C1-45 Reading Comprehension

Sleep is a fundamental biological need that affects nearly every aspect of health and well-being. During sleep, the body repairs tissues, consolidates memories, and regulates hormones. Lack of sleep can impair cognitive function, weaken the immune system, and increase the risk of chronic diseases such as diabetes and heart disease.

和訳

睡眠は健康や幸福のほぼすべてに関わる基本的な生理的ニーズです。眠っている間に体は組織を修復し、記憶を定着させ、ホルモンを調整します。睡眠不足は認知機能の低下や免疫力の低下、糖尿病や心臓病など慢性疾患のリスク増加をもたらします。

Sleep quality is just as important as quantity. Factors such as stress, screen time before bed, and irregular sleep schedules can disrupt the sleep cycle. Good sleep hygiene—like maintaining a consistent bedtime routine and creating a comfortable sleep environment—can help improve both the duration and quality of rest.

和訳

睡眠時間だけでなく、質も重要です。ストレスや寝る前の画面使用、不規則な睡眠リズムなどが、睡眠サイクルを乱す要因となります。毎晩決まった習慣を守る、快適な寝室環境を作るなどの「良い睡眠習慣」は、睡眠の長さと質の両方を高めてくれます。

Chronic sleep deprivation can also affect mood, increasing the likelihood of anxiety and depression. Conversely, getting enough restful sleep boosts concentration, creativity, and emotional resilience, making it easier to handle life’s challenges.

和訳

慢性的な睡眠不足は気分にも影響し、不安やうつのリスクを高めます。逆に、十分で質の良い睡眠は集中力や創造性、感情の回復力を高め、日々の困難にも前向きに対処できるようになります。

Prioritizing sleep is one of the most effective steps individuals can take to support their physical and mental health, productivity, and overall quality of life.

和訳

睡眠を大切にすることは、健康・生産性・人生の質を高めるために誰もができる最も効果的な方法の一つです。
