Common health problems
The main health problems experienced by visitors – including many blamed on the food – have to do with overexposure to the sun. To avoid these, cover up, wear a hat, and drink plenty of fluids to avoid any danger of sunstroke; remember that even hazy sun can burn. Tap water meets strict EU standards for safety, but high mineral content and less than perfect desalination on many islands can leave a brackish taste not suited to everyone. For that reason many people prefer to stick to bottled water . Hayfever sufferers should be prepared for a pollen season earlier than in northern Europe, peaking in April and May.
Hazards of the sea
To avoid hazards in or by the sea, goggles or a dive mask for swimming and footwear for walking over wet or rough rocks are useful. You may have the bad luck to meet an armada of jellyfish (tsoúkhtres), especially in late summer; they come in various colours and sizes ranging from purple “pizzas” to invisible, minute creatures. Various over-the-counter remedies are sold in resort pharmacies to combat the sting, and baking soda or diluted ammonia also help to lessen the effects. Less vicious but far more common are spiny sea urchins, which infest rocky shorelines year-round. If you step on or graze against one, an effective way to remove the spines is with a needle (you can crudely sterilize it with heat from a cigarette lighter) and olive oil. If you don’t remove the spines, they’ll fester.
Bites and stings
Most of Greece’s insects and reptiles are pretty benign, but there are a few that can give a painful bite. Much the most common are mosquitoes: you can buy repellent devices and sprays at any minimarket. On beaches, sandflies can also give a nasty (and potentially infection-carrying) sting. Adders (ohiés) and scorpions (scorpií) are found throughout Greece. Both are shy, but take care when climbing over drystone walls where snakes like to sun themselves, and – particularly when camping – don’t put hands or feet in places, like shoes, where you haven’t looked first.
Finally, in addition to munching its way through a fair amount of Greece’s surviving pine forests, the pine processionary caterpillar – which takes its name from the long, nose-to-tail convoys – sports highly irritating hairs, with venom worse than a scorpion’s. If you touch one, or even a tree trunk they’ve been on recently, you’ll know all about it for a week, and the welts may require antihistamine to heal.
If you snap a wild-fig shoot while walking, avoid contact with the highly irritant sap. The immediate antidote to the active alkaloid is a mild acid – lemon juice or vinegar; left unneutralized, fig “milk” raises welts which take a month to heal.
