      <abstract xml:lang="en">
        <p>This study explores why students feel tired even after getting enough sleep. The research was conducted with 20 students using a questionnaire and one-week screen time observation. The results show that phone use, stress, and overthinking are the main causes of fatigue rather than lack of sleep. These findings suggest that improving sleep habits and reducing screen time can help increase students‘ energy and academic performance.</p>

        <p>Данное исследование изучает причины, по которым студенты чувствуют усталость даже после достаточного сна. Исследование было проведено среди 20 студентов с использованием анкеты и недельного наблюдения за временем использования экранов. Результаты показали, что основными причинами усталости являются использование телефона, стресс и чрезмерные размышления, а не недостаток сна. Полученные данные свидетельствуют о том, что улучшение привычек сна и сокращение времени использования экранов могут помочь повысить уровень энергии студентов и их академическую успеваемость.</p>

        <p>Ushbu tadqiqot talabalar nima sababdan yetarli uyqu olganidan keyin ham charchoq his qilishini o‘rganadi. Tadqiqot 20 nafar talaba ishtirokida so‘rovnoma hamda bir haftalik ekran vaqti kuzatuvi orqali olib borildi. Natijalar shuni ko‘rsatdiki, charchoqning asosiy sabablari uyqu yetishmasligidan ko‘ra telefon ishlatish, stress va ortiqcha o‘ylash bilan bog‘liqdir. Ushbu natijalar uyqu odatlarini yaxshilash va ekran vaqtini kamaytirish talabalarning energiya darajasi hamda akademik samaradorligini oshirishga yordam berishini ko‘rsatadi.</p>
