Why Do We Get Sick When Seasonal Changes?

Last updated on January 26th, 2023 at 01:29 pm

This article explores the reasons why our bodies are more susceptible to illness during seasonal changes. Learn about the environmental factors that can affect our health and how to protect ourselves from getting sick.

Introduction

As the seasons change, many of us may find ourselves getting sick more often. Whether it’s a cold, the flu, or allergies, it can be frustrating to have to deal with illness at any time of year, but it can be especially frustrating during the transition from one season to another. In this article, we will explore why we may be more susceptible to getting sick during seasonal changes and what we can do to protect ourselves from illness during these times.

Seasonal Changes and Immune System Function

One of the main reasons that we may be more susceptible to getting sick during seasonal changes is that our immune systems are affected by the changing seasons. Our immune systems rely on a variety of factors to function properly, including exposure to sunlight, temperature, and humidity. As the seasons change, these factors can change as well, which can have an impact on our immune systems.

For example, during the winter months, there is less sunlight and the temperature is colder, which can lead to a decrease in vitamin D production. Vitamin D plays an important role in our immune system, so a lack of it can make us more susceptible to getting sick. Similarly, in the summer, the heat and humidity can take a toll on our bodies, leaving us feeling dehydrated and run down, which can also make us more susceptible to illness.

Allergies and Seasonal Changes

Another reason that we may be more susceptible to getting sick during seasonal changes is that our allergies can be triggered by the changing seasons. Allergies are an overreaction of the immune system to certain substances, such as pollen, mould, or pet dander. As the seasons change, the levels of these substances in the air can also change, which can trigger an allergic reaction.

For example, during the spring, the trees and plants are blooming, which can lead to an increase in pollen levels in the air. This can trigger allergies in people who are sensitive to pollen, making them more susceptible to getting sick. Similarly, in the fall, the mould levels in the air can increase, which can trigger allergies in people who are sensitive to mould.

Preventing Illness During Seasonal Changes

While it may be difficult to completely prevent getting sick during seasonal changes, there are some steps that we can take to protect ourselves from illness.

  • Vitamin D supplements: Taking vitamin D supplements during the winter months can help to boost our immune systems and reduce our risk of getting sick.
  • Eating a balanced diet: Eating a diet that is rich in fruits and vegetables can help to boost our immune systems and protect us from illness.
  • Drinking plenty of water: Staying hydrated is important all year round, but it is especially important during the summer months when the heat and humidity can dehydrate our bodies.
  • Washing your hands frequently: Washing your hands frequently can help to reduce the spread of germs and protect you from getting sick.
  • Getting enough sleep: Getting enough sleep is important for our overall health, and it can also help to boost our immune systems and protect us from illness.
Conclusion

Getting sick during seasonal changes can be frustrating, but it is a common occurrence for many people. Understanding why we may be more susceptible to getting sick during these times and taking steps to protect ourselves can help to reduce our risk of illness. By boosting our immune systems, staying hydrated, and taking care of ourselves, we can reduce our risk of getting sick during seasonal changes and enjoy the change of seasons.
