Five years is actually not a long time for science to understand a process as complex as the pathways of the oil after a large spill. Some of the impacts of the Deepwater Horizon spill on the marine life and ecosystems of the Gulf of Mexico will only become visible in future years. We use oil products daily.
First the researchers examined the effects of lowering cortisol to below a normal (or baseline) level. Then they compared the effects of low, medium, high, and very high cortisol levels in patients undergoing cardiac surgery, a procedure that causes a lot of inflammation.
Chronic Stress Can Damage Brain Structure and Connectivity. Chronic stress and high levels of cortisol create long-lasting brain changes. Neuroscientists have discovered how chronic stress and cortisol can damage the brain. A new study reconfirms the importance of maintaining healthy brain structure and connectivity by reducing chronic stress.
