- Lean and harmful food.This reason can arise not only among people who, for life reasons, can not provide themselves with food to the fullest, but also for those who lead an unhealthy lifestyle.This may be due to their work or personality traits - breaks in meals are too long, and the brain does not receive all the substances necessary for its functioning.
- Visual fatigue.Some eye diseases, work at a height or associated with the function of observing objects lead to such a violation.When trying to change the focus and look at something else, there is a feeling that the objects are spinning or floating.
- Overloads associated with rapid movement.The center of balance preservation works in people differently and is not always able to cope with situations.This effect can occur when you are on the carousel, roller coaster, behind the wheel of a racing car.
- The influence of adrenaline.Any situation associated with anxiety, fright, leads to the release of adrenaline into the blood - a substance that is designed to help a person act in stressful situations.The vessels in the person's head may become narrowed, and oxygen stops coming into the brain in sufficient quantity.This is a survival mechanism, and such effects are normal.
- Medications.For many drugs, dizziness is a side effect.
- Vertigo is usually a pregnancy companion.The causes are iron deficiency, glucose, osteochondrosis, blood flow redistribution, diet compliance.
2 Harmful habits and their negative effects
Often the cause of the headache is bad habits.These include the following:
- Smoking often leads to such dizziness.Nicotine significantly dilates blood vessels.
- Alcohol.When alcohol enters the blood, the vessels expand throughout the body.Alcohol depresses the center of human equilibrium, it can lead to dizziness even in a horizontal position.In addition, a hangover and alcohol poisoning cause an increase in blood pressure, cerebral edema and thrombosis of the capillaries themselves.This also leads to dizziness and a host of other unpleasant effects for a person who can not stand the dose.
- Drugs.The effects of drugs are very different in nature, but many of them can cause dizziness.This is due to their destructive effect on the body.The use of smoking mixtures, which are considered among young people as "light" and "safe" drugs, can cause a hypertensive crisis and an attack of tachycardia.At narcomaniacs with the experience the head can be turned about owing to refusal of internal bodies.

- Diseases of the vestibular apparatus.Regardless of the posture, the muscle effort is distributed in such a way as to maintain the position of the body and maintain balance.For this, the vestibular apparatus and the brain regions( cortex and cerebellum) are responsible.
- Injury of inner ear and vestibular nerve.With head injuries, blood circulation in the inner ear can be disturbed, because of which the pressure on it will be increased.Also, the reasons may be a violation of the integrity of the structure of the inner ear, damage to its nerves or the formation of a tumor.
- Diseases of the nervous system.In neurological diseases, severe dizziness is not observed, seizures are smooth, develop for a long time and just as slowly pass.Atherosclerosis of cerebral vessels.This disease is associated with the clogging of blood vessels and capillaries of the brain with cholesterol plaques.The influx of blood to individual parts of the brain worsens, and oxygen starvation begins.Hence the dizziness.Injury to the skull.As a result of such damage, cerebral edema occurs, its blood vessels suffer and small hemorrhages occur.Symptoms vary depending on the severity of the lesion.
- Tumors of the brain.Malignant neoplasm presses on various parts of the brain, compresses blood vessels, causes accumulation of fluid.Depending on the location and size of the tumor, the symptoms may be different in severity of manifestation.
- Epilepsy.Vertigo is one of the main symptoms of this disease and the main predecessor of the seizure.
- Degenerative diseases of the brain, for example, multiple sclerosis.The symptomatology resembles the diseases of the inner ear, and the formulation of an accurate diagnosis can be complex and long-term.
- Migraine.The causes of migraine are still unknown, but dizziness is an ordinary companion of this disease.
- Psychogenic dizziness.It is associated with an incorrect reaction of the body to stimuli and stress.With stress, even minor, too much adrenaline is released, there is a headache, dizziness, weakness, rapid breathing, sweating, high blood pressure.
- Osteochondrosis.Disease of the spine, associated with a violation of posture or injuries.Seizures are observed after provoking an exacerbation of the disease: hypothermia, sedentary work or physical exertion.

- Poisoning.When the products of decay of poisons accumulate in the blood or fight immunity with severe infection, intoxication occurs, which also leads to dizziness and general deterioration of the condition.
- Disruption of absorption of nutrients in various diseases of the digestive system can lead to the fact that the body ceases to properly obtain the substances necessary for maintaining normal functioning.
