Wear your hat strategically, too! Wear it well.

Is it better to wear a hat or not when going out? The answer depends on the situation. On days with very high levels of fine dust, it is recommended to wear a hat to minimize the scalp's exposure to the external environment. However, since wearing a tight-fitting hat for too long can hinder blood circulation in the scalp and cause waste products to accumulate, it is advised to wear a loose-fitting hat and allow for ventilation from time to time.
