Fever is the temporary increase in the body's temperature in response to a disease or illness. At-home biomarker tests can screen for fertility, heart health, STIs, and certain cancers. It is caused by the loss of body fluids through sweating, and by lowered blood pressure due to pooling of blood in the legs. Though few studies have evaluated the efficacy of heat notification and response programs, one study concluded that during a 1999 heat wave Chicago more successfully mitigated adverse effects than it did during a 1995 heat wave (about 100 deaths in 1999 compared with approximately 700 deaths in 1995). Heat stroke is the most serious heat-related illness. Extreme levels of heat stress have more than doubled over the past 40 years.
