Pocari Sweat Occasions

When you sleep/wake up

It’s worth noting that people lose a significant amount of water from sweating and exhaling even when they are asleep. According to data from the Otsuka Pharmaceutical Saga Nutraceuticals Research Institute in 2000, this amount is about 500ml over eight hours at approximately 29°C.

In the past, people used to place water by their pillows and drink it before bed to replenish the water lost during sleep. This practice was called “Hosui,” and it was believed to have a positive effect on health.

Nowadays, drinking Pocari Sweat before going to bed not only helps replenish water but also ions (electrolytes), which is a modern approach to the old practice of Hosui.

Since it is not possible to rehydrate for approximately eight hours during sleep, your body may feel quite thirsty when you wake up. Incorporating Pocari Sweat into your morning routine can quickly replenish lost water and promote a healthy start to the day.

However, it’s important to remember that drinking before bed may increase the risk of tooth decay. Therefore, we recommend gargling or brushing your teeth after drinking Pocari Sweat before going to bed to prevent cavities.
