This article will combine the hot data on the Internet in the past 10 days to analyze the causes of dizziness after sun exposure and scientific solutions.
1. Statistics of hot topics related to high temperature on the entire network (last 10 days)
| Ranking | Topic keywords | Number of discussions (10,000) | Main platform |

1.dehydration symptoms: In high-temperature environments, the rate of body fluid loss is 3-5 times that of normal. When the water loss reaches 2% of body weight, dizziness symptoms will occur.
2.Thermoregulatory imbalance: When the core temperature of the human body exceeds 38°C, abnormal blood vessel expansion leads to insufficient blood supply to the brain.
3.electrolyte imbalance: Sweat loss will take away important electrolytes such as sodium and potassium, affecting nerve conduction function.
3. Emergency handling steps recommended by authoritative organizations
| steps | Operational points | Things to note |
|---|---|---|
| first step | Move to a cool place immediately | Avoid direct sunlight and choose a ventilated place |
| Step 2 | Supplement electrolyte-containing fluids | Oral rehydration salts are recommended and avoid drinking large amounts of ice water |
| Step 3 | physical cooling | Wipe your neck/armpits with warm water. Do not wipe with alcohol. |
| Step 4 | Raise lower limbs | Promote blood return and relieve cerebral ischemia |
| Step 5 | Monitor state of consciousness | If you experience vomiting or confusion, seek medical attention immediately |
4. Four effective measures to prevent sunburn
1.Scientific drinking water: It is recommended to add 200-300ml of light salt water containing 0.1%-0.3% salt every hour to keep the urine light yellow.
2.Wear protection: UPF50+ sun protection clothing can block 98% of ultraviolet rays, and the sun protection effect of the wide-brimmed hat is 3 times that of ordinary hats.
3.Avoid hot periods: The intensity of ultraviolet rays from 10 a.m. to 4 p.m. accounts for 70% of the whole day, so going out should be minimized.
4.diet regulation: Potassium-rich bananas (potassium 358mg per 100g) and lycopene-containing watermelon are ideal foods to prevent heatstroke.
5. Special reminder: You must seek medical treatment in these situations
When any of the following symptoms occur, you may have developed heat stroke and you need to seek medical attention immediately:
- The body temperature continues to be higher than 39°C and cannot be lowered
- Convulsions or disturbance of consciousness
- Stop sweating and dry and hot skin
- Heart rate exceeding 120 beats/minute
According to the latest data from the National Health Commission, the fatality rate of heat stroke can reach 20%-70%. Early identification and correct treatment are crucial. It is recommended to collect the emergency treatment methods mentioned in this article and forward them to relatives and friends who often engage in outdoor activities, so as to jointly prevent heatstroke and cool down.
