It’s a chilly winter morning.
I’m standing by a reservoir in just my swim shorts, and I feel a bit out of my element. A bright sign tells me the water is a freezing 3.9°C. One of the regulars chuckles and reminds me that this isn’t just cold; it’s “ice” water swimming.
How did I end up in this situation?
I’ve been curious about ways to boost my immune system. This winter, I’ve battled through a barrage of colds, coughs, and even an upset stomach. Every time I stepped out, it seemed like another germ was waiting for me.
Our bodies are fighters, doing their best to fend off viruses and other harmful invaders. According to Professor John Tregoning from Imperial College London, every breath we take is full of bacteria and viruses. In just a minute of breathing, we can inhale between 100 and 10,000 bacteria and around 25,000 viruses! It’s a wild world of germs out there.
“You’re constantly surrounded by these pathogens,” he says. It’s a bit unsettling to think about, but it’s also a reminder of how hard our immune system works every day.
Luckily, there are many foods, supplements, and activities folks claim can help boost immunity. But can we really turn up the dial on our body’s defenses? Let’s explore some options.
Eating a balanced diet packed with fruits and vegetables can provide essential vitamins that support our immune system. Foods rich in vitamin C, like oranges and broccoli, are well-known for their immune-boosting properties. Omega-3 fatty acids found in fish and nuts can also help decrease inflammation and promote overall health.
Staying active is crucial too. Regular exercise can improve circulation and help the body fight off illnesses. Whether it’s a brisk walk or a swim in icy water, moving our bodies keeps our systems in top shape.
Hydration is just as important. Drinking enough water helps our kidneys flush out toxins and supports our immune function.
Lastly, getting adequate sleep allows our body to recover and heal. Prioritizing rest helps combat the wear and tear of daily life and keeps our immune system performing well.
So, while I may be standing at the edge of a freezing reservoir today, I’m reminded that taking care of my body is a journey—and every step, even the cold ones, is a part of it.
