Causes of Insomnia
For normal body functions, the recommended sleep per night should range between seven to nine hours. However, more than 50% of adults experience insomnia, a prevalent sleep disorder that can last for a few days or a prolonged period. People who have insomnia find it hard to fall asleep, stay asleep or sleep for the recommended hours. Also, individuals with a sleep disorder may exhibit other symptoms such as constant fatigue, memory loss, irritability, or depression.
Causes of Insomnia You Need To Know
Insomnia occurs in two major types: short-term insomnia and chronic insomnia. The former is mainly caused by stress and lasts for a few days or weeks, while major medical conditions may cause the latter, and the individual can take a longer period to recover.
What are the Causes of Insomnia?
Many factors can trigger insomnia, including environmental, physiological, and psychological factors. Some of the major causes of insomnia are:
Some drugs, such as Alpha-blockers and beta-blockers, have been linked with a sleep disorder. Alpha-blockers are known to decrease rapid eye movement, thus making people stay awake at night.
Beta-blockers cause insomnia by hindering the melatonin hormone’s nighttime secretion, responsible for regulating sleep and the body’s circadian clock.
Other medications that because insomnia includes corticosteroids, statins, SSRI antidepressants, ACE inhibitors, and others.
Also, sleeping pills can greatly cause insomnia since the body may become psychologically dependent on them for them to adjust. Before any drug usage, it is paramount to inquire from your pharmacist about medication usage and interactions.
The older you get, the more the chance of experiencing insomnia. Older adults have more irregular sleeping patterns as they tend to wake up earlier or get distractions during the night. Insomnia in older adults is common since an overwhelming majority of them have underlying medical conditions that cause pain or discomfort that interfere with their sleep.
Also, as you age, the secretion of growth hormones decreases, leading to a reduction in slow-wave or deep sleep. Thus, your body will produce less melatonin leading to increased fragmented sleep and frequent waking up during the night.
There is no way through which you can stop aging. If you are facing insomnia because of abnormal hormonal fluctuations in your body, through moderation of extreme hormonal changes, it is possible for you to get rid of this sleeping disorder. Just do some research about the symptoms associated with hormonal disbalance and opt for a credible hormone therapy thereafter.

Poor sleep hygiene habits can be a significant distraction to your sleeping patterns. The things you get involved with before bedtime can have a substantial effect on the quality of sleep.
Some of the bad sleep habits that can trigger insomnia include irregular bedtime schedules, eating right before getting to sleep, stimulating activities before sleep, taking coffee or alcohol, using technological devices in bed, or working out before bed. Make sure you avoid these habits in order to get a good night’s rest.

5. Stress and Anxiety
Stress occurs due to emotional or physical tension. Stress and anxiety affect the quality and quantity of sleep. Our bodies tend to keep us awake whenever we are stressed.
Stress triggers the secretion of cortisol hormone, which coincides with blood sugar, thus an upsurge in blood pressure. Due to this, your body experiences flight response, thus causing sleep problems.

Certain sleep disorders such as apnea can lead to breathing complications throughout the night, interfering with your sleep. Restless legs syndrome causes distressing sensations in your legs, making it difficult to move them, thus hindering you from falling asleep.

Pregnant women can experience insomnia in their entire pregnancy journey. Some of the factors that contribute to their sleep problems include:
- Discomfort: Pregnant women gain weight and develop changes in their entire body composition, thus affecting positioning and cause discomfort in bed.
- Breathing Interference: The developing uterus exerts pressure on the lungs disrupting breathing during sleep.
- Restless Leg Syndrome: Most pregnant women have increased potential of RSL even if they never portrayed similar symptoms before pregnancy.
