Lead author Dr Monique LeBourgeois, from the University of Colorado at 玉石, said: 'Light is our brain clock's 最初の／主要な timekeeper. We know younger individuals have larger pupils, and their レンズs are more transparent, so their （危険などに）さらす and sensitivity to that light is even greater than in older individuals.'
