People who need to monitor their SpO₂ levels are primarily students and office workers. Long-term, high-intensity use of the brain can lead to hypoxia, so continuous monitoring is necessary. Physical stress, such as intense exercise, can also contribute to insufficient oxygen in the blood. People with sleep apnea should monitor their blood oxygen levels, as a lack of oxygen also affects poor sleep quality.
