Genetics, high stress levels, and your environment may explain why you get sick so often. Even if you're generally healthy, it's always possible to get sick. How often you get sick as a healthy person depends on how your body functions. You have different types of immunity, which affect your likelihood of getting sick.
Your gut needs time to adjust
Changes to diet can affect your gut flora. High-sugar foods, for instance, allow certain kinds of intestinal bacteria to flourish, while fruits and vegetables feed other types of bacteria.
Your immunity is determined by several factors. Genetics play a large role, said Paolo Bofetta, MD, professor of hematology and medical oncology at the Icahn School of Medicine at Mount Sinai. "Immunological genes are many and complex, and your immune response depends on their combined performance," Dr.
But, for some, getting sick frequently is the norm. In fact, most people get sick with a cold or flu multiple times in a year, experts tell TODAY.com. For most adults, it's normal to get somewhere between one and three colds per year, Dr.
Frequent colds can actually indicate an underlying issue with your sinuses. Sinus problems can cause congestion and inflammation in the nasal passages, making it easier for viruses to take hold and leading to more frequent respiratory infections.
Adults average about 2 to 4 colds a year, although the range varies widely. Women, especially those aged 20 to 30 years, have more colds than men, possibly because of their closer contact with children. On average, people older than age 60 have fewer than one cold a year.
You're Overexposed to the Cold Virus
There are over 200 known viruses that can cause the common cold. So even if you've had a cold before, your immune system probably hasn't built up defenses against every virus strain that can lead to a cold. Another reason could be that you're around a lot of people who are sick.
Nausea after eating and other gastrointestinal problems may occur when an organ within the digestive system stops functioning properly. For example, gastroesophageal disease (GERD) occurs when the ring of muscle between the esophagus and stomach malfunctions, causing stomach acid to enter the esophagus.
"Macronutrient composition is very important," says Arrindell. "When nutritious, filling macronutrients are missing, you're not likely to feel satisfied for very long, meaning you're more likely to get hungry again shortly after."
"Fat, fiber and protein slow digestion and your body may need time to adjust to these changes. A little gas, bloating or discomfort is normal and natural; most people experience these and it's not necessarily a sign of an intolerance or food sensitivity."
In short bursts, our stress response has evolved as a survival mechanism to help us be more alert in fight or flight situations. But when stress is chronic, it weakens the immune system and makes us more vulnerable to illnesses such as the common cold, flu and COVID.
Well, maybe not a total reset, but at least a mild refresh. The science suggests that, if you can do it, a prolonged fast for 2-3 days or longer may induce your body to clean out some old immune cells and switch on production of new ones.
Although many people take Emergen-C to prevent or shorten a cold, the scientific evidence showing it works is minimal. There's also mixed research about vitamin C's effectiveness in preventing or treating colds in the general population. If you still decide to take Emergen-C, keep it to one serving daily.
Blood tests.
Blood tests can determine if you have typical levels of infection-fighting proteins (immunoglobulins) in your blood and measure the levels of blood cells and immune system cells. Having numbers of certain cells in your blood that are outside of the standard range can indicate an immune system defect.
Ginger tea. Whether as a tea or infused in water, ginger is an ideal go-to when the weather cools. Ginger is another food or spice that has been used in traditional medicine for centuries. Modern science supports its anti-inflammatory and, anti-oxidative benefits, which may help support your immune system.
The resilience built in youth gradually depletes until around 50 years of age, when the risk of infection and more serious outcomes starts to become more and more obvious.

Signs of a strong immune system can include eating a varied diet, drinking enough water and sleeping well. However, whilst many might assume that falling ill isn't a sure sign of strong immunity, how well you recover after being ill can be a better indicator of how well your immune system is working.
For example: lack of hand washing, sharing utensils, not using tissues, and disposing of them. Your environment – dry air, exposure to smoke, touching contaminated surfaces. Lack of sleep. Sleep releases proteins and infection-fighting antibodies to help combat inflammations and infections.
