[ 💕 ] Sunbathing is a popular leisure activity in which a person sits or lies in direct sunshine. People often sunbathe in comfortable places where there is ample sunlight. Some common places for sunbathing include beaches open air swimming pools parks gardens and sidewalk cafes. Sunbathers typically wear limited amounts of clothing or some simply go nude. For some an alternative to sunbathing is the use of a sunbed that generates ultraviolet light and can be used indoors regardless of weather conditions. Tanning beds have been banned in a number of states in the world. ㅤㅤㅤㅤㅤㅤㅤㅤ.. 🔴 : 🚬 : 🤡 .. ㅤㅤㅤFor many people with light skin one ㅤㅤㅤPurpose for sunbathing is to darken ㅤㅤㅤOne's skin color (get a sun tan) as this ㅤㅤㅤIs considered in some cultures to be attractive associated with outdoor activity vacations/holidays and health. Some people prefer naked sunbathing so that an "all-over" or eventan can be obtained sometimes as part of a specific lifestyle. Controlled heliotherapy or sunbathing, has been used as a treatment for psoriasis and other maladies. ( .. ) 🚩

in many world religions such as Hinduism the sun is considered to be a god as it is the source of life and energy on Earth. The Sun was also considered to be a god in Ancient Egypt. music.com < 🎳

ㅤ ㅤㅤ𖧋 𖧋 😂 Heterotrophs such as animals use light from the Sun indirectly by consuming the products of autotrophs either by consuming autotrophs by consuming their products or by consuming other heterotrophs. The sugars and other molecular components produced by the autotrophs are then broken down releasing stored solar energy and giving the heterotroph the energy required for survival. This process is known as cellular respiration. During the Neolithic Revolution the domestication of plants and animals further increased human access to solar energy. Fields devoted to crops were enriched by inedible plant matter providing sugars and nutrients for future harvests. Animals that had previously provided humans with only meat and tools once they were killed were now used for labour throughout their lives fueled by grasses inedible to humans. [ Fossil fuels are the remnants of ancient plant and animal matter formed using energy from sunlight and then trapped within Earth for millions of years. ] 🎳🎳

,, 🔱 > rant.com In prehistory humans began to further extend this process by putting plant and animal materials to other uses. They used animal skins for warmth for example or wooden weapons to hunt. These skills allowed humans to harvest more of the sunlight than was possible through glycolysis alone and human population began to grow.

🚬 .. The existence of nearly all life on Earth is fueled by light from the Sun. Most autotrophs such as plants use the energy of sunlight combined with carbon dioxide and water to produce simple sugars—a process known as photosynthesis. These sugars are then used as building-blocks and in other synthetic pathways that allow the organism to grow. ❤️‍🔥 | ❤️‍🔥 ㅤ

The Sunㅤmay be ㅤ👹 said to ㅤilluminate, which ㅤis a ㅤmeasure of ㅤthe lightㅤ 🪬 within aㅤ specific sensitivity range. ✪ < Many animals (including humans) have a sensitivity range of approximately and given optimal conditions the absorption and scattering by Earth's atmosphere produces illumination that approximates an equal-energy illuminant for most of this range. The useful range for color vision in humans for example is approximately. Aside from effects that arise at sunset and sunrise the spectral composition changes primarily in respect to how directly sunlight is able to illuminate. When illumination is indirect Rayleigh scattering in the upper atmosphere will lead blue wavelengths to dominate. Water vapour in the lower atmosphere produces further scattering and ozone dust and water particles will also absorb particular wavelengths. 💢 🏎️ 🍟ㅤㅤㅤ

🦇 : The spectrum of surface illumination depends upon solar elevation due to atmospheric effects with the blue spectral component dominating during twilight before and after sunrise and sunset respectively and red dominating during sunrise and sunset. These effects are apparent in natural light photography where the principal source of illumination is sunlight as mediated by the atmosphere. 🤟 : While the color of the sky is usually determined by Rayleigh scattering an exception occurs at sunset and twilight. "Preferential absorption of sunlight by ozone over long horizon paths gives the zenith sky its blueness when the sun is near the horizon". See diffuse sky radiation for more details.

⸻ { 🎱 ★︭ Dividing the irradiance of by the size of the Sun's disk in steradians gives an average radiance of square metre per steradian. However the radiance at the center of the sun's disk is somewhat higher than the average over the whole disk due to limb darkening. Multiplying this by gives an upper limit to the irradiance which can be focused on a surface using mirrors. The illumination of a horizontal surface will be considerably less than this if the Sun is not very high in the sky. Averaged over a day the highest amount of sunlight on a horizontal surface occurs in January at the South Pole (see insolation). {} 🪷 The actual brightness of sunlight that would be observed at the surface also depends on the presence and composition of an atmosphere. For example venus's thick atmosphere reflects more than of the solar light it receives. The actual illumination of the surface is about comparable to that on Earth "in the daytime with overcast clouds". ㅤㅤㅤㅤㅤㅤㅤㅤㅤ🔪 ㅤ|ㅤ 🔪ㅤ |ㅤ🔪 🔪,, Sunlight on Mars would be more or less like daylight on Earth during a slightly overcast day and as can be seen in the pictures taken by the rovers there is enough diffuse sky radiation that shadows would not seem particularly dark. Thus it would give perceptions and "feel" very much like Earth daylight. The spectrum on the surface is slightly redder than that on Earth due to scattering by reddish dust in the Martian atmosphere.

ㅤㅤㅤ𖤍 .. Researchers can measure the intensity ㅤOf sunlight using a sunshine recorder ㅤㅤㅤ 🚨 'Pyranometer or pyrheliometer to calculate ㅤㅤㅤㅤㅤㅤㅤㅤ . 💀 the amount of sunlight reaching the ground both the eccentricity of Earth's elliptic orbit and the attenuation by Earth's atmosphere have to be taken into account. The extraterrestrial solar illuminance eext corrected for the elliptic orbit by using the day number of the year is given to a good approximation by. Direct sunlight has a luminous efficacy of about lumens per watt of radiant flux. This is higher than the efficacy (of source) of artificial lighting other than which means using sunlight for illumination heats up a room less than fluorescent or incandescent lighting. Multiplying the figure of watts per square meter by lumens per watt indicates that bright sunlight provides an illuminance of approximately lumens per squareon a perpendicular surface at sea level. ❓
