Question
With the recent extreme heat, many people have reported symptoms of dizziness and sleepiness. What could be the cause of this phenomenon?
Answer
During hot weather, dizziness and sleepiness may be early signs of heatstroke. It is recommended to stay hydrated, choose light and easy-to-digest foods, and rest in a cool environment. If symptoms persist, it is advisable to go to the hospital for a brain Doppler ultrasound examination, as well as measurements of blood sugar and blood pressure, to rule out the possibility of insufficient brain blood supply, hypoglycemia, or low blood pressure. If accompanied by symptoms such as fatigue, chest tightness, sticky and uncomfortable stools, and decreased appetite, further medical evaluation and treatment may be necessary.
