When the weather is cold outside, people tend to spend more time indoors. This makes it easier for viruses to spread from one person to another. The most common cold/flu viruses survive better when the humidity is low, which is during the colder months. Cold weather may make the inside lining of your nose drier and more vulnerable to viral infection. If you’re going to cover anything when going out in cold weather, it’s perhaps best to cover your nose/mouth. Lack of sunlight helps the common cold/flu viruses survive longer. The winter months typically have less sunlight than the spring/summer months.
As winter is fast approaching don’t get stuck with a cold. Here are seven ways to help prevent a cold this season.
1) Drink water
Water flushes your system, helping you stay hydrated and healthy.
2) Avoid touching your face.
The cold and flu viruses easily enter through the mucous membranes of your body such as the eyes, nose or mouth.
3) Wash your hands
Most cold and flu viruses are spread by direct contact such as through a handshake or by sneezing into your hand, then touching an object, and thus infecting it.
Exercise (especially aerobic exercise) increases your heart rate, rate of breathing and core body temperature. Collectively, this can help boost the white blood cell count of your body (white blood cells fight off infections)
5) Eat your fruit and veg
Foods that come from plants (especially dark green, red and yellow types) are rich in antioxidants that can help boost your immune system.
6) Minimise alcohol
Alcohol has been shown to suppress your immune system. Additionally alcohol can dehydrate your body.
7) Don’t over-train
While exercise is good, it can be too much of a good thing. Ensure you incorporate adequate recovery, rest and relaxation into your training programme to keep your immune system strong.
