A Comprehensive Guide to Solving Insomnia: From Melatonin to Lifestyle Adjustments

Insomnia is a prevalent issue in contemporary society, affecting not only nighttime rest but also daytime vitality and long-term health. Understanding the causes of insomnia and its solutions is crucial for improving quality of life. This article will explore the main causes of insomnia, the role of melatonin, and effective strategies for resolution.

Main Causes of Insomnia

  • Psychological Stress: The fast pace and high pressure of modern life are leading causes of insomnia. Work stress, financial issues, and interpersonal conflicts can all increase psychological stress, thereby affecting nighttime rest.
  • Poor Lifestyle Habits: Beyond stress, unhealthy lifestyle choices such as consuming caffeine and alcohol at night, irregular sleep patterns, and excessive use of electronic devices before bed can disrupt normal sleep.
  • Physical Health Issues: Conditions causing discomfort, such as pain, heart disease, asthma, and acid reflux.
  • Environmental Factors: Noise, insufficient darkness, and uncomfortable temperatures can also lead to difficulty falling asleep.


Among these insomnia culprits, half are related to external environments and diseases, which have short-term impacts and clear solutions. However, the remaining causes are hidden beneath the surface, not easily detected without sufficient understanding. It’s essential to comprehend the physiological mechanisms that have governed our sleep patterns for millennia and how modern environmental changes have led to unprecedented insomnia issues.

Melatonin and the Sleep Cycle

Melatonin is a key hormone secreted by the pineal gland in the brain that regulates the sleep-wake cycle. As night falls, melatonin levels rise, helping the body enter a state of rest; exposure to sunlight in the morning decreases its secretion, activating an alert state. Surrounded by artificial light sources in modern life, especially the blue light emitted by electronic devices, has the same effect of inhibiting melatonin secretion. Excessive or late-night use of electronic devices can impact sleep quality.

Solutions for Insomnia

  • Regular Sleep Routine: Establishing fixed sleep and wake times, even on weekends, helps regulate the biological clock.
  • Improving the Sleep Environment: Creating a quiet, dark, and cool sleeping space, and choosing suitable mattresses and pillows, can foster a comfortable sleep environment.
  • Reducing Stimulants: Avoiding caffeine and alcohol at night minimizes sleep disturbances.
  • Limiting Electronics or Reducing Blue Light Exposure: Decreasing electronic device use before bed or applying blue light filters can lessen the impact on melatonin secretion.
  • Learning Relaxation Techniques: Employing deep breathing, meditation, yoga, and other methods can ease stress and promote sleep. Additionally, certain acupressure techniques are believed to help alleviate insomnia.

Long-term Insomnia Treatment

For those suffering from chronic insomnia, seeking medical assistance to understand underlying health issues is recommended. Professional sleep therapy, including cognitive-behavioral therapy, can offer targeted solutions.


Insomnia is a complex issue caused by multiple factors, necessitating improvements in lifestyle, mental health, and physical environment. Understanding the role of melatonin in sleep regulation and the impact of modern environments on this mechanism is vital for devising effective solutions. By implementing the suggestions above, improving sleep quality and enjoying life with ample energy is achievable.
