Flu, acute pharyngitis and heat stroke

Dehydration is the most reason for health issues in tropical climate.

Dehydration is very common and should be taken seriously when doing outdoor activities. 
A deficiency in water weakens the immune system, making human body vulnerable to infection. In addition to this, there is a common habit called "smash the thirst" by drinking cold water and using air conditioners for long periods. 

However, people often ignore that these behaviors cause a sudden change in body temperature. Drastic shifts in temperature actually enfeeble the immune system and cause health issues like flu, acute pharyngitis and heat stroke. 

Drinking two to three liters of water per day will help keep your body fit. To boost your immune system and prevent virus penetration you should choose foods high in zinc and vitamin C. 

Remember, keep your air condition set between 26 and 28 degrees, the optimal temperature for the human body. It's also important not to take a cold shower if you are sweating or to bathe right after coming back from outdoors. 

Skin infection

Drinking water protects you from dehydration in hot weather.

In hot weather, excessive sweat combined with dirt can clog the pores causing bacteria to “lodge” in the skin. Once bacteria have imbedded itself in the skin, it can lead to several diseases such as folliculitis, acne, rash, dermatophytosis…

Moreover, with climate change, ultraviolet radiation can exceed the safety threshold, which makes sunbathing or long-distance motor biking harmful for skin. 

Without proper sun protection, your skin will suffer from burns, hyperpigmentation, and even skin cancer. Exposure to ultraviolet radiation can also cause damage to your eyes causing many irritating problems such as retinopathy and dazzle reflex… 

To avoid these problems, always keep in mind to wear eyeglasses, use sunscreen lotion, wear sweatshirts, and try not to expose yourself to sunlight for 10-16 hour periods.

Dengue fever

Always apply sunscreen lotion in outdoor activities.

In Vietnam, when the summer humidity combines with the sudden downpour of rain, it’s an ideal condition for mosquitoes to populate. These conditions coincide with the high risk of dengue fever.

Therefore, you should be well prepared when going on a picnic, camping or even sleeping at home. Mosquito repellant should be your inseparable item. Put on long clothing and avoid wearing dark colors when going out to help prevent insect attraction. 

If you have never slept under a mosquito net, start getting used to it, as it is one of the most efficient ways to prevent mosquito bites.

Intestinal diseases

Prepare mosquito repellant when going outside to prevent insect attraction.

Finally, the hot moist air promotes the growth of bacteria. These bacteria easily attach to food, which is the primary cause of food poisoning and intestinal infection. 

Bacteria have long life cycles and spread to other foods, particularly from raw to cooked food. You should be cautious when buying or eating food outside. 

At home, remember to preserve food properly to ensure hygiene and add pro-biotic foods into your diet, such as yogurt, to improve the health and quality of your intestinal tract and gut. Of course, always remember an Vietnamese idiom “eat cooked food and drink boiled water” (Ăn chin uống sôi) - as a key to safety!
