From Araw to Aircon: How Temperature Swings Affect Immunity

Published: 11:01 AM, January 30, 2026

It’s not just the weather!

In the Philippines, it’s common to blame sudden colds or sniffles on unpredictable weather. One moment it’s blazing hot under the sun, suddenly you’re shivering in an air-conditioned room. While it may seem like the culprit is the climate itself, the reality is more nuanced— temperature swings, rather than just the weather, can affect our immune system.

Temperature Swings and Immune Balance

Our immune system is designed to fight off viruses and bacteria. Sudden changes in temperature, however, can disrupt its balance. When your body moves quickly between different spaces, it needs to work harder to maintain a stable internal temperature. This extra effort places stress on the body’s regulatory systems, that can lead to weakening its defenses.

Temperature fluctuations can affect the immune system in several ways:

  • Stress on Temperature Regulation
    Rapid cooling or heating forces your body to divert energy to stabilize temperature, which can reduce the efficiency of other immune responses.
  • Drying and Irritation of Airways
    Air-conditioned environments often have lower humidity, which dries out the nasal passages and throat. These tissues serve as the first line of defense against pathogens foreign pathogens.
  • Sleep Disruption
    Uncomfortable temperatures can interfere with quality sleep. Sleep is crucial for antibody production and overall immune health.
  • Increased Viral Exposure
    Public spaces like offices, malls, and classrooms often recirculate air through air conditioning, increasing exposure to airborne viruses, particularly when your immune system is already stressed.

The good news is that there are simple ways to help your body cope with temperature swings:

  • Gradual Transitions
    Avoid sudden exposure to extreme temperatures. Give your body a few minutes to adjust when moving from hot to cold environments.
  • Proper Hydration
    Staying hydrated helps maintain healthy mucous membranes in your airways, which act as a natural barrier against infections.
  • Regulated Room Temperature
    Set air conditioners to a moderate temperature to prevent sudden shocks to your system.
  • Support with Immunity Supplements
    Incorporating immune-supporting nutrients can give your body an extra layer of protection. CM-Glucan, a natural immunomodulator, is shown to produce more antibodies than Vitamin C.

Immunomax is made with CM-Glucan, that produces more antibodies than Vitamin C and helps your immune system stay balanced with proper diet and exercise. 

By understanding how your body reacts and taking practical measures such as gradual transitions, hydration, regulated temperatures, immune-supporting supplements like CM-Glucan, you can help keep your immune system balanced without letting environmental changes dictate your wellness and proper diet and exercise.

MAHALAGANG PAALALA: Ang Immunomax at Immunomax Forte ay hindi gamot at hindi dapat gamiting panggamot sa anumang uri ng sakit.
