I think you should write about climate change instead, I think this is more interesting. Regarding about your question, I guess umbrella cannot give you a total protection against the heat and in my opinion I think the light colors is good since it tends to reflect heat than darker colors.

First of all. Umbrella dont protect us from uv ray. second, if we want protection againsts the sun uv ray, we can simply hide from it by not going outside or use sun screen it will protect a little. Third understand the color of the rainbow, there is a hint. the first the red color will harm us a little, the last color which is violet will really harm us. I think color white will protect us since it reflects back the uv ray outside the earth,problem is it turns back to us because of global warming. I think those were the simple tips. if there is any question , am gladly answer it back. Your thesis is interesting.

Most common umbrellas fail to give you protection against ultra violet radiation...then why the hurry over researching into the topic?

Just as we have a uv protection lense in our sun glasses could we have a similar material for our umbrella.But i suppose that would be very expensive.But even if there is an umbrella to protect us it'll only be partial as the sun's uv could come from all directions.I think the problem is not as easy as it first appears.

hi ...khulit i think your topic is not complex and will for it get more data around you ... to me i think most of the umbrellas we uses don't protect us from the sun's radiations...and also i agree with that all of us at must cases to use the ambrella for one propose that take carry us from the rain ...seldom uses for protect of the sun...and to say about the color that will be the black -the black may save our skin from the some harmful rays come from the sun .... have a nice day ...

Hello Khulit, we do know that umbrella do protect us from sun's heat but not totally, unless we used sunblock creams or lotions. And using white clothes will not absorb so much heat unlike with colored clothing especially black one. Actually in doing thesis you must always remember the word SMART... you need to base your thesis according to the acronym S - Specific, M - measurable, A-attainable, R- realistic, T-time bounded. or you add or make it smarter - E everything for R- Real Try to have more ideas, don't just stick to your subject now. Happy mylotting.
