I am a fitness instructor. Maybe the water temperature is too high when taking a bath, sweating too much, cerebral ischemia and hypoglycemia can all cause syncope. So pay attention to these problems when taking a bath, especially don't take a bath immediately after meals. If the brain is short of oxygen, don't move if you feel uncomfortable when hydrating before washing. Immediately lie down, rest, drink water and take a bath, which is very comfortable. Can eliminate fatigue and improve health. However, some people often feel flustered, dizzy and weak when taking a bath. You can consult me if you have any questions.
