Chushu: Doctors Reveal Key Time for Gut and Fatigue Recovery

As the traditional Chinese solar term Chushu arrives, marking the end of summer's intense heat, the body enters a critical period of recovery and repair. Physicians emphasize that this phase, rather than a point of full restoration, is when the body's healing mechanisms truly begin to function effectively.

Chushu is not the end point of physical recovery, but the time when repair truly begins to operate effectively, and the key stage for the body and intestines to gradually regain their rhythm.

During Chushu, the body's internal rhythm gradually re-establishes itself. After the initial recovery phase following the peak of summer, the parasympathetic nervous system becomes more active. This allows the body to catch up on repair and regulation, leading to a more consistent daily rhythm. While not necessarily feeling stronger, individuals may notice a shift towards stability, with fatigue no longer accumulating relentlessly and the body having a chance to process exhaustion.

The gut also shows noticeable improvements during this time. Following the repair initiated after the summer's end, the gut's microbiome and digestive rhythm begin to stabilize. Sensitivity and irregularity experienced in late summer gradually decrease, leading to more regular bowel movements and consistent responses to food. The gut barrier and immune regulation functions also start to mend, reducing overreactions to external stimuli. However, this does not signify complete recovery, but rather the system's re-establishment of its operational mode.

After Lìqiū, the body has already shifted from high output to internal repair. By Chushu, the parasympathetic nervous system function gradually increases, allowing repair and regulation to catch up with previous consumption, and the overall rhythm becomes more consistent.

Emotional well-being also sees a positive shift. As the nervous system disengages from high-load states and its regulatory capacity recovers, emotions become less persistent. While fatigue and stress may still be present, they become more manageable and less likely to become stuck. The overall state transitions from being passively affected to having the capacity to recover and find an outlet.

In terms of the intestines, changes during Chushu are usually more noticeable. After the repair initiated by Lìqiū, the gut flora and digestive rhythm begin to gradually stabilize.

Physicians warn that Chushu is often overlooked as a vital recovery stage. Because discomfort lessens, many assume full recovery has occurred. However, the body's systems are still rebuilding. Increasing physical demands too early can disrupt these ongoing repairs, leading to a cycle of instability, recurring fatigue, or digestive problems after a brief period of improvement.

When the nervous system gradually withdraws from high load and regulatory capacity recovers, emotions no longer get stuck.
