Dizziness when it is hot may be related to insufficient blood supply to the brain, or it may be caused by iron deficiency anemia, high blood pressure and other reasons.
1. Insufficient blood supply to the brain: if you stay in a hot environment for a long time, which leads to a lot of sweating, due to excessive sweating, it is easy to cause insufficient blood volume, which will cause insufficient blood supply to the brain, thus dizziness symptoms.
2. Iron deficiency anemia: Due to the decrease in the content of red blood cells in the blood, the oxygen-carrying capacity of the blood is reduced, resulting in chronic oxygen deprivation in the brain. Coupled with the environment is too hot, resulting in the expansion of blood vessels throughout the body, resulting in an increase in peripheral blood supply, resulting in a decrease in the effective circulation of the body’s blood volume, which may aggravate the ischemia of the brain tissue, hypoxia, which will cause dizziness.
3. Hypertension: If the patient is in a hot environment for a long time, it is easy to cause blood pressure fluctuations, resulting in increased pressure inside the cerebral blood vessels, dizziness will occur, and may be accompanied by headache, nausea and other manifestations.
A hot dizziness, may also be caused by other reasons, if accompanied by other discomforts, should consult a doctor as soon as possible, after diagnosing the cause, give targeted treatment.
