Insomnia is an extremely distressing condition, yet it plagues many people. The cycle of sleepless nights and daytime fatigue is a common reality in modern society. Insomnia has its causes, and only by identifying them can it be thoroughly addressed. Below, we explore the five major factors contributing to insomnia.
1. Medical Conditions
Physical illnesses linked to insomnia include heart disease, kidney disease, asthma, peptic ulcers, arthritis, osteoarthritis, gastrointestinal disorders, hypertension, sleep apnea syndrome, hyperthyroidism, nocturnal myoclonus syndrome, and neurological diseases.
2. Physiological Factors
Environmental changes trigger physiological responses, such as altered sleep conditions during travel by car, ship, or plane. Bright lights, noise, extreme temperatures, or poor ventilation in the bedroom can also disrupt sleep. Some individuals adapt well to environmental shifts, while others are highly sensitive and struggle to adjust, leading to poor sleep quality when surroundings change.
3. Psychological Factors
Psychological causes: Anxiety, restlessness, low mood, or unpleasant emotions are significant contributors to insomnia. Life setbacks, work/study pressures, unfulfilled desires, and social changes can trigger psychological and physiological responses, disrupting nervous system function and causing brain dysfunction that leads to sleep disturbances.
4. Medication Factors
Central nervous system stimulants can cause insomnia. Additionally, long-term use of sleeping pills may lead to withdrawal symptoms—shallow sleep and frequent nightmares—upon discontinuation.Alcohol disrupts sleep architecture, making sleep lighter. Quitting alcohol can also cause insomnia due to withdrawal reactions.
Friendly Reminder: We hope this overview of the five major causes of insomnia proves helpful. Once you identify the cause, actively work to improve it. Otherwise, prolonged insomnia can easily lead to mental breakdown.
