The Secrets of Bathing
Experts from the Environmental Research Institute at Nagoya University in Japan have conducted studies on changes in blood flow within the human body. Their findings reveal that only when the body is warm and sweat is produced can bathing effectively help alleviate fatigue.
Showering vs. Bathing
While taking a shower may save time, it primarily stimulates the surface of the skin without providing sufficient warmth to the internal organs. Ideally, morning showers serve as a great way to wake up both the body and mind, enabling individuals to approach work and study with renewed energy. On the other hand, soaking in a bath 1 to 2 hours before bedtime is highly recommended for optimal relaxation.
Reviving the Face During Fatigue
Many individuals experience the urge to rub their faces when feeling fatigued, often finding immediate relief. This sensation arises because the face is home to numerous expression muscles and sensitive nerves. Warm water can stimulate these nerves, while massaging the face enhances blood circulation and relaxes expression muscles. During bath time, it is advisable to rub the face at a rate of once per second, performing 3 to 5 motions each lasting no less than 3 minutes.
Optimal Water Temperature
When it comes to water temperature, **40°C** is considered ideal for relieving fatigue. The normal axillary temperature of the human body is around 37°C, while the internal body temperature typically reaches 40°C. Therefore, this temperature is closest to the body's natural heat. If the water is too hot, it can lead to excessive heat loss, resulting in discomfort rather than relaxation. Conversely, water that is too cold can cause blood vessels to constrict, making it harder to alleviate fatigue.
In conclusion, understanding the science behind bathing can greatly enhance its benefits. By choosing the right time and method, along with optimal water temperature, individuals can effectively combat fatigue and enjoy a rejuvenating experience.
