How decreasing sunlight in autumn affects sleep patterns

With seasonal transitions, shorter days and decreased sunlight directly affect the human body's sleep-wake cycle. Experts state that sleep disorders commonly seen during the autumn period should not be regarded as temporary fatigue.

Changes in the biological clock

The decrease in morning light during autumn months can alter the adaptation mechanism of the biological clock. This situation can manifest as difficulty waking up in the mornings, daytime sleepiness, and irregularity in sleep hours.

Symptoms and mental health

Persistent difficulty falling-asleep, waking up frequently at night, sleeping more than usual, and decreased concentration are among the most common symptoms. Long-term sleep disorders are closely related to depression and anxiety disorders.

Groups at risk

People with depression or bipolar disorder, shift workers, those who receive little natural light during the day, and those exposed to intense screen light in the evenings are in a much more sensitive position against seasonal changes.

Recommendations for sleep patterns

Moving during the day, going outdoors, and reducing screen use in the evenings improve sleep quality. In addition, limiting caffeine consumption in the afternoon and creating a suitable sleep environment are of great importance.
