1 to 2 hours before bedtime

The best time to take a bath is said to be 1 to 2 hours before bedtime. When a person’s core body temperature drops, it naturally induces sleepiness. After warming your body in the bath, your temperature gradually falls, which helps you fall asleep smoothly and is believed to promote higher-quality sleep. Because it also enhances relaxation, it’s recommended for people who have trouble falling asleep or who want more comfortable sleep to bathe during this time window.
