集中注意力的秘訣

Sleep More

睡眠充足

Studies show that people who sleep fewer than eight hours a night for a prolonged period of time have slower response systems andmore difficulty recalling information. In fact, even minor restrictions in yoursleep patterns can affect your academic performance in a bad way.

研究表明長期處于睡眠時間少于8小時的人反應較遲鈍，記憶力也會受損。實際上，即使是少睡一點點也能給你的學術表現帶來負面影響。

Eat Healthier Foods

健康飲食

Foods that are high in fat and sugar might give youa temporary burst of energy, but that energy is soon followed by a crash. Onceyour body burns up the rush of nutrient-deprived, over-processed foods, you will start to feel groggy and lethargic.

高脂高糖的食物可能可以暫時讓你補充大量能量，但是這些能量會很快被消耗完。一旦你的身體消化了這些沒營養的過度加工食物，你就會昏昏欲睡。

【知識點講解】
