Why do you start yawning during exercise?

User Avatar
When you yawn, it's your bodies way of telling you, "I need more oxygen". So if you yawn more when you're exercising it's because your heart rate is up and you're using more oxygen.

When you yawn why does the next person yawn?

For the same reason that people look up when you look up. You can call it the power of suggestion. its to do with the mide to find out more i would proberly go on health websites or if your that conserned go to doctor or your actual GP yawns are very contagious. so when we yawn we got it from someone and gave it to someone else. Because when you see some one yawn that makes you sleepy and you yawn unless you hold it in We yawn because it it a signal from our bodies telling us that we are tired. Yawns are not really contagious, it is just a myth. I've heard you yawn because your body is telling you that you need to keep breathing! it is because your breathing slows and your body catches up, unless it is forced yawn. Have u ever realised that u smile when someone else smiles at you.... similarly you yawn when you see someone else yawning.This is a stimulation reaction by you stimulii....this action is stored in your brain....you yawn every time you see someone yawning and also when you feel sleepy or drowsy.....when you feel either sleepy or drowsy. Your respiratory system starts taking in more of carbon di -oxide and less of oxygen...when your brain realises this it commands your body to yawn in the process more of oxygen is taken in to reduce the large amount of corbon di oxide in the body.Therefore you yawn every time you see someone yawning and also when you hear,say or read the word 'yawn'...i bet as you are reading this you must be yawning!!! Yawns can be very contagious. Even just thinking about yawning can make you yawn. I actually started to yawn answering this. Its just your brains way of working. The scientific answer is due to minor neurons in your body. When someone yawns and you yawn it is contagious but unharmful daily thing in your life. Studies showed that your brain isn't getting enough oxygen so you yawn and when someone else yawns your brain actually thinks theyre taking your air. One states that yawning occurs when one's blood contains increased amounts of carbon dioxide and, therefore, becomes in need of the influx of oxygen (or expulsion of carbon dioxide) that a yawn can provide,[5] but studies have since shown it to be either incorrect or, at the very best, flawed.[7] Yawning may, in fact, reduce oxygen intake compared to normal respiration, not increase it.[8] Another speculated reason for yawning is the desire to stretch one's muscles.[9] Yawns are often accompanied by the urge to stretch. Prey animals must be ready to physically exert themselves at any given moment. Muscles required to do this function more effectively when stretched, which is why human athletes stretch before exercise. Considering the increased amount of oxygen the body needs to sustain physical activity, it may be that, to perform best, the lungs and throat muscles need to be "limbered up" as well. Therefore, yawning could be the body's way of helping to keep the body ready for action. There have been studies that suggest that yawning, especially psychological "contagious" yawning, may have developed as a way of keeping a group of animals alert.[10] If an animal is drowsy or bored, it may not be as alert as it should be to be prepared to spring into action. Therefore, the "contagious" yawn could be an instinctual reaction to a signal from one member of the "herd" reminding the others to stay alert. Nervousness has also been suggested as a possible reason. Nervousness often indicates the perception of an impending need for action. Anecdotal evidence suggests that yawning helps increase the state of alertness of a person-paratroopers have been noted to yawn in the moments before they exit the aircraft because you both have different bodies working I don't. It is contagious no one knows Improving answer: It is theorized that when we were still apes that yawning was a way of signaling the rest of the group that it was time to settle down, relax, take a nap. People have a type of Hormone called Melatonin. This hormone promotes sleep, which means it makes you tired, allows you to sleep. Melatonin is found in everyone, specially teenagers, they have an extremely high ammount of melatonin. What I think is going on, is that when a person yawns, the melatonin gets released and spread through the air, hitting someone else with low amounts of melatonin, and promoting them to get tired. Because you want to do the same thing as the other person Edit: There is an actual scientific reason as to why we do this. Here is the direct order of which the action takes place: 1. Person observes yawn 2. Sensory input of the brain deactivates left periamygdalar region 3. Subject yawns in response. It is mainly social empathy in which causes this reaction to viewing another's yawn. Hope this helped. yes, because it is a natural instinct for people to yawn when others do! i heard that cave men didnt know how to talk so they would comunicate by showing there teeth. if you yawn you see there teeth. right? so this is why you yawn when you see someone else yawn!!!

Asked in Hair Loss and Treatment, Hair, Yawning

Does leg hair grow when you get goosebumps?

User Avatar
I don't usually post answers on these things, but I'm getting tired of hearing my girlfriends tell me that their hair grows faster when they get goosebumps, so I figure I'll just clear this up once and for all. No, goosebumps do not make hair grow faster. It is a myth that has been fabricated and spread around by women (and some men) who feel that their skin is prickly when they get goosebumps even if it was perfectly smooth just moments before. So, lets think about this logically and scientifically. Every hair in our bodies is rooted at the base of a hair follicle, which is located just under the surface of the skin. When we shave, what we are doing is trimming, or shaving the hair that is just above the skin. Goosebumps occur when the hair follicles contract and squeeze together causing the base of the follicle to be pushing up, and along with it, the unshaven hair that was sitting under the skin just a second ago, but is now pushed above the skin, giving us that prickly feeling. The important part to remember in all this is that once the goosebumps go away, the contracted follicles that are pushing the hair up relax, bringing the hair back down under the skin, because the hair is, of course still attached to the base of the follicle! And so was abolished the goosebump/ fast hair growing myth☺

Asked by Alexandra Russel in Yawning

Why are yawns contagious?

User Avatar
We can’t say for sure, but there are several possible explanations. One potential explanation comes from research out of the University of Nottingham, which suggests that contagious yawns are prompted by automatic, primitive reflexes in the part of the brain responsible for motor function. Other researchers think it has something to do with empathy or social cues. "Researchers have seen that yawning may not be as contagious to people with autism or schizophrenia," Meredith Williamson, clinical assistant professor at the Texas A&M College of Medicine, told Vital Record. Individuals with these conditions can struggle with empathy. A 2013 study did find, however, that children with autism experienced contagious yawns as often as non-autistic children when made to focus on the yawner’s face, suggesting social cues, rather than empathy, are at play. "It's multifactorial," Williamson said. "It could be partly an innate form of communication or it could be related to empathy, or a bit of both combined with other factors." Further research would be needed to pin down the exact causes.
Asked in Care of Fish, Betta and Siamese Fighting Fish, Yawning

Do betta fish know when they are full?

User Avatar
They will over feed but wont eat everything that you put in there. Just put in enough food so that all of it is eaten in 5-10 minutes or so. Any more and the excess food or fish poop will foul up the water quickly. Yes, they do. They tend to swim away from the food and ignore it or they might just keep eating. Try 1 flake/pellet to see if they are hungry and the put in 3-4 more in. Some good snacks-that can substitute for normal food-are freeze dried shrimp, live brine shrimp, live blood worms and freeze dried blood worms.

Why do people yawn when they see someone else yawn?

User Avatar
Answer (maybe) This is a nervous reflex of our brain, just like when someone tells you that he/she is hungry, even if you're not, you'll suddenly feel hungry as well. we tend to yawn when we see someone else yawn because we somehow connect to that person's mind when he/she's not having right amount of oxygen in his/her body Edit: Another possible scientific reason as to why we do this: 1. Person observes yawn 2. Sensory input of the brain deactivates left periamygdalar region 3. Subject yawns in response. It is mainly social empathy in which causes this reaction to viewing another's yawn. Also: When you see someone else yawn, it's because their brain thinks they are low on oxygen so they open up and yawn to get more. Then, your brain thinks that person is stealing your oxygen and sealing it off from you, so your brains reaction is to yawn and the chain goes on and on and on... Hope this helped.

Why do you yawn too much at work?

User Avatar
It isn't because you are tired, it is because your blood lacks oxygen. When you've been idle too long and suddenly move, you can find yourself yawning later on. That's why a person yawns after waking up in the morning. Yawning adds oxygen to the blood. If it bothers you, try deep breathing.
Asked in Yawning

Why do we yawn?

User Avatar
Yawning It is actually still an unknown mystery of life. Though there are good hypotheses supporting why humans and animals yawn, they are not conclusive. Any explanation about why we yawn will have to explain a number of interesting observations: Yawning occurs even when oxygen and carbon dioxide levels are normal. Yawning may make others yawn (that is, it seems "contagious") and may indicate behavior based on social cues. Other hypotheses: One is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood (This theory could be true, because I've never yawned while playing sports or running a mile before.) Most people think it is that you are tired or there isn't enough oxygen coming to the brain. From recent studies it is because your head is over-heated. Another person noticed that he had been sitting for about half an hour being bored and dreamy. When he stood up, he started yawning 2 or 3 times. Maybe his body was doing the opposite of maintaining homeostasis, preparing for an increased heart rate when his body stood up, as if about to start moving and needing oxygen.

Do lungs heal after you stop smoking?

User Avatar
No, but they will not pull so hard on the leash afterwards. It is believed that over a period of several years, a lot of the visible damage is repaired - so much of the tar, etc, in the lungs is eventually removed - but it depends on how long you have been smoking for, and how much other damage was done.
Asked in Yawning

Why do you yawn while working out?

User Avatar
Well, for one thing we don't even know WHY we yawn. A quite plausible theory is that we yawn to get more oxygen because our tired bodies can't gain enough through normal breathing. Another one is that it's a way to relieve tension and stress. Yawning is almost always a sign of sleepiness and is common in the morning or late at night. When you work out remember to have plenty of rest, food and water beforehand.
