        How the seasons affect your sleep 季節如何影響你的睡眠

        季節會影響我們的睡眠嗎?根據最新研究,答案是肯定的。本期節目介紹我們的睡眠模式是如何演變而成的,以及光和溫度是否會對睡眠時間產生影響。

        詞匯:sleep 睡眠

        After a long winter, the arrival of spring can be a welcome relief. The days grow longer, the temperatures increase, and the natural world around us comes to life again. But when the seasons change, our sleep patterns change with them.

        New research suggests that humans may need more sleep in the winter than they do in the summer. A German study found that participants slept an hour longer in December than in June, regardless of their exposure to light. "Our study shows that even while living in an urban environment, with just artificial light, humans [experience] seasonal sleep," says Dieter Kunz, one of the study's lead authors and head of the clinic of sleep and chronomedicine at St Hedwig Hospital in Berlin, Germany. The study found that the participants experienced seasonal variations in their rapid eye movement sleep, also known as REM sleep, as well as in their slow wave sleep, also known as deep sleep. REM sleep, which is when we dream and our heart rate increases, was 30 minutes longer in the winter than during the summer. Slow wave sleep, which is when our muscles are repaired, our immune system is strengthened and our memory is consolidated, was 30 minutes shorter in September than in February.

        But why do our bodies and brains need more rest at certain times of year? The answer could lie in our evolutionary past. That's according to Neil Stanley, who's a sleep expert at Sleep Station, an online provider of cognitive behavioural therapy for insomnia. "We have evolved to dark-light cycles, so when we wake up on a winter's morning and it's dark, our brain is going 'I can't do anything… there's no point leaping out of bed.'" Particularly in summer, temperature also plays a role – our bodies require a skin temperature of between 31-35 degrees centigrade [Celsius] for a good night's sleep, but this can be harder to control during the warmer months.    

        Of course, nowadays, it is our school and work times – not the Sun – that determine when we get up in the morning. But, as autumn approaches, it seems we now have a good excuse for an early night.

        1. Is seasonal sleep affected by light?

        No. According to Dieter Kunz, "even while living in an urban environment, with just artificial light, humans [experience] seasonal sleep."

        2. True or False? Participants experienced seasonal variations only in REM sleep.

        False. Participants experienced seasonal variations in REM sleep, as well as in slow wave sleep.

        3. In total, how much longer do we need to sleep in winter compared to summer, according to the study?

        One hour. Both REM and slow wave sleep were 30 minutes longer in the winter months.

        4. How does our past influence our sleep patterns?

        Humans evolved to dark-light cycles, says Neil Stanley.

        5. Why can it be harder to sleep in the summer months?

        Because our bodies require a skin temperature of between 31-35 degrees centigrade [Celsius] for a good night's sleep, and this can be harder to regulate when it's hot.
