Is it normal to feel flustered and have jumbled thoughts when you're really tired? 7 hours sleep and up all night, now I feel foggy and zoned out.

Absolutely: Your brain needs to recharge. There are chemicals up there that need to re-set, and this happens during sleep. Your brain is now running on an empty tank, on a dying battery. That's why it's never good to pull an all nighter before a test - you won't be able to retrieve the information the next day! . You need sleep - sweet dreams..........Zzzzzzzzzzz. ...Read more

Why is it that I feel tired after 8 hours of sleep but fine after 5 or 10 hours?

Why is it that I feel tired after 8 hours of sleep but fine after 5 or 10 hours?

Sleep: Some of it could be due to sleep inertia as well as the stage of sleep you are waking up from. Typically if you are woken up from a deeper stage of sleep you may still feel a bit more tired rather than a lighter stage of sleep. Also, studies suggest that we seem to be a poor judge of how we feel after being sleep deprived, so you may be sleepier than you think. ...Read more

I sleep for 12 hours and still wake up tired. Sleeping 8 hours doesn't help. What should I do?

I sleep for 12 hours and still wake up tired. Sleeping 8 hours doesn't help. What should I do?

See your doctor: Sounds like you're putting in the hours, but still feeling tired. This could mean the quality of sleep isn't good. I'd avoid alcohol before bed, as well as Benadryl (diphenhydramine) and those pm cold meds (they can put you to sleep, but it isn't great sleep). If you snore a lot, ask your doctor about sleep apnea. Your family doctor should feel comfortable evaluating you further. Good luck! ...Read more

I am tired after 9 hours of sleep. Should I take a nap to refresh if so for how long?

I am tired after 9 hours of sleep. Should I take a nap to refresh if so for how long?

No: You should work to adapt a very regular sleeping pattern -- even over the weekends -- to maintain optimal health and awareness and productivity in all that you do. 9 hours of sleep is more than enough for the average 16 y.o. male. Unless you are engaged in very intense /long duration /multiple frequency physical workouts, then the napping is not necessary. (i.e. world class athletes). Good Luck. ...Read more
