The Summer season is started and my body heat is increased too. Is there any way to reduce my body heat and keep it in control.
I recently moved from a country with moderate to cold climate to one that is hot all year around and I noticed that I simply wasn't consistent enough to always wear flip flops/sandals and shorts. I know is sounds so obvious, but just these two make a big difference. I also see a lot of people wearing long jeans here. And in reverse I would say: never wear long jeans. Super loose Pakistani style pants look alright to. Maybe you like that or something similar.
Try to wear fresh clothing, do not ingest caffeine that will make you really active, organize your daily routes so you move or walk less, keep areas well ventilated, avoid food with high calories content, drink fresh water, coconut water is really good and refreshing, its electrolites help you rehidrate, also lemon, avoid spicy food, soak your feet in cold water.
Including some of the mentioned things in your daily routine will help you to keep your body cool or at least less hot.
