Insomnia is a sleep disorder that makes it hard for people to fall asleep, stay asleep, or get restful sleep. It can lead to waking up too early and not being able to go back to sleep. This condition can be short-term (acute) or long-term (chronic), affecting a person's overall health and daily life.
Insomnia matters for health because it can cause fatigue, irritability, and difficulty concentrating. It can also affect mood and increase the risk of other health issues, such as anxiety and depression. When people do not get enough sleep, their immune system may weaken, making them more susceptible to illnesses.
In the body, sleep plays a crucial role in physical and mental health. During sleep, the body repairs tissues, produces hormones, and supports brain function. It helps with memory consolidation and learning. When sleep is disrupted, these functions can be impaired, leading to various health problems.
Overall, insomnia is a common issue that many people experience at some point in their lives. Understanding its impact on health can help individuals seek the support they need for better sleep quality.
