Doctor Reminds of Simple Rules to Avoid Getting Sick During Holidays
As the colder months approach, keeping the immune system strong becomes more important than ever. According to medical experts, everyday habits play a key role in how well the body fights off infections.
Dr Susanna Wiley, a general practitioner and medical advisor for IQdoctor in Germany, highlights that lifestyle choices directly affect immune performance. Small changes can make a big difference in staying healthy.
A balanced diet forms the foundation of good immune health. Fruits, vegetables, whole grains, and lean proteins provide essential nutrients. Vitamins C and D, along with zinc, are especially important for supporting the body’s defences.
Hydration also matters—dehydration weakens the immune response. Drinking enough water helps maintain the body’s natural barriers against illness. Sleep and stress management are just as vital. Chronic exhaustion and poor sleep increase the risk of falling ill. Dr Wiley advises prioritising sleep hygiene, taking regular breaks, and allowing time for recovery. High stress levels further lower resistance, so relaxation techniques can help. Limiting alcohol is another key step. Excessive drinking disrupts sleep and reduces the body’s ability to fight infections. While no pill can stop a cold once symptoms appear, prevention remains the best strategy. For flu protection, vaccination is the most effective measure. It significantly lowers the chance of infection and serious complications.
Strengthening the immune system requires consistent effort in diet, sleep, and stress control. Avoiding alcohol and staying hydrated also improve the body’s ability to resist illness. With these steps, people can reduce their risk of colds and flu during the winter season.
