00:00:02,040 --> 00:00:06,840
Speaker 1: Welcome to brain stuff from how Stuff Works, Hey, brain

2
00:00:06,880 --> 00:00:10,280
Speaker 1: Stuff Lauren vog Obam. Here, medical science continues to drive

3
00:00:10,320 --> 00:00:13,440
Speaker 1: home the risks of holding in an explosive sneeze, this

4
00:00:13,520 --> 00:00:16,000
Speaker 1: time in a b m J case reports discussion of

5
00:00:16,040 --> 00:00:21,120
Speaker 1: spontaneous throat rupture and deep tissue air bubbles. Here's what happened,

6
00:00:21,120 --> 00:00:24,480
Speaker 1: according to the papers authors. At the University Hospitals of Lester,

7
00:00:24,960 --> 00:00:27,720
Speaker 1: a thirty four year old man entered the emergency room

8
00:00:27,720 --> 00:00:30,960
Speaker 1: with reports of painful swallowing and curious popping sounds at

9
00:00:31,000 --> 00:00:35,400
Speaker 1: his neck, all following a suppressed sneeze. Upon closer examination,

10
00:00:35,560 --> 00:00:38,760
Speaker 1: doctors observed swelling and tenderness in the neck tissue, and

11
00:00:38,840 --> 00:00:42,320
Speaker 1: the popping sound proved to be crepitus. Crepitus is the

12
00:00:42,400 --> 00:00:45,440
Speaker 1: medical term for popping and crackling sounds under the skin

13
00:00:45,560 --> 00:00:48,559
Speaker 1: or in the joints. This is the creaking and cracking

14
00:00:48,600 --> 00:00:52,200
Speaker 1: of joints that becomes especially noticeable in older age. Crepitus

15
00:00:52,240 --> 00:00:55,360
Speaker 1: maybe due to several different causes, such as grating bones

16
00:00:55,400 --> 00:00:58,920
Speaker 1: and snapping tendons, but it's most famously summoned every time

17
00:00:58,960 --> 00:01:02,280
Speaker 1: you crack your knuckle. This causes gas suspended in the

18
00:01:02,320 --> 00:01:07,280
Speaker 1: joint snowvial fluid to form bubbles and burst. Unsurprisingly, Crepitus

19
00:01:07,360 --> 00:01:10,000
Speaker 1: is also the name of a California based death metal band.

20
00:01:10,920 --> 00:01:12,720
Speaker 1: But how does this relate to the thirty four year

21
00:01:12,720 --> 00:01:16,360
Speaker 1: old patients neck. The doctors identified crepitus from his neck

22
00:01:16,440 --> 00:01:19,560
Speaker 1: all the way down into his rib cage. These findings

23
00:01:19,640 --> 00:01:22,920
Speaker 1: suggested air bubbles lodged in the deep tissue and muscles

24
00:01:22,920 --> 00:01:26,440
Speaker 1: of the chest. Indeed, X rays revealed streaks of air

25
00:01:26,600 --> 00:01:30,480
Speaker 1: like the shrapnel of a detonated explosive. The hand grenade

26
00:01:30,480 --> 00:01:33,800
Speaker 1: in this case was the suppressed sneeze, which resulted in

27
00:01:33,880 --> 00:01:39,480
Speaker 1: spontaneous pharyngeal rupture. Doctors successfully treated the patient with antibiotics

28
00:01:39,520 --> 00:01:42,440
Speaker 1: and tube feeding, But as how Stuff Works has reported

29
00:01:42,440 --> 00:01:45,200
Speaker 1: in the past, a stifled sneeze can cause a host

30
00:01:45,240 --> 00:01:48,440
Speaker 1: of undesirable symptoms, including the rupture of blood vessels in

31
00:01:48,480 --> 00:01:52,360
Speaker 1: the brain. It seems ridiculous. A sneeze, after all, is

32
00:01:52,400 --> 00:01:55,480
Speaker 1: such a natural thing. It's just an expulsion of air

33
00:01:55,520 --> 00:01:59,440
Speaker 1: and mucus from the nostrils due to irritation. Children especially

34
00:01:59,520 --> 00:02:03,280
Speaker 1: sneeze boldly into their surrounding world, often with little consideration

35
00:02:03,280 --> 00:02:06,560
Speaker 1: of decorum, superstition, or the fact that Grandma's face is

36
00:02:06,680 --> 00:02:09,400
Speaker 1: right there in front of them. It's only as they

37
00:02:09,480 --> 00:02:11,919
Speaker 1: become adults that they learned to cover their sneezes and

38
00:02:12,040 --> 00:02:15,120
Speaker 1: in some cases attempt to stifle them by blocking both

39
00:02:15,200 --> 00:02:19,440
Speaker 1: mouth and nostrils. For certain, no one wants to unleash

40
00:02:19,480 --> 00:02:21,480
Speaker 1: a full blown sneeze at the theater or in a

41
00:02:21,480 --> 00:02:24,840
Speaker 1: crowded train car. It's a high velocity burst of mucus

42
00:02:24,880 --> 00:02:27,799
Speaker 1: and other particles, after all, and exhibits the very lack

43
00:02:27,840 --> 00:02:31,120
Speaker 1: of control we despise in our bodies. But as the

44
00:02:31,240 --> 00:02:35,080
Speaker 1: medical science illustrates, such a force is not contained without risk.

45
00:02:35,919 --> 00:02:39,480
Speaker 1: As Arthur Stanley P's explored in his nineteen eleven classical

46
00:02:39,480 --> 00:02:43,480
Speaker 1: philosophy paper The Open of Sneezing, beliefs in the ominous

47
00:02:43,560 --> 00:02:46,960
Speaker 1: or prophetic aspects of sneezing date back to ancient times.

48
00:02:47,440 --> 00:02:49,360
Speaker 1: These notions were well developed by the time of the

49
00:02:49,360 --> 00:02:52,239
Speaker 1: Greek poet Homer in the eighth or seventh century b c.

50
00:02:52,880 --> 00:02:56,080
Speaker 1: And subsequent thinkers and philosophers continued to pour over the

51
00:02:56,120 --> 00:02:59,040
Speaker 1: idea that while a sneeze might mean nothing, it could

52
00:02:59,040 --> 00:03:02,240
Speaker 1: also indicate the temporary presence of a divine force in

53
00:03:02,280 --> 00:03:10,720
Speaker 1: the sneezer. God bless you indeed. Today's episode was written
