What kind of patients need to suck human blood and are afraid of the sun

Is the difficulty of the legendary vampire disease?

With the sun, crops and trees on earth can sprout, grow leaves, blossom, and bear fruit; Birds, beasts, insects, and fish can survive and reproduce. If there were no sun, there would be no plants on the planet, and there would be no animals. The grains, vegetables, fruits, and meat we eat, and the cotton, linen, wool, and silk we wear are all closely related to the sun.

Coal buried in the ground may seem to have nothing to do with the sun, but it cannot be formed without the sun. Because coal was made from ancient botanicals under the strata.

When the water on the ground is exposed to the sun, it absorbs the heat and turns into water vapor. When the water vapor is cold, it condenses into countless small water droplets, which float in the air and turn into clouds. The smaller the water droplets in the clouds gather and become rain or snow falling.

When the sun hits the ground, some areas absorb more heat, and the air there is hotter; Some areas absorb less heat, and the air there is colder. The air can flow and become wind only when it is hot and cold.

Sunlight has the ability to kill germs, and we can use it to prevent and ** diseases.

The light and warmth on the earth are sent by the sun. If there is no sun, the earth will be full of darkness, everywhere cold, there will be no wind, snow, rain, dew, no grass, no wood, no birds, no beasts, and naturally there will be no people. In a word, without the sun, there would be no beautiful and lovely world of ours.

The light and warmth on the earth are sent by the sun. If there is no sun, the earth is full of darkness, everywhere cold, and there is no wind. Snow.

Rain. Dew, no grass. Wood.

Bird. Beast, naturally there will be no people. In a word, without the sun, there would be no beautiful world for us.

Let me tell you, the sun is 100 million kilometers away from us. If you walk, it will take about 3,500 years, and it will take more than 20 years to make an airplane.

The sun is actually very big, and only 1.3 million earths can be worth one sun.

The surface temperature of the sun is 6,000 degrees Celsius, and even if steel touches it, it will turn into gas, and the core temperature is estimated to be 2,500 times the surface temperature.

The question of handsomeness made me feel like a father for a while Do you know why, haha, what do you know about it?

The most direct relationship is that there is no sun, there is no one, but vice versa, thank you, please ask.

Because: people sleep later than the sun!

No matter what time you wake up, it's not as early as the sun, because when you get up and see the sun, you're already late.

Because the earth revolves around the sun every day.

Caused by the natural biological clock, if you wake up earlier than the sun every day, then your biological clock will be disordered, so why bother.

Because there are people who need days.

The question of weakness, I'm here to play soy sauce.

Baby Anne

Tie the girl's pigtails.

Healthy pig honey.

I'm in a good mood and love what's wrong.

Rough belching a py

Catfish. Is there one you like? I'm struggling with it.

A glimmer that slides off your fingertips.

A ray of sunshine in winter.

Crying or not returning those joys.

Outside the window, there is a trace of slanting sun.

I like all of this.

Don't be obsessed with sister

You say I've changed, but what about you?

Hello! I do that a lot.

The upstairs method is very good! Thumbs up for one, especially the second way to buckle the soles off.

I have a suggestion though:

If you want to walk barefoot, it is best to walk at home, because one is that the home is clean, and the other is that the ground at home is flat and will not hurt your feet! And you won't get sick from walking barefoot on the ground.

You can also go to the grass of a nearby park for even better results!

Good luck! o( o haha

Going swimming or practicing yoga are all barefoot methods.

Other lights are fine, but the sunlight is much better. It's not so easy to die, at least not by "days".

When it is completely dark for too long, I think there will be a big problem with the human eye, and the vision will deteriorate greatly; It can also malabsorb nutrients, such as vitamin D by ultraviolet light, which can only be absorbed directly or in other ways.

The visible light in the sunlight can be provided by the illuminator, and there is no shortage of light in the infrared band around us (hot-red), there is no sunlight, and the most important thing is that the lack of those wavelengths in the ultraviolet band has a great impact on us (sterilization, ** bottom synthesis of vitamin D......)

It shouldn't be soon, at least for years.

It won't die, but it will have loose bones. Without sunlight, vitamin D cannot be synthesized.

No, that's so scary.

At best, it will be moldy.

Hahaha. ~
