Is it okay to take a bath, then immediately have moxibustion and go straight to sleep?
Generally speaking, whether it is safe to go to sleep immediately after bathing and moxibustion depends on the type of bath taken. It is usually acceptable to sleep after taking a warm-water bath followed by moxibustion, but it is not recommended to undergo moxibustion or go to sleep right after a cold-water bath. The detailed explanation is as follows:

If you take a warm-water bath, it cleanses the skin and promotes blood circulation. Moxibustion at this time can more effectively enhance the effect of warming and unblocking the meridians. After moxibustion, the body retains a warm sensation and pores are in a relaxed state. Drying the body promptly and keeping warm before going to sleep will not cause discomfort, and may even help relax both mind and body.
However, if you take a cold-water bath, the body's blood vessels constrict due to the cold. Performing moxibustion at this point disrupts the normal flow of qi and blood, not only reducing the effectiveness of moxibustion but also potentially allowing cold pathogens to enter the body, leading to discomfort such as dizziness, fatigue, and joint pain. Even after moxibustion, a chilled body cannot recover quickly, and sleeping immediately afterward increases the risk of adverse effects.
When performing routine moxibustion care, it is advisable to take a warm-water bath, dry the body promptly after moxibustion, and wear breathable, warm clothing to avoid catching a chill. Additionally, controlling the duration and frequency of moxibustion and adjusting according to individual constitution will help maximize its therapeutic benefits and ensure physical comfort.
