Millions of women are spending more on period products than necessary by changing tampons and pads more frequently than recommended, according to new research from health brand Bodyform. The study found that seven out of ten women replace their period products every one to two hours, whereas experts advise changing tampons every four to eight hours and pads every three to six hours.

Bodyform’s findings suggest that many women may not be using the appropriate products for their flow, particularly those experiencing heavy periods who may underestimate their needs. The company estimates that this behavior causes users to consume up to twice the number of products necessary, resulting in an average annual cost of £52 per woman and a nationwide waste of over £500 million each year.

Dr. Monika Sharma, a general practitioner and women’s health expert collaborating with Bodyform, highlighted the knowledge gap around heavy periods. She explained that while a typical period flow resembles a steady drip, a heavy period is more akin to a tap that cannot be turned off. Dr. Sharma emphasized the importance of increasing awareness so women can better understand and manage their menstrual health.

The research also revealed that education on periods remains insufficient; 43% of the 2,000 women surveyed in April said they did not receive adequate information about menstruation during school and had to learn about it independently.

In response, Bodyform has launched the “School Of Heavy Periods” campaign in partnership with Dr. Sharma to promote awareness and provide more comprehensive education on menstrual health and appropriate product use. The initiative aims to help women better recognize their needs and reduce unnecessary expenditure on period products.
