The sun is another foe that can cripple an expedition, especially in the South American jungle. As much as you might want to soak in some rays, the sun can put you in agony in the short term (and far worse in the long term) if you don’t take appropriate precautions. You’ll notice that everyone in the crew was covered almost head to toe, including our Indian guides Juanito and Ramon, seated fore and aft in the canoe in the foreground. The lesson with the sun is all about prevention. if you feel the symptoms of sun sickness in the jungle, you’re already behind the eight ball.
