most important thing is to observe the body and not normalize persistent signs of imbalance.”
