Experiencing body aches is a common symptom when you're feeling unwell. This discomfort is your body's way of signalling that something is wrong, and it's usually a result of the body working to heal itself in response to stress, fatigue, or an underlying illness or medical condition. When you get sick, your immune system kicks into high gear to combat the invading germs, and this immune response often results in inflammation and muscle soreness. This inflammation can cause pain that feels similar to mild arthritis, and it can affect any part of your body.

What You'll Learn
Inflammation caused by the immune system fighting infection
When you get sick, your body releases white blood cells to fight off the infection. This reaction causes inflammation, which can leave your muscles feeling achy. The harder your body works to fight the infection, the more severely your body might ache. This inflammation caused by the immune system's response to an infection can result in muscle soreness, also known as myalgia, which can affect any part of your body. Myalgia can range from mild discomfort to severe pain, and it is often accompanied by other symptoms such as fever, chills, headache, sore throat, or cough.
Myalgia is a common symptom of viral infections, such as the flu, COVID-19, or the common cold, and it can also be caused by bacterial infections. When infected by a virus, the body's immune system responds by sending antibodies to attack the virus and prevent its spread. This immune response can lead to muscle inflammation and weakness, called myositis, or joint and muscle pain, called myalgia. Inflammation can cause pain similar to mild arthritis, and it is important to understand the root cause of your body aches to find relief.
To minimize the discomfort of myalgia, it is recommended to take over-the-counter medications such as acetaminophen or ibuprofen, which are non-steroidal anti-inflammatory drugs (NSAIDs) that reduce inflammation and relieve pain. Additionally, staying hydrated is crucial, as it helps your body fight the infection. Drinking plenty of clear liquids, such as water, tea, broth, or electrolyte drinks, will help replenish fluids lost through symptoms such as sweating, vomiting, or diarrhea.
Rest is also essential when experiencing muscle aches due to illness. Getting enough sleep will help your body recover faster, reduce inflammation, and boost your immune system. Gentle exercises, such as stretching, can also be beneficial in preventing stiffness and alleviating muscle aches. Heat can further help loosen muscles and provide relief, such as through a warm shower or bath with lukewarm water.

Dehydration caused by flu symptoms
Dehydration is a common issue when experiencing flu symptoms. The flu, also known as influenza, is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. Flu symptoms usually come on suddenly, and the illness can cause mild to severe health issues, and sometimes even lead to death.
The flu often causes vomiting, diarrhea, and sweating, which can lead to dehydration. Dehydration occurs when the body does not have enough water and other fluids, which is especially dangerous for infants, young children, and older adults. Diarrhea and vomiting can cause a significant loss of water and minerals, or electrolytes, in a short amount of time. Electrolytes such as potassium and sodium help carry electrical signals from cell to cell, and an imbalance can cause muscles to tighten or shorten.
Additionally, people with a cold or sore throat are less likely to feel like eating or drinking, which can also lead to dehydration. Flu symptoms can also cause a loss of appetite, making it difficult to stay hydrated through food sources. It is important to drink plenty of water, broth, tea, or electrolyte drinks when experiencing flu symptoms. Soup is also a great way to stay hydrated and provide your body with nutrients, especially if you are struggling to eat solid foods.
The best way to prevent dehydration caused by the flu is to avoid getting the flu in the first place. You can lower your risk of infection by washing your hands frequently with soap and warm water, and keeping germs from spreading. If you do get the flu, it is important to drink fluids as soon as you start feeling unwell to prevent or reverse mild or moderate dehydration.

Stress and tension
While it is not explicitly stated that stress and tension are the cause of muscle aches when you are sick, stress can have a significant physical impact on the body. This is because stress creates tension in the body, causing muscles to feel stiff. Stress can also cause inflammation throughout the body, which is often the cause of muscle aches when sick.
When you are sick, your body is working to heal itself, and this process can cause muscle inflammation and weakness, or myositis, and joint and muscle pain, or myalgia. Myalgia can affect any part of your body and can be quite annoying, especially if you are already dealing with various other symptoms. Myalgia can range from mild discomfort to severe pain, but it is typically mild and goes away once the underlying issue is resolved. Understanding the root cause of your body aches is key to finding relief.
Stress can also lead to chronic fatigue syndrome (CFS), which may cause body aches, as well as weakness and exhaustion. Staying hydrated is key to feeling well when experiencing CFS. Drinking plenty of clear liquids will help replenish any fluids lost through sweating, vomiting, or diarrhea and help your body fight infection. Water, tea, electrolyte drinks, broth, and non-sugary sports drinks are all great options to help keep you hydrated while you recover.
To alleviate muscle aches caused by stress and tension, gentle movements such as stretching can prevent stiffness and provide relief. Additionally, non-prescription pain relievers such as acetaminophen or ibuprofen can help alleviate muscle aches. It is best to consult a healthcare provider to determine the best medication for your specific symptoms.

Autoimmune disorders
When you are sick, your body releases white blood cells to fight off the infection. This reaction causes inflammation, which can leave your muscles feeling achy. This is a sign that your body is fighting off the illness. However, sometimes, muscle aches can be indicative of an underlying autoimmune disorder.
Myositis, for example, is a rare autoimmune disease that inflames and weakens muscle fibres. It occurs when the body's immune system attacks healthy muscle tissue, resulting in inflammation, swelling, pain, and eventual weakness. Myositis can be triggered by various factors, including viral infections, certain drugs, and genetic predispositions. It often affects the muscles in the upper arms and thighs, causing difficulty in performing simple movements. The disease can also impact lung tissue, leading to respiratory issues, and the digestive tract, causing swallowing difficulties.
Polymyositis is a form of myositis that affects muscles throughout the body, causing irritation, inflammation, and weakness. It can lead to severe complications if left untreated, including respiratory failure, malnutrition, and weight loss. Polymyositis may be linked to a virus or an autoimmune reaction, although the exact cause is unknown.
Another related condition is dermatomyositis, which involves skin symptoms in addition to muscle inflammation and weakness. People with myositis may also have other autoimmune conditions, such as lupus, Sjogren's syndrome, scleroderma, or rheumatoid arthritis. These disorders can cause joint pain and stiffness, as well as photosensitivity, requiring diligent sunscreen use.
Diagnosing myositis and its variants can be challenging due to their rarity and similarities to other autoimmune diseases. Doctors employ various tests, including blood tests, muscle biopsies, and imaging techniques, to confirm the presence of specific muscle enzymes, autoantibodies, and inflammation. While there is no cure for these conditions, proper diagnosis and management of symptoms are crucial to prevent severe complications and maintain quality of life.

Poor sleep
Research indicates that insufficient sleep and low-quality sleep increase the risk of developing widespread pain, particularly as we age. One three-year study found that non-refreshing sleep was the factor most strongly linked with the development of pain that was not linked to specific sources. Another study found that insomnia is likely to cause "musculoskeletal pain" and increased muscle pain in normal, healthy people.
The link between poor sleep and muscle aches may be due to changes in the nervous system. Sleep deprivation can cause oversensitivity, lowering our pain tolerance and causing inflammation in the body, which often results in muscle aches and pains. This can also exacerbate inflammatory conditions such as arthritis.
Additionally, a lack of sleep can impair athletic performance and increase the risk of muscle and joint injuries. This means that even everyday activities, such as running to catch a bus, can result in injury and pain.
