Can you catch a cold before it even happens? It’s a question many of us are asking ourselves as we approach sickness season. Demetre Skliris, MD, a family medicine physician with Avera Medical Group McGreevy, offered some insight and tips to help you stay ahead of viruses and germs and stay healthy this season.
Can taking immune-boosting medicines or vitamins help prevent illness?
Vitamin C is the most common treatment for the common cold, but it doesn’t prevent the disease. It’s not all bad news, however. The National Institutes of Health has research showing that taking vitamin C can increase antioxidant levels in the blood, helping to reduce inflammation. Immune-boosting supplements are commonly taken before important events or travel, but they’re more of a placebo effect than a true preventative.
Do I need supplements or boosters?
Nutrients like B12 and Vitamin D are important for strong energy and help boost your immune system, but they only help if you’re deficient in the first place. Vitamin supplements are just that – supplements. They shouldn’t be taken in large amounts, as they can stop your body from naturally producing/absorbing the vitamin, causing digestive upset and deficiencies.
How can you boost your immune system naturally?
- Eat a healthy diet: A balanced diet that includes fresh fruits and vegetables will give you all the vitamins you need and strengthen your immune system.
- Get some exercise. When you get up and move, your body naturally boosts your immunity. It doesn’t have to be a lot of exercise either — 30 minutes of consistent walking, cycling, or weightlifting can have a big impact on your health.
- Prioritize bedtime. Even just one night of restricted sleep (less than four hours) can suppress the immune system and increase inflammation. Maintaining this habit will also help you avoid insomnia and other problems falling asleep.
What else can you do to prevent illness?
Make sure you have a primary care doctor. Having a primary care doctor and regular checkups will help you keep track of your vitamin D levels and identify any deficiencies. Regular checkups will also help you stay up to date on vaccinations that help prevent the spread of diseases like the flu.
