Menstrual sanitary napkins are usually replaced every 2 hours, but it also needs to be judged according to menstrual flow and day and night time.

For women with moderate menstrual flow, sanitary napkins can be changed every 2 hours. If the menstrual flow is large, menstrual blood will soon soak a piece of sanitary towel and should be replaced at any time. If the menstrual flow is small, you can delay the time appropriately, but it is not recommended to exceed 3 hours.

Sanitary napkins can be changed frequently during the day. In order to ensure sleep at night, the replacement time can be postponed appropriately. It is recommended to choose sanitary napkins with large load at night.

Selection of sanitary napkins

1, choose individual packaging.

Usually we will look at whether the package is complete, whether there is water leakage, etc. To avoid buying fakes, we must look at the packaging and printing, sealing and film covering, whether the handwriting is clear, and whether the trademark and QR code are clear. In addition, many businesses have introduced anti-counterfeiting labels.

Try to choose small packages. The seal of each outer package and independent small package should be smooth and airtight.

2. Look for safety labels

According to the national regulations, the following signs should be marked on the outer packaging of menstrual towels: hygiene license number, production date, shelf life or validity period, implementation standard number (GB8939- 1999, GB 15979-2002), name and address of the manufacturer, etc.

3. Choose three products.

There is a hygiene license number, a date (production date, shelf life), a company name and address, etc. The manufacturer's information on the package should be as detailed as possible.
