It’s the right time to protect your health in early spring when the weather is still cold

In early spring, the ground warms up and the grass and trees sprout, but cold air still moves frequently, and the temperature difference between day and night can reach more than 10℃. This "late spring cold" climate characteristic puts human physiological regulation under severe test. According to statistics, the number of respiratory outpatient visits in my country from March to April each year increases by 30% compared with winter, and the number of cardiovascular emergencies increases by 15%. It is particularly important to take good health protection during this period.

1. The "three sharp swords" of early spring climate

1. Temperature difference trap: When the daily average temperature difference exceeds 8°C, the frequency of blood vessel contraction and expansion increases, which can easily induce blood pressure fluctuations

2. Wind invasion: The spring wind, with an average speed of 4-5 m/s, carries allergens such as pollen and dust mites.

3. Humidity: Relative humidity rises above 70%, creating a breeding ground for pathogenic microorganisms

2. Warning of four common diseases

1. The respiratory defense line is in danger

- The activity of influenza virus has increased, and the positive detection rate of influenza A has increased by 40% compared with winter.

- The recurrence rate of chronic bronchitis increased by 50%, and the incidence of pneumonia in children reached the annual peak

2. Allergy Storm Hits

- Pollen concentrations exceeding 50 grains/1,000 square millimeters may induce allergic reactions

- Outpatient visits for allergic rhinitis increased threefold, and emergency visits for asthma doubled

3. Frequent cardiovascular alarms

- The incidence of myocardial infarction between 6 and 10 a.m. is 30% higher than other time periods

- The morning peak of blood pressure is significant, and the systolic blood pressure fluctuation can reach 20mmHg

4. Gastrointestinal dysfunction

- The reproduction rate of food-borne pathogens such as Salmonella has increased by 2 times

- Functional dyspepsia consultations increased by 25%

3. Scientific protection "Five-dimensional strategy"

1. Dress wisely

- Dress in an "onion style": quick-drying inner layer, warm middle layer, windproof outer layer

- Focus on protecting the "three necks": neck, wrist neck (pulse gate), ankle neck

2. Dietary adjustment

- Daily supplement of high-quality protein of no less than 60g (2 eggs and 100g lean meat)

- Increase intake of foods containing quercetin (apples, onions) to inhibit histamine release

- Drink 300ml of warm salt water in the morning to maintain the mucosal barrier

3. Environmental Control Guidelines

- Maintain indoor humidity at 40-60% and ventilate for 10 minutes every 2 hours

- Use HEPA filter purifier to reduce allergen concentration by 50%

4. Exercise prescription

- Perform Tai Chi, Ba Duan Jin and other gentle exercises after sunrise

- 150 minutes of moderate intensity aerobic exercise per week

5. Immune Enhancement Program

- Supplement vitamin D 800-1000IU/day to regulate immune balance

- Get a flu shot (60-70% effective)

- Ensure 6-8 hours of deep sleep to promote lymphocyte regeneration

Special reminder: Patients with chronic diseases should strengthen morning monitoring, and blood pressure measurement should be performed before taking medicine, after urinating, and after sitting for 5 minutes. If there is a persistent cough for more than 2 weeks, chest tightness for more than 30 minutes without relief, etc., you should seek medical attention immediately.

In early spring, health preservation emphasizes "keeping warm in spring and cold in autumn", but more importantly, scientific protection is required. Only by establishing a health shield consisting of a temperature buffer layer, a nutritional protection network, and an environmental isolation zone can we maintain the health line when all things recover. Remember, the best treatment is prevention, and the smartest health care is to follow the weather.
