Clod and Flu image
There are several reasons why people may experience fever during the winter. Some of the most common causes include:
- Cold and Flu: Both colds and the flu are common during the winter months and can cause fever, chills, body aches, and other symptoms.
- Respiratory Infections: Winter weather can lead to an increase in respiratory infections such as pneumonia, bronchitis, and sinusitis, which can cause fever, cough, and difficulty breathing.
- Seasonal allergies: Cold weather can also trigger seasonal allergies, which can cause fever-like symptoms, such as a runny nose, sneezing, and itchy eyes.
- Hypothermia: If a person is exposed to cold weather for a long time, it can cause their body temperature to drop, resulting in hypothermia and fever.
- Vitamin D deficiency: Less sunlight in the winter can cause a deficiency in Vitamin D which is important for immune function, leading to increase in susceptibility to infections.
It is best to check with a doctor if you have a fever and any other symptoms to determine the cause and receive appropriate treatment.
