Why do I experience dizziness and vomiting when using the internet?

Generally, dizziness and vomiting during internet use may be caused by eye strain, improper posture, anxiety or panic attacks, migraines, hypertension, and other factors. Symptomatic management through general treatment and medication may be necessary. If discomfort occurs, prompt medical consultation is recommended to receive appropriate treatment under a physician's guidance. Detailed explanations are as follows:

1. Eye Strain

Staring at a computer screen for extended periods can overwork the eyes, causing blurred vision and increased intraocular pressure, which may further lead to symptoms such as dizziness, headache, and nausea. It may also be accompanied by dryness and eye pain. It is recommended not to stare at the computer screen for long periods; instead, take breaks by gazing into the distance or performing eye exercises to alleviate eye strain.

2. Improper Posture

Maintaining the same posture for a prolonged period can keep the neck and shoulder muscles in a constant state of tension, resulting in poor blood circulation and reduced blood supply to the brain, which can cause dizziness. This may be accompanied by symptoms such as neck stiffness and shoulder or back pain. It is advisable to adjust your sitting posture and use ergonomically designed chairs and desks.

3. Anxiety or Panic Attacks

Exposure to excessive information, social comparisons, or cyberbullying while browsing the internet can increase psychological stress, triggering anxiety or panic attacks. In an anxious state, the body releases large amounts of stress hormones, such as adrenaline, causing increased heart rate and elevated blood pressure, which can lead to sensations of dizziness and nausea. These symptoms may be accompanied by palpitations, rapid breathing, and sweating. Practicing relaxation techniques such as deep breathing and meditation can help alleviate anxiety.

4. Migraine

Migraine is a neurological disorder; light stimulation and screen flickering during internet use may trigger abnormal electrical activity in the brain, leading to migraine attacks. During a migraine episode, cerebral blood vessels dilate and inflammatory substances are released, causing symptoms such as headache, dizziness, and nausea. It may also be accompanied by photophobia, phonophobia, and visual disturbances. It is recommended to follow medical advice and use medications such as ibuprofen tablets, indomethacin tablets, and nimodipine tablets to relieve symptoms.

5. Hypertension

Extended periods of internet use may lead to elevated blood pressure. Hypertension increases the pressure exerted on the walls of blood vessels during blood flow. If blood pressure continues to rise without control, it can lead to increased intracranial pressure, causing symptoms such as dizziness or nausea. It may also be accompanied by headache and palpitations. Antihypertensive medications such as nifedipine tablets, amlodipine maleate tablets, and methyldopa tablets should be taken as directed by a physician to lower blood pressure.

When experiencing discomfort, it is recommended to stop using the internet immediately, lie down and rest in a softly lit and quiet environment, relax both physically and mentally, and relieve visual and mental fatigue.
