现代社会的生活节奏较为紧张，造成疲劳的原因也较为复杂。专家们把疲劳划分为四类：
一、体力疲劳。
这是由于过份劳累—血液中二氧化碳和乳酸增多—导致的肌肉疲劳，表现为四肢乏力、肌肉酸疼，但精神上毫无痛苦，甚至还有几分惬意。
消除体力疲劳的最佳方法是睡眠，临睡前洗个热水澡或用温水泡泡脚，会使疲劳消除得快一些。在睡眠时，全身物质代谢降低，神经细胞可借机吸收各种营养物质，为苏醒后神经活动准备充足的能量。充足的睡眠可使人迅速消除疲劳，保持充沛的精力。合理的饮食能补充体力劳动消耗的大量营养物质，所以也是消除疲劳的必要措施。
二、脑力疲劳。
是指长时间用脑，引起脑的血液和氧气供应不足，而出现大脑疲劳感。其主要表现为头昏脑胀，食欲不振，记忆力下降，注意力不集中等。
消除脑力疲劳的主要方法是适当参加体育活动。这也是被称为积极地休息。可打打球、做做操、散散步，但锻炼的强度不宜大，时间不宜过长。
三、病理疲劳。
这种疲劳有时并不需付多大的体力就产生，有一种心力不足的虚弱感。这是由于你体内的某些“机器”发生故障，产生代谢与分泌紊乱、失调所致。
要消除这种疲劳，关键是治好疾病。有些人虽未发现局部器官病痛症状，却经常出现疲劳的话，就有可能是病症即将出现的先兆，需到医院认真地检查。
四、精神疲劳。
这是现代社会疲劳症中最复杂的一种疲劳。最主要是长期超负荷运行形成慢性疲劳，精神压力过大也是重要原因。不幸的是，这种疲劳往往被人忽视。精神疲劳最明显的表现莫过于失眠。做不连贯的梦，在噩梦中惊醒，辗转不眠甚至彻夜不眠等等。
一般人喜欢用安眠药对付这些问题，其实这并不是根本的解决办法。专家们认为下列几种方法对消除精神疲劳极为有效。
(1)首先应讲究心理卫生、加强品德修养，自己的心胸要开阔，以减少心理疲劳的发生。一旦出现，应及时宣泄自己的不良情绪，不要闷在心里，比如找知心朋友谈谈心。
(2)进餐时间规律化。有规律地进餐，可以使身体经常处于正常的新陈代谢状态。
(3)多锻炼。身体健康的人可以进行一些体育活动，譬如慢跑、骑自行车、游泳、散步等等。锻炼可以使人工作起来更自信，碰到困难时更加从容不迫。黄昏时活动活动身体还可以使你更好地进入梦乡。
(4)多睡觉。精神疲劳的一个重要原因是睡眠不足。有这种情况的人每天应当多增加一个小时的睡眠。每个人的睡眠需要是不同的，应该找出最适合于自己的睡眠固定时间。
(5)把握精力高峰期。有些人上午生气勃勃，有些人晚间精力充沛，找出自己的精力高峰期极为重要，这样可以恰当地安排好自己的作息时间。
