Why Some People Get Sick More Easily Than Others And What To Do About It By Dr Manuel Abreu

Staving off diseases is both an individual and collective undertaking. Have you ever noticed how some people seem to catch colds more frequently than others? While it’s common to surmise that a robust immune system can combat illnesses more efficiently, understanding the underlying factors that contribute to our susceptibility to infections is crucial. This blog post will delve into the reasons why some individuals fall sick more easily than others and share tips on how to stay healthy and prevent illnesses.

Factors Affecting Susceptibility To Illness

  • Genetics: Our genes significantly shape our immune systems. Some people inherit a stronger immunity, while others have a more vulnerable genetic predisposition, leading to a higher likelihood of acquiring infections.
  • Age: Young children and the elderly are more prone to falling ill. Children’s immune systems are still developing, while older adults experience a natural decline in immunity as they age.
  • Stress: High levels of stress can impair the immune system’s functionality, resulting in increased vulnerability to infections. Chronic stress can affect hormone levels and disrupt sleep, preventing the body from repairing itself effectively.
  • Poor nutrition: An unhealthy diet lacking essential vitamins and minerals can weaken the immune system. Good nutrition is key to maintaining a well-functioning body that can respond effectively to infectious agents.
  • Lack of sleep: Inadequate sleep can have adverse effects on immunity. Sleeping allows the body to repair and rejuvenate itself, contributing to a robust defense mechanism.
  • Underlying health conditions: Certain medical conditions, such as diabetes, asthma, and autoimmune disorders, can make people more susceptible to illnesses, as they may diminish the effectiveness of the immune system.

Tips For Staying Healthy And Preventing Illnesses

Maintain A Healthy Diet

Nourishing your body with essential nutrients is vital in keeping the immune system functioning optimally, says Dr Manuel Abreu. Incorporate fruits, vegetables, lean proteins, and whole grains into your daily diet.

Get Sufficient Sleep

Prioritize sleep, ensuring that you get an adequate amount each night. A general guideline for adults is to aim for 7 to 9 hours of sleep daily.

Manage Stress Levels

Practice relaxation techniques such as deep breathing, meditation, or yoga to help cope with stress and maintain mental well-being.

Stay Up-To-Date With Vaccinations

This is crucial for preventing and reducing the spread of infectious diseases. Ensure that you receive recommended vaccinations for your age and region.

Wash Your Hands Regularly

Frequent handwashing with soap and water, especially before eating and after potential contamination, can significantly reduce the transmission of germs, as Dr Manuel Abreu would explain.

Maintain Good Hygiene

According to Dr Manuel Abreu,keep your living space clean and practice coughing or sneezing into your elbow or a tissue to limit the spread of germs.


By understanding the factors that play a role in disease susceptibility and taking active steps to promote health, it’s possible to reduce the risk of contracting illnesses. Focusing on preventive measures, such as maintaining a healthy lifestyle, practicing good hygiene, and managing stress, pays dividends in achieving optimal well-being and safeguarding against infections. It’s about time we took control of our health and minimized our chances of getting sick.
