Summer: Allow activity while protecting rest and fluids
Give flourishing a workable rhythm: movement, shade, ordinary fluids, meals, and recovery.

使志无怒，使华英成秀。
Editorial translation
Keep intention free of anger; let flowering come to fullness.
Meaning in context. The summer passage describes flourishing and outward expression. Its seasonal imagery offers a disposition, not a requirement to be endlessly active.
Application today. Use cooler settings for activity when hot, and keep space for meals, rest, and social contact that suits you.
Reading limit
Do not read the chapter’s sun-related language as advice to ignore modern heat and UV precautions.
Classical reasoning · 夏 · 长
The summer chapter describes flourishing, emotional openness, and activity within a longer day. The spring–summer emphasis on nourishing yang does not mean deliberately overheating the body.
Sleep and waking · 起居
Maintain sufficient sleep even when daylight lasts longer. Keep the sleeping space comfortable and avoid using late evenings to accumulate sleep debt.
Measured movement · 运动
In hot weather, choose cooler hours or a suitable indoor space, reduce intensity when necessary, and pause rather than push through heat-related dizziness.
Food and fluids · 饮食
Keep meals regular and varied, and have drinking water available. Follow any prescribed fluid restriction; do not replace meals with juices or herbal drinks.
Mind and emotions · 调神
Enjoy company if it suits you, with quiet intervals. A busy social calendar is optional, not an obligation to match the season.
Avoid the common shortcut
More sweat is not a better workout and is not proof of detoxification. Do not use moxibustion or heating products merely because the season is associated with yang.
