To manage frequent nightfall, it is important to first understand that there is no fixed "normal" frequency for it. Occasional nightfall is generally natural, and treatment is not required in every case.
If the episodes are very frequent or are affecting your sleep, daily routine, or mental well-being, paying attention to your sleep patterns, stress levels, and overall lifestyle can be helpful. Regular exercise, adequate sleep, and stress management are also important.
Avoid taking medicines or supplements to stop nightfall without a proper assessment. If the problem persists, or if you experience weakness, pain, a burning sensation, or any other unusual symptoms alongside it, it is best to consult a doctor.
