Its rain! How it works? from where it get the energy? Rain!Doesn't rationalize people to spread the blessings, it just do its work. The blessings makes the fields incredible, the scenerio awesome, seed futile, the living being happy etc...many more countless things. We humans doesnt pay this back, but the rain loves still..despite of being one side and alone, it is love which gives it energy...!

What Is Rain?

Love & Family

Preetesh Paliwal on Sep 12

After asking my friends and hearing people say how much they love the rain i wonder what made rain loved by many when it was depicted as a lonely and sad time of the day.Rain's CompanyMaybe it's because of that! People often find happiness and tranquility when they are alone, the rain may just add to the flavor of solitude.People's suppressed emotions will be able to flow out, competing with the sound of rain hit the rooftops.It is also for me, i enjoy being alone accompanied by books, blankets, paper and, a pen. Though i enjoy the silence i dont mind listening to the rants of the sky.

Love For Rain

We are surrounded by sound waves. Sound has the power to communicate ideas, scare us, entertain us, even help us fall in love. Sound waves are a kind of energy that is launched when an object vibrates. These waves travel through a medium like air or water. When they reach your eardrum, the brain translates the pressure waves into words or music.

Sound waves are a type of power

The shape of waves is rolling peaks and valleys. If the wave moves faster, the peaks and valleys form closer together. If it moves slower, the waves spread out. <ul><li>The speed of a sound wave - how fast the waves move from peak to trough - is called frequency, but we also know it as pitch. We measure sound frequency in hertz (Hz), which is the cycles per second.</li><li>Understanding frequencies is useful. For example, you can tune an instrument - middle C on the piano is tuned to the frequency of 261.63 Hz.</li></ul>

Sound frequency

<ul><li>Amplitude (amps) describes the height of the sound waves and gets measured in decibels (dB).</li><li>Timbre is the perceived sound quality. You can distinguish the unique harmonics of timbre by the combination of notes in a chord.</li><li>Envelopes determine how a sound's amplitude changes over time. It can be quick and loud, like a door slamming, or it can slowly increase in volume, like a cello's note.</li></ul>

Other useful sound terms

Sound must travel through a medium like water, air or even sand. It means you will never hear an explosion in a vacuum. The speed of sound, or the sound's velocity, differs depending on how dense the medium is it's moving through. Generally, the speed of sound is 1,127 feet per second or 767.54 miles per hour.

The speed of sound

Musicians and content creators need knowledge of frequencies and amplitude in their home recording set-ups to ensure their voice sounds rich and clear. Understanding sound can help them choose microphones best suited and help to set up the room to reflect or dampen sounds.

Most people seem to be sleepy when the weather is dark and rainy. For the longest time I've had my own theory about it but I also decided to do some research. Here is the best explanation I could find for why rain and sleep go together.Bonus - see the last idea for my own, unproven theory.

The connection between rain and sleep

The absence sunlight triggers our bodies to stop producing the hormone melatonin, which makes us sleepy at night. When it’s raining and skies are overcast, we miss out on our body’s internal alarm clock.&nbsp;Naomi Rogers, a chronobiologist from Central Queensland University, told the Sydney Morning Herald, that when you don’t see the sunlight first thing in the morning, your body never gets the cue that it needs to shift into daytime mode.

Less sun, more melatonin

Earthy smell of rain can be soothing. Plants secrete oils during dry periods, possibly to stop seeds from developing when there aren’t enough resources for them to thrive. When it rains, the water brings out the accumulated oils and they mix with a chemical called geosemin, which is produced by soil bacteria, to create a “musky” smell.Bill Ypsilantis, a soil condition and health specialist at the Bureau of Land Management, told NPR that this is the same smell you feel when turning over the soil.

The smell of rain

Also there is the smell of ozone - a molecule made of three oxygen atoms, generated when lightning interacts with the air, breaking up and recombining oxygen molecules with two atoms into chains of three instead.It also creates a powerful association with rain.

Rain sounds are also comforting. The rhythmic pitter-pattern of rain hitting a roof, umbrella, or the ground below is called pink noise. Pink noise is a category of background noise that, like white noise, has all of the frequencies that humans can hear, ranging from 20 Hz to 20,000 Hz. Unlike white noise, which has the same volume at every frequency, pink noise has lower volumes at higher frequencies, which according to some research may improve our quality of sleep by decreasing our brain activity.

The sound of rain

So the combination of melatonin, smell and sound creates the conditions for being sleepy.My own theory has to do with preservation of energy. If it rains most animals have a harder time to foridge for food or you can even get sick if you prance around in the rain.&nbsp;If you can't eat you better not spend energy. And what better way to do it except by spending a rainy day in a borrow or our own beds? I think we just evolved to be lazy during rainy days. I still like my theory, although there is no proof for it.

The theory of laziness

Sleep

Why does rain seem to make you sleepy?

It takes many forms, from the tiny particles that are emitted when we cook or clean, to the spores released by mold when it’s damp, and the chemicals that are embedded in our furniture.Small particles that are inhaled can travel to the lungs and cause problems. Studies suggest that indoor air pollution is linked with an increased risk of certain respiratory problems, such as asthma and bronchitis.

Indoor air pollution is widespread

<ul><li>Cooking releases particulates into the air, and that levels can remain elevated long after cooking is finished.&nbsp;</li><li>Open a window when you cook and use the extractor fan if you have one.&nbsp;</li><li>Put the pot on the back burner, where it will ventilate to the fan more efficiently.&nbsp;</li><li>Keep the fan on for at least 10 minutes after cooking ends.</li><li>Cook with electricity, if you can. It’s more environmentally friendly and less polluting than gas, because gas appliances generate carbon monoxide and nitrogen dioxide.</li></ul>

Use the back burner

Open fires and older wood-burning stoves emit a mixture of gases and tiny particles. Burning wet wood is worse than dry, seasoned wood.&nbsp;The Department for Environment, Food and Rural Affairs (Defra) recommends burning wood that has a moisture content of less than 20 per cent, along with certain stoves that are less polluting.

Use your log burner sparingly

Candles and incense can also impact air quality.&nbsp;One study in Danish homes found that candles were the main source of indoor pollution.

Don’t go overboard with candles

Cleaning products and indoor fragrances produce various volatile organic compounds which can be suspended in the air or settle in dust and on surfaces.&nbsp;Spray cleaning products close to the surface, then wipe with a dry cloth, then wipe again with a cloth that’s been dampened in water.

Clean with care

Fabrics and certain furnishings are treated with flame retardants, and formaldehyde can be found in some furniture, floorings, and building materials.&nbsp;Although we can’t yet confidently identify the extent of any health effects that are caused, we need to establish set emission standards and a clear labeling system for these items.

Furniture as a source of indoor pollution

Outdoor studies hint that plants can help provide a barrier against some forms of pollution, but the evidence from indoor studies is still lacking.&nbsp;It is not yet knows if specific plants can reduce air pollutants in the home, but they certainly look good and are great for our wellbeing.

Indoor plants

Help to prevent damp by cleaning away condensation and mold, and ventilating rooms as thoroughly as possible.&nbsp;If your windows have trickle vents, keep them open.

Be aware of damp
