11. Wellbeing: Sleep, Hydration & Movement | 身心健康：睡眠、饮水与运动

No revision plan works without a healthy brain. Aim for 7–9 hours of sleep each night, as the hippocampus consolidates learning during deep sleep. Drink water regularly to maintain concentration, and schedule a daily brisk walk or short workout. On Christmas Day and New Year’s Day, give yourself complete permission to rest and recharge – burnout serves nobody.

没有健康的大脑，任何复习计划都无从谈起。每晚保证 7–9 小时睡眠，因为海马体会在深度睡眠期间巩固学习内容。定时喝水以保持专注，并安排每日快走或短时间锻炼。在圣诞节和元旦，允许自己彻底休息和充电——过度疲劳对谁都没有好处。
