不吃早餐和熬夜的危害（演讲稿）
经常不吃早饭，会得胃病，你现在还年轻，不吃早饭胃不会疼，将来年龄大了，就会知道不吃早饭的严重后果了熬夜会导致内分你失调，皮肤变差，甚至死亡危险率上升。
缺觉、睡多了，其实对身体都不好。
睡眠时间在6.5小时-7.5小时之间，死亡率最低，少于6.5小时或者高于7.5小时之后，死亡危险率都大大增高，尤其是睡眠时间超过9.5小时或少于4.5小时，死亡危险率直接翻倍。

如何总结一下关于熬夜的班会演讲
（急用）
1\\\/4 精力： 一通宵醒着的精力损失大概相当于连续登山一上午。
由此带来的外症有：头晕眼花，耳鸣，四肢乏力及注意力和思考能力严重下降。
如果长期熬夜，更会慢慢地出现失眠、健忘、易怒、焦虑不安等神经、精神症状。
过度劳累使身体的神经系统功能紊乱。
皮肤： 女同志需特别注意。
一般来说，油性皮肤抗老化能力比较强。
不规律的睡眠及压力，会影响内分泌代谢不完全，造成皮肤水分流失，容易导致皱纹出现、皮肤暗淡、长暗疮、黑眼圈加重等，尤其是上完妆后情况会更糟，妆很难化均匀。
2\\\/4消化系统：晚上9-11点为免疫系统（淋巴）排毒时间，此段时间应安静或听音乐 。
晚间11-凌晨1点，肝的排毒，需在熟睡中进行。
凌晨1-3点，胆的排毒，亦同。
凌晨3-5点，肺的排毒。
此即为何咳嗽的人在这段时间咳得最剧烈，因排毒动作已走到肺；不应用止咳药，以免抑制废积物的排除。
半夜至凌晨4点为脊椎造血时段，必须熟睡，不宜熬夜。
3\\\/4熬夜时人处于紧张状态，得不到放松，造成血管收缩异常，血压比正常人高，容易诱发高血压或者加重病情。
现在心脑血管疾病发病率逐渐增多且越来越年轻化，常熬夜或是诱因之一。
4\\\/4熬夜伤身也伤神，许多年轻人晚上不睡，白天发困，出现神经衰弱等问题，严重的甚至会导致抑郁症的发生。
