If your hands fall asleep, it's a clear sign that...

Waking up with a paralyzed hand, sudden tingling in the extremities, or a leg falling asleep after sitting for a long time... These common phenomena raise questions. Is it simply temporary discomfort or a warning sign? Here's a look at the possible causes.
Tingling and Numbness: When Should You Be Concerned?

Rest assured, in most cases, these unpleasant sensations are completely harmless:

Staying in the same position for too long (such as a bent arm or crossed legs) can compress a nerve and create the impression of a "dormant" limb.
Carpal tunnel syndrome, particularly common in people who use their hands intensively (keyboarding, manual activities, childcare, etc.), often manifests as nighttime tingling.
A cyst or an old, poorly healed injury can sometimes exert pressure on nerve endings, reproducing these symptoms.
The solution? Gently moving the affected limb or simply changing position is usually enough to make these sensations disappear.
