Answer

Yes, in many Jain upvas practices, drinking boiled water may be allowed after sunrise and before sunset, depending on the vow you have taken.

But 5 am is usually before sunrise, so traditionally you should not drink hot water at 5 am during upvas unless sunrise has already occurred at your location and your specific niyam allows it.

Explanation

In Jain Dharma, during upvas:

• Food is completely avoided.
• Boiled water may be taken only if your vow permits it.
• Water is generally taken only during daylight hours, from sunrise to sunset.
• After sunset and before sunrise, water is normally avoided.

So the key point is not simply “5 am,” but whether it is after sunrise.

Spiritual Understanding

Upvas is not only about not eating; it is a practice of self-control, awareness, and reducing attachment to the body. Following the proper time for water strengthens discipline and purity of the vow.

Takeaway

If it is before sunrise, avoid hot water. If it is after sunrise and your upvas niyam permits boiled water, you may drink it. For certainty, follow the guidance of your family tradition, guru, or local Jain sangh.
