It is easy to get dizzy in the summer when it is hot, especially for some elderly people whose thermoregulatory ability starts to deteriorate, so it is easy to get dizzy in the summer, but did you know that? Dizziness is not always caused by the heat, so what else is the cause? Then look below you will know. 1, hypotension, hypoglycemia On the one hand, the weather becomes hot, sweating increases, the body surface volatile water increases, playing a certain “diuretic” effect, causing the body to lose a certain amount of fluid volume. On the other hand, the increase in external temperature, the expansion of blood vessels on the human body surface and the increase in the volume of the vascular bed further aggravate the relative lack of human fluid volume. The combined effect of these two factors leads to lower blood pressure, and even hypotension. How to avoid this situation? The method is actually very simple, regular monitoring of blood pressure is sufficient. The dizziness caused by hypoglycemia is mostly seen in diabetic patients, normal people do not have hypoglycemia, it usually occurs when insulin is used too much or no meal situation, blood sugar suddenly drops, blood sugar is too low may appear impaired consciousness, and even life-threatening. If this happens suddenly, the family can feed the patient to eat a piece of sugar, or drink sugar water, can be alleviated. 2, may be heatstroke In a hot environment, once a person appears sweaty, thirsty, weakness, dizziness, dizziness, tinnitus, nausea, palpitations, inattention and other aura of heatstroke, the patient himself can take a series of self-help measures, such as applying cool oil, anthritis, etc. on the forehead, or taking medicines such as Ren Dan, ten drops of water, Huo Xiang Zheng Shui. If the surrounding people find that the next person has symptoms of heat stroke, they should immediately move them to a cool and ventilated place, and call 120 as soon as possible to send the hospital for treatment. 3, cervical spondylosis can also cause dizziness Dizziness caused by cervical spondylosis has a distinctive feature that is clearly related to changes in body position, and patients generally feel dizzy when they suddenly turn around, or even faint. Vertebral artery type cervical spondylosis accounts for about 10% to 20% of cervical spondylosis, and patients are generally over 50 years old. If they are ill, they must be treated promptly, and it is very dangerous if they faint while riding a bicycle to look at a traffic light. To diagnose whether there is vertigo caused by cervical spondylosis, it can be done by MRI or angiography, which place is narrowed and squeezed basically. Many women eat very little or purely vegetarian food in summer to keep their body shape, so their basal metabolic rate is lower than normal people, so the gastrointestinal movement is slower and gastric acid secretion is less, which will affect the absorption of nutrients, plus the monthly physiological period of women, which will easily produce symptoms of anemia such as dizziness and weakness. 5, beware of “cerebral infarction” The hottest season of the year is approaching, the body sweats more, the body water loss increased, especially the elderly body water itself is less than young people, coupled with a more sluggish physiological response, resulting in blood concentration, and even “dehydration”, resulting in increased blood viscosity, leading to increased blood viscosity. This leads to an increase in blood viscosity, which can lead to stroke (i.e., cerebral infarction). Summer should be moderate physical activity, such as walking, jogging, etc., timely treatment of diabetes, coronary heart disease, liver and kidney insufficiency and other diseases, blood pressure control at normal levels, while paying attention to the ban on smoking and alcohol control. 6, beware of air conditioning disease It is understood that air conditioning disease is mainly manifested as dizziness, fever, dry eyes, joint pain, muscle pain and other symptoms, and air conditioning disease caused by many reasons, the most important point is that the summer indoor temperature is too low, prolonged blowing air conditioning will make the cold stagnation in the body. In addition to these diseases, dizziness may be induced after poor rest, sudden increase in exercise, excessive eye use, and taking anti-cold medication, etc. Generally in this case, dizziness will be relieved after rest or stopping the act.
