When levels of reactive oxygen species increase to dangerous amounts, it is known as oxidative stress. Further, this may be from environmental stress occurring outside of the body, like UV or heat exposure. When the body is in this state of stress, important cell structures can be damaged.
Reactive Oxygen Species
When cell systems are functioning properly, reactive oxygen species (ROS) are a natural byproduct of metabolic reactions that break down oxygen. Thus, this process results in ROS like peroxides and superoxides. These then serve important roles in homeostasis and cell signaling.
Eventually, high or prolonged oxidative stress may play a part in serious medical issues. For example, these include cancer, Alzheimer’s disease, heart failure, and much more. Therefore, it’s very important to detect this stress early and work in neutralizing these high levels of ROS.
