Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or experiencing poor-quality sleep. As a result, people with insomnia may experience daytime fatigue, low energy levels, mood disturbances, and difficulties with concentration and memory.
Insomnia can be classified into two main types: primary and secondary.
Primary insomnia refers to sleep problems not directly caused by another underlying condition or medical issue. It is often related to stress, anxiety, depression, lifestyle choices, or poor sleep habits. Secondary insomnia, on the other hand, is caused by an underlying medical, psychiatric, or environmental condition. It can be associated with chronic pain, respiratory disorders, gastrointestinal problems, hormonal imbalances, medication side effects, substance abuse, or sleep conditions like sleep apnea.
Some common signs or symptoms that may indicate you have insomnia:
- Difficulty falling asleep at night
- Trouble staying asleep, waking up frequently during the night
- Waking up too early in the morning and struggling to go back to sleep
- Feeling tired or not refreshed upon waking up
- Daytime fatigue, sleepiness, or low energy levels
- Difficulty concentrating or focusing on tasks
- Mood disturbances, such as irritability, anxiety, or depression
- Increased errors or accidents due to lack of concentration
- Hyperarousal or heightened awareness at night, making it hard to relax and fall asleep
- Overthinking or racing thoughts that prevent you from falling asleep
- Dependence on sleep aids or medications to fall asleep
- Chronic worry or anticipation of sleep problems
- Impaired performance at work, school, or daily activities due to lack of sleep
- Inability to nap or take daytime restorative sleep
- Increased reliance on certain stimulants to stay awake during the day
It’s important to note that experiencing occasional sleep difficulties or a few of these signs does not necessarily mean you have insomnia. However, if you consistently experience these symptoms and they interfere with your daily functioning or quality of life, it is advisable to consult with a healthcare professional for a proper diagnosis and guidance.
