Why do I keep waking up with numb arms

Probably your pillow is too flat and your arm gets trapped under your body. Been there.

Numb arms? Congrats, you're a side sleeper with a mattress that's too soft. Your shoulder sinks in, your arm gets pinned and boom—dead limb. Get a firmer mattress or a thicker pillow. Or just embrace the tingly wake-up call as a fun new hobby.

I had the same issue. Turned out my old memory foam was sagging in the middle. Replaced it with a hybrid and it stopped within a week.

Could also be your arm position. Do you sleep with your arm under your pillow? That cuts off circulation.

Happens to me when I sleep on my side without flipping. My arm goes numb and then I wake up and it's all pins and needles. I just flip over and it goes away. Not a big deal. But if it's happening a lot maybe see a doc?

What mattress do you have? That's the first question.

Yeah, a decade-old memory foam is basically a coffin for your arms. Time for a new bed, my friend.

Ten years is a long run. If it's sagging, your spine isn't aligned and your shoulders are taking the brunt. A firmer mattress with good edge support could help.

Also try sleeping with a body pillow. Keeps you from rolling onto your arm.

Or you might have thoracic outlet syndrome. Not to scare you, but numb arms at night can be a ne rve thing. Maybe worth a doctor visit if a new mattress doesn't fix it.

I second the body pillow suggestion. I'm a bigger guy too and that helped me stop waking up with dead arms.

If you're 250 lbs, you probably need a mattress rated for higher weight. Most standard foams aren't built for that and they break down faster. Look for something with a denser core.

Or just amputate. Problem solved. (Kidding. Sort of.)

Let us know what you ennd up getting. I'm curious.
