Why do some people go through the cold season without even a scratchy throat, while others fall ill almost immediately? Often, it comes down to small everyday habits: physical activity, fresh air, hand hygiene, and above all, quality sleep. Vitamins or sauna sessions can be a pleasant bonus. Prevention also plays an important role, including vaccination.

While it’s not always possible to avoid a cold completely, there are simple steps that can significantly reduce the risk of getting sick. Focusing on everyday habits such as movement, rest, and hygiene helps strengthen the immune system and supports the body’s natural defenses. The tips below highlight what is truly worth paying attention to.

  • Exercise and Fresh Air
    Regular physical activity and spending time outdoors support the immune system and increase resistance to infections. Even a short walk in the fresh air can help keep the body resilient.
  • Hand Hygiene
    Cold viruses are most often transmitted through hands. Frequent and proper handwashing remains one of the simplest and most effective preventive measures.
  • Quality Sleep
    Sleep is essential for a well-functioning immune system. Lack of rest weakens the body’s defenses, while sufficient, high-quality sleep helps the body fight infections more effectively.
  • Vitamins and Sauna as a Bonus
    Vitamins or sauna visits can be a useful complement to prevention, but they should not replace basic healthy habits and hygiene.
  • Prevention Through Vaccination
    Vaccination also has its place in prevention, particularly for at-risk groups and during periods of increased incidence of respiratory infections.
