Hanoi health risks: Hanoi is far enough north that for six months of the year (from October to March), it experiences a climate that has more in common with Europe than tropical Southeast Asia. However, temperatures rocket in summer, and when accompanied by high humidity, these conditions can make sightseeing in Hanoi a tiring activity.
Hanoi health risks: the most common problem for travellers in Vietnam is an upset stomach caused by changes in eating habits. With its bewildering range of unusual herbs, Vietnamese cuisine is bound to have a few surprises in store for your stomach.
Hanoi health risks: dehydration is the great danger, so make sure you carry plenty of water with you or stop frequently for a cool drink. Avoid walking around the city in the midday sun and take regular breaks in air conditioned shops or restaurants to recover a little.
Hanoi health risks: any tummy trouble will probably manifest itself in the form of an attack of diarrhoea. This can be rather distressing if you are on the road, but if it hits you while in Hanoi, just rest up for a few days, drink plenty of liquids and trust your insides to set themselves right.
Hanoi health risks: Medications such as Immodium are fine when undertaking a lengthy bus or train journey, but should be avoided otherwise as complications can arise from not allowing the infection to escape
Hanoi health risks: although there is no risk of Malaria in Hanoi, there are sporadic outbreaks of dengue fever. Previously known as ‘breakback fever’, this nasty mosquito-born bug causes a rash and intense pain in the joints, and can be fatal without medical care.
Hanoi health risks: drink bottled water rather than tap water, and be cautious about consuming ice. There’s no need to worry about iced drinks in top hotels, but on the street it’s a different matter; to be on the safe side, choose a drink that has already been chilled in a fridge.
Hanoi health risks: Another potential danger of street eating are the bowls of fresh salad and herbs that are placed on tables for diners to help themselves. These should of course be thoroughly washed before being eaten, so if you are unsure about their preparation, it’s safer to pass on these extras.
