Causes and Symptoms of Insomnia
Insomnia is thought to be caused by a hyperarousal state that affects sleep onset and duration. Hyperarousal can be either mental or physical, or a mix of the two. Insomnia can be caused by a variety of reasons, including environmental, physiological, and psychological factors. The following are some of them:
- Disorders of the mind and behavior.
Insomnia is a typical depressive symptom. Insomnia can be caused by stress and worry, which can increase stressed and anxious sensations. Insomnia can also be caused by mental health issues such as bipolar illness. Insomnia is thought to be caused by excessive concern about sleepiness.
- Consumption or ingestion of drugs that have a bad impact on sleep.
Caffeine, as well as alcohol, nicotine, and other substances, are examples. Certain medications can also hinder sleep, such as diet pills and cold remedies. People may also have sleep-onset or sleep-maintenance troubles as their bodies adjust to new medications or deal with medication withdrawal after they’ve stopped taking them.
- Problems with your health.
Physical discomfort might make it more difficult to fall and/or stay asleep, resulting in daytime difficulties. Insomnia symptoms can also be caused by conditions that require numerous trips to the bathroom at night, such as pregnancy or an enlarged prostate. Sleep apnea, a disorder marked by irregular breathing episodes known as apneas that occur throughout the night, is the same. Insomnia is linked to chronic pain, restless limb syndrome, heart illness, and lung disease.
Circadian rhythms serve as an internal clock that regulates your sleep-wake cycle, metabolism, and body temperature. Insomnia can be caused by disrupting your body’s circadian rhythms. Jet lag from flying across numerous time zones, working a late or early shift, or changing shifts regularly are all causes.
- Excessive eating late at night.
It’s fine to have a modest snack before night, but eating too much can make the person physically uncomfortable when lying down. Heartburn, or a backflow of acid and food from the stomach into the esophagus after eating, is common and can keep the person awake.
