Have been sleeping 9 hours consistently and still waking up feeling tired/exhausted/groggy - what is wrong

Seeking Advice

For nearly two weeks, I’ve been consistently sleeping 9 hours each night but still wake up feeling tired, exhausted, and groggy. I suspect it might be due to iron deficiency, but can that really be the cause?

Iron deficiency can indeed lead to poor sleep quality, including symptoms like restless leg syndrome, which might affect your sleep. Do you experience uncomfortable sensations in your legs or an urge to move them while trying to fall asleep?

I’m not sure what restless leg syndrome is exactly. Could you explain more?

Restless leg syndrome involves uncomfortable leg sensations that compel you to move them, often occurring right before sleep. It can significantly disrupt your sleep quality. How well do you sleep generally? Do you find yourself waking up during the night, snoring, or waking up suddenly gasping for air?

I don’t experience those symptoms. I sleep through the night without interruptions and I’m not aware of any snoring or waking up gasping for breath.

In that case, it might be worthwhile to discuss a sleep study with your doctor. The study can determine if you have any underlying sleep disorders that aren’t immediately obvious, such as issues with your REM sleep, which is crucial for feeling rested.

That sounds necessary. What exactly is REM sleep, and when does it occur?

REM sleep is a critical sleep phase that occurs at intervals throughout the night, typically every 90 to 120 minutes. It’s vital for cognitive functions and overall health. Each REM phase can last up to 20 minutes, and missing these can leave you feeling groggy regardless of the total hours slept.

Thanks for the information. I’ll consider scheduling a sleep study.
