用脑过度

孩子用脑过度有害无益,家长应该怎么应对

现在小学生每天早上7点出门上学,晚上五六点钟才能回家,然后做作业复习功课一直到晚上九十点钟。有的家长每逢周六、周日还给孩子报各种辅导班,使得孩子每天的“工作量”不亚于成年人。

学习消耗的主要是脑力,长期集中精神思考、学习,使大脑长期兴奋过度,脑细胞的功能就会发生改变,受到影响。过度用脑,还会导致头昏眼花、记忆力下降,影响孩子的注意力、学习能力、学习效率,使孩子觉得疲倦,对学习失去兴趣,有的人甚至会对上学产生恐惧情绪。

所以一定要让孩子的学习生活有张有弛,科学用脑,否则会得不偿失。有的家长为了让孩子专心学习,什么家务活也不让他们干,其实,这样做恰恰让孩子失去了一个很好的锻炼协调能力的机会。

另外保证孩子的睡眠也很重要。孩子的大脑皮层一般会在晚上10时后开始分泌生长激素,这是孩子睡眠的最佳时机,每天应让孩子有9-10小时的睡眠。同时,午睡也不可缺少,他们的大脑经过了一个上午的学习思考,应该有一个小小的休息时间。

另外小编为大家推荐4种超补脑的食品,提高脑活力。经常熬夜加班的白领也可以多吃以下这些食物,缓解脑力疲劳。

补脑食物1、鱼

鱼类所含的DHA是补脑的关键元素。DHA,有“脑黄金”的称号,它们在人体内主要是存在脑部、视网膜和神经中。DHA可维持视网膜正常功能,婴儿尤其需要此种养份,促进视力健全发展;DHA也对人脑发育及智能发展有极大的助益,亦是神经系统成长不可或缺的养份。鱼肉还是优质蛋白质和钙质的极佳来源,特别是含有大量的不饱和脂肪酸,对大脑和眼睛的正常发育尤为重要。

根王深海鱼油选自新西兰优质深海小鱼,小型鱼类的生命周期短暂,能够避免吸收更多潜在于海洋的环境毒素及重金属的富集。每粒含有丰富的EPA和DHA,而且清新薄荷无腥味,深受小朋友的喜爱。

补脑食物2、核桃

核桃是食疗、补脑佳品,被公认为中国传统的健脑益智食品,孩子们一定要食用喔。核桃中的磷脂,对脑神经有良好保健作用。核桃油含有不饱和脂肪酸,有防治动脉硬化的功效。核桃仁中含有锌、锰、铬等人体不可缺少的微量元素。每日2-3个核桃为宜,持之以恒,方可起到营养大脑、增强记忆、消除脑疲劳等作用。

根王补脑素使用新鲜纯正成熟长寿果(核桃),经科学工艺技术压榨而成的核桃油为主要原料。富含天然亚麻酸、亚油酸、VA、VD等营养物质。营养丰富, 口感清淡无异味,脂肪酸组态近似母乳,易被消化吸收,是儿童发育期的高级保健食用油,可以提高记忆力,改善视力,增强免疫力。

补脑食物3、花生

花生是大众喜欢的传统食品,有一定的药用价值和保健功能,其中含有7%多酚物质,多酚物质的抗氧化性是维生素E的50倍,可有效延缓衰老、增进智力,被古人称为“人参果”,是世界公认的三大益智健脑坚果之一。花生富含卵磷脂和脑磷脂,它是神经系统所需要的重要物质,能延缓脑功能衰退,抑制血小板凝集,防止脑血栓形成。实验证实,常食花生可改善血液循环、增强记忆、延缓衰老,是名符其实的“长生果”。

花生富含泛酸可提高记忆力。泛酸(维生素B5),搭配蛋黄、大豆所含的卵磷脂一同摄取,能提高记忆力。牡蛎、动物肝富含的尼克酸(维生素B3)也有改善记忆力的作用。富含泛酸的食材有酵母、花生、豆腐、大葱、韭菜、西兰花等。

补脑食物4、猕猴桃

世界上消费量最大的前26种水果中,猕猴桃最为丰富全面。猕猴桃果实中的vc、mg及微量元素含量最高,并且是维持心血管健康的重要营养成分。在前三位低钠高钾水果中,猕猴桃由于较香焦及柑桔含有更多的钾而位居榜首。

猕猴桃富含维生素C缓解抑郁。维生素C在脑内神经递质合成过程中也发挥作用,可缓和抑郁症。富含维生素C的食材有柑橘类、草莓、猕猴桃、番石榴、苦瓜、鲜枣等。牛奶是优质蛋白质、核黄素、钾、钙、磷、维生素B12、维生素D的极佳来源,这些营养素可为大脑提供所需的多种营养。

宝妈们平时就多给孩子吃这些食物吧,还有就是让孩子们劳逸结合哦!

Tongkat Ali is known to boost performance, stamina, and muscle mass in bodybuilding. In a clinical study conducted with a group of men, half the male was given Tongkat Ali to consume while the other half were not. During a few weeks of the physical training program, the men who consume the herbs experienced greater muscle mass gain, stamina, and strength. There were also a growing number of Asian athletes and bodybuilders whom are using Tongkat Ali as an androgen booster to improve muscle size and enhance their sports performance.

Testosterone is a male hormone that can be found in both men and women. But it is more of the male characteristics. Usually, at age 30, blood levels of testosterone start to decline slowly. If testosterone declines in a man’s body, his muscles, energy, and libido begin to decrease. Men who smoke and drink alcohol excessively lose testosterone faster than those who don’t. Male hormones or testosterone stimulates metabolism, promotes fat burning, increases red blood cells and muscle growth.
