Hot weather can leave almost anyone feeling drained, but for people already struggling with chronic stress, the effects can feel much worse. Many people describe this experience as adrenal burnout, a term often used to explain persistent fatigue, brain fog, and low resilience during stressful periods. While adrenal burnout is not an officially recognized medical diagnosis, healthcare experts acknowledge that chronic stress, poor sleep, and lifestyle factors can create symptoms that become more noticeable during extreme heat. When temperatures rise, dehydration, increased sweating, and physical strain can amplify these issues, making daily activities feel significantly harder.
