As the days grow shorter and colder, many people notice a stronger urge to sleep longer and more deeply. This is not just a matter of feeling lazy or unmotivated. Instead, it reflects a natural biological response to seasonal changes in daylight.
During winter, reduced sunlight increases melatonin production, which influences our circadian rhythms and leads to longer, deeper REM sleep.
This phenomenon, sometimes called "winter hibernation," is a gentle adjustment rather than true hibernation. Many individuals find themselves sleeping an extra one to two hours each night, which supports better rest and mood.
Sleep is not just a passive state but a vital process that supports every aspect of health. Winter sleep patterns reflect our body's wisdom in adapting to seasonal changes. By understanding and respecting these natural rhythms, we can improve our rest, mood, and overall well-being.
