How climate disasters hurt adolescents’ mental health

Young people traumatized by Hurricane Maria were more likely to report substance use.

After a hurricane, flood, wildfire, or other disaster strikes, a great tallying commences: the number of people injured and killed; buildings damaged and destroyed; acres of land burned, inundated, or contaminated. Every death is recorded, every insured home assessed, the damage to every road and bridge calculated in dollars lost. When the emergency recedes, the insurance companies settle their claims, and the federal government doles out its grants, communities are expected to rebuild. But the accounting misses a crucial piece of the aftermath: Worsening disasters are leaving invisible mental health crises in their wake. 

A handful of studies have sought to quantify the scope and scale of the mental health consequences of disasters that have occurred in the recent past, such as 1992’s Hurricane Andrew, 2005’s Hurricane Katrina, and 2017’s Hurricane Irma. The results point to an alarming trend: The stress and trauma of losing a loved one, seeing a home destroyed, or watching a beloved community splinter has resounding mental health repercussions that stretch on for months, even years, after the disaster makes its first impact. Anxiety, depression, sleep disorders, post-traumatic stress, and sometimes suicidal ideation and suicide follow disasters. 

Children and adolescents — who are still learning to regulate their emotions, rely on routine and a sense of safety more than most adults do, and get social and mental stimulation from interacting with peers — are among the demographics most vulnerable to the chaos and isolation brought on by extreme weather events. 

A study published in mid-January in the Journal of Traumatic Stress analyzed survey data from more than 90,000 public school students across Puerto Rico in the months following Hurricane Maria’s landfall in September 2017. Maria, a Category 5 storm that caused widespread destruction in the northern Caribbean, killed nearly 3,000 people in Puerto Rico and caused mass blackouts that left huge portions of the island without electricity and drinking water for months — a reflection of decades of disinvestment in and mismanagement of the island’s infrastructure.

Some 30 percent of the students surveyed five to nine months after the hurricane made landfall said they felt their lives were threatened by the storm, 46 percent said their homes were significantly damaged, and 17 percent said they were injured or a family member was injured.

Roughly 7 percent of the young people surveyed — about 6,300 students — developed symptoms of post-traumatic stress disorder, or PTSD, after the storm. For this subset, the psychological consequences of living through Maria and its aftermath were extreme. 

Prior research has shown that young people are more likely to turn to alcohol as a coping mechanism after experiencing traumatic stress, a precursor to PTSD. A study published in 2021 hypothesized that children living in Louisiana who were exposed to Hurricane Katrina in 2005 and the Deepwater Horizon oil spill in 2010 would have higher rates of anxiety, depression, and alcohol use as teenagers than the general population in southeastern Louisiana. The researchers found a connection: the more severe the traumatic stress during and after the disaster, the more likely the individual was to report substance use. 

“There is an initial link that has been found in other research,” said Alejandro L. Vázquez, the lead author of the Puerto Rico study and an assistant professor of psychology at the University of Tennessee, Knoxville. But a huge question remains. “The mechanism for why kids are using substances in this situation is less clear,” he said. Vázquez wanted to figure out which specific symptoms of traumatic stress were linked to alcohol and substance abuse in the students who suffered PTSD symptoms after Hurricane Maria. He found that angry outbursts and irritable behavior, two of the core symptoms of PTSD, were strongly correlated to self-reported substance use. 

Robbie Parks, an environmental epidemiologist at Columbia University’s Mailman School of Public Health, called the study a “fantastic synthesis of how the hidden burden of climate-related disasters such as Hurricane Maria can have long-lasting, non-obvious impacts on the way that our health and well-being is maintained.” Parks was not involved in the research.

The ultimate purpose of the research, Vázquez told Grist, is to arm counselors, teachers, and mental health professionals with information that can help them identify PTSD as it forms in young people post-disaster and intervene before it prompts them to develop unhealthy habits. “When we think about trajectories, if you get into the habit of using these maladaptive coping strategies, you can build biological dependence on substances,” Vázquez said. “One storm can have this life-changing effect for a child.” 

The upshot is that isolating the behaviors that may eventually lead to alcohol and drug dependence is a first step toward protecting children from some of the more visceral consequences of surviving a disaster like a hurricane. The study found that children who had a supportive caregiver, friend, or teacher were less likely to turn to harmful coping devices. “This is consistent with the idea that the disintegration of social structures — be it climate change or otherwise — will impact the way people behave after a traumatic event,” Parks said. “It speaks to the particular vulnerability of youth in a resource-scarce area.”  

More research is needed to figure out exactly how to help youth survive the mental repercussions of hurricanes and other extreme weather events, Vázquez said, especially as climate change becomes more severe. “There’s going to continue to be intense storms with more devastation in low-lying areas like Puerto Rico that are more vulnerable,” he said.
