As spring slowly arrives with its fresh bloom and warmer days, this seasonal shift can significantly impact on your health. Rising pollen levels and fluctuating temperatures can challenge the immune system, by triggering allergies or increasing the risk of infections, making it more important to take proactive steps to manage the effects of the season. In this article, you’ll find practical tips on how to boost your immunity this spring and keep your body strong throughout the season.
Maintain a balanced, nutrient-rich diet
No single nutrient or food can independently boost your immunity. Maintaining a balanced, varied diet with plenty of fruits, vegetables and lean proteins is essential to ensure your immune system functions properly. Foods rich in essential vitamins and minerals such as vitamins A, B6, B12, C, folate, and iron play a crucial role in supporting your body’s natural defences. Avoiding ultra-processed and high sugar foods will also help prevent the suppression of the immune system.
Healthline suggests incorporating certain foods into your diet to keep your immune system strong. Some examples include:
- Citrus fruits like oranges and grapefruit are high in vitamin C, which helps increase the production of white blood cells and fight off infections.
- Yogurt, particularly plain, is a great source of vitamin D and probiotics, which can support gut health and regulate the immune system.
- Poultry, such as chicken and turkey, is rich in vitamin B6. Vitamin B6 is vital in the production of new red blood cells, as well as supporting many biochemical reactions that help the body’s immune system function efficiently.
Besides, don’t forget to stay hydrated as drinking enough water can help flush out toxins and support a healthy immune system.
Stay active
Regular physical exercise also boosts immunity. found that exercising at moderate intensity for just 15 minutes increases levels of natural killer (NK) cells – a type of white blood cell that protects the body against infections.
The Australian Government recommends doing up to 5 hours per week of moderate intensity activity such as brisk walking, swimming, or up to 2.5 hours per week of high intensity activity like jogging or cycling. It’s also a good idea to start incorporating strength training, for instance, weightlifting, push-ups or pull-ups, into your daily exercise routine. Strength training can increase muscle strength and endurance, as well as lower the risk of chronic diseases, which helps the body more effectively defend against seasonal health challenges.
Get enough sleep
Good quality sleep allows your immune system to replenish and strengthen. Getting a minimum of 7-hours of sleep each night will increase the efficiency of T cells, which play an important role in attacking viruses and other pathogens. On the other hand, sleep deprivation can reduce the production of cytokines, thus weakening the immune system, leading to higher inflammation levels and increasing risk for chronic diseases.
Here are a few tips for a good night’s sleep:
- Invest in a comfortable mattress and pillows
- Avoid consuming caffeine or alcohol late in the hours leading up to bedtime
- Avoid scrolling through the phone at least 1 hour before bed
- Engage in a calming activity, for example, reading or meditation
- Regular exercises can promote better sleep
Manage stress effectively
According to Siddharth (2025), chronic stress could not only affect your mental health but also makes you more susceptible to infections and other health problems. It triggers high levels of cortisol released in your body for extended periods, which can weaken your immune system over time. Therefore, managing stress effectively is crucial to maintain a strong immune system.
Practicing mindfulness or meditation for 5 to 10 minutes a day is a great way to help your mind and body relax. Allowing yourself to take breaks on a busy day, whether it’s stepping outside for fresh air or simply closing your eyes for a minute can refresh your mind and prevent burning out. Staying connected with friends and family can also play a powerful role in providing emotional support and relieving stress.
