Doctors share 5 ways to help increase resistance and prevent diseases during seasonal changes

Get enough sleep

Master - Specialist Doctor 1 Vo Huynh Quoc Kha, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, Facility 3, said that the immune system helps protect the body from infection. When it does not function properly, the immune system can launch an attack on the body even when there are no bacteria or cannot prevent bacteria from entering the body. Autoimmune diseases and allergies are some examples of immune disorders that can affect our bodies.

"A large body of scientific evidence has shown that sleep loss negatively affects various parts of the immune system. This can lead to the development of a variety of disorders. Insufficient sleep reduces the activity of NK cells (a type of white blood cell in the natural immune system), which play a significant role in killing cancer cells.

Eat a varied and nutritious diet

Associate Professor - Doctor Lam Vinh Nien, Head of the Department of Dietetics - Nutrition, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, said that preventive nutrition plays an important role in increasing resistance and preventing infectious diseases at the end of the year.

Eating a varied diet with all food groups, especially adding fruits and vegetables, helps increase vitamins and minerals.

"In winter, especially in cold weather areas, the body will lose less sweat through the skin, so compared to normal days, the diet should reduce salt and supplement enough water," Dr. Nien shared.

Fully vaccinated

Dr. Bach Thi Chinh, Medical Director of the VNVC Vaccination System, said that at the end of the year, the weather is often cold and humid, creating conditions for viruses and bacteria to be more active than in other seasons. In addition, the increased movement and travel of people in public places will also increase the risk of spreading infectious diseases.

In addition, some seasonal infectious diseases can affect people's health, including the elderly, pregnant women, and children. Diseases such as flu, rabies, encephalitis, meningitis, Japanese encephalitis, measles, etc. are also common during the transitional season. In addition, Covid-19 is now also starting to increase again in the world and Southeast Asian countries.

"Proactively getting vaccinated is considered a necessary step to prevent infectious diseases at the end of the year. In addition, people should wear masks, wash their hands regularly, and eat safe food with guaranteed origins to ensure their health," Dr. Chinh recommended.

Physical training

According to Dr. Quoc Kha, regular physical activity helps us feel better, sleep better and reduce anxiety. Combined with a healthy diet, physical activity has many benefits for the immune system. Studies have shown that moderate exercise for less than 60 minutes has been shown to increase the circulation of immunoglobulins, anti-inflammatory cytokines, neutrophils along with improved immune surveillance, helping to fight pathogens and cancer cells.

Gentle physical activity has many benefits for the immune system.

Avoid stress, limit alcohol and tobacco

Dr. Quoc Kha said that when stressed, the body increases cortisol secretion. Cortisol has many functions in the human body, such as regulating metabolism, inflammation and immunity. Cortisol has anti-inflammatory effects and inhibits immune responses, chronic hypercortisolemia can lead to resistance of the immune system. Studies show that individuals with higher stress levels are more likely to experience clinical symptoms during respiratory viral infections.

In addition, maintaining a healthy lifestyle and limiting alcohol and tobacco will also help avoid immune system disorders and keep the body healthier.
