Blinking too often or not blinking can be a problem. [사진=게티이미지뱅크]Depending on how often we blink, we can recognize hidden diseases in them. Typically, adults blink their eyes once every 3 to 5 seconds. This is to replenish moisture and keep our eyes clear from drying out. However, blinking too often or not blinking at all can be a problem. They range from Parkinson’s disease to allergies. Find out about diseases related to the degree of eye blinking introduced by The Sun.
Parkinson’s disease
According to several studies, the rate at which we blink reflects the amount of dopamine in our brain. If you have less dopamine, you focus more on one subject and blink less often. People with Parkinson’s disease don’t have enough of the chemical dopamine in their brains because some of the nerve cells that produce dopamine have stopped working. This causes you to blink less or your hands to shake.
Graves’ disease (thyroid)
Blinking less often can be due to overproduction of thyroid hormones (hyperthyroidism), and one of them may be an immune system disorder called Graves’ disease. Autoimmune diseases increase the body’s metabolic rate, leading to weight loss and low energy. Other signs include anxiety, tremors, heat sensitivity, and irregular heartbeat. Two in 100 people in the UK suffer from Graves’ disease, and a third also suffer from eye problems. The eyeball protrudes and the eyelids contract, resulting in a decrease in the number of eyelid blinks.
cerebral hemorrhage
In addition to Parkinson’s disease, such as stroke, neurological problems can slow down the normal blink rate. This is because the eyelid nerves, facial nerve, and eyelid muscles may be left damaged. Stroke is a fatal disease that occurs when blood supply to part of the brain is blocked. Without blood, cells in the brain can die or become damaged, and symptoms include slurred speech, numbness, weakness, or paralysis of the face, arms, or legs.
head trauma
If you injure your head while exercising, your eyelids may blink less than usual. There can be many reasons, including cerebral hemorrhage, so if you blink less than usual, you should seek medical attention.
Sjögren’s syndrome
When we do difficult tasks, such as driving while drowsy, we tend to blink more often. This is to protect your eyes as your body reacts to fatigue. One of them is Sjögren’s syndrome. It is an autoimmune disease that causes widespread dryness of areas of the body that produce body fluids such as tears and saliva.
Dry eye caused by Sjögren’s disease can cause itching or burning and increase blinking. It typically begins between the ages of 40 and 60 and occurs much more commonly in women than men. The cause of this disease has not yet been discovered.
allergy
When allergies occur, eye blinking may increase. Allergens that can cause allergic reactions include mold, pollen, house dust mites, cosmetics, and animal dander. When we are exposed to external irritants, the body sometimes responds by releasing histamine in the eyes. At this time, the blood vessels in the eyes stretch and become larger, and the eyes become red and itchy, causing frequent blinking.
Tourette Syndrome
Frequent blinking may also be a tic disorder related to Tourette syndrome. In the UK, Tourette syndrome affects around 1% of the population, and these tics are sudden, uncontrollable movements, such as exaggerated or persistent blinking. The cause is unknown, but experts believe there is a problem with part of the brain.
