The singer was afflicted with altitude sickness Wednesday night after her show in Denver, Colorado, sending her to the hospital.
She posted a photo of herself with a mask and a face full of makeup to Instagram early this morning with the caption: “Altitude Sickness is no Joke! #hitThatHospitalSh, #artRaveDenver many true ravers crowd tonight.”
FYI: Altitude sickness occurs when you cannot get enough oxygen from the air at high altitudes. This causes symptoms such as a headache, loss of appetite, and trouble sleeping. It happens most often when people who are not used to high altitudes go quickly from lower altitudes to 8000 ft (2438 m) or higher.
