What Diseases Can Frequent Insomnia Cause? What Are the Consequences of Insomnia?

Insomnia is a common condition occurring across various age groups due to numerous factors. It affects health, mental well-being, and the ability to function and work effectively. So, what diseases can frequent insomnia cause, and what are the consequences of insomnia?

Nowadays, various factors, including aging, prolonged stress, unhealthy lifestyles, and other elements, are rapidly increasing the prevalence of insomnia, even among young people. This significantly impacts the lives of those affected. So, what diseases can insomnia cause, or what are the consequences of insomnia?

1. Memory and Concentration Impairment

One consequence of insomnia is its effect on the central nervous system (CNS). The CNS is the primary information pathway of your body. Sleep is essential for maintaining the normal function of the CNS, but chronic insomnia can disrupt how your body receives, processes, and transmits information.

During sleep, pathways form between neurons in the brain that help us retain new information. Lack of sleep can exhaust the brain, preventing it from performing its functions effectively.

You might also find it hard to concentrate or learn new things. The signals your body sends can be delayed, reducing coordination and increasing the risk of accidents.

Your mental health and emotional state can also be affected if you frequently experience sleep deprivation. You might experience mood swings, fatigue, and irritability. Decision-making, creativity, and task handling will also be impacted by prolonged insomnia.

In severe cases, you may begin to experience hallucinations, such as seeing or hearing things that don’t actually exist, if you suffer from prolonged insomnia. Sleep deprivation can also trigger mania in individuals with bipolar disorder.

2. Immune System Impairment

When asked about the consequences of frequent insomnia, immune system impairment is one of the key effects. During sleep, your immune system produces protective cells like antibodies and cytokines to combat infections. The system uses these immune cells to fight off invaders such as bacteria and viruses. Certain cytokines also help you sleep, enhancing the immune system’s effectiveness in protecting your body against illness.

Lack of sleep hinders the immune system’s ability to build up defenses. If you don’t get enough sleep, your ability to fend off pathogens weakens, making you more susceptible to illness. Additionally, you may take longer to recover after getting sick.

3. Respiratory Disorders

Sleep and respiratory disorders have a bidirectional relationship. Obstructive sleep apnea (OSA) can disrupt sleep and reduce sleep quality. This condition causes frequent awakenings during the night, leading to sleep deprivation and decreased sleep quality.

The consequences of insufficient sleep include a weakened immune system, making you more prone to respiratory infections such as the common cold and flu. Additionally, lack of sleep can exacerbate existing respiratory conditions, such as chronic lung diseases.

4. Overweight and Obesity

In addition to overeating and lack of regular exercise, insufficient sleep is another risk factor that contributes to overweight and obesity. Sleep affects the levels of two hormones, leptin and ghrelin, which help regulate hunger and fullness.

Leptin signals the brain that you have had enough to eat. When you don’t get enough sleep, your brain reduces leptin production and increases ghrelin production (which stimulates appetite). These hormonal changes can explain nighttime snacking or why someone might overeat late at night.

Lack of sleep can also leave you feeling low on energy, frequently fatigued, and unable to exercise. Weight gain can occur if physical activity decreases and food intake increases, as the body doesn’t burn enough calories and doesn’t build muscle mass. Insufficient sleep also leads to reduced insulin secretion after meals. Insulin helps lower blood sugar levels (glucose).

Insufficient sleep also decreases the body’s glucose tolerance and is associated with insulin resistance. These disruptions can lead to diabetes and obesity.

5. Cardiovascular Disease

Sleep affects blood sugar levels, blood pressure, and inflammation, all of which impact cardiovascular health. Sleep also plays a crucial role in the healing and recovery of blood vessels and the heart.

People who do not get enough sleep are at a higher risk of cardiovascular disease. Research has linked insomnia to an increased risk of heart attack and stroke.

6. Endocrine Disorders

Sleep quality is related to the body’s ability to produce hormones. To produce testosterone, you need at least 3 hours of uninterrupted sleep, which corresponds to the start of the first REM stage. Frequent awakenings throughout the night can disrupt hormone production.

This disruption can also affect growth hormone production, particularly in children and adolescents. These hormones help build muscle mass and repair cells and tissues, in addition to other growth functions. Growth hormone is released by the pituitary gland throughout the day, but sufficient sleep and exercise also help boost its release.
