Insomnia is more bound to happen as a result of aging. As people get older, changes in sleep patterns may occur. Sleep is often disturbed and restful as we age and with the internal clock advancing, people start feeling tired earlier than before. Additionally, there is the chronic pain of health issues that develop as a result of aging that creates insomnia. These include sleep apnea or restless legs syndrome.
These reasons can be split into a few groups: medical and psychiatric causes.
Medical causes of insomnia
There is a grand variety of medical conditions that can lead to insomnia. In some cases, there is one medical condition that can cause this disorder, but in others, the symptoms of it are the main reason for the sleeping difficulties.
The following medical conditions can cause insomnia:
- Gastrointestinal problems
- Nasal allergies
- Endocrine health problems
- Chronic pain
- Neurological conditions
- Back pain
Additionally, many of the medications commonly prescribed for the symptoms of these diseases can also cause insomnia. These include medications for common allergies, high blood pressure, thyroid disease, heart disease, asthma, birth control, and depression.
Another cause of insomnia is underlying sleep disorders such as restless leg syndrome. This is a neurological condition that occurs when people have the constant uncomfortable sensation of needing to move the legs. This syndrome worsens in later parts of the day due to inactivity in the transition to sleep. Therefore, this underlying symptom adds up to insomnia issues.
Another sleep disorder that can be linked to insomnia is sleep apnea. When one suffers from this disorder, the airway becomes obstructed during the sleep. This can lead to a drop in oxygen levels and trouble breathing. The person can wake up repeatedly throughout the night and have difficulties sleeping. People with this disease often experience insomnia because of their irregular sleeping habits.
Psychiatric insomnia causes
Insomnia can be caused by many psychiatric conditions, including depression. Psychological issues can make a person find difficulty in sleeping. Insomnia can also bring a shift in hormones and mood changes which only add to the psychological issues at the same time.
Sleep deprivation is a common depression symptom, so this psychological condition is often connected to the disorders. Studies show that insomnia can even worsen the depression symptoms.
Depression and insomnia are linked on many levels. Aside from their effect on each other, their symptoms are also interconnected. These include:
- Loss of interest
- Low energy
- Feeling of sadness
The good thing here is that both these conditions can be treated, regardless of which one caused the other one.
Another psychological condition linked to insomnia is anxiety. There are many people who have reported that anxiety is their main cause of insomnia. People often find it difficult to fall asleep because of worries, but some even see this as a pattern that ruins their sleep on a regular basis.
Anxiety can really add up to insomnia due to tension, excessive worrying, and feeling overwhelmed, revved up sensation and many other symptoms.
There are many mind-body and cognitive techniques that will aid people with troubles sleeping.
Insomnia is often perpetuated by an unhealthy lifestyle and sleeping habits. Lifestyle can create insomnia on its own or can add up to other medical or psychological conditions that cause it.
