Mortality from circulatory diseases
upin humans1Very low certainty
Summer heat is associated with mortality from circulatory diseases in humans (85,524 heat-attributable deaths (82,762–88,271); largest absolute cause-specific burden).
“Circulatory diseases accounted for the largest absolute burden, with 85,524 heat-attributable deaths (82,762-88,271) across the summers of the 20 years considered.”

Summer heat is associated with mortality from mental and behavioural disorders in humans (Heat-attributable fraction 14.47% (95% credible interval 13.55–15.39)).
“heat-attributable fractions were highest for nervous system diseases (14.93%, 95% credible interval 14.22-15.69) and mental and behavioural disorders (14.47%, 13.55-15.39).”
