If you get bitten too much it can trigger an allergic reaction through your entire body. That can happen to anyone who gets bitten and has a tiny bump raise where they were bitten. The down side to wearing that mesh is that it won't help you against tiny biting midges or thrips. Those are too small and go right through everything that isn't good cloth.
Keep in mind that any place that touches the mesh will be a point of contact where the insects can bite you through the mesh.
