What does cause of death mean when it reads as accidental self asphyxiation with no evidence of foul play?

"Accidental self asphyxiation" refers to a situation where an individual unintentionally restricts their own breathing, leading to death, often due to choking or suffocation. The phrase "with no evidence of foul play" indicates that there are no signs of intentional harm or external involvement in the death. This typically suggests the death was a tragic accident rather than a result of homicide or suicide.
