Most children love to get dirty, and now it has been proven to have a positive impact on their health and mental well-being! According to recent research, the dirt outside is thriving with friendly microorganisms that can train the immune system and build resilience to a range of illnesses including allergies, asthma and even depression and anxiety. However with video games and social media being so popular, children’s encounters with nature are much less frequent.

Natural landscapes are thought to recharge the brain when it is tired and easily distractible. In 2009 a study found that children with attention-deficit hyperactivity disorder (ADHA) were able to concentrate more after a 20-minute walk in the park, compared to a 20-minute walk on a built up street. The authors recommended using such “doses of nature” as a safe and accessible way of supporting children with AHD, alongside other tools. For example, “Sand Tray Therapy” which involves using sand and mini figurines to express thoughts and feelings, is an accepted form of counselling for children who are struggling to verbalise their emotional state.

Lets talk about those friendly microorganisms: Mostly harmless and been around forever, they help train the immune system to moderate its activity, rather than overreact to any potential invader. Importantly our bodies meet these little bugs when we spend time in nature. With reduced outdoor play, many children now lack the exposure which means their immune systems are more sensitive to any threat.

Surprisingly, these friendly bugs can even moderate the body’s response to stress. The natural reaction for a human body when feeling vulnerable and threatened is inflammation, to prepare for any potential physical injury – however this is useless for the kinds of stress that most people face today. By being introduced to these microorganisms, our immune systems are better prepared to deal with any threat and dont go into panic mode.

Given the known psychological benefits, more school sand nurseries are encouraging greater contact with nature ,with outdoor lessons, and nature walks. Mud kitchens in particular can be a cost effective way to reintroduce activities that children may not get a chance to partake in at home. All you need is some pots and pans filled with a mixture of soil and water! As the children let their imaginations run wild, developing many various skills, their immune system is being optimised and the potential benefits could last for years!
