Using cough suppressants can assist with which of the following?

Using cough suppressants is primarily effective in providing improved sleep quality, particularly when a persistent cough interferes with the ability to rest. Cough suppressants work by suppressing the cough reflex, which helps individuals experience fewer disruptions during sleep caused by coughing. This is especially important as restful sleep is crucial for recovery from illnesses and overall well-being.

While it is true that a cough suppressor may reduce overall cough frequency, the primary goal of using such medications, especially at night, is to enable better and uninterrupted sleep. Cough suppressants themselves do not directly address the underlying cause of cough, such as allergies or respiratory infections, which may still be present. Therefore, while the reduction of cough frequency is a potential benefit, the primary aim in the context of improving sleep is a more significant focus.

The options regarding immediate relief from allergies and providing hydration do not relate directly to the function of cough suppressants, as these remedies target different mechanisms altogether. Hydration, for instance, is typically achieved through fluid intake rather than through cough suppression, and managing allergies often involves antihistamines or other medications aimed specifically at allergic responses, rather than suppressing the cough reflex itself.
