Why Your Skin Sensitivity Increases During a Cold or Flu

During a cold or flu, you may notice that your skin becomes unusually sensitive to the touch. This reaction is not uncommon and is a natural part of your body's defense mechanism. If you experience persistent or worsening skin sensitivity, it’s essential to consult a doctor. Here’s a detailed explanation of why your skin might react this way during sickness:

Heightened State of Alertness

When your body is fighting an infection, such as a cold or flu, it goes into a heightened state of alertness. This increased alertness can manifest as heightened sensitivity in various bodily functions, including the skin. Your skin, being part of your immune system, is particularly alert and reactive during these times.

Role of the Skin in Your Immune System

Think of the skin as your first line of defense against infection. The skin contains a large number of nerve endings, which allows it to respond quickly to potential threats. While skin pain is unique and should not be confused with muscle pain, the increased activity within these nerve endings can contribute to the heightened sensitivity you might experience.

When you have a cold or flu, over-the-counter analgesics can provide some relief from the discomfort. However, persistent or worsening pain should be discussed with a healthcare professional to ensure that there are no underlying issues that need to be addressed.

Impact of Illness on Skin Strength

When your body is fighting an illness, everything in your body becomes weakened. This includes the cells in your skin, making them more susceptible to sensitivity. By the time you start feeling unwell, your body is already engaged in a battle, and one of its strategies is to increase blood flow to the skin to help deliver immune cells and antibodies more rapidly. This heightened blood flow can result in a more sensitive skin.

Multiple Factors at Play

There are several factors that contribute to the increased sensitivity during a cold or flu. When your body is run down while fighting a virus or infection, it takes a toll on your skin. Additionally, irregular eating patterns, fluctuating body temperatures, and other systemic issues can all play a role in enhancing the sensitivity of your skin.

Supporting Your Immune System

The sensitivity you feel during a cold or flu might be due to the stress placed on your immune system. Supporting your systemic immunity can help mitigate these effects. Drinking plenty of water and increasing your intake of vitamin C (aim for about 1.5 grams per day) can provide a significant boost to your immune function and help you feel better faster.

However, if the skin sensitivity persists or is accompanied by other concerning symptoms, it's important to consult a healthcare professional to ensure there isn’t a more serious underlying condition.
