體寒是萬病之源，也是健康的頭號敵人
Cold Body Syndrome: The Root of All Illness and the Greatest Enemy of Health
生命的泉源─溫度、心跳、呼吸
The Source of Life — Temperature, Heartbeat, and Breathing
人體的構造是由各種器官所組成，稱之為有形體，和可以使各器官活動的無形能量，稱之為精神體所組成。 所謂的能量，我們的祖先稱之為“精神”，實際上精神就是精氣與神氣的合稱。故有稱其為“精氣神”或稱之“元氣”。人體要維持元氣的能量，就必須靠一種“熱能”，醫學上稱其為“體溫”。所以“體溫”是支持人類生命存在的必備條件， 雖然“體溫”是一種無形的能源，沒有它人類的軀體只不過是一具會腐爛掉的屍體而已。
The human body is composed of various organs, which together form the tangible body, and it is also driven by intangible energy, known as the spiritual body.
What we call “energy” was referred to by our ancestors as “spirit,” which is actually the combination of vital essence (jing) and spiritual energy (shen) — often termed “jing, qi, and shen” or simply “vital energy (yuan qi)”.
要有健康的身體，就要維持正常的“體溫”，並且要有正常的心跳以及順暢的呼吸。然而溫度是扮演著最為重要的角色。如果沒有正常的“體溫”，那麼心跳與呼吸也就無法維持正常狀態。
To maintain vital energy, the body relies on thermal energy, known in medical terms as body temperature.
Thus, body temperature is an essential condition for sustaining human life.
Although temperature is an intangible form of energy, without it, the human body would merely be a decaying corpse.
To achieve a healthy body, one must maintain a normal body temperature, a steady heartbeat, and smooth breathing.
Among these, temperature plays the most critical role.
Without proper body temperature, both heartbeat and breathing cannot function normally.
人體是一個熱漲冷縮的動物。當熱漲時，全身血脈，筋脈皆暢通，就不容易產生栓塞的現象；冷縮時，人體的血脈則比較容易發生栓塞的現象。體溫是身體的核心溫度(core temperature)，其形成係由攝取的食物，經由身體細胞之氧化（新陳代謝）作用後， 所釋放出來的能量，而來維繫人體的活動及生存。
The human body behaves much like a heat-sensitive system, expanding with warmth and contracting with cold.
When the body expands due to heat, blood vessels and meridians throughout the body remain open and unobstructed, making blockages less likely.
Conversely, in the cold, blood vessels constrict, making blockages more prone to occur.
Core body temperature is formed through the energy released by the oxidation (metabolism) of nutrients from food consumed, sustaining the body’s activities and survival.
平常較少運動的人及年紀較大的人，血筋脈較細，就容易產生四肢痲痺，痠痛等現象發生；尤其在夜晚（11點到早上5點）新陳代謝停頓時，人體在失溫的狀態之下，血筋脈最容易產生栓塞現象。平日有運動習慣的人，其血筋脈較粗，就較為暢通。中醫所說的“通者不痛”、“痛者不通”就是這個道理。所以我們為了身體的健康就必須有適當的運動，常保正常的體溫。
People who exercise infrequently or are older tend to have thinner blood vessels and meridians, making them more prone to numbness and pain in the limbs.
This is especially true at night (between 11 PM and 5 AM), when metabolism slows, and the body is more vulnerable to temperature loss and subsequent vascular blockages.
Those who maintain a regular exercise habit tend to have broader blood vessels and better circulation.
This corresponds with the traditional Chinese medicine saying: “Where there is flow, there is no pain; where there is pain, there is no flow.”
Therefore, to maintain good health, it is essential to engage in appropriate physical exercise and consistently preserve a normal body temperature.
