Tucson's record setting heat wave might be taking its toll on our mental health.
University of Arizona psychiatry professor Rohit Madan is studying the impact of summer Seasonal Affective Disorder. He notes the extreme weather can contribute to feelings of anxiety and depression.
"Now people can't follow their daily routines, they can't follow the things they plan, and these disruptions contribute to these mood changes," Madan said.
Seasonal Affective Disorder is usually associated with winter weather that forces people to stay indoors. Madan says its summer counterpart adds longer days of discomfort and more sleepless nights. The uncertainty of how long the heat wave will last can also be a factor.
