Fasting is one of the most important rituals of Islam, and Muslims are required to fast during Ramadan, the ninth month of the Islamic calendar.

“O you who have faith! Prescribed for you is fasting as it was prescribed for those who were before you, so that you may be God wary” (2:183).

Now, as Ramadan is around the corner and the novel Coronavirus is continuing to spread globally, many Muslims worldwide are wondering if fasting could pose a higher risk of catching the COVID-19 virus, due to dehydration. They may raise some more questions, as is it safe to fast during this global pandemic? Doesn’t it weaken our immune system? And some wonder if they could be exempted from fasting to prevent catching this disease and remain healthy.

Let’s have a look at this question -to fast or not to fast? - from two different aspects: Science-based and religion-based. 

Does Dehydration Make us More Prone to Catching Coronavirus?

According to the WHO and health experts’ recommendations, people are advised to drink plenty of water to prevent dehydration and stay healthy. Still, it will not prevent anyone from catching the new Coronavirus.

“Dr. William Schaffner, an infectious-diseases expert at Vanderbilt University, said the claims are incorrect. While medical professionals typically recommend keeping up fluid intake, Schaffner said drinking more water will not keep anyone from catching the virus. “We always caution anyone healthy and people who are sick to keep up the fluid intake and keep mucus membranes moist,” he said. “It makes you feel better; there is no clear indication that it directly protects you against complications.” [1]

Does Fasting Weaken our Immune System?

No, in fact, many scientific studies have shown the wide-ranging health benefits of intermittent fasting in boosting our immune system and living a longer life. The New England Journal of Medicine has recently published a review of research on the beneficial effects of intermittent fasting on health, aging, and disease:

“Evidence is accumulating that eating in a 6-hour period and fasting for 18 hours can trigger a metabolic switch from glucose-based to ketone-based energy, with increased stress resistance, increased longevity, and a decreased incidence of diseases, including cancer and obesity.” [2] 

Even more interestingly, although some study claims that prolonged water fasting could have a slightly detrimental effect on the immune system, it also shows that immunity returns to a better state soon after eating and drinking again. [3]

What Do Islamic Jurists Say about Fasting during this Pandemic?

First of all, the obligation of fasting during the holy month of Ramadan is an individual duty, and anyone who has the conditions to do so must fast, regardless of whether it is obligatory for others or not. According to Ayatollah Sayyid Ali Sistani, one of the well-known Islamic jurists, if a Muslim fears that he/she will catch Coronavirus, even if he/she takes all precautionary measures, he/she will be relieved of the obligation for each day he/she remains in fear of catching the disease – if he/she were to fast. However, if he/she can reduce the probability of catching the disease so that it becomes reasonably insignificant – even by staying at home and not mixing closely with others, using a mask, medical gloves, frequent disinfection and so on – such that it does not cause unbearable difficulties for the individual, his/her obligation to fast is not waived. [4]

Another Islamic jurist follows the same line and adds that if a doctor forbids someone from fasting, due to the high risk of getting this virus, that person is not allowed to fast. But this should not lead to disrespecting others that fast and eating in public [5]. Many other Islamic jurists also confirm the fact that one should decide if fasting is risky for him/her or not. If “an individual has a reason to believe that fasting will cause illness, intensify or prolong an illness, or delay one’s recuperation,” he/she is not obliged to fast. But he/she should make up for the missed fastings later in the year [6].  However, some other Islamic jurists consider fasting an obligatory practice whose obligation is not lifted in this period, except if one thinks there is a high probability of getting the disease by fasting [7].   

After all, it is essential to note that fasting in Islam is expected of those who are healthy enough to do so: “Allah desires ease for you, and He does not desire hardship for you” (2:185)

 And sick people who fear that fasting may make them worse, risk their health or slow down their recovery are permitted not to fast:
“But should any of you be sick or on a journey, let it be a [similar] number of other days. Those who find it straining shall be liable to atonement by feeding a needy person” (2:184).

In conclusion, regarding the feedback received from the World Health Organization, fasting has nothing to do with the possibility of an increased risk of catching coronavirus. On the other hand, it is not easy to say for sure whether fasting offers some level of protection and immunity against the COVID-19 virus during this global crisis, so we’d better stick to the things we know would work: social distancing, avoiding gatherings, performing rituals separately, hand-washing, hygiene, and self-isolation.

When it comes to fasting, many questions might come to mind. Is it even healthy? Is it safe? Does it benefit my fitness goals? Those are the very most typical questions that are asked by the public about fasting. The purest form of fasting, as I am sure you have heard of it, is that of intermittent fasting (IF). Which happens to be good for your health, apt to your fitness goals, and safe. 

Intermittent fasting is one of the most popular health and fitness trends nowadays, except that it `is´ not, but `has been´ for thousands of years, practiced by different societies and cultures for a wide range of variable causes. Whether a Zen monk, yogi, Tibetan monk about the Himalayas, or a participant of any Abrahamic or dharmic faith, they all have one thing in common; and that is that they all have fasted. [1]  As mentioned in the Holy Quran, “O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous(2:183) and as Imam Baqir (AS) has said “Islam has five pillars, and those are: the Prayers (Salat), the alms-tax (Zakat), the holy Pilgrimage (Haj), fasting (of Ramadhan) (Sawm), and the leadership (Imamate),” further centering on the importance of Fasting [2]. Moreover, as the Prophet (PBUH&HP) bids, “All that it is due of Zakat, and Fasting is that of the body´s” [3]. 

Fasting in Islam is a symbol of freeing oneself from false earthly desires to a more grandiose world, in which possibilities are limitless and power is infinite. In fact, we are too driven by day-to-day life that we never contemplate the things that matter anymore, or at the very least, we do not get to do so. Imam Sadiq (AS) has bid, “Allah has manifested fasting as an obligation to bring equality between the poor and the rich” [4]. 

The Power of the Present Moment

Such spiritual undertakings such as fasting and praying have a single most important thing in common, and that is the essence of the present moment. The more engaged one is with the high vibrational energies of the moment, the less compulsive and unconscious one becomes. Now we can say that acts like prayers (which brings awareness and facilitates brain and heart coherence) and meditations separate us a little bit from the compulsive and sub-conscience-driven life style of the modern society.     
But, imagine you were introduced to a life style of letting go of compulsive behaviours, thoughts, and actions; and deeply become more integrated into the present moment in which high vibrational energies reside. Ramadhan provides this opportunity for over a billion Muslims and the people of other faiths who fast because of the fun it brings, and all fasting acts for that matter. It is very important to know that we are being so driven by life that we don’t know what fun is anymore. We are so reactive nowadays, that we are no more proactive towards our lives, being triggered left and right by what the scholars call super-stimuli (over-stimulating aspects of the modern society, which our cave-man brains have not adapted to its bursts evolutionary-wise) , which our ancestors did not dispose of until as late as late twentieth century. With the rise of super-stimuli, and the further adaptation, but not evolution, of the human brain to the dopamine (the motivation, and reward neurotransmitter) hits, we live a life of chasing phantoms(reliefs) and not challenges. 

Dopamine Detoxification 

One of the hot topics of modern productivity is the deactivation of the brain´s reward centre for a period of time. Our brain´s reward centre has become very reactive, and non-proactive, and keeps on rewarding us a little shot of dopamine, whether craving a cigarette, a glass of wine, a cup of coffee, or even as far as watching pornography and binge eating for several hours. Activities which have been proven to deliberately deteriorate our physical state [5]. Yet, our brain´s reward centre keeps hitting us with feel-good chemicals. This process goes on and on as far as lowly losing the initial sensation to the initial amount, bringing up the threshold, hence; the excessive habit loop. During Ramadan, though, we break the bad old habits, we become new, as whole as a little baby, as though we have had our serotonin (wellness neurotransmitters) re-set button pushed. Fasting is not only about freeing oneself from food, but rather from all other super-stimuli, such as; negativity, excessive sexual activities, and spilling stimulating liquids down our throats all day long. 

Now, we are freed of compulsive unconscious behaviours, and embrace the true happiness of life, the state of blissfulness and joy which is what we are born with. We can sit down not eating, not drinking, not engaging in highly stimulating activities and still feel joy, and a continuous state of happiness, what had since long been robbed of us by the advancements of the modern society. We can feel great now, with the strongest paradigm of manifestation, as mentioned by David R. Hawkins, the one and only superior paradigm to all others: being. [7]  Not having, not doing, but simply letting go of the earthly, and connect to the great source of all consciousness that is “God”. As Imam Ali (AS) said “Fasting is as much staying aloof of the taboos as it is staying away of eating” [6]. 

Physical Health Benefits of Fasting

Studies have shown that the time restricted feeding (TRF) or intermittent fasting (IMF) leads to more weight loss, which is clearly manifested in the Islamic approach to fasting. Consuming more calories in the morning has shown to be more effective than that of evening, as far as metabolism, weight loss, and prevention of obesity-which has come to be a major epidemic in the developing nations. There are self-reports of significant decrease in the volume of the fat tissues under skin which distort the good looks of our bodies. Referred experiments prove that the TRF significantly decreases the body fat, but does not affect the weight in short period of 15 days. Although more weight loss upon hitting a 30 days threshold is expected. [8]

Although cutting calories from everyday diet has quite similar effects like the IMF, Small reductions in total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, triglycerides, and fasting glucose and insulin with IMF have been reported in several studies. The greatest decrease of which is in bad cholesterol contributing to a lesser chance of suffering from heart diseases.

Conclusion
Health benefits of fasting encompasses far greater areas than that of the physical health. It mentally alleviates the individual, and activates a new set of  body-substances , which grants us to focus on long-term goals and areas of our lives, and become more process-oriented than result-oriented, and adapts our brain´s reward centre to long-term rewards rather than short-term pleasures. Fasting is very complex, common people have been observed achieve the uncommon by long-term fasting; in fact, so complex that by all advancements in medical science, delving deeper into the topic is an area of future investigations.
