Man Explains How Many Tampons Women Need Annually And Is Completely Wrong

In addition to that, as Insider points out, a tampon should be changed every four to eight hours to avoid the potentially dangerous risk of infections developing or instances of Toxic Shock Syndrome (TSS). In fact, Katharine O'Connell White, MD, MPH, director, Fellowship in Family Planning, Department of OB-GYN at Boston University, Boston Medical Center, suggests that the recommendation of eight hours is actually pushing it regarding vaginal health. She suggests women wear a pad overnight to avoid potential risks.

So, using that guideline, and the assumption that the average period length is five days, a woman should change her tampon no less than 15 times per monthly cycle, based on waiting eight hours between changes. Already, this is more than double what was recommended by the man in his post.

As to be expected, many women commented on the Twitter post of his calculations.

"Does he think that a period goes on a holiday?" One Twitter user wrote.

"Like it's getting to Christmas, time for a trip to Mexico. Like it's an employee."

Others also pointed out the dangers of leaving tampons in for long periods of time.

"Do you want TSS? Because that's how you get TSS."
