The method of coffee bath is also very simple. You can first boil coffee beans into espresso (stronger than usual) and pour them into a hot pool of 38 degrees for soaking. If you think it's a waste of coffee beans, you can also pour the remaining coffee grounds directly into hot water. When taking a bath, the soaking height is best to bathe the lower body in the heart. The soaking time is about 15 ~ 20 minutes. If you have cardiovascular disease, please take an intermittent bath; You can choose the soaking time according to your own situation, such as soaking for 5 minutes, getting up and resting for 3 minutes, and then soaking in the pool for 3 times continuously. The immersion height can also be above the heart.
