Before bathing in the hot spring, pour bathwater over yourself.
number.1 Before bathing in the hot spring, pour bathwater over yourself. Before bathing, to encourage perspiration, please stay hydrated.
Pour bathwater over yourself from your toes and fingers to ease yourself into the hot water. It is important to pour bathwater over yourself to prevent from getting dizzy by allowing the blood vessels in the skin to expand.

Furthermore, sulfur activates the pancreas, and the perspiration caused by the hyperthermic effect prevents diabetes as well. It also has anti-stress properties, and is suitable for medical treatment. However, for those with high blood pressure, we recommend a half-body bath up to the belly button.
Lukewarm (About 40°) water is ideal.
number.3 Lukewarm (About 40°) water is ideal. When they were children, there are perhaps many people who were told that they have to stay in the bathtub until they count to 100. Because of this, it is often mistakenly thought that it is better to bathe long in hot water because your body is warmed up. However, bathing for extended periods in hot water can acutely increase blood pressure and heart rate, making it dangerous. If it is lukewarm water, long baths are safe. A good indication of this is to bathe until your forehead is slightly perspiring. When you feel the perspiration, take a break by getting out of the bathtub.
You do not have to shower before getting out.
number.4 You do not have to shower before getting out. The effects of hot springs last for about 3 hours, so it is actually more effective not to rinse off before getting out.
However, because Unzen hot springs are sulfuric and strongly acidic, those with sensitive skin should rinse off with fresh water.
After bathing, take half an hour to rest.
number.5 After bathing, take half an hour to rest. After bathing, even if you feel refreshed, your body is more tired than you think. It takes about 2 to 3 hours until your blood pressure stabilizes, so take about half an hour to stay calm and be mindful of not getting chilly. Don't forget to hydrate yourself after perspiring.
Furthermore, just because you have come to a hot spring resort, doesn't mean that you should bathe excessively. In fact, excessive bathing can strain the body and cause fatigue. Keep the number of baths to about 3 a day.
