Why Are People More Prone to Catching a Cold When Exposed to Spring Breezes?
Spring breezes can easily lead to colds, typically due to large temperature fluctuations, dry air, rapid virus transmission, immune system variations, and inadequate protection. The details are as follows:

1. Large temperature fluctuations: During spring, there is a significant difference between day and night temperatures. After warming during the day, people tend to remove clothing, but when temperatures suddenly drop at night or in the wind, the body struggles to adapt quickly. This weakens the respiratory mucosal defense, making it easier for viruses to invade and cause colds.
2. Dry air: Spring winds accelerate the evaporation of moisture in the air, leading to dry environments. This causes the respiratory mucosa to lose moisture, weakening its protective barrier and reducing resistance to viruses, thus increasing susceptibility to infection.
3. Rapid virus spread: Warmer spring temperatures favor virus reproduction. Additionally, spring breezes increase the dispersion of respiratory droplets, prolonging the survival time of viruses in the air and raising the likelihood of exposure, thereby increasing the risk of cold transmission.
4. Immune system fluctuations: After winter, the body's immunity has not fully recovered. With increased physical activity and changes in daily routines during spring, some individuals may become overworked or stressed, causing a temporary decline in immunity and reduced ability to resist viral infections.
5. Inadequate protection: As the weather warms, people wear fewer clothes, open windows more often, and spend more time outdoors. If proper warmth retention and hand hygiene are neglected, viruses can more easily take advantage, leading to colds.
To stay healthy in spring, adjust clothing promptly according to temperature changes and avoid getting chilled from drafts. Maintain indoor humidity and drink plenty of water to keep the respiratory tract moist. If cold symptoms appear, rest promptly and manage your condition properly to prevent worsening.
