How Can Excessive Light Exposure Cause Winter Fatigue?
Excessive light exposure can cause winter fatigue by disrupting sleep patterns, influencing mood, and leading to overstimulation of the eye and brain.
Disruption of sleep patterns: Bright light alters the body’s natural circadian rhythm, which regulates sleep-wake cycles. Research by Wright et al. (2013) indicates that exposure to intense light in the evening can delay the release of melatonin, the hormone responsible for sleepiness. This delay can result in shorter sleep duration and poorer sleep quality, causing fatigue during the day.
Influence on mood: Prolonged light exposure, especially blue light from screens, can affect serotonin levels in the brain. A study by Gooley et al. (2011) found that excessive light exposure can lead to a decrease in melatonin and altered serotonin production, which can contribute to mood swings and feelings of lethargy. Low mood can, in turn, exacerbate feelings of winter fatigue.
Overstimulation of the eye and brain: Excessive light can cause visual discomfort, leading to a condition known as digital eye strain. Symptoms of this strain include fatigue, headache, and blurred vision, as reported by Rosenfield (2016). Continuous exposure to bright lights, especially from screens, can lead to mental fatigue as the brain works harder to process visual information.
In summary, excessive light exposure can disrupt natural sleep patterns, affect mood regulation, and lead to eye and mental strain. All these factors can contribute to fatigue, especially during the winter months when shorter daylight hours are already present.
