使用命令

tracker = HealthTracker()

# 记录饮水
tracker.log_water(250)  # 250ml

# 记录睡眠
tracker.log_sleep("23:00", "07:00")

# 记录步数
tracker.log_steps(8000)

# 获取统计
stats = tracker.get_stats()
print(f"今日饮水: {stats['water_today']}ml / {stats['water_goal']}ml")
print(f"平均睡眠: {stats['avg_sleep']:.1f}小时")

输出格式

## 健康数据

- 步数: 8000步
- 睡眠: 7.5小时 (平均)

### 周报
- 平均饮水: 1800ml/天
- 平均睡眠: 7.2小时/天
- 总步数: 56,000步
