1. General weakness and back pain. Long-term high load and fixed mode of work will lead to muscle, cervical spine and other parts of the soreness symptoms. The state of high energy consumption will also lead to an increase in the body’s demand for oxygen, and this state of relative lack of oxygen will cause dizziness and weakness. It is recommended that daily deep breathing exercises can relieve stress and increase the oxygen level in the body. Taking time for deep breathing exercises every morning, noon and night can effectively relieve the symptoms of back pain and fatigue. If you have plenty of time, you can also try to completely empty yourself and meditate. You can also go for a walk in the countryside on your day off, away from the noise and fresh air, so that the pressure can be released. 2, talking to yourself, sensitive and suspicious. The human body is under long-term stress, high nerve tension, the brain is in a long-term “alarm” state, the surrounding things will become very sensitive, once the wind blows, the brain will appear excessive vigilance, and even often appear to talk to themselves. Long-term high-load operation will make people enveloped in anxiety, helplessness and fear, which leads people to pay special attention to the ideas and opinions of others, fearing that their words and actions inappropriate to cause unnecessary trouble, leading to unwarranted suspicion of the people around them.

Overwhelmed with power and poor sleep. If the heavy task makes people overwhelmed is understandable, then the usual seemingly ordinary work will make people feel overwhelmed to pay attention to. Under stressful conditions, people’s ability to grasp and analyze information will be affected, mainly in terms of attention and reaction speed.

After some people enter middle age, teeth become sensitive to hot, cold, sour and sweet stimuli, which is actually the alarm sent by teeth to the body. Sensitive teeth may indicate oral diseases such as dental caries, periodontitis and tooth decay, resulting in the growth of bacteria in the mouth and oral odor. Generally speaking, human teeth start to discolor and the enamel becomes thinner around the age of 30; at the age of 40, the tooth bed starts to shrink, the roots are gradually exposed, and the length of the teeth sometimes grows compared to that of younger years. In addition, tooth pain when eating irritating foods, brittle and cracked teeth, red and swollen gums accompanied by bleeding, and loose teeth are all signs of aging. Some studies have shown that the appearance of periodontitis is associated with diabetes, coronary heart disease and erectile dysfunction, and may be an early manifestation of cardiovascular disease. Therefore it is necessary to maintain oral health, usually to carefully clean the mouth, brush teeth can not be haphazard, oral health is not only related to the entire digestive system, but also related to the whole body cardiovascular system. 5, poor urination, urinary frequency and urgency. People always want to go to the toilet when they are nervous is a normal reaction, but there is a condition that needs attention. Increased nighttime urination and frequent and urgent urination may not only be caused by stress, but may also be an early warning signal when the body is going senile. Due to factors such as declining bladder function and prostate enlargement, abnormal urinary function can occur from the age of 40 onwards. When people reach the age of 50, the number of nighttime rises increases significantly, and some people have difficulty “controlling” their bladders by age 65. To prevent aging of the bladder, it is important to develop the habit of not holding urine, especially for drivers, long-term sedentary office workers and other occupational groups. Usually try to avoid alcohol, tobacco and spicy dietary stimuli, avoid drinking too much coffee, tea and other beverages before bed. 6, decreased libido, erection is poor. The quality of sexual life is the weather vane of human health, when there is a loss of libido, erectile dysfunction, premature ejaculation, etc., must pay attention to check whether there are problems in the body. When libido is reduced, many people are likely to have late onset hypogonadism, and if it occurs in middle age, it suggests the possibility of premature aging and early onset of androgen reduction. If erectile dysfunction is present, it is important to pay high attention to whether cardiovascular problems are present, as erectile dysfunction is now considered to be a vane of cardiovascular disease. In case of premature ejaculation, consider the presence of diseases such as chronic prostatitis and hyperthyroidism in the body. The study found that people who have sex twice a week have a lower incidence of cardiovascular disease and a lower overall mortality rate than those who have sex less frequently, which means that regular sex is not only good for your health, but also good for early detection of early warning signs in your body.
