How a 45-minute sauna led to severe heat stroke and a fortnight in hospital: case report

What should have been a relaxing stretch in a sauna turned out to be cause for a 12-day hospital stay for a woman in her early 70s.
Doctors from Birmingham’s Heartlands Hospital in the UK warn that staying in a sauna for too long can put people at risk of heat stroke.
The rare case of classic heat stroke with multiorgan failure and seizures secondary to prolonged sauna use was published in BMJ Case Reports.
The patient was found unconscious in a gym sauna after doing stretching exercises there for about 45 minutes.
