Austin's summer heat can affect mental health—particularly for people managing certain conditions, those experiencing housing insecurity and those who spend extended time outdoors, according to Dr. Ziyad Nuwayhid, chief medical officer at Integral Care, Travis County's mental health authority.
What's happening
Nuwayhid said conditions like schizophrenia can impair a person's ability to perceive temperature or recognize when they need water or shade, putting them at greater risk during extreme heat. Some psychiatric medications can also reduce the body's ability to stay hydrated, compounding the risk, he said.
People managing depression or post-traumatic stress disorder may find heat adds another barrier to daily functioning, while those with bipolar disorder may experience increased irritability and impulsivity, Nuwayhid said.
