Every new car in the U.S. will be required by law to have tech that puts constant surveillance on the driver by 2027. AI in your car will determine if you're sober and fit to drive, automatically turning off the vehicle if it determines you're a danger on the road.

Reactive oxygen species, or ROS, are unstable molecules produced during energy metabolism. Most people only hear about them as damage, but that is already a distortion of the biology. Red light devices can increase ROS, and in a stable tissue that can be useful. Small increases can act as signals that trigger repair, antioxidant defence, and adaptation. But the exact same signal can become another layer of stress in a tissue that is already overloaded. That is the part the red light industry barely talks about. ROS is not automatically healing just because it is signalling. In a tissue that is already inflamed, oxidised, or near its limit, more signalling can simply mean more damage. That is the conundrum. The mechanism does not change, but the meaning of the mechanism does. The same ROS signal can support repair in one state and push oxidative stress further in another. Some people feel better after red light, while others feel wired, drained, or more inflamed. That is exactly what you would expect if the same signal can support repair in one state and add oxidative load in another. This matters because the body is not one uniform system. Different tissues can be repairing, overloaded, inflamed, or failing at the same time, which means the same device can be helpful in one place and mistimed in another. So red light is not acting on a blank canvas. It is adding oxidative pressure to a tissue that may be ready to use that signal well, or may already be too close to breaking point. ROS is not the problem. The problem is pretending a stressed tissue always needs more signalling.
