There is an ideal oxygen percentage in air for long-term health
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Evidence indicates that deviations from normal physiological oxygen levels, particularly hyperoxia, lead to increased oxidative stress and cellular damage, supporting the concept of an optimal oxygen range.
