We\u2019ve all heard of the \u2018fight or flight\u2019 response, where\u00a0your body reacts to stress<\/a>\u00a0or danger with a faster heart rate,\u00a0increased blood pressure<\/a>\u00a0and several other physiological changes. But there are some lesser-known symptoms that help keep you alive when danger strikes, and they can be a little bit odd. From\u00a0holding your breath<\/a>\u00a0for longer than you thought possible to shaking like a leaf after a scare, humans come equipped with a built-in survival toolkit. Here are some of the strange, clever and occasionally uncomfortable ways your body can respond to a life-or-death situation. (Picture: Getty Images)<\/figcaption><\/figure>\n<\/div>\n

1. Holding your breath<\/h2>
How long do you think you can hold your breath? 30 seconds? A minute? Actually, it might be longer than you expect. Cold water triggers the \u2018mammalian diving reflex\u2019, a physical survival response to being immersed in water. It slows your heart rate and redirects oxygen-rich blood to the heart and brain, limiting oxygen consumption by non-essential muscle groups. The diving reflex has been widely studied, and\u00a0a scientific review by Godek and Freeman<\/a>, published in 2022, explained that it was first described by British physician Edmund Goodwin back in 1786. They add that the dive response is activated with the immersion of the face, specifically the trigeminal nerve, in water. Other research, such as a 2021 study published in the journal\u00a0Frontiers in Psychiatry<\/a>, has found that activating the diver\u2019s reflex can\u00a0combat anxiety<\/a>\u00a0or stress, and you can feel these benefits by plunging your face into a bowl of cold water for 30 seconds.

2. Bending time<\/h2>
You know how people talk about \u2018time slowing down<\/a>\u2019 in certain moments? Well, when it comes to life-and-death situations, it\u2019s sort of true.\u00a0Researchers at the University of Iowa College of Medicine<\/a>\u00a0studied this phenomenon and found that out of 101 people who had encountered life-threatening danger, 70% experienced the sensation of time slowing down. Nobody knows exactly why this happens, but there are several theories. One of the most prominent is that the brain speeds up processing in high-pressure situations, making time feel like it\u2019s slowed down. However, other studies, including one published in the research journal\u00a0PLOS One<\/a>, suggest that time is only slowed down in individuals\u2019 memory of the event. This is because they remember the moment in greater detail, due to the brain taking on more information when afraid. Either way, the brain is working overtime to help keep you alive.

Rehearsing danger<\/h2>
You\u2019ve probably been told before that\u00a0dreams, along with nightmares, have meanings<\/a>. Many have experienced that common night terror of being naked on stage, and it\u2019s widely thought to be a signal of something causing stress or anxiety in your waking life. But nightmares may do more than reflect your waking fears \u2013 they could actually help combat them. In 2019, university researchers in Switzerland and the US found that\u00a0bad dreams improved the effectiveness of the brain in reacting to frightening experiences<\/a>\u00a0when awake. \u2018Dreams may be considered as a real training for our future reactions and may potentially prepare us to face real life dangers,\u2019 commented researcher Lampros Perogamvros.

Pupils dilating<\/h2>
Human pupils dilate in the dark to let in more light and help us see better, and the same thing happens when we feel threatened, helping vision temporarily improve and therefore avoid the oncoming threat. A 2016 study published in the\u00a0Journal of Trauma Stress<\/a>\u00a0found that individuals who met the criteria for PTSD showed more pupil dilation when showed threatening stimuli, while a 2004 study published in the\u00a0International Journal of Psychophysiology<\/a>\u00a0found participants\u2019 pupil dilation increased when completing a more complex task, suggesting a link between pupil dilation and mental strain.

Blocking out pain<\/h2>
If you become injured in a threatening situation, you might not feel the pain until you\u2019re out of danger, enabling you to fight, run or protect yourself. Dan Baumgardt, from the School of Psychology and Neuroscience at the University of Bristol, recently explained in\u00a0The Conversation<\/a>\u00a0how the brain can \u2018switch off\u2019 pain. He says that the periaqueductal grey (PAG), a structure in the middle of the brain, contains neurons whose role is to alter incoming pain signals. He wrote: \u2018Ever picked something in the kitchen that you suddenly realise is extremely hot? Sometimes that casserole dish or saucepan descends to the floor, but sometimes we are able to hold on just long enough to transfer it to the stove-top. This action may be underpinned by the PAG shutting off the sensation of clasping something too hot to handle, just long enough to prevent dropping it.\u2019 (Picture: Getty Images)<\/figcaption><\/figure>\n<\/div>\n

Shaking uncontrollably<\/h2>
‘Shaking like a leaf’ is a phrase often used to describe people experiencing fear, but it’s not a sign of weakness. According to the\u00a0Fixel Institute for Neurological Diseases<\/a>, shaking from fear is all part of an \u2018internal alarm system\u2019 to help you react to a threatening situation. Adrenaline is released, increasing heart rate, tightening muscles, and redirecting blood flow from your skin to your larger muscle groups. This flood of energy can make your body tremble because it\u2019s getting ready to move fast. (Picture: Getty Images)<\/figcaption><\/figure>\n<\/div>\n

Smelling fear<\/h2>
It\u2019s often said that animals can \u2018smell fear\u2019, and while humans can\u2019t consciously identify if someone is afraid just by taking a whiff of their musk, there\u2019s some evidence to suggest that we can detect fear in a person\u2019s sweat. For example, a 2008 study in the journal\u00a0Nature Proceedings<\/a>\u00a0had novice skydivers wear absorbent pads on their first tandem skydive, and then later while running on a treadmill. New participants then smelled each of the sweat samples, and the researchers found that when sniffing the skydiver samples, the amygdala part of the brain was more active than in the group who smelled the treadmill samples. The study concluded that humans can subconsciously detect fear from the smell of sweat. (Picture: Getty Images)<\/figcaption><\/figure>\n<\/div>\n
