As a female, have you ever felt that—even though the weather isn't particularly hot, once your period starts, your whole body feels like it has its own built-in heating system, and sitting for long periods leaves you feeling irritable and uncomfortable?

It’s not just you. Many women experience period overheating during their cycle, and it’s more common than we think.

The most crucial factor of overheating is hormonal fluctuations. Around the menstrual period, changes in progesterone levels affect body temperature regulation. Your basal body temperature naturally rises slightly. Increased blood circulation can also make us feel physically warmer. Besides that, sanitary pads remain in prolonged contact with the skin, restricting air circulation, which we conclude as “moisture + heat = irritation”.

That is why cooling sanitary pads appeared on the market and earned widely public attention. Its core mechanism involves stimulating the cold-sensing nerves through cooling ingredients, thereby enhancing the sensation of freshness and alleviating the irritability caused by stifling heat. Most cooling sanitary pads employ gentle menthol technology or plant-derived cooling ingredients, delivering not an icy numbness but rather the sensation of a refreshing sea breeze.

It is worth noting, however, that while it does not alleviate pain physically, it can indeed provide relief from stuffiness, particularly in certain situations such as travelling or long commutes. Those are the moments when cooling sanitary napkins feel like a small upgrade that makes a big difference.
