Why Should a Person Fast and Pray that Long?

Most religious doctrines prescribe a reasonable time frame for fasting and prayers. Daytime or intermittent fasting is the standard prescription among most religious scriptures. This is because the human body can be severely affected as a result of prolonged periods of food deprivation.

All our activities are empowered by the energy derived from the food we consume. Our body converts food into glucose to help us stay active during the day. However, once we stop the intake of food, lethargy sets in. The operative instinct of the human body is to rely on the stored glucose to provide some energy in order to fuel the critical internal systems.

However, after 3 days of prolonged fasting, it becomes arduous for our bodies to continue functioning. Thus, most religious orders prescribe intermittent fasting, even for prolonged periods of time like 30 days. Constant fasting and prayers would exhaust the human body resulting in starvation.

Fasting and prayers are mandated on certain auspicious religious occasions to uphold the sanctity of these events. On such days, fasts must be observed by all practicing believers of the religious order. Prolonged periods of food deprivation can incapacitate bodily functions. Dehydration and loss of consciousness may soon follow.

These short periods of fasting and prayers are good for the individual as they help him move beyond the earthly hurdles to recalibrate his bearings in accordance with the divine vision. Intermittent fasting is also considered to be biologically beneficial to the individual’s system.


Fasting and prayers are encouraged among the faithful to reconcile their souls with the spiritual realm. Most religious denominations emphasize on the need to fast to help realign the core of the individual with the scriptural doctrines.

Prayers are an indispensable part of all fasting rituals. Most religions purport that the strength of prayers is augmented during a fast. It is believed that whatever the believer asks for in the course of the fast is granted to him by God.

The act of fasting is believed to contribute to the improvement of the believer’s relationship with the Almighty. Fasting does not simply connote abstinence from food and water, but it represents a step towards mending one’s relationship with God.
