为什么要每天定期洗澡?
One study from Osaka, Japan found that daily bathers were less likely to have a heart attack or stroke than those who showered 1-2 times per week, or did not shower at all.
日本大阪的一项研究发现，每天洗澡的人患心脏病或中风的几率比那些每周洗澡1-2次或根本不洗澡的人要低。
Following healthy study participants for about 19 consecutive years, starting in 1990 between the ages of 45-59 until the end of 2009, researchers found that daily bathing was associated with a 28% decrease risk of heart disease and 26% lower risk of stroke.
从1990年开始到2009年底，对从45-59岁的健康研究参与者进行了大约19年的跟踪研究，研究人员发现，每天洗澡可以降低28%的心脏病风险和26%的中风风险。
On further study, the researchers found that water temperature also plays a significant role. Warm baths reduce the risk of heart disease by 26%, and hot showers reduce the risk of heart disease by 35%. The study found no correlation between water temperature and stroke risk.
在进一步的研究中，研究人员发现水温也起着重要的作用。热水澡可以降低26%的心脏病风险，热水淋浴可以降低35%的心脏病风险。研究发现水温和中风风险之间没有关联。
Bathing can affect heart health by helping to lower blood pressure and reduce the risk of hypertension. The warm water's temperature relaxes blood vessels and relaxes the body. This allows the blood to move through the veins and arteries much more easily, reducing the pressure and burden on the heart.
洗澡可以通过帮助稳定血压和降低高血压的风险来影响心脏健康。温水可以放松血管和身体。这样可以使血液更容易地通过静脉和动脉，减少心脏的压力和负担。
In particular, when stress is high, bathing can help calm nerves, separate from the stress of work, potentially lower blood pressure and reduce the risk of heart disease or stroke.
特别是，当压力很大的时候，洗澡可以帮助镇定神经，从工作压力中分离出来，潜在地降低血压和减少心脏病或中风的风险。

热水帮助身体放松，所以你会更容易入睡。水的热量可以放松肌肉，提高体温。当肌肉放松时，头脑就会变得更放松。这就是为什么在漫长紧张的一天结束后最好洗澡，洗澡时间不要超过20分钟。
Eliminate toxins
消除毒素
Sweating is a way for your body to eliminate toxins and waste products from the body, just like bathing can also help remove toxins from the body. Bathing can help open up your pores, help remove dirt and toxins inside the skin, giving you a fresher and cleaner skin. Besides, bathing will also remove and destroy bacteria and viruses on your skin, helping to reduce the risk of infection.
出汗是身体排出毒素和废物的一种方式，就像洗澡也可以帮助身体排出毒素一样。洗澡可以帮助打开你的毛孔，帮助清除皮肤内的污垢和毒素，让你的皮肤更清新、更清洁。此外，洗澡还能清除和摧毁皮肤上的细菌和病毒，有助于降低感染的风险。
Headache relief
缓解头痛
If you have headaches, this may be caused by constriction of the blood vessels. When you shower, hot water can reduce the pressure on your blood vessels and may help relieve headaches.
如果你头痛，这可能是由血管收缩引起的。淋浴时，热水可以减少血管的压力，有助于缓解头痛。
Improve immune system
改善免疫系统
A cold bath is also beneficial. Cold water can stimulate your lymphatic and immune systems, so your body can make more immune cells to fight infections, increase resistance and reduce the risk of disease.
冷水浴也是有益的。冷水可以刺激你的淋巴系统和免疫系统，所以你的身体可以制造更多的免疫细胞来对抗感染，增强抵抗力，降低患病风险。
Bathing helps treat depression
洗澡有助于治疗抑郁症
The importance of bathing can be seen from many perspectives. If you are depressed, you will benefit from a cold bath. Cold water can stimulate your nervous system, increasing the secretion of beta-endorphin and noradrenaline in the blood, thus helping to reduce depression. In addition, soaking in a cold bath can also transmit electrical impulses to the brain and act as an antidepressant.
洗澡的重要性可以从很多方面来看。如果你情绪低落，洗个冷水澡对你有好处。冷水可以刺激你的神经系统，增加血液中-内啡肽和去甲肾上腺素的分泌，从而帮助减轻抑郁。此外，泡在冷水浴中也能向大脑传输电脉冲，起到抗抑郁的作用。
Reduce stress
减轻压力
When you feel stressed, taking a hot bath can help relieve the stress. Cortisol and chromogranin are the two chemicals that control stress in your body. Cortisol and chromogranin will be reduced after 60 minutes of soaking in the hot tub.
当你感到有压力时，洗个热水澡有助于缓解压力。皮质醇和铬粒蛋白是控制你体内压力的两种化学物质。在热水浴缸中浸泡60分钟后，皮质醇和铬粒蛋白会减少。
Improved lung function
改善肺功能
When you take a cold bath, you will breathe deeper and harder. This is because when the body comes into contact with cold water, you tend to hold your breath for a few seconds after exhaling strongly, and this is the body's automatic response to improving lung function.
当你洗冷水澡时，你会呼吸得越来越深，越来越困难。这是因为当身体接触到冷水时，你会在强烈呼气后屏住呼吸几秒钟，这是身体对改善肺功能的自动反应。
Relieves muscle pain
缓解肌肉疼痛
Hot showers can increase muscle temperature and block pain sensors on the skin, which in turn can relieve muscle pain. Cold water can help constrict blood vessels and increase the excretion of lactic acid from the damaged area, helping to relieve muscle pain. When you get out of the bath, fresh, lactic acid-free blood flows into the sore muscles, causing the muscles to recover quickly.
热水澡会增加肌肉温度，阻断皮肤上的疼痛感受器，从而减轻肌肉疼痛。冷水可以收缩血管，增加受伤部位的乳酸排泄，帮助缓解肌肉疼痛。当你洗完澡后，新鲜无乳酸的血液流入酸痛的肌肉，使肌肉迅速恢复。
Reduce nasopharyngitis
减少鼻咽炎

洗澡有助于降低血糖水平
According to a study by the McKee Medical Center in Loveland, Colorado, USA people with diabetes soak in a hot tub for 20-30 minutes daily for 3 consecutive weeks have reduced blood sugar levels by approximately 13%.
