As winter settles in, so does the annual surge in colds and flu. During this time of the year, it is more important than ever to take the proper steps to protect your health. While nothing can guarantee complete immunity, these practical tips can greatly decrease your risk of infection and strengthen your immunity during the colder months.
The best way to support your body’s natural defence against sickness is to start with a balanced, nutrient-rich diet. Make sure that you are eating plenty of colourful fruits and vegetables, as this will ensure that you are getting the vital vitamins, minerals and antioxidants required to support a healthy immune system. Focus on foods rich in vitamin C, such as berries, broccoli, parsley, kiwi and broccoli. Vitamin A from carrots and sweet potatoes, vitamin E from nuts and seeds, and zinc from lean meat, legumes, pumpkin seeds and seafood will also help immensely.
If you are not getting enough sunlight during winter, your vitamin D levels may drop, which can increase your risk of infection. Include vitamin D-rich foods such as salmon and mushrooms in your diet, and if you spend most of your time indoors, speak to your healthcare provider about whether a vitamin D supplement may be right for you.
Staying hydrated is particularly important during the winter months. Indoor heating can dry out the airways, and non-sugary fluids such as water and herbal teas will help prevent congestion by thinning out mucus and regulating your body’s temperature.
Getting good quality sleep is one of the most effective ways to strengthen immunity. Try to aim for at least seven to nine hours of sleep each night. During sleep, the body repairs tissues and produces immune cells that help fight infections. Poor sleep can leave you more vulnerable to catching colds and flu, so prioritize rest and recovery.
Regular exercise will help your immune system thrive. Walking, cycling, swimming and weight lifting improves your circulation and helps immune cells move efficiently throughout the body. Aim for 2 to 3 hours of moderate exercise each week, while allowing adequate recovery between workouts.
Managing stress is equally important. Stress increases cortisol levels, which can negatively impact immune function over time. Make time for activities that help you relax. Meditation, deep breathing or reading can greatly benefit your mental and physical wellbeing.
Practicing good hygiene is one of the simplest and most effective ways to prevent sickness. Wash your hands regularly with soap and water for at least 20 seconds, especially after being in public places. Avoid touching your eyes, nose, and mouth with unwashed hands, and disinfect frequently touched surfaces such as phones, keyboards, and door handles.
Finally, avoid smoking and limit your alcohol intake.
It’s impossible to eliminate the risk of infection entirely, but by combining the tips outlined above, you can drastically improve your resilience to the season’s bugs and ailments. Small, consistent habits can go a long way toward helping you stay healthy throughout the year.
