When winter arrives, cold weather, reduced sunlight, and spending too much time indoors directly affect human health. During this period, the immune system weakens, making the body more susceptible to various viruses and bacteria. Seasonal illnesses are especially common among children and the elderly.
The role of the immune system
Immunity is the body's protective shield. A strong immune system protects a person from diseases by fighting viruses and bacteria. However, fatigue, malnutrition, stress, and lack of sleep weaken this system. In this case, a person can become more susceptible to diseases such as flu, colds, and bronchitis.
Symptoms of immune deficiency
When the body's defense mechanism weakens, certain signals appear in the body. These include symptoms such as frequent illness and prolonged illness, constant fatigue, weakness, pale skin, hair loss, brittle nails, decreased appetite in children, and sleep disturbances.
Immune-boosting medications and vitamins
During the winter months, taking immune-boosting medications and vitamin complexes with a doctor’s guidance can help strengthen the body’s defenses. Supplements such as vitamin C, vitamin D, zinc, and Omega-3 are especially beneficial for immunity. Additionally, when used correctly, various immune-boosting medications available on the market can help prevent flu and other seasonal illnesses. However, it is essential to consult a doctor before starting any medication.
Boosting immunity in children
One of the most vulnerable groups during the cold months is children. A weak immune system is one of the main reasons they often fall ill, so it is important to pay attention to their daily nutrition to strengthen immunity. Foods that help boost immunity in children include:
- Fruits rich in vitamin C, such as oranges, tangerines, and kiwi
- Fish and eggs – a source of vitamin D and protein
- Dairy products – rich in calcium and probiotics
- Honey and nuts – natural remedies for energy and immune support
In addition, it is important for children to spend time outdoors, get enough sleep, and stay away from stress.
Ways to prevent diseases in winter
Simple but effective steps are enough to protect yourself from seasonal illnesses. Washing your hands frequently, following hygiene rules, regularly ventilating indoor spaces, eating a balanced diet, drinking enough water throughout the day, dressing appropriately for cold weather, and getting vaccinated under your doctor’s guidance can help protect you from illnesses during the winter months.
