Hypersomnia is a condition in which you feel excessive sleepiness during the day [2]. It may occur even after long stretches of sleep [1] and can be caused by medical conditions such as idiopathic hypersomnia, obstructive sleep apnea syndrome, narcolepsy or periodic limb movement disorder [4]. Symptoms include difficulty staying awake during the day, feeling tired despite sleeping for long periods of time, difficulty concentrating and memory problems [5]. Treatment options include lifestyle changes such as avoiding caffeine and alcohol before bedtime, taking short naps throughout the day and exercising regularly. Medications may also be prescribed to help with symptoms [3].

Hypersomnia is a sleep disorder characterized by excessive daytime sleepiness and long periods of nighttime sleep. People with hypersomnia may have difficulty staying awake during the day, even after getting enough hours of sleep at night. They may also experience fatigue, low energy levels, poor concentration, and memory problems. Treatment for hypersomnia typically involves lifestyle changes such as avoiding caffeine or alcohol before bedtime and establishing regular sleeping patterns. In some cases, medications such as stimulants can be used to help people stay awake during the day.
