Changing Weather Means High Risk Of Contracting Infections; Tips For Prevention

After long unbearable summer months comes the relief of a cold breeze. But, with this breeze come new diseases and infections. This weather change causes change in the daylight hours, temperature and humidity which can increase our risk of various diseases. According to National Library of Medicine, one of the main culprits are infections. Understanding the impact of weather changes on our susceptibility to infections can help us better avoid them. Let's understand how changing weather increases our risk of contracting infections and what preventive tips can help you stay safe.

How does changing weather increase infection risk?

• Sudden change in the weather can affect your immune response. This happens because the cold weather constricts your blood vessels which in response reduces the effectiveness of your immune cells which leads to viruses thriving.
• The weather causes reduction in humidity levels. Less humidity causes nasal passages to dry out which can trap viruses and bacteria and increase risk of infection.
• Many people experience allergies like pollen or dust which can increase risk of infections as it irritates respiratory passages.
• Lesser daylight hours reduce your exposure to vitamin D. Vitamin D plays a huge role in supporting proper functioning of your immune system.

Now that you understand what makes you more susceptible to infections as the weather changes, let's discuss what tips can help you stay safe.
