Insomnia, the inability to fall asleep or stay asleep, is a common sleep disorder. According to the American Sleep Association, about 30% of adults experience short-term insomnia, and 10% have chronic insomnia.

Insomnia affects people of all ages but is more common in older adults. Understanding the causes and symptoms of insomnia is essential in identifying and treating the condition.

What Causes Insomnia?

Insomnia can be caused by a variety of factors, including:.

1. Stress and Anxiety

Stress and anxiety are the most common causes of short-term insomnia. When people are worried, their minds tend to race, making it challenging to fall asleep.

While everyone experiences stress and anxiety from time to time, it’s when these feelings become chronic that it becomes a problem.

2. Lifestyle Factors

Lifestyle factors such as drinking too much caffeine, consuming alcohol, or eating a heavy meal close to bedtime can cause insomnia.

Sleep hygiene habits such as smoking, not exercising, or having an irregular sleep schedule can also make it challenging to fall asleep or stay asleep.

3. Medical Conditions

Several medical conditions can cause insomnia. These include chronic pain, arthritis, asthma, depression, and anxiety disorder.

Insomnia can also be a side effect of certain medications, such as antidepressants, steroids, and some allergy and cold medications.

Symptoms of Insomnia

The symptoms of insomnia vary depending on the type of insomnia one is experiencing. Short-term insomnia lasts for a few days to a few weeks and can be caused by stress or anxiety. Symptoms of short-term insomnia include:.

Difficulty falling asleep
Frequent wake-ups during the night
Waking up too early in the morning
Daytime sleepiness and fatigue
Irritability, mood swings, and difficulty concentrating

Chronic insomnia, which lasts for more than three months, can be caused by medical or psychiatric conditions. Symptoms of chronic insomnia include:.

Sleeplessness for an extended period
Frequent awakenings
Difficulty falling asleep after waking up in the middle of the night

Treatment Options for Insomnia

The most effective treatment for insomnia depends on the underlying cause of the condition. Behavioral therapy can be the first line of treatment for short-term insomnia. These include practices such as:.

Avoiding caffeine, alcohol, and nicotine a few hours before bedtime
Establishing a relaxing bedtime routine
Going to bed and waking up at the same time every day, even on weekends
Keeping the bedroom dark, quiet, and cool

If insomnia persists, a physician may prescribe medications to help the patient fall asleep or stay asleep. These medications must be taken under the supervision of a healthcare professional, as they can have adverse side effects.
