With the increase in several respiratory tract infection cases towards the end of 2023 due to various factors such as bacteria, viruses, and allergic reactions, it is crucial for us to begin preventing them by cleansing the nose cavity with saline spray.

Respiratory tract infections involve inflammation in the respiratory system caused by viruses, bacteria, or fungi. Symptoms include a runny nose, cough, sore throat, and difficulty breathing. Prevention involves maintaining cleanliness, avoiding contact with sick individuals, and bolstering the immune system. If symptoms are severe or prolonged, immediate medical consultation is advised.

Due to increase in respiratory infection issue worldwide, such as the rising cases of COVID-19 in Singapore and undiagnosed pneumonia in China, maintaining respiratory health becomes a crucial step. Ensuring hygiene, particularly in the nasal cavity as the primary respiratory entry point, is vital.

Preserving respiratory hygiene, particularly in the nasal cavity hygiene, effect significant health benefits. The nose filters the air we breathe, maintains air moisture into the lungs, and aids in fighting infections by trapping harmful particles. Maintaining nasal hygiene by regular handwashing, gentle nasal cleaning, and using saline sprays helps retain nasal cleanliness and moisture, preventing irritation or infection while improving respiratory health.

The benefits of saline spray include:

  1. Removing allergens, pollutants, and bacteria from the nasal cavity
  2. Enhancing the sensitivity of the sense of smell
  3. Boosting nasal cilia activity for efficient mucosal layer transportation in cleansing impurities
  4. Improving nasal congestion by assisting in dissolving nasal mucus

One of the latest products from South Korea, Luca V-Defense Nasal Spray, containing Lambda Carrageenan from algae known for its natural antibacterial and antiviral properties, protects the nasal cavity's mucosal layer from viral, bacterial, and allergen attacks.

With the antibacterial and antiviral layer from Lambda Carrageenan lasting 4-8 hours, preventing bacteria, viruses, and allergens from infecting the nasal mucosal layer, this product serves as a preventive measure against respiratory tract infections.

Respiratory infections pose a serious health problem and can lead to dangerous complications if not promptly and accurately treated. In Indonesia, like elsewhere globally, undiagnosed pneumonia can become a public health concern.
