What happens to brain after drowning?
Like Jewel, people who survive drowning may experience brain or organ damage ranging from mild to severe. This is also known as hypoxic brain injury (brain damage due to lack of oxygen).

Do dead bodies explode?
Once a body is placed in a sealed casket, the gases from decomposing cannot escape anymore. As the pressure increases, the casket becomes like an overblown balloon. However, it’s not going to explode like one. But it can spill out unpleasant fluids and gasses inside the casket.
Why do bodies bloat after death? Rigor mortis initially sets in and cells break down as the lack of oxygen and nutrients prevents them from replenishing themselves. When bacteria in the gut can no longer be kept in check, they start to reproduce and feed on the body. This produces gas that causes the abdomen to bloat.
