Everyone falls ill occasionally, whether it’s a simple cough, cold, or flu, but some individuals seem to experience health issues more frequently than others.
Bacterial and viral infections, along with non-infectious conditions related to lifestyle, environmental elements, and genetics, all contribute to illness. A UK-based doctor has identified five major reasons why people tend to fall sick.
Dr. Sami, a qualified general practitioner, shares educational health content, expert guidance, and advice on TikTok. In a recent video on the platform, he highlighted five reasons people may consistently feel unwell.
He also explained what steps you can take to address them. The doctor explained: “Do you keep getting ill more than the average person should do?
“It’s not just bad luck. These are the top five reasons why people regularly get ill.”
1. Not enough sleep
Dr. Sami pointed out that research shows getting fewer than seven hours of sleep can triple your chances of catching colds and other viral infections, emphasizing that your immune system “requires sleep just as much as you do.” According to the Mayo Clinic, individuals lacking quality or sufficient sleep are more prone to illness following exposure to viruses, such as the common cold, and insufficient sleep can hamper recovery when sick.
2. Stress
The GP’s next point involved stress: “Chronic stress keeps cortisol levels high, and cortisol suppresses white blood cells, the cells responsible for fighting infection.” Cortisol, a hormone produced during stress, weakens white blood cells over time, making one more vulnerable to viruses like the common cold and cold sores, as noted by the Cleveland Clinic.
3. Poor diet
While many strive for a healthy diet, consuming nutritious food and drinks, the UK doctor mentioned that the majority do not intake the recommended five daily portions of fruits and vegetables. He called this a “problem” because nutrients like vitamin C and zinc are essential for a robust immune system. Dr. Sami added: “It’s also important to get outside and enjoy some sunshine since vitamin D is crucial for a strong immune system.”
4. Environment
It’s widely recognised that certain environments increase your likelihood of falling ill, particularly if you’re employed in healthcare, education, childcare or regularly commute by bus or train, as highlighted by the medical expert. He clarified that you will be “exposed to more bugs than the average person.”
The doctor suggests consistently washing your hands and sanitising frequently-touched surfaces, such as door handles and handrails.
5. Underlying health conditions
Dr Sami observed that underlying health conditions, including anaemia, thyroid disorders and digestive or liver complications can leave you feeling unwell. He recommends consulting with your GP if you believe you may have any of these conditions.
