Studies have proven that the average water loss per hour for a person weighing 70 kg is about 2% of body weight, and this number becomes even greater when strenuous activity is performed. The feeling of thirst occurs when a person’s fluid level drops to the point that it interferes with the performance of normal physiological functions, which is actually when. It is already in a state of mild dehydration. Many people often feel headaches, back pain, back pain, but can not find any reason to do so, it is likely to be caused by dehydration of the body. Because 75% of the upper weight of the body is supported by the water stored in the intervertebral disc pores, the body’s long-term chronic dehydration can lead to headaches, back pain, back pain, and minor pain and discomfort throughout the body. There is a complete set of water storage system in the human body, and this system stores about 70% of body weight of water in the human body, so that human beings can adapt to temporary water shortage in a short period of time. At the same time, there is a drought management mechanism in the human body, the main function is to strictly allocate the stored water in the body when the body is dehydrated. The principle is: let the most important organs get sufficient amount of water and nutrients transported by water first. So the other organs become underhydrated. At this point, they will send out alarm signals of thirst, indicating a local water shortage; however, people mistakenly give it tea, coffee, wine or drinks, because they contain a large amount of factors of dehydration, which will not only make the water entering the body quickly excreted, but also take away the water stored in the body. This is the reason why the more we drink tea, coffee, wine or drinks, the more we want to urinate. Over time, the metabolic function of water will be disrupted and the drought management mechanism will not only signal thirst, but will show many more symptoms than “thirst”: back pain, neck pain, peptic ulcers, elevated blood pressure, asthma and allergies, and insulin non-dependent diabetes. For the sake of health, please remember to drink water often, never drink water only when you are thirsty! 1.Does the weather affect pain? Answer: Correct. Some people will think that the impact of weather on pain is a lot of psychological effect, in fact, chronic pain and weather changes are related to a certain extent, encountering rainy weather changes in external atmospheric pressure will lead to changes in the internal pressure of the major joints of the human body, so patients suffering from osteoarthritis in the rainy days when the pain symptoms will increase. In addition, when the outside temperature is low, the blood circulation in the body will slow down, the metabolic products in the body tend to accumulate around the joints or limb ends, which is also one of the causes of pain. 2.Women are more tolerant to pain? Answer: Unknown. When it comes to pain, we always raise the birth of a child, thinking that this is the limit of pain that humans can bear, so it is believed that women are more tolerant of pain. And in daily life, there is a difference in the attitude of men and women towards pain. Women will be more active in seeking ways to relieve pain when they encounter it, such as finding a doctor, so they will also be relieved from pain more quickly.

So, tough guys, don’t be too tough. 3, when the back pain, bed rest is the best treatment? Answer: Wrong. Although bed rest will improve low back muscle spasm and relieve pain for a short period of time, experts recommend that daily activities should be maintained. Prolonged bed rest will make our muscles lazy and when you are getting up to exercise, you will find that the pain will be worse instead. The correct approach is to rest in bed during the acute phase of low back pain, and when there is improvement in symptoms, make every effort to resume daily activities and exercise to a degree that does not aggravate the pain. For severe pain, it is important to seek medical attention in a timely manner and improve relevant examinations, except for tumors, fractures, herniated discs and other diseases. 4.Exercise can relieve pain? Answer: Correct. Although pain can limit our activities, proper exercise is one of the best tricks to keep away from pain as soon as possible. Exercise can help us lose weight, improve the quality of sleep, and improve mood, further relieving pain symptoms. Exercise can also strengthen muscles, improve joint stiffness, and increase flexibility and agility. For people who have been out of exercise for a long time, walking, swimming and climbing are great ways to help you get back into the sport. In fact, exercise will cause the brain to produce endorphins, a substance similar to morphine, giving people a sense of pleasure and satisfaction, so it is easy to understand why some people are addicted to running. Refuse to be lazy, exercise it, for yourself and your family. 5.Does your attitude affect pain? Answer: Correct. Thinking about pain all the time will make it more intense. Compared with those who are positive and optimistic, easy to focus more attention on the pain will make the pain more intense and last longer. Appropriate distraction will reduce the pain. This explains why many diseases tend to worsen pain at night, because there are other things that distract during the day, while at night it is easier to focus on the pain. Chronic pain stimulation can lead to depression and anxiety, which in turn can worsen the pain, creating a vicious cycle. So seeking help from a pain doctor as soon as possible is the right thing to do. 6, painkillers can become addictive? Answer: Wrong. As long as pain medication is taken as prescribed by a doctor, drug dependence or addiction is extremely rare. However, there are some neuropathic pains that require long-term medication to suppress neuroexcitability, such as trigeminal neuralgia, and the symptoms may worsen without medication. Many drugs need to be stopped slowly in a stepwise manner to avoid rebound of symptoms and abandonment of previous work.
