My outdoor trip - skin burns

Yesterday, I went outside in a bike at about 1000 hrs to city outskirts to see someone. As it was very hot and also the distance is about 50 km and it took totally about 3 hrs to complete our trip, by the time we reached home, we were totally exhausted. I wore a half shirt and both fore arms as well as exposed portions of toes are burning / itching. At about 15 km from my house, we started taking different types of fluids, like pudina water, water melon, lemon soda, ice cream, coold drink, etc. However, by the time we reached, we were totally exhausted and there was no power at home due to scheduled power cut.
After lunch, I slept for about two hours and when I woke up and washed my face, I could see my red face, red forearms, red skin below the neck in the front side. This is like 1st degree burns. Even after 24 hours now also I am having skin burning sensation in the calf area and fore arm. Like any skin burn, it may take a week to return to normal skin.

Though, I wore a hat and covered my eyes with spectacles (photo sensitive), still I am suffereing from the travel under the hot sun. If this is the case with me who travel only very rarely, what about the workers who work for livelihood. What are the minimum measures to be provided to them to protect them hot sun and in this country, how many are really providing these facilities like sun shade, water, etc is a big question mark.
