The cost of natural disasters might jump by 60% by 2050 according to a recent reassessment carried out by the public insurer CCR. If the resurgence climatic events have a heavy impact on financesit is also not without consequences on health.

According to a recent study, exposure to a large-scale natural disaster, such as a tsunami, has a impact on population health more than a decade later. To reach this conclusion, a new study was conducted by an interdisciplinary team of researchers in the United States and Indonesia. She revealed that women who lived along the coast of Aceh, Indonesia, when it was hit by the waves of the 2004 tsunami, had cortisol levels (stress hormone) lower 14 years later than other women. “The study connects the stress linked to exposure to the tsunami to “professional burnout “of the hypothalamic-pituitary-adrenal (HPA) axis, which manifests itself in low levels of cortisol over the long term,” details the press release.

“These effects are greater among women who reported high levels of post-traumatic stress symptoms for two years following the tsunami,” said Elizabeth Frankenberg, who, with Duncan Thomas and Cecep Sumantri, is leading a long-term investigation project into the effects of the tsunami. “An important finding is that people with low cortisol levels are in poorer physical and psychosocial health 14 years following the tsunamiproof of the long reach of the tsunami stress and its consequences,” emphasizes Duncan Thomas.
