What might cause twitching legs while asleep?
Twitching legs during sleep can be caused by periodic leg movements or restless legs syndrome, which may be triggered by factors like medication or age.
Explanation
Twitching legs while asleep can be due to several reasons. One common cause is Periodic Leg Movements during Sleep (PLMS), especially in older adults. This involves repetitive leg movements that occur every 20 to 40 seconds during sleep.
Another cause is Restless Legs Syndrome (RLS), a condition where people feel an urge to move their legs, often accompanied by uncomfortable sensations. RLS can happen at night and disturb sleep.
Certain prescription medications can also cause or worsen restless legs syndrome, leading to more leg twitching at night.
If twitching legs are affecting sleep or daily life, it's important to talk to a healthcare provider. For more information on mental health, visit 988lifeline.org.
