Why am i been waking up from sleep feeling very tired
could be a lot of various reasons. Talk to your doctor and see if he can arrange a sleep test for you. May not be apnea but you could have other issues that can be detected with this test. Good luck.
You either are getting too much or too little sleep, or you could be suffering from sleep apnea (where you stop breathing for a few seconds all throghout the night) or other sleep conditions, if this continues and you know you sleep for atleast 7 hours you should see a doctor and be checked for sleep apnea.
could be a number of things.
do you smoke? are you on medications....? how is your diet? are you overweight in any way?
how much coffee do you intake? or any energy drinks... caffiene?
do you hydrate properly? how is you health in general?
do you snore? how much alcohol do you intake weekly?
maybe go see a doc.. tell them this (if it's been long term) and if the doc is smart they should check the blood pressure ( hypertension can make you real tired) and take a blood panel and see how your chemistry is.
then work on from there.
you could also be stressed and not feel it. alot of stress is underlying and doesn't surface and can effect you deprementally in many ways.
get some things checked out... also see about better sleeping materials.. futons are great, better support, natual materials can make a difference for some.. or a water mattress.
many things could contribute... start checking some of these options out if you've not already.
or you could have a REM restless disorder where when you rem your body becomes quite active.. or the opposite could be happening... some lack REM sleep and that can whoop you pretty badly too and make you very exhausted.
Maybe you're just hungry or have low blood sugar when you wake up. If you eat a lot of sugar every day, you'll probably feel bad in the morning because you need another fix.
