The weather in the sun is blazing sometimes annoying, especially when we are indoors in the open. When this happens, often the shade of the shade tree becomes the angel of the savior.
Tree shade is really cool, protect our bodies from the sun's heat.
Have you ever wondered why the shade of the trees is cool?
At first glance, this answer seems reasonable. However, this answer is incorrect, as not everything that blocks the sun can cool you down. The proof, you try to take shelter under the zinc, then the coolness will not get you. It's just hot and sultry you'll find. Why?
The zinc roof is unable to provide a cool shade because zinc is included metal, while the metal is a good heat conductor. Well, when the heat of the sun on the zinc, the heat will spread easily. As a result, a lot of heat passes up to the bottom of the zinc. You who stand under the zinc was finally felt the heat.
So, why does the shade feel so cool?
Plants always need sunlight for photosynthesis. Part of the plant in charge of collecting sunlight is the leaves. So instead of continuing the heat, the leaves actually absorb the heat to convert it into photosynthetic energy. As a result, there is no hot spreading to the bottom of the leaf, and this presents a cool atmosphere for those who take shelter under it.
These principles can be used to explain why the tile roof feels more soothing than the tin roof, and why we need to install a triplex ceiling under a zinc roof. Everything is based on the nature of the conductivity of the body to heat.
In addition to absorbing the sun's heat, there is one more thing that makes shelter under the tree feels so comfortable. The by-product of photosynthesis is oxygen. Oxygen is expelled through the stomata, which are widely present on the lower surface of the leaf. The presence of oxygen supply makes your breathing feel fresher when shelter under the tree.
