Intensive Religious Fasting Linked To Better School Performance

The study found that students in Muslim countries demonstrated improved performance after an intensive Ramadan fasting period compared to a less intense Ramadan.

A recent study, which involved Konstanz economist Guido Schwerdt, has found that longer daily fasting periods during Ramadan have a beneficial impact on the academic performance of Muslim youth after the fasting month.

Each year, over one billion Muslims observe the fast during Ramadan, the ninth month of the Islamic calendar. Along with refraining from food and drink between sunrise and sunset, many participants increase their engagement in social activities during this time, such as breaking the fast with loved ones, friends, and the community after evening prayers.

Economists from Konstanz, Cologne, and Bern have recently concluded in a study that the social aspects of Ramadan, specifically, seem to have a beneficial effect on the academic performance of adolescent followers. The findings of the research were published in the Journal of Economic Behavior and Organization.

In the study, the researchers examine the question of whether Ramadan fasting has an effect on the school performance of eighth graders that lasts beyond the fasting period and whether this effect is related to the intensity of fasting. Their finding: Although the physically demanding fasting is known to have negative effects on concentration during the fasting period, students in Muslim countries performed better in the international school performance survey TIMSS (Trends in International Mathematics and Science Study) after intensive Ramadan fasting than after a less intensive Ramadan.

Because more intensive fasting is also associated with increased participation in religious activities such as religious services, the authors suggest that the increased school performance is due in particular to the social aspects of fasting. “Our research suggests that engaging in religious practice promotes the formation of a shared identity among school students and increases social capital that is useful for educational success. This includes, for example, contact with other young people of higher socio-economic status, support and assistance, or recognition and knowledge,” specifies Guido Schwerdt, professor in the Department of Economics at the University of Konstanz.

As the Islamic calendar and the solar calendar differ, Ramadan takes place a few days earlier each year in the solar calendar. Since the length of the day depends on the season, daily Ramadan fasting hours also vary from year to year. “This results in natural variations over the years in the intensity of fasting among believers in a given region, which we linked to school performance data collected after each Ramadan,” Schwerdt explains.

The analysis of the multi-year TIMSS data revealed in detail that increased fasting intensity is associated with better school performance in countries with a majority Muslim population. In countries where the majority are non-Muslim, there was no such effect. “Using multi-year PISA data from eight Western European countries, we were additionally able to show that adolescents with parents from countries with a Muslim majority performed better on the PISA test in years with longer daily fasting relative to other adolescents than in years with low fasting intensity,” Schwerdt adds. This effect is greater in schools with a high proportion of Muslim students than in schools with a lower proportion – another indication that the social aspects of religious activity and the formation of a common identity play a role here.
