Brain Chemicals That Cause Sleep Paralysis Discovered. During the most dream-filled phase of sleep, our muscles become paralyzed, preventing the body from acting out what's going on in the brain. ... During REM, the brain is very active, and dreams are at their most intense.

Chronic worry and emotional stress can trigger a host of health problems. ... The fight or flight response causes the body's sympathetic nervous system to release stress hormones such as cortisol. These hormones can boost blood sugar levels and triglycerides (blood fats) that can be used by the body for fuel.

Body Decomposition Timeline. 24-72 hours after death — the internal organs decompose. 3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas.

But within a year all that is usually left is the skeleton and teeth, with traces of the tissues on them - it takes 40 to 50 years for the bones to become dry and brittle in a coffin. In soil of neutral acidity, bones may last for hundreds of years, while acid peaty soil gradually dissolves the bones.

In addition to various gases, a dead human body releases around 30 different chemical compounds. The gases and compounds produced in a decomposing body emit distinct odors. While not all compounds produce odors, several compounds do have recognizable odors, including: Cadaverine and putrescine smell like rotting flesh.

It's a survival mechanism: in the presence of something good, the brain releases four main 'feelgood' chemicals – endorphin, oxytocin, serotonin, and dopamine – and in the presence of danger, the 'bad feeling' chemical – cortisol – comes in.

Notions that the brain is a chemical soup in which not enough dopamine or too little serotonin contribute to severe depression helped pharmacologists design a series of antidepressants that work –although only in some cases.
