Fasting (Siyam) Is Good For Your Brain

Qur’an: Surah Al Baqara, 2: 184, “For to fast is to do good unto yourselves if you but knew it.”

Ramadan is in its third week now, and the required dawn-to-dusk fasting often feels like a daily mini–marathon. By late afternoon, hunger and thirst have sucked me dry, leaving me sleepy, slow-minded, and sometimes short-tempered.

I know that the purpose of fasting is spiritual—God will reward us in the next life—but in this lifetime, fasting sometimes makes me an ineffective, irritable person. So I was excited to learn that Harvard psychiatrist John Ratey, MD, had spoken at a recent Renaissance Weekend event about how caloric restriction can improve brain function.

I emailed Dr. Ratey to find out if those benefits might extend to religious fasting, and he sent me a 2006 paper on the brain functioning of men during the Ramadan fast. The researchers studied a small group of healthy men during and after the holy month, looking at their brain activity via functional magnetic resonance imaging (fMRI). They concluded that “all individual results showed consistent and significant increase of activity in the motor cortex during fasting.”

Other research shows similar results
That research builds on the work of other scientists, including Mark Mattson, PhD, who heads a neuroscience lab at the NIH’s National Institute on Aging. Mattson has done important research on how dietary restrictions can significantly protect the brain from degenerative diseases like Alzheimer’s or Parkinson’s. [more]

Narrated Abu Huraira:

Allah’s Apostle (s) said, “Fasting is a shield (or a screen or a shelter). So, the person observing fasting should avoid sexual relation with his wife and should not behave foolishly and impudently, and if somebody fights with him or abuses him, he should tell him twice, ‘I am fasting.” The Prophet added, “By Him in Whose Hands my soul is, the smell
coming out from the mouth of a fasting person is better in the sight of Allah than the smell of musk. (Allah says about the fasting person), ‘He has left his food, drink and desires for My sake. The fast is for Me. So I will reward (the fasting person) for it and the reward of good deeds is multiplied ten times.” (Sahih Bukhari, volume 3, number 118).
