大暑過後，點解你會頭痛、瞓唔著？中醫話你知點解 Why Does Major Heat Give You Headaches and Insomnia? TCM Explains
中文
【醫學新世代】最新一集已上架 YouTube / Spotify！今集主持人 Erica 繼續同勞惠光醫師傾大暑期間常見嘅身體警號 —— 中暑、頭痛、失眠，仲有點樣為即將到嚟嘅立秋做準備。
中暑都分兩種
陽暑：長時間喺猛烈陽光下工作或活動，體內熱氣過盛，皮膚發燙、心煩口渴，嚴重可致抽筋甚至暈厥，屬於典型急症，宜盡快求醫。
陰暑：喺酷熱天氣底下，因為狂歎冷氣、狂飲凍嘢，寒氣閉塞毛孔所致 —— 表現係頭重、周身痠痛，甚至體溫偏低但冇發燒。呢種好易俾人誤以為「唔係中暑」而耽誤調理時機，處理方法係袪寒散表，唔係清熱。
三類夏天頭痛，成因各有不同
暑熱頭痛：直曬引起，頭脹、面紅、口乾心煩，可用西瓜、冬瓜清熱袪暑。
陰暑（冷氣）頭痛：由熱入冷驟然而起，太陽穴脹痛、頸梗為主要特徵，宜袪寒散表。
肝陽上亢頭痛：頭頂或兩側脹痛，伴眼花、易怒，可用菊花、夏枯草平肝清熱。
大暑點解特別多人瞓唔著
中醫話「暑氣通於心」，夏天心火偏旺，容易心煩、失眠淺睡，呢個叫「陽不入陰」。節目分享咗一款清心潤養嘅湯水（燈心草、雪梨、百合、瘦肉），有助降溫安神；亦提到神門穴同湧泉穴，睡前輕輕按壓有助靜心助眠。
西瓜點食先啱？
西瓜有「天然白虎湯」之稱，清熱生津，但唔係人人啱食：脾胃虛寒、手腳冰凍人士唔宜多食；血壓偏低或心臟病患者、糖尿病患者宜適量；啱啱喺猛太陽底下返嚟、一身大汗嘅人，亦唔宜即刻食凍西瓜。
迎接立秋，由而家開始準備
大暑一過，好快就到立秋。勞醫師提出三個調整方向：
健脾祛濕：淮山、蓮子煲湯，清走整個夏天積落嘅濕氣。
減辛增酸：減少食辣，增加酸味食物，符合「收」嘅養生原則。
早睡早起：夏天日長夜短容易夜瞓，踏入立秋前後應該開始調整返早啲瞓、早啲起身。

The latest episode of 醫學新世代 (Medicine's New Generation) is now live on YouTube and Spotify! In this episode, host Erica continues her conversation with Dr. Arthur Lo (勞惠光醫師) about the body's warning signs during Major Heat (大暑) — heatstroke, headaches, insomnia — and how to start preparing for the coming autumn.
Not All Heatstroke Is the Same
Yang heatstroke (陽暑): caused by prolonged direct sun exposure and exertion — hot skin, restlessness, thirst, and in severe cases cramping or collapse. A true emergency pattern — seek medical help promptly.
Yin heatstroke (陰暑): brought on by excessive air conditioning and cold drinks during hot weather, trapping cold at the body's surface. Symptoms include heaviness in the head, body aches, and a lower-than-normal temperature without fever — often mistaken for "not heatstroke." The fix is dispersing cold, not clearing heat.
Three Types of Summer Headache
Heat-type headache: from direct sun — throbbing, flushed face, thirst, irritability. Eased with cooling foods like watermelon or winter melon.
Cold-type (AC) headache: from moving suddenly between heat and air conditioning — temple pain and neck stiffness are the hallmark. Treated by dispersing surface cold.
Liver-yang headache: pain at the crown or sides of the head, with dizziness and irritability. Chrysanthemum or prunella tea helps settle liver yang.
Why Sleep Gets Harder During Major Heat
In TCM, "summer heat connects to the heart" — heart-fire rises, disrupting sleep (yang failing to descend into yin). The episode shares a heart-clearing, yin-nourishing soup (rush pith, pear, lily bulb, and lean pork), along with two acupressure points — Shenmen (神門) at the inner wrist and Yongquan (湧泉) at the sole of the foot — for gentle pressure before bed to calm the spirit.
How to Eat Watermelon the Right Way
Known as a "natural white tiger soup" for its heat-clearing properties, watermelon isn't right for everyone — those with spleen-cold digestive weakness or cold extremities should limit it, those with low blood pressure, heart conditions, or diabetes should moderate portions, and it's best avoided right after intense heat exposure and heavy sweating.
Getting Ready for Autumn
Once Major Heat passes, Start of Autumn (立秋) follows quickly. Dr. Lo shares three areas to focus on:
Strengthen the spleen, clear dampness — with a Chinese yam and lotus seed soup.
Ease off spicy, lean into sour — aligning with the season's "gathering in" energy.
Earlier to bed, earlier to rise — shifting sleep and wake times earlier as days shorten.
