Yawn. It’s one of the best things you can do for your brain
- weegee 17y agoreading that made me sleepy
- alanthonyc 17y agoHow many of you yawned when you read the title to this post?
- rms 17y agoI tried it but can't decide if any relaxation I felt was placebo or not.
- GavinB 17y agoThe relaxation was real, even if the cause was a placebo. I believe this is the only time in the history of HN when it won't be rude to say . . . yawn
- Paton 17y agoI yawned at least 6 times
- edu 17y agoI did, and it worked :) Really feel energized now :)
- julsonl 17y agoI guess I was not alone...
- nsrivast 17y agoStrangely, I yawn aggressively when lifting weights and when I'm nervous (usually before a public speaking event).
- nagrom 17y agoIt could be that your heart rate increases (exertion, nerves) and this is your body's way of increasing oxygen in the system. That'd be my guess, anyway.
- electromagnetic 17y agoI was always told by biology teachers and such, from junior highschool up to college professors that yawning is stimulated by a decrease in oxygen in the brain. A decrease in oxygen can be related to a number of things, one being exercise (which will reduce overall body oxygenation), another being concentration (certain areas of your brain can locally reduce its oxygen levels by working more than normal, likely when you shift from using one area of your brain to another), another is tiredness due to reduced respiration and heart rates, and finally by waking up as your body tries to increase its oxygenation levels to cope with rapidly increasing demands (this can be effected by what state of sleep you're in: light, deep or REM; typically deep sleep would cause the most yawning when being woken up from). I'd certainly believe you could induce yawning from anaerobic exercise. If it was induced by aerobic exercise, I'd say you're not doing the exercise properly!
- christopherdone 17y agoI am the same. I yawn when nervous or scared. I used to yawn when walking past a bunch of thugs at school in the mornings. People at work tend to yawn when I talk to them.
- giardini 17y agoDitto for me, especially on squats. About 8 seconds after my first lift in a set, the lack of oxygen hits me hard: I first yawn and then begin breathing faster. This is when going straight into the squats with no warmup whatsoever.
- papersmith 17y ago"All you have to do to trigger a deep yawn is to fake it six or seven times." Does this work for anyone else? Maybe I'm doing it wrong.
- adammichaelc 17y agoWorked for me
- slig 17y agoI was very skeptical, but it did work for me.
- johnfn 17y agoI only have to fake it like once or twice, actually. It should definitely work.
- voidpointer 17y agoAfter ten fake yawns I felt more like I had been hyperventilating - I'm clearly doing it wrong :/
- ptn 17y agoDidn't work for me.
- agbell 17y agoAuthor of HOW GOD CHANGES YOUR BRAIN
- codexon 17y agoAndrew Newburg is director of Penn’s Center for Spirituality and the Mind. This essay is from the book: HOW GOD CHANGES YOUR BRAIN
- amix 17y agoSo what... He has looked at how "believing in God affects our brains" - his idea that yawning could be a good thing is still valid and interesting. He is a neuroscience professor (but then we'll fall into "Appeal To Authority"). Anyhow, I think we should stick for what he is saying now, and not what he has said or researched in the past.
- mattmaroon 17y agoIn that case, more articles about Lisp please :)
- onoj 17y agoIt irks me that while the story is interesting and potentially inspiring, the idea that this guy has a god fixation means I have to disregard it. Why don't these people do double blind studies (in this case with MRI) to find out if what they are saying is actually true rather and just post as if it was true.
- antirez 17y agoThe feeling of Yawning on purpose is not the same as yawning spontaneously :)
- mdolon 17y agoI've always found yawning very intriguing, and how people often get triggered to yawn as others around them are yawning. And how I just yawned at the thought of that!
