What could be the causes of dizziness near the seashore?

Generally, dizziness at the seaside may be caused by environmental adaptation dizziness, dehydration or hypoglycemia, heatstroke, hypotension, insufficient cerebral blood supply, and other factors. Symptomatic management through general treatment and medication may be needed. If symptoms are severe, timely medical attention is recommended, following medical advice for treatment. Detailed analysis is as follows:

1. Environmental Adaptation Dizziness

Upon first arriving at the seaside, due to high air humidity, strong winds, and other factors, one may experience mild dizziness. In such cases, dizziness is usually accompanied by a slight feeling of discomfort. It is recommended to rest in a quiet place, replenish fluids, and observe for several minutes to hours; symptoms typically resolve on their own.

2. Dehydration or Hypoglycemia

Extended activity at the seaside, especially under direct sunlight, may lead to dehydration or hypoglycemia, causing dizziness. At this time, activity should be stopped immediately, rest in a cool place, replenish fluids and consume sugary foods such as fruits and chocolate, while monitoring one's condition.

3. Heatstroke

Remaining exposed to high temperatures at the seaside for prolonged periods can prevent the body from dissipating heat effectively, possibly leading to heatstroke, with symptoms such as dizziness and nausea. It is recommended to use medications such as Huoxiang Zhengqi Water, Suhe Xiang Pills, and Shidi Shui under a doctor's guidance for treatment.

4. Hypotension

Irregular eating habits and an unbalanced diet may lead to hypotension. Sea breeze stimulation or seaside activities may further lower blood pressure, potentially causing symptoms such as dizziness, nausea, and vomiting. It is recommended to use medications such as Midodrine Tablets, Flunarizine Hydrochloride Capsules, and Propranolol Hydrochloride Tablets under a doctor's guidance for treatment.

5. Insufficient Cerebral Blood Supply

Long-term high-salt diet, alcohol consumption, and other factors may lead to elevated blood pressure, which can subsequently cause insufficient cerebral blood supply and result in dizziness. Additionally, the low atmospheric pressure environment at the seaside may cause blood to pool in the brain, leading to cerebral ischemia and hypoxia, thereby causing dizziness. It is recommended to use medications such as Aspirin Enteric-coated Tablets, Clopidogrel Bisulfate Tablets, and Rosuvastatin Calcium Tablets under a doctor’s guidance for treatment.

In daily life, it is recommended to maintain a healthy lifestyle, eat a balanced diet, and ensure adequate sleep, which can help alleviate dizziness symptoms.
