However, running is not as adaptable and fast as walking. Many people find it difficult to keep running, and some physical discomfort will occur after forced running. Dizziness is a common one. Here are three reasons for running dizziness, I hope to help everyone!
1, hyponatremia and hypokalemia cause dizziness and discomfort.
Running for a long time or in a high temperature environment may cause a lot of sweating, which not only causes the body to lose water, but also causes the loss of electrolytes. The most common is hyponatremia, which will not only cause dizziness, but also cause renal function damage if not treated in time, from diarrhea, dizziness and cramps to unconsciousness, coma and even death! In addition, low potassium can also make muscle excitability abnormal, which is not conducive to the maintenance of exercise state.
Therefore, if you want to run in a high temperature environment for a long time, you need to supplement not only water but also electrolytes. It is suggested to choose sports drinks with low permeability or isotonic permeability, which can quickly replenish water, electrolyte and sugar, while sports drinks with high osmotic pressure have higher sugar content, slower hydration speed and higher calories, so you should choose according to your own needs!
2, hypoglycemia and anemia lead to dizziness.
Hypoglycemia is not only a patent for diabetics, but also happens to young people, such as skipping breakfast, being too thin or exercising too much! Many friends who just started fitness don't know their physical fitness. Excessive exercise leads to the exhaustion of glucose in the blood, while the muscle mass is low and the muscle glycogen reserve is insufficient, which can not support blood sugar in time, leading to hypoglycemia! It is suggested that friends who often have hypoglycemia should not exercise vigorously or for a long time, but also pay attention to muscle gain. In addition, you should replenish energy before exercise, such as bread, jujube and other snacks that can quickly release sugar!
An important function of iron in human body is to form red blood cells and deliver oxygen to muscles. When the iron content is insufficient, it will easily lead to iron deficiency or anemia, which will affect the performance of runners. Many girls themselves often have cold limbs and pale lips. It is very likely that they have anemia symptoms, but they just don't know it! Moreover, running with high oxygen consumption requires high cardiopulmonary function, which is likely to make friends with anemia or iron deficiency dizzy because of lack of oxygen! It is recommended that friends who are often dizzy, cold hands and feet, pale lips and nails and conjunctiva eat more red meat, animals and liver. If the situation is serious, you should see a doctor for iron supplementation!
3. Low blood pressure leads to dizziness
When we run, blood vessels dilate, muscles contract and the heart pumps blood faster. This process not only meets the energy demand of running, but also accelerates the blood return to the heart, increasing the amount of blood returned to the heart through veins, which can increase the amount of oxygen needed for running. However, when running to the finish line, the range of motion of the leg drops instantly, which makes the heart lose the strong support of muscle-assisted blood pumping, resulting in more blood staying in the limbs, which leads to lower blood pressure and adverse reactions such as dizziness and nausea. I suggest you slow down gradually at the end of the run, from fast running to jogging, and then gradually to fast walking and slow walking until you stop. Never slow down instantly!
In addition to the above three reasons, people with heart and lung diseases are not recommended to run. If you feel unwell during running, you should stop to rest in time and go to the area where people are concentrated to prevent no one from asking for help in an emergency.
However, friends with excessive body mass index (BMI greater than 28) should gradually transition from walking to running, otherwise the joint load will be too heavy, which will easily lead to sports injuries; In addition, you must do enough preparatory activities before running. Suggest 8~ 15 minutes, and then start running!
