[Summer Outing Season Approaches] 'Anticipatory Anxiety' Due to Irregular Menstruation Hits Summer Leisure Hard! Over 14 Days a Year 'Not Enjoyed', Travel and Dates Canceled on Average 3 Times a Year

A profound impact of irregular menstruation on plans, outings, and enjoyment has been revealed by the 'Loss of Patience with Irregular Menstruation Fact-Finding Survey 2026' (target: 628 women aged 18 to 49 with concerns about irregular menstruation), conducted by 'Clinic For Group' (hereafter referred to as Clinic For), which provides in-person and online medical consultations.

The upcoming summer season sees an increase in travel and leisure plans. Summer, in particular, is a season where the psychological burden is highest for women with irregular periods, as activities where the timing of menstruation directly affects schedules, such as going to the beach, pools, and long-distance travel, increase. However, it was found that many women with irregular periods not only cancel their plans altogether out of anxiety of 'not knowing when it will come,' but even if they don't cancel, they fall into a state of 'not being able to truly enjoy' themselves.

Survey Result Topics
- Even on days when plans were not canceled, an average of 14.2 days a year were 'not truly enjoyed'
- An average of 3 plan cancellations a year, such as travel, dates, and work-related, due to irregular menstruation
- The biggest problem caused by irregular menstruation is 'difficulty in making plans'. Furthermore, the disturbance of the cycle due to the 'summer heat' becomes a hurdle for outing plans

Survey Result 1: Even on days when plans were not canceled, an average of 14.2 days a year were 'not truly enjoyed'
It was found that the number of days when women felt they 'couldn't truly enjoy' or 'couldn't concentrate' due to anxiety about irregular periods, even on days they didn't cancel plans, reached an average of 14.2 days a year.
This suggests that even during anticipated plans like traveling, lunch with friends, or during meetings, the constant anxiety of 'when will it come' lingering in their minds causes a state of 'being there but not being present' to be repeated throughout the year.

Survey Result 2: An average of 3 plan cancellations a year, such as travel, dates, and work-related, due to irregular menstruation
It was found that the total number of times plans were 'abandoned, canceled, or postponed' due to irregular menstruation in the past year reached an annual average of about 2.8 times (about 3 times) per person.
In particular, cancellations and postponements of travel, leisure, and hot springs amount to 1.0 time a year, affecting plans concentrated in the upcoming leisure season. The reality has been highlighted that women are canceling anticipated plans due to irregular periods, with comments like 'It is difficult to make plans for pools or hot springs' and 'I cannot decide on travel dates.'

Survey Result 3: The biggest problem caused by irregular menstruation is 'difficulty in making plans'. Furthermore, the disturbance of the cycle due to the 'summer heat' becomes a hurdle for outing plans
When investigating the 'problems caused by irregular menstruation' among women who are aware of having irregular periods, the most common response was 'I can't predict when it will come, making it difficult to make plans (70.1%)'. It suggests that more than 70% of women feel stress in managing their schedules for daily life and leisure due to the anxiety of not knowing when their period will start.
Furthermore, there were results regarding factors specific to the upcoming season. To the question, 'Have you ever experienced your menstrual cycle being disturbed or irregular periods worsening at the timing of "environmental changes or life events"?', about 1 in 5 people (21.8%) answered, 'I have experienced a disturbed menstrual cycle or worsening of irregular periods due to a decrease in physical strength caused by summer heat or summer fatigue.'
This suggests the risk that while already burdened with the anxiety of 'not knowing when it will come', the combination of autonomic nervous system disturbances and physical decline caused by the severe heat and temperature differences of summer can make the menstrual cycle even more unstable. Ahead of the full-fledged leisure and outing season, the impact on schedules and the psychological burden of 'maybe not being able to enjoy' can be said to be a season where it is easily heightened further.

Doctor's comment from Clinic For regarding measures against irregular menstruation
This survey reveals a pressing reality that irregular menstruation is not just a poor physical condition, but it makes women give up 'anticipated plans' such as travel and appointments with friends an average of 3 times a year, and makes over 14 days a year 'days that cannot be truly enjoyed' even when they could act. Summer, in particular, is a season where leisure activities that are directly linked to the presence or absence of menstruation, such as the beach, pools, and travel, are concentrated.
Behind irregular menstruation, there are various factors such as daily stress, lack of sleep, and temporary physical disturbances accompanying environmental changes.
