Common cold and flu are the two types of viral infections often characterised by similar symptoms such as fever, cough, cold, runny nose and many others. While the common cold is usually milder, flu symptoms can get severe and intense and may cause conditions like pneumonia or hospitalisation.
The common cold, as the name suggests, is a commonly-occurring viral disease that no one can avoid for their whole life. Both the common cold and flu can occur any time of the year, however, the prior is more common during the winters. Also, the common cold is caused by around 200 different types of viruses while flu is caused by the influenza virus, which also causes conditions such as swine flu and bird flu.

The common cold is mainly caused by allergies, seasonal change, infections or intake of cold foods. It usually clears up in a week or 10 days without any medications. Recurring episodes of the condition can be due to a weakened immune system and unhygienic habits.
The foods we consume have a lot of impact on our body. Some foods such as cold drinks may worsen the common cold and some such as seafood and citrus fruits can help boost the immune system and tackle its symptoms effectively.

3. Daily Habits That May Increase The Risk Of Common Cold
Though common cold is not a severe condition, it can interfere with daily habits due to its irritating symptoms such as sneezing, coughing or throat pain. Experts suggest that an unhygienic lifestyle is the main cause of the common cold and thus, maintaining clean and hygienic lifestyle habits can help prevent the condition to a great extent.
This is because, in most cases, viruses spread through unhygienic places, not maintaining hand hygiene, uncooked foods, polluted areas, crowded places and physical contact with infected people.

4. Signs That Say It’s More Than Just A Common Cold
Common cold symptoms are often confused with the initial symptoms of many severe conditions such as flu, dengue fever or ebola. Due to this confusion, people often delay the treatment, which may lead to fatal medical conditions such as pneumonia.
The common cold persists for a week or 10 days while flu can take around two weeks to cure. Also, cold symptoms come slowly and are usually harmless while symptoms of flu or ebola disease come quickly and get severe within a few days.
Therefore, it is best to identify the difference between the symptoms of the common cold and other similar conditions such as flu.

Flu is a communicable influenza virus disease while asthma is a chronic non-transmissible inflammatory disease. Both conditions can cause severe respiratory conditions in humans.
Many studies have shown that people with asthma are more likely to get affected by the influenza virus compared to healthy adults, due to their weakened immune system. However, influenza vaccines can be an effective way to prevent around 59 to 78 per cent of asthma attacks.

9. Best Foods To Eat When You Have Stomach Flu

Experts suggest that during stomach flu, one must keep a check on the foods one consumes. Some foods such as banana, rice water and ice chips can help decrease the feeling of nausea, reduce stomach irritation and help fight stomach pathogens.

This plant compound is present in almost all fruits, vegetables, nuts and seeds such as blackberries, onions and red wine. However, some food items contain them in abundance.

Many fruits and vegetables contain the aforementioned nutrients, however, among them, broccoli is considered a superfood by experts as it is rich in phytochemicals such as sulforaphane, antioxidant vitamins such as vitamin C and A, and immune-system boosting minerals such as selenium, zinc and iron.
These plant chemicals can effectively help treat rhinovirus and influenza virus, those that cause the common cold and flu.
