OXYGEN'S SECRET JOB
When we think of oxygen, most of us immediately connect it to survival. We know it is essential for breathing, for fueling our cells, and for keeping us alive. But science is showing us something deeper: oxygen is not just a fuel—it’s a messenger. It carries information. The Science Behind Oxygen as Information Inside your body, oxygen doesn’t simply provide energy. Each molecule participates in signaling pathways, telling your cells how to function, adapt, and respond. Oxygen levels influence how genes are expressed, how blood vessels form, and how your immune system fights infection. For example: Hypoxia (low oxygen levels) triggers the body to release proteins that encourage new blood vessel growth. Normal oxygen flow tells cells to operate at balance, producing energy efficiently. Excess oxygen can even signal stress, reminding the body to protect itself. In other words, oxygen carries data that shapes the way your body works. It doesn’t just keep you alive—...
