How to Minimize Sweating in Unusually Hot and Humid Weather?

Accepted answer

Your body is not used to the level of heat & humidity and is simply reacting as it should. On the other hand the locals' bodies are adapted to the heat and would likely freeze in a colder country.

Sadly there is no magic bullet, your body simply needs to acclimate which takes years, not days or weeks. Your body needs to shed internal layers of insulating fat, adapt the skin to higher humidity, allow capillaries to radiate more heat.

The biggest worry is overheating, if your body can not cool the core temperature down quick enough. If you are constantly sweating, especially after going indoors, then your cooling system is not winning the battle. And you need to slow down, relax more indoors.

For sun protection, forget sunscreen and get loose fitting long sleeved cotton shorts, pants and a hat. Sunscreen, especially the "waterproof/sweatproof" types actually hinders your body's sweating process leading to more overheating.

As you are already doing, drinks lots of fluids, but include some electrolyte drinks as well as water to replace some of the chemicals you are losing through sweat.

Add a little salt to your diet, perhaps simply shaking a bit more on your lunch or dinner foods to help replace your body's losses.

  • Leave the city area. Big cities with millions of residents are literally heat islands, even when they cool down at night the heat can be absolutely stifling. Remember that air conditioning only moves heat out, meaning that all those air conditioning outside the hotels heats the environment. Try to move to forested or coastal areas.

  • Drink much, but only small portions very frequently. The more you are drinking at once, the more will your body sweat, so while you need much water, drink only mouthfuls frequently.

  • There is no real way apart from air conditioning to protect against heat. This is one thing where being cold is better, you can always put some warm clothes on. The only thing to avoid heat is having no heat: using the night, going underground or staying only in air-conditioned rooms...but it really spoils your holiday.

  • Very cold showers/baths. If you are used to it, it helps to strengthen your cardiovascular system and has a very refreshing effect.

  • Japanese/Chinese mint oil. Be very careful with it, it is hurting like hell on mucous membranes and if you get it in the eyes, it is worse than pepper spray. It contains menthol which gives a cold stimulus without lowering the body temperature, one drop is very refreshing. One trick is to use 5 drops in a full cold bath.

  • Body constituition: I can relate to it, I seriously hate humid hot regions, but can tolerate temperatures which many people find cold and icy. One thing is that being obese or overweight is a severe disadvantage, because it combines high mass with comparatively smaller surface area and higher insulation.
