After one sleep-deprived night, I'm OK the 1st day, tired the 2nd. Why?

Here's a pattern that happens to me a lot. Say I sleep 4-5 hours on Sunday night, instead of my preferred 7-8. I feel fine all day Monday, then sleep 8 hours Monday night. On Tuesday, I feel exhausted and mentally foggy. Is this pattern documented in others? Is there a physiological explanation? [more inside]

Preventing morning adrenal surges

I've realized that morning adrenaline and cortisol surges are largely responsible for my daily hours of panic and dread. While I know ways of soothing that after the fact, I want to prevent it altogether and am looking for supplements, medication, lifestyle hacks. More inside. [more inside]

Difference in facial appearance b/w healthy and unhealthy weight loss?

People who have low body fat due to anorexia, disease, etc., look visibly unhealthy. People such as body builders and actors who have low body fat look healthy. I guess I can understand that "little amount of fat over large amount of muscle" looks healthy while "little amount of fat over little amount of muscle" looks unhealthy, but since people generally don't lift weights with their faces, necks, etc., it would seem that their faces would look the same, but that's not the case. What causes the unhealthiness of anorexic/disease/etc. weight-loss to be apparent in the face and neck?

What next for a biochemistry / physiology PhD?

I'm a couple years off finishing a PhD that's been about half biochemistry and half electrophysiology at a top-ranked Australian university. The academic career path is definitely open to me - I've got a decent number of publications, heaps of teaching experience, blah blah blah - but I'm unsure that it's what I want to pursue.

Whose ears popped first?

I know why our ears pop, but I'm wondering when humans reliably began experiencing this sensation caused by anything other than having a cold. Today, we are most likely to feel our ears popping in a airplane or driving a car in the mountains. But before planes and cars, and besides the head colds and infected sinuses that have always been with us, what caused our ears to pop first? [more inside]

Trauma and Language

I have observed a new phenomenon in myself this year and noticed different patterns in how my brain interacts with language in the period after trauma. I have a lot of other stress reactions going on that seem to be hypothalamus stuff (loss of circadian rhythm, weird appetite things, feeling hot and sweaty) but am not sure how any of that plays into processing language. I would love to learn more about this, either from anecdotes or from a more research-based perspective. [more inside]

Heart Rate Monitoring on the Cheap

Dear Hive Mind, My friend (a graduate student in psychology) wants to collect physiological measures for her dissertation. However, she doesn't have much money with which to do so. What is the cheapest way for her to accurately record the heart rate of some undergraduates? How much more will it cost her to be able to export the data to a computer? Thanks 10^6, zscore

Best Anatomy/Physiology Videos on Youtube?

What size VFFs would accommodate the greatest number of students?

The high school level anatomy and physiology class I teach is going to do a unit on running and movement. Help me figure out what size VFF's to request from a generous donor to accommodate as many of my current and future high school students possible. If you wear VFF's, I'd appreciate you looking inside and giving me your traditional shoe size (US) and VFF sizes (I think we're getting KSO's). If you have any other great foot physiology sites or books (not mentioned here or here), I'd appreciate that info, too. I just wiped out my local library. [more inside]

Nervous and cardiovascular systems detail for high school A&P?

Hello! I am leading an Anatomy & Physiology study group for homeschooled teens.

Why don't adults enjoy dizziness?

Why don't adults enjoy dizziness like kids do? When I was a kid I remember thinking adults were boring for not enjoying the feeling of dizziness, and I vowed to always enjoy it :) Now as an adult, I can't stand it, and feel like throwing up. It seems most adults (if not all) feel the same way. Why is that?

Books on DVDs on exercise as body-exploration?

Are there any good DVDs or books that teach you exercise as a way of understanding and having fun with your body? I'm looking for a system whose focus is not primarily on losing weight or being healthy but on learning about your body and being able to do cool things with it you couldn't do before (gain better balance, stand on your head, improve your ability to drag furniture even), but that would also incidentally give you an excellent workout.

Hypotension/hypovolemia as a low-pass filter: I got cut, I went into shock, and then everything started sounding funny. I'd guess it was a 40 dB (±10) rolloff, which began near 200 Hz (±50) and left me with nothing above 1kHz. How in the world?

The Underwater Shiver-- What Causes It?

So I'm still trying to pinpoint this one (I keep forgetting to ask it, and Google turns up nothing)-- when one lies down in a bathtub, faceup, and submerges at least their entire ears, they shiver (it's more kind of an uncontrollable, brief spasm of the upper body and doesn't FEEL like shivering, but looks like it). It isn't related to the water temperature, as far as I can tell, and DOESN'T happen when facedown or swimming, etc. Or do other people not have this happen? Do you? I get it every single time, without fail, and have since I can remember. My mom knows exactly what I'm talking about, but my dad insists we're both crazy. Is this just one of those odd reflex reactions like coughing when you have something in your ear or sneezing when you get in the sun? (I also do that one-- always funny to explain to people :) ) Any idea what causes this, though?

physiology of sighing

What's the connection between a thought of regret, or of resignation to a negative situation, that causes humans to involuntarily fill their lungs and exhale slowly? Is such sighing learned behavior? Does every culture sigh for this reason? Animals sigh. When my dog sighs, is she laying there regretting she didn't roll in that dead skunk when she had the chance?
