让健身成为一种生活方式
“健康中国”战略 Healthy China Strategy
National fitness is a foundation and a guarantee for all people to fortify their bodies and live a healthy life.Nowadays,people’s growing awareness of their own health and attention to leading healthy lives enable them to do fitness voluntarily and scientifically.People’s attention to health not only serves as an inevitable outcome of rising living standards,but also reflects their aspirations for the pursuit of a better life.We should run national fitness campaigns,continuously upgrade the facilities
for mass fitness,and further develop people’s cultural and sporting lives in order to better meet people’s demands for fitness and pique people’s passion for fitness.
Let us all be part of a healthy China.To keep healthy and exercise scientifically is not only responsible for oneself,but also for the family,the society and the country.The responsibility of health should be placed on everyone, the task of fitness should be put into practice every day,and fitness should become a way of life.By persevering,we will have a stronger body and a fuller spirit,and the construction of a healthy China will have stronger support.
人们的睡眠模式在青少年时期会发生变化。许多青少年从早起的“百灵鸟”变成了“夜猫子”。他们感觉在晚上更有效率,警觉性更高,但睡得更晚,第二天醒得也更晚。
研究发现,在青春期早期(大约12一13岁)转变为“夜猎子的青少年更有可能在几年后出现行为问题,包括更大的攻击性、违反规则和反社会行为,但他们发生情绪问题的风险并没有增加,比如焦虑或情绪低落。
新研究还表明,早起的“百灵鸟”和晚睡的“夜猫子”的大脑结构和发育速度不同,包括灰质和白质的差异,这与记忆、情绪健康、注意力和同理心的差异有关。“夜猫子”青少年的脑白质没有增加到与早起的青少年相同的程度。事实上,在青少年时期,脑白质的发育对于支持认知、情感和行为的发展非常重要。(306字)
焦虑或情绪低落 anxiety or depression
People’s sleep patterns will shift during adolescence.A lot of teenagers have transformed from “larks”,-who get up early to work or study,-to “night owls”,-who stay up very late at night,-because they feel more productive and aware at night,which makes them go to bed very late and wake up very late the next day.
A study found that those adolescents who has become “night owls”in early adolescence (between the ages of 12 and 13)were more likely to experience behavioral issues later on,such as increased aggression,rule-breaking,and antisocial behavior,but they were not more likely to experience emotional issues like anxiety or depression.
According to recent studies,the brains of”larks”and “night owls”have different structures and speeds of growth,including variations in the amount of gray and white matter,which are associated with variations in memory,emotional well-being,attention and empathy.The amount of white matter in the brain of those teenagers who sleep very late at night hasn’t been increased to the same amount as that of those teenagers who get up early in the morning.In reality,in adolescence,the growth of white matter in one’s brain is of great significance to the development of cognition,emotion and behaviors.
