It is very common to experience mild infections during weather transitions. To naturally strengthen your immunity, focus on a balanced diet rich in fruits and vegetables, stay well-hydrated, get 7-8 hours of sleep, and practice good hand hygiene. For targeted support, supplements like Vitamin C, Vitamin D3, and Zinc can help boost your immune response. Getting an annual influenza vaccine is also highly recommended to prevent seasonal flu. For symptom relief, generic paracetamol can help manage minor body aches or fever. Please consult a doctor to get personalised advice and correct dosages for these supplements.
