Different textures and colors also result in different reflections and dispersions of light. For example, using a light color or a smooth shiny surface will reflect and diffuse light better than a dark or matte and rough surface. Therefore, if you choose to use the best one tone, even the furniture will help spread the light, making the room brighter. The wall part of the room usually has the most space. So the choice of color is very important. If you want the room to be naturally bright, you should choose to use wall paint in light tones. In addition, the ceiling and floor should also be light in color and in the same tone. Adjusting the overall color of the room does not have to be painted but can be used with tiles, wallpaper… Use the help of the mirror Mirrors are important items that help to make a room brighter and more airy. If a mirror with a cute shape that matches the style of the room is placed in the opposite direction of the light hitting the door or window, it will help diffuse the light and make the room look bright. than. In addition to mirrors, there are many other types of furniture to choose from to brighten up the room. Of course, it should be soft furniture or have a shiny surface such as metal, acrylic or light wood to create a cozy space. Arrange the furniture The arrangement of furniture in the room is also another simple matter that affects the lighting. Especially large pieces of furniture such as sofas, wardrobes or bookshelves, televisions… which, if placed in the middle of the room, will form an angle that makes light unable to reach, even blocking the light. The layout Large pieces of furniture close to the walls in the room are the best way for light to shine through. But it should be an angle that doesn’t block the window or channel through which the light passes. In addition to allowing adequate natural light to pass through, it also helps to make the room look open and spacious. Use curtains to filter light Opening the window during the day in the corners that get direct sunlight will make the room too hot, in this case, many people have chosen to keep the curtains closed to solve it. However, forget that installing light-filtering curtains or adding a layer of light-colored curtains can help. During the night, the curtain can be used normally. During the day, the light-filtering curtain looks like a light-colored fabric pulled through, as it’s specially designed for daytime, it adjusts the light coming in for eye comfort as well. Selection of LED bulbs Nowadays, energy-saving and full-light LED bulbs are quite popular. This is also a way to help the room always be brighter and more airy without the need to install the same transparent balls everywhere. Just in the corner for main activities such as sitting, applying makeup or working, you must choose a lamp that provides enough light. In other corners, lower wattage bulbs can be used to give the room enough light without consuming too much energy. Manage trees and obstacles When arranging, tidying up, don’t forget the potted plants both inside and outside the room. Because plants are a thing that, if not properly arranged, can block light and make a room look cluttered. Hanging or facade plants should be small plants that are easy to manage and care for, while larger plants can be tilted away from the window sill rather than directly covering them. In addition, there may be trees and obstacles outside that block all the light from the window, so please regularly take care and prune.

1. Close the window blinds The first rule in keeping the house or apartment cool is to draw the window blinds, especially the west and northwest windows because 30% of unwanted heat comes from these locations. At the same time, when choosing curtains, you should choose those with neutral colors to avoid heat radiation. 2. Air conditioner increases by 1 degree Celsius, reduces power consumption by 10% If you live in an apartment or apartment that requires the use of air conditioning, keep the temperature at around 24-27 degrees Celsius or higher if you still feel comfortable. Remember, just 1 degree Celsius increase can reduce about 10% of the electricity of the air conditioner. 3. Adjusting the ceiling fan In the summer, you sometimes feel like a ceiling fan is only pushing hot air around the house rather than cooling it and this is exactly how it feels. Therefore, install the ceiling fan so that it rotates counterclockwise to push the air straight down, creating a cooling effect on the body, and remember to set it to run clockwise in winter to pull air. cool air. 4. Close the door and seal the openings Close the doors to rooms you don’t use to keep cool air where you need it most. Seal openings around doors and windows, and use draft-stops to ensure cool air can’t escape. 5. Open windows at night when it’s cool Closing your windows and staying indoors can be a great idea during the day, but as it gets cooler in the evening, you may want to open the door to naturally cool your home – but remember to lock the door when you leave. sleep. 6. Cool down the body Cooling your house or apartment doesn’t mean you don’t need to cool your body by using body-cooling drinks, putting a cool towel on your neck or some other acupuncture points to avoid heat shock. 7. Create air conditioner from fan No air conditioning? Do not worry! A cleverly placed bowl of ice is all you need to turn a fan into a cold mist. Place a basin of water or ice tray in front of the fan for a cool breeze. 8. Choose cool clothes Wear loose, light clothing made of breathable fabrics like cotton and change your bed sheets to cotton for more comfort. 9. Turn on ventilation fans in the kitchen and bathroom This is essential because it helps to get rid of hot air from cooking or after you shower all over the house. 10. Change the light bulb If you’re having trouble cooling your home and can’t figure out why, incandescent bulbs could be the cause. These bulbs were phased out in Australia many years ago, but in Vietnam many families are still using them. This type of bulb generates a lot of heat, so switching to energy-efficient bulbs can help cool your home and save you tons of energy costs. 11. Put a basin of water in the room Another trick to lower the room temperature is to put a basin of water in the room because on the high temperature the water evaporates will help reduce the temperature significantly to make the room cooler. 12. Put a lot of plants in the house Not only preventing dust and filtering the air, plants also have a great effect in lowering the temperature of the room. However, do not leave many trees in the bedroom at night because then it produces CO2, which is not good for health. Long-term measure 13. Limit the use of many electrical appliances Not only is it a matter of saving electricity, but also because the heat emitted from electrical appliances and household appliances during operation will add a few degrees of Celsius to your already secretive house. Therefore, families should focus on living in a room with scientific time instead of spreading it as usual. 14. Reduce the heat for the roof For private houses, especially on the street, because there is usually only one facade, blocked on all three sides, the heat of the sun entering the house is mainly from the roof. Therefore, you should add false ceilings with heat-resistant materials such as gypsum plaster, foam insulation bags to keep the house cooler. 15. Natural heat blocking If you live in a private house and have a land fund, use the shade of trees to cover the windows and walls. Plant deciduous trees that shade your home in the summer, but let the sun shine through in the winter. If you can, invest in tinting your windows to keep out more heat radiation.

The brain produces enough electricity to light a small light bulb Our brain has about 100 billion cells called neurons. When we move, look, think, dream or laugh, electrical and chemical signals are racing between the billions of neurons on this neural highway. So even though one neuron generates a very small amount of electricity, all of them together can generate enough electricity to light a low-wattage light bulb. Illustration. The sense of smell can take you back in time When we smell something that has a connection with something significant in our past, the first thing we experience is the emotion we had at that moment, then memory often follows. Sometimes we won’t remember the event or situation, but the emotion will be there. This ability actually has a very simple evolutionary explanation. There’s a part of our brain that’s dedicated to detecting chemicals that will signal us if something is approaching, that’s what our sense of smell does. This was very important to our existence in the past. Illustration. We can lift a 60kg person but cannot lift a 60kg rock When we lift “live weight” it is easier because the person can adapt to gravity and distribute their weight in more directions. If this person chooses, they can also put their arms around you, which will make things easy. While lifting an object, such as a rock, the rock cannot choose the distribution of its gravity and weight. Gravity is in the default position and this makes lifting it a lot harder. Illustration. Women’s brains shrink during pregnancy A study confirms that “pregnancy brain” is more than just a phrase used to explain the emotional roller coaster a mother-to-be goes through. The brain actually shrinks during pregnancy, but this is not a negative thing. As it gets smaller, it becomes more effective and the woman prepares for becoming a mother. In fact, the loss of gray matter occurred in the part where it would enhance her understanding of other people’s beliefs, emotions, and nonverbal cues. These changes will boost her ability to bond with her infant and make her aware of threats so she can protect her baby and herself more quickly. To have super strength, the digestive system has to shut down Fatigue, pain, and fear are all things that prevent us from trying to use our strength in our daily lives. We’ve all heard stories about a man lifting a car to save his loved one. That superpower actually comes from adrenaline, but for it to work fully, it needs to shut down the digestive system and immune response. Then the combination of increased energy levels and increased oxygen levels strengthens our muscles beyond normal. Illustration. We can see with our ears Blind people can walk by using canes or clicking on echoes that tell them about their surroundings. But scientists have actually studied the brain of a blind man named Daniel Kish. He described his vision as “something like seeing the world in dim rays”. So when his brain is being studied, the part that controls his visual context actually lights up as he listens to the echoes that help him navigate by clicking. However, when he was listening to other sounds, the area was pretty quiet. This led the scientists to conclude that Daniel was indeed experiencing something like visions. Illustration. Headaches signal bad weather For some people, headaches are not just a signal that we are too tired or overworked, but also a prediction of the weather. In fact, research has confirmed that a number of headaches, ranging from mild to severe, are caused by weather changes. While for some people it can be a rapid increase in temperature or pressure and usually during a storm. During a storm, warm and cold air mix and create a change in air pressure (barometric pressure). In fact, this is how thunderstorms, rain and wind are created. This type of air pressure actually exerts force on a certain area, and in the case of headaches, this “zone” is you. Illustration. The brain has the capacity to store 2.5 petabytes of memory Our brain has about 1 billion neurons. Each cell makes 1,000 connections with other neurons, a trillion connections in total. This gives the brain about 2.5 petabytes – 1 million gigabytes of storage. If we compare it to the length of a digital video, it would be 3 million hours for TV shows, making the video run non-stop for over 300 years. Embryos can heal mother’s wounds There have been many studies involving pregnant women and their unborn babies. The results of these studies have given scientists a new light on the strength of the fetus. During pregnancy, the cells of the embryo move out through the placenta and reside in different parts of the woman’s body. This can affect the mother’s health. In fact, these cells remain inside the body for more than a decade even after the baby is born. They can help the mother heal from injuries during pregnancy. The human ear has the ability to “hear” molecules Illustration. You can take 2 glasses and pour hot water in one and cold water in the other, and when you do this, you can hear the difference. This is because the molecules in cold water have less energy, producing low-frequency tones while hot water has more energy and produces higher-pitched tones, and we can hear and distinguish well between the two.

Turning on the air conditioner at the right temperature saves electricity Illustration When using the air conditioner, you need to adjust the temperature accordingly. Do not use the air conditioner at too low a temperature, while consuming electricity and harming health. According to calculations, every 5 degrees Celsius reduction, the air conditioner will consume about 40% more electricity. In addition, turning on the air conditioner together with turning on the fan will save 10 – 15% of energy consumption, regularly cleaning the filter, will save 5-7% of electricity. Do not place the device near the wall, as this will waste 20-25% of the electricity. Before leaving the room, turn off the air conditioner about 30 minutes or 1 hour earlier to reduce power consumption and cost of this summer-consuming equipment. Unplug electronic devices when not in use to save energy Illustration According to statistics, many electronic devices such as computers, TVs, sound systems, … still use electricity even when turned off. While these numbers are not high, consider that they consume you 24 hours a day and 7 days a week over a long period of time. Use LEDs instead of Compact lights to save electricity In terms of price, LED bulbs are much more expensive than Compact bulbs due to more modern LED technology. This is considered as one of the factors that make consumers hesitate in choosing to buy products. Illustration However, in terms of long-term economic benefits, LED bulbs will be more economical than Compact bulbs because using LEDs will save energy, significantly reduce monthly electricity costs and repair costs. , replace the ball. Pick up cool air from home windows and doors Perhaps the easiest way is to take advantage of the breeze when the weather is cool. Take advantage of the cool natural breeze, open all windows or doors so that the air can circulate, create a cool space, easily get a good night’s sleep without having to use a fan. or air-conditioning at maximum. Use wall paint, light-colored objects Illustration Color also plays a big role. Light colors are better for reflecting light. You can simply use 1 electric bulb to light up the room. Bright colors also reduce heat absorption and create a softer, cooler feeling for the home. Selection of heat-blocking curtains Illustration Using appropriate curtains will help protect against the sun, prevent heat and minimize the heat and discomfort in the summer. Types with light, fresh, youthful colors such as light green, light yellow, light orange, cream … are very popular. In addition, sunscreen curtains should also be used to reduce heat and block infrared rays.

Even when you are not using it, appliances in your home are still silently consuming energy. You can save up to 35% on your monthly electricity bill by simply turning off and unplugging unused electrical equipment. 2 / Replace light bulbs with energy-saving ones Energy-saving bulbs, such as compact fluorescent lamps and LEDs, use up to 80% less energy than traditional incandescent bulbs and last up to 25 times longer. Although fluorescent lighting may not suit everyone’s taste, there are more and more light bulb options on the market, suitable for most indoor spaces. 3 / Selection of energy-saving equipment By choosing electronics – refrigeration appliances with an energy rating of 3.5 stars or higher and a 4-star water-saving rating on washing machines and dishwashers, you can both save money and save money at the same time. environmental protection. Front load washers use about 50% less water and consume only half the energy of top load washers. 4 / Find and immediately seal leaks You should check your plumbing and faucets at least once a year, especially in the kitchen, bathroom, and toilet. A leaky toilet can waste up to 700 liters of water a day and can easily be missed if you don’t systematically check. 5 / Install motion sensor By installing an external motion sensor, you will avoid having to enter the house in the dark when you come home late, but also without having to leave the lights on before the day. The sensor and timer functions mean you’ll never have to remember to turn the lights on or off again. 6 / Change the shower head in the bathroom Replacing a regular showerhead with a water-efficient one can save you up to 20 liters per minute. Contrary to popular belief, low flow doesn’t mean low water pressure; New showerhead models use air to increase water pressure while still allowing you to conserve water and energy. This is a great option for tenants as you can invest in a quality water-saving shower to use during the rental period, then bring it with you when you move to another rental location./ .
