As the summer sun reaches its peak, we naturally feel a shift—not only in our environment but in our bodies, energy levels, and emotions. According to Traditional Chinese Medicine (TCM), each season corresponds with specific organs and energetic patterns. In summer, the heart and small intestine take center stage.
At Integrative Acupuncture, we love helping our patients stay in harmony with the seasons using acupuncture, herbal medicine, and lifestyle guidance rooted in TCM. In this post, we’ll explore how the heart and small intestine function within the TCM framework and share ways you can support your health during the vibrant summer months.
Summer in the Five Element Theory
In TCM, the Five Element Theory — Wood, Fire, Earth, Metal, and Water — helps us understand the relationships between nature, our bodies, and the changing seasons. Summer is associated with the Fire element, and its related organs are the Heart (Yin) and Small Intestine (Yang).
The Fire element is also connected to joy, expansion, light, and transformation. Think of the way nature blooms outwardly during this season — that same expansive energy moves through our bodies, too. But as with all elements, balance is key.
The Heart in TCM: More Than Just a Pump
In Western medicine, the heart is primarily seen as the organ that pumps blood throughout the body. In TCM, it plays a broader role. The Heart is the “Emperor” of the organ systems, responsible for:
- Governing blood and circulating it through the vessels
- Housing the Shen, or spirit, which encompasses mental clarity, emotional balance, and consciousness
- Regulating sleep, memory, and speech
When the Heart is in balance, we feel calm, joyful, and mentally clear. When it’s out of balance, symptoms like anxiety, insomnia, palpitations, or even restlessness may appear.

The Small Intestine: Sorting the Pure from the Impure
In TCM, the Small Intestine is more than a digestive organ. Its key role is discrimination — separating the “pure” from the “impure.” Physically, this means absorbing essential nutrients and eliminating waste. Energetically and emotionally, this organ helps us discern truth, make clear decisions, and digest life experiences.
When the Small Intestine is functioning well, we can absorb what nourishes us — both physically and emotionally — and let go of what doesn’t serve us. If it’s out of balance, we might experience poor digestion, confusion, or difficulty making decisions.
Common Heart and Small Intestine Imbalances in Summer
Because summer naturally amplifies the Fire element, it’s easy for it to become excessive — leading to symptoms of heat or overstimulation. Here are a few common issues we see during this season:
1. Insomnia or Restless Sleep
Too much Heart Fire can disturb the Shen, leading to trouble falling or staying asleep.
2. Anxiety or Feeling Overwhelmed
An imbalance in the Heart can manifest as racing thoughts, irritability, or feeling emotionally “scattered.”
3. Digestive Troubles
Excess heat can affect the Small Intestine, resulting in bloating, gas, or loose stools.
4. Mouth Sores or Thirst
These are signs of internal heat, often linked to the Heart and Small Intestine channels.
Supporting Your Heart and Small Intestine During Summer
The beauty of TCM is its focus on prevention and seasonal alignment. Here are a few simple ways to nourish your Fire element this summer:
1. Eat Cooling, Hydrating Foods
Favor foods that are light, fresh, and slightly cooling in nature. Think watermelon, cucumber, mint, leafy greens, and bitter vegetables like dandelion greens or romaine lettuce. Avoid overly spicy or greasy foods that can aggravate internal heat. Tip: Bitter flavors support the Heart and help clear heat.
2. Stay Hydrated
It sounds basic, but proper hydration is essential. Dehydration can overwork the Heart and cause fatigue or dizziness. According to the Mayo Clinic, most adults should aim for around 11.5–15.5 cups of fluids per day, depending on activity level and climate.
3. Practice Mindful Rest
While summer brings longer days and more activity, it’s important to balance that outward energy with rest and mindfulness. Short afternoon naps, quiet evenings, or gentle breathing exercises help calm the Shen.
4. Schedule Seasonal Acupuncture
Acupuncture is a powerful tool to balance the Fire element and harmonize Heart and Small Intestine function. Whether you’re experiencing anxiety, insomnia, or digestive issues — or just want to stay balanced — now is the perfect time to check in.
What Does Modern Research Say?
While Traditional Chinese Medicine approaches health from a different lens than Western biomedicine, there is increasing scientific interest in its practices. For example:
- A 2022 systematic review published in Frontiers in Psychiatry found that acupuncture may be a helpful complementary therapy for anxiety and insomnia, conditions often related to Heart imbalances in TCM. Source
- Studies suggest that acupuncture can modulate the autonomic nervous system and reduce markers of stress, helping restore parasympathetic (“rest and digest”) function. This supports TCM’s view of harmonizing Heart and Small Intestine energy. NIH Overview
In Harmony with the Season
TCM teaches us that good health isn’t just about avoiding illness — it’s about living in alignment with the rhythms of nature. When we honor the season of Fire and nurture the Heart and Small Intestine, we create space for joy, clarity, and inner peace.
Whether you’re new to acupuncture or a returning patient, we’re here to help you stay balanced this summer. Come in for a seasonal tune-up, or simply follow the tips above to keep your fire bright — but not overwhelming.
