Hello, this is Sunyujae Korean Medicine Clinic, where kind hearts reside.


“Doctor, why do I feel so drained these days? I wake up tired, and my appetite has completely disappeared.” This is a common complaint we hear in the clinic recently. Not only seniors but also office workers in their 30s and 40s, and even teenagers, often visit with similar symptoms. It’s easy to dismiss these symptoms as simple ‘summer fatigue,’ but in Korean medicine, we approach this as ‘Juha-byeong (注夏病).’
Especially during times like these, with recurring heatwaves and tropical nights making it difficult to get enough rest, physical exhaustion and weakened digestive function can combine, causing the entire body to tire easily and recover slowly. Today, we will discuss Juha-byeong (注夏病), which frequently appears during such hot seasons. Juha-byeong – 注夏病 Suji-gu Sunyujae Korean Medicine Clinic – Juha-byeong: Summer Symptoms of Unexplained Fatigue and Lethargy Due to continuous summer heat and high humidity,
the body’s Jinyeok (津液, body fluids) are depleted, energy (氣力, Qi) is diminished, and gastrointestinal function weakens – these are the seasonal debility symptoms of Juha-byeong (暑夏病). In Korean medicine, it is believed to occur due to the influence of ‘Eumheo (陰虛, Yin deficiency),’ ‘Won-gi bujok (元氣不足, deficiency of original Qi),’ and ‘Seopyeol (濕熱, damp-heat).’ “Juha-byeong is not just ‘summer fatigue.’
When energy drains and body fluids dry up, it can lead to chronic fatigue that is not easily recovered. Do not take it lightly; if symptoms persist, it is advisable to seek a prescription tailored to your constitution and condition at a nearby Korean medicine clinic.” Korean Medicine Classification of Juha-byeong Sunyujae Korean Medicine Clinic In Korean medicine, Juha-byeong is broadly classified into ‘Biwiheoyak-hyeong (Spleen-Stomach Deficiency Type)’ and ‘Seoyeol-hyeong (暑熱型) (Summer-Heat Type)’ based on constitution and symptom patterns.
Biwiheoyak-hyeong Juha-byeong Suji-gu Sunyujae Korean Medicine Clinic Biwiheoyak-hyeong Juha-byeong primarily occurs in individuals with a weak digestive system. Symptoms include decreased appetite, watery diarrhea, weight loss, and weakness in the limbs. As the Spleen and Stomach’s transportation and transformation functions decline, food digestion and qi transformation do not occur properly, leading to both energy depletion and nutritional imbalance.
In such cases, prescriptions that protect the Spleen and Stomach and replenish qi are central to treatment. Seoyeol-hyeong Juha-byeong Sunyujae Korean Medicine Clinic On the other hand, Seoyeol-hyeong Juha-byeong mainly appears in individuals with excessive internal heat or those who sweat excessively. Prominent heat-related reactions include dry mouth, severe thirst, increased body heat, flushed face, and easy irritability.
This is due to external heat and internal Seopyeol (濕熱, damp-heat) acting together, resulting in the depletion of body fluids and an increase in body temperature. Treatment focuses on reducing heat and replenishing body fluids. Symptoms like feeling drained, dry body fluids, and weakened digestion amidst continuous heat – it’s easy to just think, ‘Oh, it’s just hot and I’m tired,’ isn’t it?
However, in Korean medicine, this state is diagnosed not as simple heatstroke but as ‘Juha-byeong (注夏病),’ a condition of bodily debility, and treated to restore physical strength and digestive power. At Sunyujae Korean Medicine Clinic, we offer customized herbal medicine and lifestyle management tips to improve summer debility, including Saengmaeksan Plus, which helps replenish energy and restore body fluids.
