I kinda like your mom.

Mothafuckin circadian rhythms BITCH!

You! Yes you! I find your comments interesting, intelligent and you seem to be excited about what you're talking about!

I like that!

Have a cookie!

I understand that (thanks for the insight) But do you think its more of what time your body is used to sleeping, rather than an actual time? For instance, during the summer I tend to sleep around 2-4 am, and wake up around 12-3 pm. Every day.

But I'm kinda weird, so it could be just me..

It can vary, yeah. The body is automatically set to sleeping in the night and waking in the day, it's an evolved trait. But say for instance you do shift work, and you work nights. The body can adjust so that it's possible for the person to function through the night and sleep through the day, but it's neither as good for you or as efficient as a regular sleeping pattern.

I think what you're talking about is more sleep behaviour though, the hormone levels don't affect the sleeping/waking to the level that you NEED to sleep at midnight. The body has a minimum requirement for sleep and will try to get it even if it's daytime, the brain, etc, needs rest so the body won't wake itself up until it feels that it's ready.

Obviously tiredness also depends on energy use, amount of time awake, and all that stuff. The hormones are just aids in sleeping and waking, and the sleep-wake-cycle is a guideline.

I'm currently shattered so I'm not sure if that made sense, but hopefully it helped haha.

Made sense enough. Did you wiki this...or are you just smart? I'm a little jelly.

It's 2 years worth of A-Level Psychology haha! It's nice to be able to use it outside of a class or exam room...

We had to study the sleep-cycle and hormones because it relates to the brain and that sort of thing, and it links into sleep disorders, etc... I thought it was odd at first, I thought we'd just be doing schizophrenia and stuff. But there's a lot more too it, bloody fun to study though if you enjoy it like I did.

Wow, seriously?! I plan on studying Psychology. I'd like to be a therapist.

It's a good subject to study. Some aspects of it are hard (I struggled slightly with Schizophrenia and our module on Stress, I got them eventually though haha) but if you can do it then go for it, and good luck with becoming a therapist!

i want to challenge that somehow. i work nights and im fine. i want to have a kid and raise him to be as nocturnal as me

You can challenge your body's sleep-wake-cycle by going on holiday. Sounds odd, but you know what jet-lag is right?

Well, seeing as the cycle is set for the environment you're in now, if you were to travel in a short space of time, your body would have to adjust. If you travel to a different time-zone (for instance I'm in the UK, so if I travelled to New York I'd be a fair few hours out), then your body will not have adjusted yet and you will experience jet-lag. Jet-lag means that you will be tired during the day and awake at night basically (if you travel out far enough), because the day/night cycle there is different from your internal clock. Then it's just a matter of waiting for your body to adjust to that area's day/night cycle and bam, no more jet-lag.

There's more to it than that, but that's basically it. There's two types of jet-leg, phase delay and phase advance, one of which is more easy to adjust to. But I'll leave it at that... so yeah, jet-lag seems like a good way to challenge your body's sleep-wake cycle.

Then I'm just plain weird. I've always slept during the day. Even when I was a kid. I couldn't sleep at night. My body just refuses to do it. Made going to school difficult. I found working third shift, sleeping during the day and up at night, works so much better for me.

Individual differences man, individual differences :P

If you want to sleep at night though, try taking melatonin. It's basically the hormone but consumable and basically has the same effect, just whenever you need it.

Here, have an internet

You are completely right however, the circadian rhythm is actually a 25 hour cycle but since we go by 24 hour days it kind of adapts itself to a 24 hour cycle.

You're missing the point man, the sleep-wake cycle isn't EXACTLY 12 hours of each, I never said it was. The hormone levels aren't definite, I mean can keep yourself awake/stay asleep if you try. The hormone levels serve as guidelines, i.e. sleeping when it's dark and waking up when it's day time, hence the 12am - 6am, and aid sleeping/waking. But everyone is different, and so their sleep-wake cycle would be different... the point is, it's a roughly 24-hour cycle that consists of time awake and time asleep, that's influenced by hormone levels and outside influences, as well as a few other things.

That'sTheJoke.jpg

I've never seen the show, so I didn't know... I just thought she was trying to be funny

Plus, I needed to put my two years of Psychology to use.

Also, here's the .jpg you're looking for (probably)

I've never seen the show either, but it was kind of easy to tell that that was the joke, but I know you just wanted to show everyone your superior intelligence :D
Also thanks for the pic

Haha, but of course. I like using the things I learnt during my education... it makes me feel like it was worth it :')

No worries dude

You need to stop people from shooting inside of you.

i think my body might follow a different kind of cycle. every time i go to sleep at midnight or earlier, i can only get 8 hours of sleep, then i wake up fully refreshed and not even being able to sleep anymore even if i try. if i go to sleep at 4 AM which i've been doing a lot recently, i wake up around 12, so i get 8 hours again. i pretty much can't "sleep in" or sleep all day, even if i try to force myself to. is this normal? i have friends who can sleep 15 hours a day if nobody bothers them. is that normal? you said 12 hours asleep but i can only do 8 hours

There could be many different reasons as to why you sleep for 8 hours. It could be your age, if you're a teenager then you still need more sleep than an adult (we average 6 hours) so that could be one reason. Another reason could simply be individual differences, it might just be who you are.

I never studied periods of sleep in depth so I can't give you a definite answer on this one, but you're normal. So don't worry haha, the reasons I've said are probably correct and there's nothing unusual about either. I have a friend who's up before 10am no matter what, so he's like you in a way. But yeah, don't worry about it... you're getting the sleep you need (which is actually part of the Restoration theory of sleep I think, basically the body gets what amount of sleep it needs so that it can rest neurons and repair things and then you wake up, or at least I'm pretty sure that's how it goes), so I wouldn't worry. It's all good.

well i am 18 so i guess that is a good explanation. thank you for such an in-depth response

Check 'em!

What he said is not wrong in the slightest, there was no need for him to say it can be changed. Thats a different situation.

I've been looking for the longer version for a while. Thanks for that!

np

still not that bad

does she have a male pelvis? i feel like i'm looking at a man's body with tits slapped on

i used to agree with you, then i saw comment #32

Yes I do.
