Period myths are everywhere in India — passed down through generations, embedded in religious practice, whispered at family gatherings, enforced with the best intentions and sometimes with shame. Many of these beliefs are ancient. Some were practical adaptations for their time. Most are scientifically incorrect.
This is not about disrespecting cultural tradition. It's about separating practices that cause real harm — physical restriction, psychological shame, social isolation — from the biological reality of menstruation. You can hold both: respect for your culture and a clear-eyed understanding of your body.
Myth 1: "You Are Impure During Your Period"
The Myth: Menstruating women are "unclean" or ritually impure and should not enter places of worship, touch pickles, or participate in religious ceremonies.
The Fact: Menstrual blood is not biologically impure. It is shed uterine lining and blood — the same blood that circulates in your body every day. Menstruation is a normal physiological process, not a contamination. The concept of ritual impurity during menstruation is a cultural and religious construct — not a medical or biological reality.
The World Health Organization, every mainstream medical body, and decades of scientific research are unanimous: there is nothing pathologically "dirty" about menstrual blood or the people who menstruate.
Myth 2: "Don't Exercise During Your Period"
The Myth: Exercise during menstruation is harmful, weakens the body, or makes bleeding heavier.
The Fact: The opposite is closer to true. Multiple clinical studies show that light to moderate aerobic exercise during menstruation reduces cramp intensity, improves mood (via endorphin release), and reduces fatigue. Exercise does not increase bleeding or cause harm to the uterus.
You don't need to push for personal records during your period. Rest if you feel unwell. But walking, yoga, cycling, or swimming are all not only safe but beneficial.
Myth 3: "Don't Bathe or Wash Your Hair During Your Period"
The Myth: Bathing — especially washing hair — during menstruation causes cramping, stops the flow, or is harmful to the body.
The Fact: Bathing during menstruation is completely safe and medically encouraged. Warm baths specifically are one of the most evidence-backed methods for relieving cramps — they relax uterine muscles and improve pelvic blood flow. Washing your hair does not affect your hormones, your uterus, or your menstrual flow in any way.
Good hygiene during menstruation is important for health, not harmful to it.
Myth 4: "You Can't Enter the Kitchen or Touch Food"
The Myth: Menstruating women will spoil pickles, contaminate food, or cause harm if they cook or handle food.
The Fact: There is no biological mechanism by which menstruation affects food. Pickles are preserved through salt and acid, not proximity. The temperature of your hands, your touch, your presence in a kitchen — none of these change during menstruation. This myth has been comprehensively examined and found to have no scientific basis.
Myth 5: "Period Blood Is 'Bad Blood' That Needs to Come Out"
The Myth: Menstrual blood is toxin-filled "bad blood" that the body is expelling, and a heavy period is better because it removes more impurities.
The Fact: Menstrual blood is not "bad blood." It is a combination of blood, uterine lining tissue, cervical mucus, and vaginal secretions. It is shed because the uterus is clearing its lining for the next cycle — not detoxifying the body. A very heavy period is not healthier; it can actually be a sign of a medical condition (like fibroids or hormonal imbalance) worth investigating.
Myth 6: "Irregular Periods Are Always Normal After Starting"
The Myth: Irregular cycles are normal and don't need attention, especially in teens or young women.
The Fact: Some irregularity in the first 1–2 years after the first period (menarche) is normal, as the hormonal axis is still establishing itself. But persistent irregularity after that — or irregularity that appears later in life — can indicate conditions like PCOS, thyroid dysfunction, hypothalamic amenorrhea, or other hormonal issues that benefit from early diagnosis and treatment. Irregular cycles are worth tracking and discussing with a doctor.
Myth 7: "You Shouldn't Have Sex During Your Period"
The Myth: Sex during menstruation is dangerous, painful, or medically inadvisable.
The Fact: There is no medical reason to avoid sex during menstruation for people in mutually consenting, healthy relationships. Some people find it uncomfortable; others find it relieves cramps (orgasm causes uterine contractions that can flush prostaglandins and temporarily relieve cramping). Pregnancy is still possible during menstruation, particularly for women with short cycles. STI transmission can occur during menstrual sex. Standard safe sex practices apply.
Myth 8: "Periods Should Always Be 28 Days Apart"
The Myth: Any cycle that isn't exactly 28 days is irregular or abnormal.
The Fact: The 28-day cycle is a statistical average that doesn't represent most women's reality. Normal cycle length ranges from 21 to 35 days. A woman with a consistent 32-day cycle is completely normal. What matters is that your cycle is consistent for you. Occasional variation of a few days is also normal and expected.
Myth 9: "Period Pain Is Normal — You Just Have to Bear It"
The Myth: Cramping is something every woman suffers through; it's just the price of being a woman, and complaining about it is weakness.
The Fact: Mild cramping is common. Severe, debilitating pain that prevents you from functioning is not something you should accept as normal. Dysmenorrhea (period pain) is the most common reason young women miss school and work globally, and it is treatable. NSAIDs, heat, exercise, and magnesium are evidence-based interventions. In cases of severe secondary dysmenorrhea (caused by endometriosis, fibroids, or adenomyosis), medical treatment can be highly effective.
Period pain does not have to be something you silently endure.
Myth 10: "Talking About Periods Is Shameful"
The Myth: Menstruation is a private matter that should never be discussed openly — especially not with men, not in school, and not in public.
The Fact: Silence around menstruation causes real harm. It delays diagnosis of serious conditions. It leaves young women without the information they need to manage their health. It perpetuates shame that takes years to unlearn. It prevents partners from understanding what their partners experience.
Menstruation is a normal biological function. Approximately half the world's population menstruates or has menstruated. Discussing it openly — in families, schools, workplaces, and healthcare settings — is not inappropriate. It is necessary.
Changing the Narrative
Many of the myths above were created in contexts where the biology of menstruation was not understood, where women's health was not prioritized, or where ritual restriction was used to manage social structures rather than protect women's wellbeing. Understanding their origins doesn't make them harmless.
The next time you hear one of these myths — from a family member, a colleague, or a well-meaning elder — you now have the knowledge to respond. Gently, respectfully, and accurately.
Menstruation is not a curse. It is not impurity. It is biology. And biology deserves education, not shame.
