Why do you say "washing feet before going to bed is better than taking tonic"?

Washing feet is not only a traditional health habit, but also can prevent beriberi and other diseases. Washing feet with hot water can play the role of "tonic" Washing feet with hot water at 60 ~ 70℃ can stimulate peripheral nerves, regulate autonomic nervous system and endocrine system, promote blood circulation, supply more nutrients and oxygen, eliminate accumulated waste and waste gas in time, speed up metabolism, and play a role in eliminating fatigue, improving sleep and improving memory.

According to the meridian theory of traditional Chinese medicine, the five zang-fu organs of the human body have corresponding acupoints on the feet, and there are 66 acupoints on the feet, accounting for110 of the total acupoints. Often washing feet and massaging acupoints on feet can prevent and treat many local and systemic diseases. If the feet catch cold, why is it easy to cause diseases such as colds? Because people's feet are far away from the heart, their blood supply ability is poor, and their skin temperature is slightly lower, but there is a close nervous system connection between feet and upper respiratory mucosa. Cold feet can reflexively cause capillary contraction of respiratory mucosa, resulting in decreased blood flow and slow cilia movement. Therefore, the body's ability to resist germs and viruses is obviously weakened. At this time, the original bacteria lurking in the nasopharynx will take advantage of it and multiply in large numbers, making people sick. Once you catch a cold, washing your feet with hot water 2 ~ 3 times a day can promote the rapid disappearance of nasopharyngeal mucosal congestion and relieve cold symptoms.

In addition, washing feet with hot water can also eliminate fatigue and prevent lower limb pain caused by long journey or labor. Washing feet with hot water before going to bed can also regulate the function of cerebral cortex, make the cranial nerves in a relaxed and quiet state, and make people sleep peacefully. Therefore, the sentence "It is better to take tonic to wash your feet before going to bed" has certain scientific truth.
