Israelis suffer negative effects on health-related behavior due to Iran war - study

A recent study from the Hebrew University, as reported by The Jerusalem Post, sheds light on the profound and often overlooked health consequences of the ongoing conflict with Iran. While the physical dangers of war are apparent, this research underscores the significant toll it takes on the daily behaviors and well-being of the Israeli public.

Israelis take cover around a small, overcrowded bomb shelter in a public park as sirens sound during Iranian missile attacks on April 6, 2026 in Hod Hasharon, central Israel.

The findings are stark: a majority of Israelis have experienced a sharp decline in physical activity and sleep duration. This is coupled with a worrying increase in the consumption of ultra-processed foods, sweets, and alcohol, while intake of healthier produce has decreased. This shift in dietary habits and lifestyle, driven by the stress and disruption of war, paints a concerning picture of public health.

The Israeli public has suffered multiple negative effects on health-related behavior due to the Iran war, according to the results of a study published by the Hebrew University School of Public Policy.

Notably, the study identifies the frequency of air raid sirens as a major contributing factor to these negative health effects, directly correlating with reduced sleep and lower physical activity. This highlights the pervasive psychological impact of constant threat. The research also points out that these behavioral changes are not limited to adults; children are also affected, with increased consumption of processed foods, reduced activity, and more screen time.

“

nearly two-thirds of Israelis have experienced a "sharp decline" in overall physical activity and a reduction in sleep duration.

While international coverage often focuses on the geopolitical and military aspects of the conflict, The Jerusalem Post brings attention to these crucial domestic health implications. The study's findings serve as a critical reminder that the human cost of war extends far beyond the battlefield, impacting the fundamental health-related behaviors of the population in ways that require urgent attention and intervention.

the study found no correlation between increased consumption of ultra-processed foods and decreased consumption of produce, attributing the former to a general increase in food intake.
