What is the significance of bathing early in the morning during Kartik month?

Kartik Snan, the practice of bathing daily before sunrise (during Brahma Muhurta) usually in a sacred river such as Ganga or Yamuna followed by worshipping Lord Vishnu, is observed during Kartik month. It is believed to wash away sins, while Ayurveda says it helps generate internal energy. This practice is considered a symbol of spiritual purity, discipline and devotion.
