Stress is a normal part of our lives, and some stress is actually good for you. Studies on rats performed by the University of California Berkeley found that brief periods of stress improved their mental performance after a couple of weeks (via Berkeley News). "You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley. "Some amounts of stress are good to push you just to the level of optimal alertness, behavioral and cognitive performance."

压力是我们生活中正常的一部分，有些压力实际上对你有好处。加州大学伯克利分校对老鼠进行的研究发现，短时间的压力在两周后改善了他们的精神表现(见伯克利新闻)。“你总是认为压力是一件很糟糕的事情，但事实并非如此，”伯克利加利福尼亚大学的综合生物学副教授Daniela Kaufer说。“一定程度的压力有助于将你推向最佳警觉性、行为和认知水平。”

But while short bursts of stress may be helpful to the brain, chronic stress is not. Ongoing stress can cause many health problems, one of which is bruxism. Bruxism refers to teeth grinding and jaw clenching that is often associated with stress and anxiety (via National Health Service). Side effects of bruxism include headaches, facial pain, and disrupted sleep. It can also cause you to wear down and break your teeth if it goes on long enough without treatment. Stress can also weaken your immune system, which can contribute to other dental problems like gum disease (via Live Science). However, according to Live Science, it is unlikely that stress alone could cause your teeth to fall out. Such a severe outcome in your dental health is more likely to be caused by serious gum disease left untreated for a long period of time.

但是，虽然短暂的压力爆发可能有助于大脑，但慢性压力却不是。持续的压力会导致许多健康问题，其中之一就是磨牙症。磨牙症是指磨牙和咬紧牙关，通常与压力和焦虑有关。磨牙症的副作用包括头痛、面部疼痛和睡眠中断。如果长时间不治疗，也会导致你的牙齿磨损和折断。压力也会削弱你的免疫系统，从而导致其他牙齿问题，如牙龈疾病(通过生命科学)。然而，据《生命科学》报道，压力本身不太可能导致牙齿脱落。如此严重的牙齿健康后果更有可能是由于长期未经治疗的严重牙龈疾病造成的。

Although stress may not cause your teeth to fall out, it comes with plenty of other negative side effects that you want to avoid. According to Cleveland Clinic, physical symptoms of stress include aches and pains, increase heart rate, fatigue, dizziness, and high blood pressure. You can also experience stomach problems, a weakened immune system, and sexual dysfunction. Emotional and mental symptoms of stress include anxiety, irritability, depression, panic attacks, and sadness.

虽然压力可能不会导致你的牙齿脱落，但它也会带来很多你想要避免的负面影响。根据克利夫兰诊所，压力的身体症状包括疼痛、心率加快、疲劳、头晕和高血压。你还可能经历胃部问题、免疫系统减弱和性功能障碍。压力的情绪和精神症状包括焦虑、易怒、抑郁、恐慌和悲伤。

Chronic stress even has behavioral symptoms, which can include changes in appetite, avoiding responsibilities, and increased nervous behaviors like nail-biting and fidgeting. People who are chronically stressed may try to manage their emotions in unhealthy ways like overusing drugs and alcohol to reduce their stress levels.

慢性压力甚至有行为症状，包括食欲的变化、逃避责任、咬指甲和坐立不安等神经行为的增加。长期有压力的人可能会试图用不健康的方式来控制自己的情绪，比如滥用药物和酒精来减轻压力。

Fortunately, there are many ways to manage your stress levels. Exercising regularly can help, as well as relaxing practices like meditation and yoga. If you feel like you can't manage your stress, speak with your healthcare provider. Sometimes therapy or medications are the best way to deal with chronic stress.

幸运的是，有很多方法来管理你的压力水平。定期锻炼和放松练习，比如冥想和瑜伽，都会有所帮助。如果你觉得你不能控制你的压力，和你的医疗服务人员谈谈。有时治疗或药物是对付慢性压力的最好方法。
