太阳中暍证，表现为发热、恶寒，身体沉重且疼痛。脉象弦细而迟缓。小便结束后，感到怕冷、毫毛竖立。手足逆冷，稍微活动一下，身体就会发热，张口呼吸，前门牙干燥。如果误用发汗法，则恶寒加重；如果误用温针，则发热加剧；如果多次使用下法，则淋证（小便涩痛）加重。
中暍，就是中暑。暑邪也是六淫之一。邪气侵犯太阳经，就会出现寒热症状。然而，暑为阳邪，但此证反而身体沉重疼痛，脉象反而弦细而迟，虽然名为中暍，实际上兼夹了湿邪。小便结束后，感到怕冷、毫毛竖立，是因为太阳主表，内合膀胱，小便后正气暂时虚弱。手足逆冷，是因为阳气内聚而不能外达，所以稍微劳作，气机外泄而身体发热。张口呼吸、前门牙干燥，是因为热盛于内，而气散于外。大概暑虽然是阳邪，但气机常与湿邪相合，这是阳寻求阴的道理。暑因湿而入，暑反居于湿之中，这是阴包裹阳的现象。治疗时，完全像分解风湿的方法一样，用辛味药来发散湿邪，用寒凉药来清解暑热就可以了。如果发汗，只会徒然损伤体表；用温针，则会更加助长热势；用下法，则热邪会内陷，变证随之产生，这些都不是治疗暑湿的正治之法。
太阳中热证，就是喝病（疰夏）。表现为汗出、恶寒，身体发热且口渴。
中热，也就是中暑。“喝”是暑气的意思。恶寒，是因为热气侵入导致皮肤松弛，腠理开泄，开泄则感觉洒洒然怕冷，这与伤寒的恶寒不同。出汗、发热且口渴，说明表里热势炽盛，胃阴即将枯竭，向水求救，这是中暑而不兼湿邪的证候。
太阳中湿证，表现为身体发热、疼痛沉重，脉象微弱。这是因为夏季受冷水伤害，水气行于皮中所致。
暑邪中人，阴虚而多火的人，暑邪就寓居在火中，表现为汗出、烦渴；阳虚而多湿的人，暑邪就潜伏在湿内，表现为身体发热、疼痛沉重。所以暑病常常以湿邪致病，治疗湿邪就是治疗暑邪。因此，《金匮要略》用一味瓜蒂散，去除身面四肢的水气，水去则暑邪无所依附，将不治疗而自然解除。这是中暑兼夹湿邪的证候。
Taiyang Zhongyue (Heatstroke affecting the Taiyang channel) presents with fever, aversion to cold, heaviness of the body, and pain. The pulse is wiry, thin, and slow. After urination, there is a sensation of chilliness and piloerection. The hands and feet are cold. Upon slight exertion, the body becomes hot; the mouth opens, and the anterior teeth are dry. If sweating methods are applied, aversion to cold will worsen; if warm needle therapy is used, fever will intensify; if purgation is frequently employed, strangury (dysuria) will become severe.
Zhongyue refers to heatstroke. Summer-heat is one of the Six Evils. When it affects the Taiyang channel, it manifests as alternating chills and fever. However, summer-heat is a Yang pathogen, yet this syndrome presents with body heaviness and pain, and the pulse is wiry, thin, and slow. Although named Zhongyue, it actually involves dampness. The chilliness and piloerection after urination occur because Taiyang governs the exterior and internally connects with the Bladder; urination temporarily depletes Qi. Cold hands and feet result from Yang Qi gathering internally and failing to reach the extremities; thus, slight exertion causes Qi to escape and the body to heat up. Opening the mouth and dry anterior teeth indicate excessive heat within and dissipating Qi on the outside. Generally, although summer-heat is a Yang pathogen, its Qi often combines with Dampness, reflecting the principle of Yang seeking Yin. Summer-heat enters via Dampness, and summer-heat resides within Dampness, reflecting the image of Yin enveloping Yang. Treatment should follow the method for resolving Wind-Damp: use Acrid substances to disperse Dampness and Cold substances to clear Summer-heat. Sweating merely damages the exterior; warm needles exacerbate heat; purgation causes heat to sink inward, leading to various complications. None of these are correct treatments for Summer-heat-Dampness.
Taiyang Zhongre (Summer-heat Heat in Taiyang) is known as He disease (Zhu Xia). It presents with sweating, aversion to cold, body heat, and thirst.
Zhongre is also heatstroke. "He" refers to the Qi of summer-heat. Aversion to cold occurs because heat entering relaxes the skin and opens the Cou-li (pores); when open, one feels chilly (Sasara), which differs from the aversion to cold in Cold Damage. Sweating, fever, and thirst indicate blazing heat in both the interior and exterior, with Stomach Yin nearing exhaustion, seeking relief from water. This is the syndrome of heatstroke without Dampness.
Taiyang Zhongshi (Dampness in Taiyang) presents with body heat, painful heaviness, and a faint pulse. This is caused by injury from cold water in summer, where water Qi circulates in the skin.
When Summer-heat invades the person, those with Yin deficiency and excess Fire harbor Summer-heat within Fire, manifesting as sweating, vexation, and thirst. Those with Yang deficiency and excess Dampness harbor Summer-heat within Dampness, manifesting as body heat and painful heaviness. Therefore, Summer-heat diseases often involve Dampness, and treating Dampness is equivalent to treating Summer-heat. Thus, *Jin Gui Yao Lue* uses a single herb formula of Geng Ti (Cucumis Trichosanthis Fruit) to remove water from the body, face, and limbs. Once the water is removed, Summer-heat has no basis and resolves spontaneously. This is the syndrome of heatstroke complicated by Dampness.
