Viktoryia LuhakovaDuring the warmer months, many women notice changes in their menstrual cycle: variations in flow, more intense pain, increased fatigue, or mood swings. But what’s actually happening? And how does the female body react to high temperatures?
To clarify this topic, we interviewed Dr. Carmen Nava, gynecologist at Smart Clinic Oriocenter and Le Due Torri, part of the Gruppo San Donato medical network, a reference point for everyday health care.
How heat affects the menstrual cycle
Extreme heat can have an indirect impact on the menstrual cycle. High temperatures, combined with dehydration and disrupted sleep patterns typical of summer, may alter the body’s normal hormonal balance. This can lead to:
- Irregular cycles
- Early or delayed menstruation
- Variations in menstrual flow
- Intensified premenstrual symptoms
Most common symptoms in summer
The most frequently reported symptoms include:
- An increased sense of fatigue
- Abdominal bloating
- More intense menstrual cramps
- Greater irritability
Heat can cause vasodilation, which may in turn lead to a heavier menstrual flow. Additionally, low blood pressure and dehydration may worsen the typical feeling of exhaustion during menstruation.
Who is most sensitive to the effects of heat on the cycle?
Teenagers, perimenopausal women, and those with already irregular cycles or polycystic ovary syndrome (PCOS) tend to be more sensitive. Women suffering from dysmenorrhea (painful periods) or premenstrual syndrome (PMS) may also experience worsening symptoms during the summer months.
Practical tips for managing your period during hot months
- Stay well hydrated: drinking water helps reduce water retention and supports the body’s temperature regulation.
- Eat light and fresh: focus on fruits, vegetables, and light meals, avoiding excess salt and processed foods.
- Listen to your body: avoid pushing yourself, during your period, it’s helpful to reduce intense physical activity and opt for gentle exercises such as yoga or walking.
When to see a gynecologist
If cycle irregularities persist for more than 2 or 3 consecutive months, or if unusual symptoms occur, such as excessively heavy bleeding, severe pain, or absence of menstruation, it is always advisable to consult a specialist.
While the menstrual cycle can be affected by high temperatures, with a few precautions and careful attention to the body’s signals, it’s possible to enjoy the summer with peace of mind.
