Certain Sleeping Positions
With regard to hand numbness, it’s always a good idea to keep external factors in mind when considering the cause. For example, those who wake up with numb arms or hands likely get it from an awkward sleeping position. Those who frequently sleep on their side will use their arm as a headrest — and the pressure eventually causes numbness over time. It’s one of the most common causes of hand numbness, as some people have difficulty sleeping in any other position but the side. For example, those who habitually snore loudly (possibly through sleep apnea) will have to sleep on their side to avoid blocking the throat. As a result, the most comfortable position often involves resting their heads on their arms.
Hand numbness from certain sleeping positions is usually nothing to worry about, but if done over a long period, the constant pressure could lead to some issues. Some pillows are specifically designed to help people sleep on their sides, so you won’t have to use your arm as a headrest. It’s a good idea to break the habit as early as possible, even if there are no issues.
