Enduring Trauma and Epigenetic Hope: The Urgent Call from Gaza
In Gaza, the reverberations of war reach far beyond physical destruction. They shape the very biology of its children. “I still dare to dream this genocide will end… that we can return to a normal life – as human beings,” says Mohamed Aldreini, the father of a young girl named Rewan. His plea reflects not only despair but also an enduring hope that science and humanity might still repair what war has broken.

In Gaza, the reverberations of war reach far beyond physical destruction. They shape the very biology of its children. “I still dare to dream this genocide will end… that we can return to a normal life – as human beings,” says Mohamed Aldreini, the father of a young girl named Rewan. His plea reflects not only despair but also an enduring hope that science and humanity might still repair what war has broken.
A Generation Marked by War
Rewan’s childhood, like that of countless others in Gaza, has been defined by fear, hunger, and loss. Bombardment, displacement, and medical deprivation have left visible scars—but scientists warn of invisible ones as well.
Research now reveals that prolonged trauma and deprivation can alter how genes function, through a process known as epigenetic change, which refers to how external conditions—such as stress, malnutrition, and toxins—can “switch on” or “switch off” genes without changing the DNA itself.
In children exposed to conflict, these changes can affect metabolism, immunity, and even the ability to cope with stress. They may pass from one generation to the next, perpetuating cycles of vulnerability and disease.
This means that the war’s consequences are not confined to the present moment. They could define the health and resilience of Gaza’s next generation—unless action is taken now.
The Biology of Suffering—and the Possibility of Repair
While the damage is deep, scientists stress that it is not entirely irreversible. The same biological mechanisms that record trauma can also respond to healing. As studies show, positive environmental changes—safety, good nutrition, medical care, and emotional support—can partially reverse or buffer harmful epigenetic effects.
“Lifestyle and environment play a powerful role in influencing epigenetic markers,” researchers explain. In other words, the body remembers, but it can also relearn. Stable shelter, clean water, and access to healthcare can reactivate genes that foster recovery. Psychological support, education, and play can reduce the stress hormones that silence healthy genetic functions.
In Gaza, however, these basic needs remain dangerously out of reach. Hospitals are collapsing under the weight of constant bombardment. Families are forced to flee repeatedly, and children live under the shadow of drones and starvation. Yet, amid all this, parents like Aldreini continue to dream of normalcy—proof of the extraordinary resilience that endures even in despair.
The Moral and Political Urgency
As Professor Tessa Roseboom, a developmental scientist, warned: “We need action from the international community to stop the suffering in Gaza. This conflict isn’t just about the present moment; it’s creating lifelong consequences for children like Rewan, and potentially for generations to come.”
Her words carry both scientific and moral weight. If the world fails to act, it allows trauma to become written into the biology of an entire people. If it intervenes—by ensuring access to food, medical care, education, and safety—it can still change the trajectory of millions of lives.
What is required is not merely humanitarian relief, but a reconstruction of human dignity: medical missions that prioritize children’s physical and mental health; international cooperation to rebuild schools, homes, and hospitals; and political courage to secure lasting peace. Every day of delay compounds the biological and psychological toll.
Hope as a Biological Force
As he watches his children’s health decline—and as he and his wife struggle with diabetes and high blood pressure—Aldreini still refuses to surrender hope. “I still dare to dream this genocide will end,” he says quietly. “That we can return to a normal life—as human beings.”
His words embody what scientists and humanitarian workers alike call the most powerful ingredient of recovery: hope. Hope does not erase trauma, but it provides the emotional and spiritual conditions for healing to begin. It motivates families to survive, rebuild, and nurture their children’s futures even amid ruin.
Rewan’s story, then, is not only one of tragedy—it is also a call to conscience. It reminds the world that healing Gaza’s children is not only about ending a war, but about giving them back their biological and spiritual right to grow, to thrive, and to dream.
If the world chooses silence, the wounds will be inherited. But if it chooses compassion and action, those same genes that carry the memory of war can also carry the mark of recovery. In the fragile biology of Gaza’s children lies both the cost of humanity’s failure—and the possibility of its redemption.
