Sauna users urged to hydrate after woman suffers heart attack Sauna users have been urged to stay hydrated after a woman in her 70s had a heart attack after suffering from severe heat stroke.
Medics saw the woman in hospital 26 days after the heat stroke and found she had "returned to her baseline health status" but was still suffering from fatigue.
The unnamed woman, who used the gym daily, suffered a heart attack, seizures, liver injury and kidney injury, among other conditions.
Experts from Birmingham Heartlands Hospital described how the patient was in hospital for 12 days after she was found unconscious at an indoor sauna in her local gym.
The woman regained consciousness two hours after returning to normal body temperature, but she was confused and drowsy for two days.
