As per the National Institutes of Health, flu viruses are mainly spread from coughing and sneezing through saliva droplets. Discovering early signs of flu will not only help in preventing the spread of the virus, but you can also treat the sickness before it gets worse. There are a number of early flu symptoms.
As the days become shorter, reduced sunlight can make you tired. Sudden, excessive tiredness is among the first symptoms of flu, and is frequently a warning before other associated symptoms appear. If you notice sudden, severe weakness and fatigue that interferes with your regular activities, it must be the human body preparing to fight the symptoms of flu.
Body aches and chills are also associated with early flu symptoms. Your head and legs might ache. Body aches can be accompanied by chills. Gradually, fever develops. A constant cough is indicative of an early sickness, and it can signal the arrival of flu. The flu virus might lead to a cough combined with chest tightness and wheezing. You may also cough up phlegm or mucous.
You may also have a sore throat. The throat may also swell up. At the earliest phases of flu, your throat might feel scratchy and there might be some irritation. You might also have difficulty in swallowing. Gargling helps to provide relief. Also drinking warm water, soups and tea help. As the virus progresses, the throat might start hurting more.
You might also get fever which is an indication that your body is attempting to fight off the infection. The fever can go up to 100 degrees Fahrenheit or higher. However, not everybody who has flu gets fever. You can also get stomach pain and start vomiting. Nausea and diarrhoea are also certain symptoms.
However, if you have breathing difficulties, chest pain, recurring fever, dizziness, severe dehydration and bluish lips and skin, go to a doctor immediately.
