Introduction
For individuals with relatively weak constitutions but without specific health issues such as severe respiratory diseases, joint disorders, or temperature regulation problems, using a fan appropriately during hot weather is acceptable. Fans can help lower ambient temperatures, reduce the body's heat load, and thus prevent heat-related discomfort.
People with a weak constitution but without respiratory diseases can generally use a fan. However, those with a poor constitution accompanied by respiratory conditions usually should avoid using a fan.
Individuals with a weak constitution who are otherwise relatively healthy without specific medical conditions such as severe respiratory diseases, joint disorders, or impaired temperature regulation can use a fan appropriately in hot weather. Fans can help lower ambient temperatures and reduce the body's heat load, thus preventing discomfort caused by excessive heat. In such cases, fan use typically does not cause significant adverse effects.
People with a weak constitution and existing respiratory conditions generally should not use fans. The direct flow of cool air from a fan may irritate the respiratory tract, worsen existing conditions, and intensify symptoms such as coughing and sore throat. Under these circumstances, direct exposure to air currents should be avoided, and indoor temperatures should preferably be regulated using air conditioning to minimize respiratory irritation.
Individuals with a weak constitution should maintain healthy lifestyle habits to strengthen their overall health, which can help improve their ability to adapt to environmental changes.
