Night-time dry cough can disrupt sleep, cause throat soreness, and lead to fatigue the following day. It may also indicate underlying conditions such as asthma, acid reflux, or postnasal drip. Prolonged or severe symptoms, such as coughing up blood, breathlessness, or chest pain, require immediate medical attention. Vulnerable groups, including children, the elderly, and individuals with chronic conditions, are at higher risk of complications.
