Sleep disturbance refers to any disruption or alteration in the normal sleep pattern, duration, or quality that leads to difficulties falling asleep, staying asleep, or experiencing restorative sleep. Common types of sleep disturbances include insomnia, characterized by difficulty falling or staying asleep; sleep apnea, where breathing interruptions occur during sleep; restless leg syndrome, causing uncomfortable sensations in the legs; and sleepwalking or night terrors. Sleep disturbances can result from various factors, including stress, medical conditions, medications, lifestyle choices, or mental health disorders. Proper diagnosis and treatment are essential to address sleep disturbances and prevent associated negative impacts on physical and mental well-being.
