Two-Thirds of Israelis Report Health Drop During Latest Conflict

A new study by researchers at the Hebrew University has found that the war between Israel and Iran has led to widespread declines in physical and behavioral health among Israelis.

The research, which has not yet undergone peer review, was led by epidemiologist and clinical dietitian Dr. Roni Lotan and Prof. Eyal Pe’er. It found that nearly two-thirds of respondents reported a sharp drop in physical activity, alongside reduced sleep duration.

The study also identified a shift in eating habits, with just over half of participants reporting increased consumption of ultra-processed foods such as sweets and pastries. At the same time, many reported eating fewer fruits and vegetables, while alcohol consumption also rose.

Researchers noted that the increase in processed food intake did not directly correlate with the decrease in produce consumption, suggesting an overall rise in food intake rather than a simple substitution.

The impact appeared to be more pronounced among women, according to the findings.

A link was also found between reduced physical activity, sleep disruption, and increased consumption of ultra-processed foods, indicating that these changes often occurred together rather than in isolation.

Among smokers, the study observed an increase in daily cigarette use, though researchers cautioned that the sample size for this group was limited.

One of the key factors associated with these changes was the frequency of air raid sirens, which was linked to both poorer sleep and reduced activity levels.

The effects were also evident among children. Around half of parents surveyed reported that their children were eating more ultra-processed foods and sleeping less, while 85 percent said screen time had increased for children aged two to ten.

Researchers said these changes tended to cluster, pointing to a broader deterioration in children’s health behaviors during the conflict.

The study also found that parents of young children were less likely to increase alcohol consumption, suggesting that childcare responsibilities may have acted as a moderating factor.

The authors said the findings highlight the need for targeted public health interventions during periods of conflict, including support for maintaining physical activity, healthy eating habits, and structured daily routines.
