Why do you feel like crap after waking up from a nap?

When you sleep you go through different cycles, most notably, REM. This period is where you are deepest asleep and you dream.  Its the climax of your sleep cycle. When people nap, they generally don't go through their entire cycle, hence they wake up and don't feel as though they slept at all.  Generally, you need to sleep at least 3 hours to go through your entire sleep cycle, anything shorter than that, and you will feel groggy and tired when you wake up.  Instead of taking naps, try just resting and relaxing without sleeping, for 20-30 minutes.  That is generally the best thing to do when you are tired during the day.  It refreshes you, and won't wreck your sleep schedule, like naps will do.

If you feel constantly down, sad, depressed and can't figure out why, if when you wake up in the morning you just don't want to get up, nothing you do seems to make you happier, the things you enjoy about life seem difficult to do, you want to cry just facing the thought of going to work or school. Some physical symptoms include great fatigue, or changes in your sleep or eating habits (perhaps you're never hungry, or maybe you're always binging on tons of food; or you can't sleep nights, or you're sleeping 18 hours a day). These symptoms can occur at any time, but if they keep going on for a while, maybe after a month, you have a good chance of suffering from depression. I do hope this helps!

definitely sounds like a panic attack.  \n\nWhat is happening is that you become "scared" of the feeling of panic there fore you are sent into a "panic attack".  Also you are internalizing a lot of stress and you're body needs an outlet so it sends a large release through an attack.  After your "attack" is over do you feel sleepy?  Well that the feeling you get after an attack along with sweating.  You need to release more emotion, and stress, try crying, try exercise, try talking to people about your problems, try getting better sleep as well.  The way I overcame them is to control them and stop letting them control me.  If I felt a panic attack coming on I take deep breaths close my eyes and think for a minute.

It could be due to your lifestyle.. i used to have the same problem. I went to the doctors and he just suggested exercise daily, eat healthier and try and cut out refined sugars. I got real good sleeps and woke up feeling awesome :)

Because you probably have a messed up sleeping schedule like me. You go to sleep late, wake up super early then take a nap somewhere in between which starts the cycle all over the next day.<yawn> <<<Did that help?

Start by thinking that we are made to be healthy.  So not feeling right is not the way it is supposed to be.  If we wake up in the morning, but stay in bed, falling back to sleep, we are not really getting much rest because our sleeping is so light.  So better to get up when we wake up.  And get busy right away.  Start drinking something, like a cup of coffee.  Liquid does a lot to help us feel more at our peak.  Getting enough liquid is important every day.  One other reason for not feeling right is not going to the bathroom, number 2.  Those are the routine reasons for headaches.  Have an outstanding day.  Stay healthy and happy.

It depends on what is ailing you. Most of the time, If you start moving around more and doing things, you'll feel better. Now, if it's a matter of morning sickness, it varies. If you feel sick because of this, you should have unsalted crackers beside your bed, on your nightstand, so that when you wake up in the morning, you'll have them before you get out of bed. Eat a couple and let them settle, before trying to attempt getting out of bed.

If you feel sleepy after eating, particularly after sweet or bakery products, you are normal. Eating sugary foods causes your brain to make large amounts of the neurotransmitter, serotonin, that makes people fall asleep naturally at night. Eating sugary foods or those made from flour, such as bakery products or pastas, causes blood sugar to rise higher than normal. This causes your pancreas to release large amounts of insulin, which drives one of the protein building blocks called tryptophan from your bloodstream into your brain, where it is converted to serotonin that makes you feel sleepy. Many people can avoid feeling sleepy after eating by restricting foods high in sugar and flour. When it is important for you to be alert, eat foods that do not cause a high rise in blood sugar, such as vegetable salads, nuts, seeds, meat, fish and chicken.

Sort of. Sometimes I know when i'm dreaming and I try to wake myself up but I feel like I can't move or talk. I'll lay there for a few minutes struggling with myself until I finally snap out of it abruptly. It's really strange.

The only thing I can think of is the post birth blues, where you feel like nothing is okay, and like it's all too much.  You feel like that litle person has taken away a beloved part of your life.  It is normal, and hormonal, and does go away.  Before birth, I don't know, I would ask your doctor if it is normal, or if you should be concerned.  I have heard of it, so it must be farely well known.

Everybody will react differently. Are you sure its from the session or is it just a coincidence? It doesn't mean anything, just that your body was really tired and drained after the session.

Its possible you aren't getting enough sleep.\n\nIts possible you aren't eating right.  Maybe you're not getting enough protein or even fat, both of which can make you feel a little more energetic.\n\nIf there's any chance you have a little depression you would not always have the energy to work out.\n\nIf you live under unrelenting stress its possible your adrenal gland has "run out of juice" and cannot produce sufficient cortisol for you to be able to exercise without feeling depleted.  ("Adrenal fatigue" causes people to feel depleted rather than invigorated by exercise.)

Your blood sugar could be fluctuating. That can give you a feeling of nausea. \n\nI once ate a 2 course meal yet 30 mins later my blood sugar was still dangerously low. Does make you feel pretty unwell I agree. Get it checked out would be my advice.

There's a hormone called insulin which is secreted by the pancreas which helps decrease your glucose (blood sugar) levels.  After a large meal, there is a huge spike in post-meal insulin response which overcompensates and produces more insulin than is necessary to quickly lower blood glucose.  This in itself can make you feel tired and hungry again.  At the same time another hormone is released called cholecystokinin. One of the functions of this hormone is to make you feel full. But it also activates the areas in the brain involved in sleep.  Finally, the level of an amino acid called "tryptophan" increases, it is converted into "serotonin" in the brain. Serotonin also does a very good job of making you feel sleepy!\n\nBest advice:  Eat more frequently and eat smaller meals to avoid this effect.
