          irt and germs are probably at the top of the
        
        
          list of things parents want kept away from
        
        
          their children. But children love to explore,
        
        
          so it’s not always easy to keep kids and germs
        
        
          apart. Hulda Thorey, founder of Annerley and a mother
        
        
          of four, recalls the time her eldest son got into the sandbox
        
        
          and ate the sand, plus part of his knitted hat. “Both the
        
        
          sand and threads came right through him undigested.
        
        
          Very attractive in the diaper!” she remembers. For Hulda
        
        
          and most parents, it’s not easy to stop young children
        
        
          from putting everything around them into their mouths.
        
        
          But while all parents want to protect their children from
        
        
          exposure to infectious diseases, is this fear of germs limiting
        
        
          our children’s freedom to explore outdoors, which is so
        
        
          important to their overall development?
        
        
          Hygiene hypothesis
        
        
          In 1989, a researcher named D P Strachan published
        
        
          the “hygiene hypothesis” in the
        
        
          
            British Medical Journal
          
        
        
          .
        
        
          The theory is that diseases such as asthma and allergies
        
        
          are becoming more common because children are not
        
        
          exposed as often to the bacteria that help build their
        
        
          immune systems.
        
        
          Ronald M Ferdman, MD, at the Keck School of
        
        
          Medicine, who primarily treats children with severe
        
        
          allergic and immunological conditions, notes that, “It
        
        
          seems that parents these days are a lot more worried about
        
        
          minor infections in their kids ... Nobody would say that you
        
        
          should purposely expose your child to infections. On the
        
        
          other hand, there is no need to keep children in a bubble.
        
        
          In America, there is no risk of exposing children to malaria
        
        
          or some horrendous disease. But parents do get upset if
        
        
          their child comes down with a cold.”
        
        
          There’s no need to be over-vigilant when it comes to
        
        
          being sanitary, since not all germs are bad. Hulda says,
        
        
          “
        
        
          Playing with sand, in the grass, in water, on the floor –
        
        
          Put down the alcohol wipes! A few germs might
        
        
          not be such a bad thing, writes
        
        
          
            Katie McGregor
          
        
        
          .
        
        
          there are healthy bacteria that children become exposed
        
        
          to when picking up, touching and probably licking things
        
        
          from the floor and the environment. Children are able to
        
        
          develop their own immune system, rather than relying
        
        
          solely on immunisation.”
        
        
          Hulda, who lives on a boat, prefers to have her children
        
        
          exposed to the sea, sand and rain. “Any time it rains, I put
        
        
          mine outside, instead of inside,” Hulda says. “Don’t get me
        
        
          wrong: I am not trying to suggest that children should be
        
        
          in unsafe environments – quite the opposite: kids should
        
        
          be able to play with supervision but without constant
        
        
          intervention by adults.”
        
        
          “
        
        
          Before allowing them to play somewhere, make sure
        
        
          that the place is safe,” Hulda says. “The objective is to
        
        
          put babies in a normal environment without hazards.”
        
        
          The benefit of allowing children to play freely is that they
        
        
          become familiar with sensing objects that exist in nature,
        
        
          rather than just ready-made and sterile toys.
        
        
          The balance is crucial for a child’s development: when
        
        
          parents over-sanitise their children’s environment to protect
        
        
          them from exposure to diseases, they are depriving their
        
        
          children of the opportunity to build up their immune systems.
        
        
          The upside to outside
        
        
          In addition to building a stronger immune system, letting
        
        
          children play outdoors can have many other benefits.
        
        
          Playing outside can lower a child’s chances of obesity.
        
        
          Outside play is associated with higher physical activity than
        
        
          playing indoors, and the US-based Centers for Disease
        
        
          Control and Prevention recommends one hour per day
        
        
          of outdoor play. Activities such as running, jumping and
        
        
          climbing are enough to engage a child’s cardiovascular
        
        
          system and major muscle groups to help them grow up
        
        
          healthy and strong.
        
        
          Another benefit of outdoor play is that it can help with
        
        
          the production of vitamin D, which is primarily produced
