A Healthy You: Flu symptoms

News

Does the flu make you feel achy, cold, hot, and just terrible all over? It could be a sign of how hard your immune system is working.

Every year, people across the US come down with the dreaded flu.

For some, it can be bad enough to send you to the hospital and sometimes it can be deadly.

For most, however, it’s several days of misery at home.

From a fever and coughing, a sore throat and muscle aches, it can seem like the virus is attacking our entire body.

That really isn’t the case, though.

Researchers at the University of Connecticut School of Medicine say the influenza virus is an infection that just goes after your respiratory tract – your nose, throat and lungs.

It binds to specific cells in your lungs’ airways, eventually creating more viral particles to invade more cells.

Your body fighting back is what causes all the coughing and sneezing.

As your T-Cells locate and attack the infection, it causes a buildup of mucus and swelling in your throat.

At the same time, other immune cells in your body are activated and enter your bloodstream to combat the virus.

This creates a chain reaction biologically — headaches, fever, fatigue, muscle soreness, and weakness.

Next time you get the flu and feel terrible, just remember it means your body is working hard for you.
