What Research Says About Period Syncing

Have you ever wondered if period syncing with your best friend or squad is actually a real thing? While it may seem like a special bond, researchers have found mixed results on the topic. The concept gained attention back in 1971 with the McClintock study, but subsequent research has shown conflicting evidence. Studies have shown that factors like birth control, stress, chronic illness, eating disorders, and exercise can influence your menstrual cycle more than proximity to others. So, while period syncing may sound charming, the truth is that it’s more of a myth than reality.
