Hello, this is Dr. Hong Myeong-hwi, Chief Physician at HyungInJae Korean Medicine Clinic Gangnam.

When summer nights stay hot, some people fall asleep later or wake up feeling unrefreshed. When sleep rhythm is disrupted, appetite, digestion, and fatigue may also change, so daily rhythm should be reviewed together.

Tropical-night sleep issues are not only about bedtime

On hot nights, the body may not cool down easily, making it harder to fall asleep. Late caffeine, late-night snacks, smartphone use, and changing air-conditioning temperatures can further disrupt sleep rhythm.

After poor sleep, appetite may change the next day, or cravings for sweet foods may increase. That is why a sleep consultation reviews not only the night environment but also daytime routines.

Air-conditioning can help, but signs of overcooling matter

Rather than avoiding air-conditioning completely, it is important to adjust temperature and timing so the body can settle before sleep. However, if the abdomen feels cold, digestion feels uncomfortable, or the body feels heavy after cooling, those responses should be reviewed.

In Korean medicine, sleep, digestion, fatigue, and body-temperature rhythm are not viewed separately. Even under the same tropical-night conditions, each person may be affected differently.

When restless nights repeat, start by organizing rhythm

Late meals, alcohol, and intense exercise can interfere with sleep. Before bed, reducing bright screens and strong stimulation while keeping a consistent wake-up time may help restore rhythm.

HyungInJae Korean Medicine Clinic Gangnam reviews sleep rhythm, appetite, digestion, fatigue, and air-conditioning habits together to guide consultation based on individual condition.
