I feel dizzy and about to fall down. What's going on?

I believe many people have experienced standing in the sun on the playground during large-scale activities in junior high and high school. Sometimes they would stand for a whole morning. Many students with poor health felt dizzy, and some even fainted. So in this case, teachers would usually keep the students with poor health in the class and not let them participate, for fear of accidents during the activities. What is going on when I feel dizzy?

1. During the hot summer, workers who work indoors will sweat a lot, causing dehydration. If they do not replenish water in time, they will easily suffer from heatstroke when the temperature is relieved. Heatstroke is a disease that often occurs in summer. The typical symptoms are dizziness and fatigue. If you feel dizzy and weak after doing outdoor work, and have symptoms similar to a cold, it is very likely that the dizziness is caused by heatstroke, and you need to take anti-heat medication in time.

2. Anemia patients are prone to dizziness. Sometimes after a lot of work, they feel dizzy and exhausted. Dizziness often occurs when standing up after squatting, and may be accompanied by symptoms such as nausea and vomiting. Anemia patients need to supplement iron in time and obtain nutrients from food. Many foods in our life have the effect of replenishing blood, such as red dates, apples, cherries, spinach, etc. Eating them can improve the symptoms of anemia and avoid dizziness caused by anemia.

3. The most common symptom of a cold is dizziness. During a cold, patients always feel weak, groggy, and have no motivation to do anything. Because colds can easily cause fever, sore throat, and dizziness, you need to take cold treatment medicine in time. Once the cold is relieved, the dizziness symptoms will gradually disappear. If the dizziness is caused by a cold, it is recommended that the patient drink ginger water to help drive away the cold. The dizziness symptoms will be relieved after the body dissipates the heat.

4. People who stay up late and work overtime for a long time have low immunity. Because of insufficient rest time or poor sleep quality due to insomnia, the brain cannot get enough rest, which can also cause dizziness. Therefore, people who often stay up late to work overtime need to take proper supplements and eat more foods that replenish blood and qi, help blood circulation, and reduce the harm of staying up late to the body. If you have insomnia symptoms, you need to eat foods that help you sleep and calm your nerves. Improving sleep can relieve dizziness symptoms.

5. High blood lipids and increased platelets can cause excessive blood viscosity and slow blood flow, leading to insufficient blood supply to the brain, and easily causing symptoms such as fatigue, weakness, and dizziness. There are many causes of hyperlipidemia, most of which are related to the patient's daily diet. Timely adjustment of diet is needed to relieve dizziness.
