A growing body of research now points to a troubling reality for millions worldwide: exposure to artificial light after dark—whether from smartphones, bright hospital lamps, or night shifts—may be fundamentally rewiring the human brain, with ripple effects throughout the body. New findings highlight the health risks tied to Thailand’s own rapidly urbanizing, brightly lit environment, raising concerns for workers and families across the nation.

Rapid urbanization in Thailand has brought the glow of artificial light to every corner, from Bangkok’s neon-lit streets to rural provinces seeing a surge in 24-hour service culture. While most Thais associate bright lighting with modern comfort and safety, scientists are finding that our brains remain hardwired for ancient, natural cycles of light and darkness—a system increasingly disrupted by modern habits. According to recent research by leading neuroscientists at West Virginia University, the effects extend well beyond sleeplessness: chronic exposure to artificial light at night has been shown to disturb our body’s master clock, or circadian rhythm, which in turn can weaken the immune system, increase inflammation, change appetite-regulating hormones, and disrupt mood.

New research shows that exposure to artificial light after dark can disrupt the body’s natural rhythms, affecting sleep, metabolism, mood, and immune function. In Thailand’s fast-urbanizing landscape, bright night lighting is common in homes, workplaces, and public spaces, making these findings highly relevant for Thai health.

Urban growth has brought constant illumination from Bangkok’s neon streets to smaller cities embracing 24-hour services. Although bright lighting is convenient, experts warn that the body still responds to circadian cues. Researchers explain that chronic nighttime light can disturb the circadian rhythm, potentially weakening immunity, triggering inflammation, altering hunger hormones, and influencing mood.

Artificial lighting shapes daily life across Thailand, from bustling Bangkok streets to quiet rural towns. New findings from a leading U.S. neuroscience center show that nighttime light exposure can alter the brain, affecting immune function, metabolism, mood, and even the reliability of scientific results.

Long-term studies indicate that light at night disrupts the body’s master clock. These circadian changes can trigger neuroinflammation, mood fluctuations, and metabolic issues such as diabetes. The research matters for Thai workers who perform night shifts, residents in neon-lit urban areas, and anyone relying on screens after dark.

In Thailand’s bustling cities and illuminated rural corners, the glow of artificial light around the clock has become an inseparable part of daily life—sometimes at the expense of our own biology. New research led by a senior neuroscientist in the United States underscores the profound impact of nighttime artificial light on the human brain, linking modern lighting habits to disruptions in immune function, metabolism, mood, and even the accuracy of scientific studies themselves (StudyFinds).
