If you wake up with classic cold symptoms like a stuffy nose and sore throat multiple times a year, that's actually completely normal. As it turns out, some people are just primed to get colds more easily and frequently than others, experts

Even if you're generally healthy, there's always the possibility of getting sick. However, how often you get sick as a healthy person depends on how your body functions. Research suggests that, on average, each individual picks up around 200 colds in their lifetime. According to science, there isn't one (yet). It is possible that some people may appear to suffer more than others with various ailments. Are you one of those unlucky people who pick up every single nasty cold on the block?, mysteriously it all depends on your immune responses

But some people seemingly never get ill.  Researchers are exploring why some people are more susceptible to cold and flu viruses. While we don't have all the answers, we believe that your environment, genetics and immune system play a key role in determining your risk for these illnesses.”'Some of us inherit a set of immune system genes that are particularly good at dealing with one particular virus. All it means is that you would deal with a particular flu virus better than others. There is an inherent diversity in how our immune systems respond to different diseases and that diversity is essential to how we survive with the particular disease.

Possible reasons may be due to our immune system which in turn regulated by many other factors such as, our lifestyle and genetics. Having bad diet rich in saturated fats, sugar, and salt, smoking and drinking alcohol, too much or not enough physical exercise, bad hygiene (especially not washing your hands well), stress and lack of having fun and relaxation have a negative impact on our immune system. Nevertheless our genetic make-up determines and immune deficiencies are an important contributory factor in why some people contract more colds than others. A genetic weakness in the lungs, such as cystic fibrosis for example, can put people at risk if they just catch a common cold.

So can allergies, lack of sleep, stress, not eating properly, or being around someone who smokes. And smokers are more likely to catch colds than people who don't smoke. Their symptoms will probably be worse, last longer, and be more likely to lead to bronchitis or even pneumonia.

For Not to Get Sick Often

Improve the Immunity. It is better to adopt A healthy lifestyle. The immune system is the body’s way of protecting itself from infection and disease; it fights everything from cold and flu viruses to serious conditions such as cancer.

Our immune systems are complex and influenced by many factors. Some additional ways you can strengthen your immune system are eating well, being physically active, maintaining a healthy weight, getting enough sleep, not smoking, and avoiding excessive alcohol use.

Although science might not support the concept of superhuman health (at least not yet), it is well-known and extensively documented that certain lifestyle choices can help boost your immunity and give you a better chance of fighting off the cold that's been making it's way around the office.

Early exposure and the immune system

It might be a bit late for this if you're an adult, but if you expose your children to certain levels of bacteria and viruses as they grow up, the more resilient their immune systems will become later in life. It means they might be less likely to succumb to certain allergies.

The other major problem is nowadays is giving birth by cesarean section. This influences the baby’s immune health. They suffer up to four times more from breathing problems in the first days of life compared to vaginal births

Exercise and the immune system

Evidence carried out by Harvard Medical School suggests that regular exercise boosts immunity and improves circulation – not to mention all the other wonderful things it can do for both your mental and physical well-being, so get moving. In fact, I mentioned in detail in my Book “Exercise For Health Beauty”

The recommended amount of exercise in order to achieve optimal health stands at 150 minutes of moderate aerobic activity a week (that's 30 minutes a day for five days), alongside two sessions of strength exercises.

The importance of sleep quality and health

Sleep gets 4th important place in essential for life.  It has been proven to have a huge impact on the immune system. Indeed, it was found that our chances of catching a cold are up to four and a half times greater in people who only manage five and a half hours of shut-eye per night, compared to those who achieve the recommended seven hours.

 Link between stress and illness

 It's been well documented that stress is bad for mental and physical well-being, Stress is the 'best-established link' in terms of how lifestyle impacts the immune system. Partially, this is because chronic or long-term stress produces cortisol. In the short term, cortisol helps to fight infection but when its levels are continuously high, it can have a negative effect, suppressing and weakening the immune response towards potential viruses or illnesses. In other words, fight off that nasty cold
