Understanding Passive Smoking and Its Hidden Risks

Passive smoking happens when a person inhales smoke from others’ cigarettes, cigars, or hookah — even while they’re not actively smoking themselves. The air carries thousands of harmful chemicals that don’t just affect breathing but also hormone function. Onlymyhealth

Dr. Aparna Dadwal, Senior Consultant (IVF) at Yatharth Super Speciality Hospital in Greater Noida, explains that the chemicals in tobacco smoke, such as nicotine and carbon monoxide, can directly influence the menstrual cycle and reproductive hormones. Onlymyhealth

How Passive Smoking Can Affect Your Periods

According to the OnlyMyHealth article, exposure to second-hand smoke:

🔹 Contains over 7,000 chemicals that obstruct hormonal balance. Onlymyhealth
 🔹 Can lower key reproductive hormones, particularly estrogen and progesterone — hormones that regulate your cycle. Onlymyhealth
 🔹 May lead to irregular menstrual cycles, including shorter or inconsistent periods. Onlymyhealth
 🔹 Can worsen menstrual pain (dysmenorrhea) and cause restlessness. Onlymyhealth

These effects happen because tobacco toxins interfere with hormone production and balance, which are vital for a regular menstrual rhythm Best IVF Center in Greater Noida . Research beyond this article also shows that both active and passive smoking are associated with menstrual irregularity and hormone disruption.PubMed Central+1

Why Hormonal Balance Matters

Regular periods are a key sign of healthy hormonal function and reproductive health. When estrogen and progesterone are disrupted, cycles can become unpredictable — affecting ovulation and even future fertility. Scientific evidence indicates that chemicals from cigarette smoke, including those inhaled passively, can disturb hormonal pathways that regulate menstrual function. hertilityhealth.com+1

Even if a woman never smokes herself, repeated exposure to second-hand smoke — especially in enclosed or poorly ventilated spaces — may raise her risk of menstrual irregularities and longer-term reproductive issues. Best IVF Center in Greater Noida
