Stay Healthy on Your Next Flight: Expert Tips to Avoid Getting Sick

Millions of people travel by air every year, and many experience illness afterward. Dr. Eric Berg, a renowned health expert, offers insight into this common problem. He explains that jet lag, the recycled air quality, and stress-induced cortisol all contribute to weakened immunity during and after flights. "Flying increases cortisol, which is an immunosuppressant," says Dr. Berg. His recommendation? Taking a significant dose of Vitamin D3 before flying. This simple step can significantly boost the immune system, helping travelers stay healthy despite the challenges of air travel. By following Dr. Berg's advice, travelers can enjoy their journeys with greater peace of mind.
