Blinking too often or not blinking can be a problem. [사진=게티이미지뱅크]Depending on how often we blink, we can recognize the diseases hidden in them. Typically, adults blink once every 3 to 5 seconds. This serves to replenish moisture and prevent our eyes from drying out. However, blinking too often or not at all can be a problem. They range from Parkinson’s disease to allergies. Discover the diseases linked to the degree of blinking introduced by The Sun.
Parkinson’s disease
According to several studies, the speed with which we blink reflects the amount of dopamine in our brain. If you have less dopamine, you focus more on one topic and blink less often. People with Parkinson’s disease don’t have enough chemical dopamine in the brain because some of the nerve cells that produce dopamine have stopped working. This makes you blink less or your hands shake.
Graves’ disease (thyroid)
Blinking less often may be due to an overproduction of thyroid hormones (hyperthyroidism), and one of these could be an immune system disorder called Graves’ disease. Autoimmune diseases increase the body’s metabolic rate, leading to weight loss and low energy levels. Other signs include anxiety, tremors, sensitivity to heat 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 blinks.
cerebral hemorrhage
In addition to Parkinson’s disease, like stroke, neurological problems can slow down normal blinking. This is because the eyelid nerves, facial nerve and eyelid muscles can become damaged. Stroke is a fatal disease that occurs when the blood supply to part of the brain is blocked. Without blood, brain cells can die or become damaged, and symptoms include slurred speech, numbness, weakness, or paralysis of the face, arms, or legs.
head trauma
If you hurt your head during physical activity, your eyelids may blink less than usual. There can be many reasons, including brain hemorrhage, so if you blink less than usual, you should see a doctor.
Sjogren’s syndrome
When we perform difficult tasks, such as driving while drowsy, we tend to blink more often. This is to protect your eyes while 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 usually 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, 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 into 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 related to Tourette’s syndrome. In the UK, Tourette’s 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.
