Dizziness upon waking in the morning can occur when blood glucose levels are low or blood pressure drops. If the sleeping environment is too enclosed and air circulation in the room is poor, oxygen deficiency may develop, leading to dizziness as well. Patients are advised to check for dizziness caused by arrhythmia, as irregular heart rhythms can result in inadequate blood supply from the heart and cause dizziness.
