Interesting Facts About Dizziness: Do You Want To Know The Causes?

Dizziness is a common term which describes sensations of unsteadiness and imbalance, like mild turning, vertigo, imbalance, and near fainting or even fainting. Dizziness, vertigo, and the balance-related conditions are some of the prevalent health problems in adults.
Infrequent dizziness is so common in adults, but it may surprise you to know that vertigo -a related but more severe condition which makes you feel like the entire room is spinning as you stand still -affects about 40% of people over 40 year at least once, with females slightly more likely to get it than males.
Feelings of dizziness can occur due to a problem with the vestibular system of the body that includes vestibular nerve, structures of the inner ear, cerebellum and brainstem, a region of the brain which integrates the sensory coordination, perception, and motor control. This system regulates posture, balance and the orientation of the body in space.
Although dizziness can affect your body balance for a very short period, and ranges from merely irritating to seriously debilitating, vertigo may be the main symptom of the balance disorder. Also, it can cause nausea and vomiting. Here are some of the top interesting facts about dizziness:
1. The Balance System of Your Ears Controls Blood Flow
Our inner-ear balance system plays a crucial role in controlling our blood flow, and the inner ear is capable of knowing which way is up, much like the Apple watch.
When you stand up after lying down for quite some time, whether on the bed or any other place two inner ear structures, the saccule and utricle, detect gravity automatically. They alert your cardiovascular system to direct the flow of blood to accommodate the change in position. If the process is altered for any reason, a person could end up feeling dizzy.
2. Dizziness May Be a Sign of the Heart Disease
Sudden movement is one of the common causes of dizziness, like when you stand up too suddenly from your bed or seat. But sometimes dizziness is a symptom of the heart condition. Some of the cardiovascular-related causes of dizziness include narrow or leaking heart valves, atherosclerosis, and arrhythmias such as atrial fibrillation. According to VEDA, these can cause severe dizziness since they lower blood flow to the brain.
3. Dizziness May Be Linked to Anxiety
Most people who experience dizziness particularly those in their twenties may have anxiety as well. They often do not want to believe that dizziness can be related to anxiety, since it suggests that it is all in their heads. However, what is in your head is your brain. Therefore, anxiety can reflect the disturbance of a brain function which is possibly genetic.”
Compared to those who do not have anxiety, individuals with the anxiety disorders seem to sway more when they’re subjected to any moving visual environment. And they sway in a manner which appears to be synchronized with a visual movement.
These individuals may be unusually sensitive to the visual stimulation, since their dizziness can increase when they are walking through a huge, bright store or watching moving objects. This is referred to as visual dependence; little is known about how prevalent it is.
Scientists need to come up with better tests of the visual dependence, and the laboratory tests for what is now referred to as anxiety disorders. It is possible that in the future, most of these disorders will end up being reclassified, in part, depending on the genetics.
4. Dehydration or Diet can cause dizziness
According to the American Heart Association, even mild dehydration can make you dizzy. Also, dehydration can lower the blood pressure, which can lead to dizziness, notes the AHA.
On the other hand, dieting can result in feelings of dizziness, since some diets often cause dehydration. Mild dehydration which follows the loss of only 1-2% of your body weight can cause dizziness according to the AHA.
5. Water Bed or A Boat Ride Can Cause Dizziness
It is very common to experience a shaky, dizzy feeling on your first day back after a cruise. For some people, this feeling, known as Mal de debarquement, can last for several months or even years.
Some 75% of all sailors can experience this problem. Trains, cars, and airplanes can also cause the wobbly-legs feeling. And even relaxing on the water bed can make some individuals feel dizzy.
