If we are feeling under pressure, one thing we don’t need to worry about right now is having the perfect nutrition.
When there is interruption, it can often impact every aspect of our lives. During these times, it is natural to look for ways to control our environment and protect our health – but with the media flooded with health advice and tips on boosting immunity it can be confusing to know who to trust and follow. While it is certainly true that good nutrition and a healthy gut are essential for immunity, it is also important to remember that what we eat today, or this week will not be what determines our risk of being unwell. Humans have four types of immunity.
Innate or Natural Immunity
This refers to the non-specific immunity which is available immediately to protect us from disease causing bugs. This includes non-specific immune cells which engulf viruses and bacteria as well as physical protections including our cough reflex and barriers, such as our skin, stomach acid and gut lining.
Adaptive Immunity
This is the way our body can develop defences which are specific to a particular bug. The first time we are exposed to a bug it can take our body a few days to create specially targeted white blood cells to combat the infection.
Acquired Immunity
Is the lessons our immune system learns throughout our life. Once we have been exposed to a bug, our immune system holds a memory which allows it to launch the specifically targeted immune cells much faster. This explains why we are less likely to become sick with the same infectious disease twice.
Passive Immunity
Refers to obtaining immune cells from others, such as how breastfeeding transfers immune cells from mum to baby.
Protecting the Vulnerable
When we have not been exposed to a bug before and allowed to develop acquired immunity. This means that even those with a well-functioning immune system may be susceptible to becoming unwell. Those who have weaker immune systems are more likely to develop severe illness and, as such, need to take extra precautions.
Taking Small Steps
Humans are remarkably adaptive and when we all start settling into new routines, we begin reflecting on what this challenge might teach us.
Remember, even small changes such as staying hydrated, getting some sun, fresh air, a gentle walk, and rest can be enough to make a difference to our health. For now, be kind to yourself and each other - the same sun shines on us all.
