Does breathing into a brown paper bag trigger the brain to take slower deeper breaths?

No, breathing into a brown paper bag does not trigger the brain to take slower deeper breaths. While breathing into a paper bag can temporarily help increase oxygen levels in the blood, it does not directly influence or control the rate or depth of breaths taken by the brain. The respiratory centers in the brain regulate breathing patterns based on factors such as carbon dioxide levels in the blood, oxygen demand, and voluntary control.
