How to Create the Healthiest Indoor Space (Including Lighting and Ventilation)

In recent years, there has been a growing awareness of the importance of living in a clean, safe environment. The air we breathe in our homes and workplaces can drastically affect our health and wellbeing.Pollutants such as dust, pollen and viruses can sneak into our homes at any given minute and cause a host of illnesses. If you’re reading this article, you may be wondering how to create a healthy living space for your loved ones. Below, we’ll look into how you can create a healthy living space in your home generally, and also through using the right lighting and ventilation systems.How to create a healthy living space So, generally speaking, how do you go about building a healthy indoor space? Here are the steps you need to consider:1. Personalise your living spaceWe spend most of our lives inside. So it’s absolutely essential to select an indoor space that reflects who you are. Whether you’re working from home, lounging around or having guests over, it’s those personal touches that really makes home a home.You can personalise your home by placing pictures and furnishings you love around the home, particular fabrics you like and ornaments you’ve collected throughout your travels.2. Purchase houseplantsWhy leave the great outdoors … outdoors? You can bring the outdoors into your home! Invest in a variety of quality houseplants to make your home feel a little more natural. Houseplants come in all different shapes and sizes, so there’s truly no limit here.Having plants around the home can also purify the air around you, so everyday you can breathe a little better, knowing that less toxins are circling in the air you breathe.3. Take advantage of lightingEvery home needs a good lighting source, whether that’s through natural light or artificial light. Lighting has been known to alter mood, and can transform negative vibes into positive ones. Having a home full of bright light can help lift your spirits and keep you feeling amazing.Below, we’ll look into how you can use lighting to create a healthy living space in more detail, so stay tuned.4. Invest in a ventilation systemSelecting the right ventilation system that’s appropriate for the size and layout of your home is a critical first step. It is important to ensure that the system you choose has sufficient airflow to effectively remove stale air and pollutants from your home.The ECO dMEV (Decentralised Mechanical Extract Ventilation) system, for example, is a ventilation system that uses fans to extract stale air and moisture from a particular room and replace it with fresh air. These systems are designed to be decentralised, meaning that they are installed in individual rooms rather than being centrally located. Traditional ventilation systems rely on natural airflow to circulate air throughout the building. This can be difficult to control, particularly in larger buildings with multiple rooms. ECO dMEV, however, offers more control over airflows, as each room has its own fan that can be adjusted to suit its specific requirements. This means that air can be directed to where it is needed most, ensuring that all areas of the building receive adequate ventilation.How ventilation systems can help you create a healthier living spaceVentilation systems offer several benefits, including improved air quality, increased energy efficiency, and better control over indoor airflows. We’ll outline some of these benefits in more detail below.1. Improved air qualityPoor indoor air quality can lead to a range of health problems, including allergies, respiratory issues, headaches, and fatigue.Ventilation systems can help improve air quality by extracting pollutants and moisture from the air, reducing the risk of health problems. They are designed to run continuously, ensuring a constant supply of fresh air throughout the home.2. Remove condensationCondensation is what happens when the air reaches a certain level that it no longer can hold in moisture. That’s why we see our windows and mirrors ‘condensing’.The problem with this is that it is responsible for creating mould throughout the home, which can lead to nasty smells and even health issues. A robust ventilation system can help you eliminate that condensation, converting a stagnant atmosphere into a fresh and healthy one.3. Alleviate hay fever symptomsHay fever, also known as allergic rhinitis, is caused by an allergic reaction to airborne allergens such as pollen, dust, and mold spores. These allergens can accumulate in indoor spaces and trigger hay fever symptoms.Ventilation systems can help reduce the concentration of allergens in indoor air by increasing the circulation of fresh air, in particular by exchanging indoor air with outdoor air. This can dilute the concentration of indoor allergens and is particularly important during peak allergy seasons when pollen counts are high.How to use lighting to create a healthy living spaceIn 2021, a systematic review was conducted on papers discussing the impact of lighting in the home on the health of the inhabitants. It was clear that poor lighting can negatively affect people's health and that lighting in general is a key aspect of housing quality.Home lighting affects both the aesthetics and functionality of a home, and can have a significant impact on mood, productivity, and overall well-being. Adequate lighting helps people regulate their normal day-to-day activities and is important for keeping the home safe.Below, we’ll outline how you can use lighting to create a healthier living space in your home.1. Consider natural lightNatural light is an excellent source of illumination that can improve mood and well-being. Consider installing large windows or skylights in areas that can receive natural light to help reduce the need for artificial lighting during the day. Just make sure to have UV-protective films installed to prevent sun damage.2. Use energy-efficient lightingEnergy-efficient light bulbs and fixtures will help you reduce energy consumption and lower energy bills. LED bulbs are a good option for home lighting as they are long-lasting and consume much less energy than traditional incandescent bulbs.3. Install lighting controlsLighting controls, such as dimmers and timers, can help regulate the amount of light in a room and reduce energy waste. They can also help create a more relaxing and comfortable atmosphere.4. Layer lightsLayered lighting can create a more comfortable environment that's suited to your specific needs. Experiment with a combination of ambient lighting, task lighting, and accent lighting to find what your body needs for the day.Looking for more ways to create a healthy living space at home?Now that you know how to create a healthy living space, you can be confident that you know what to look for in choosing your lighting fixtures, bulbs, and home ventilation systems.By taking into account the size of your home, your needs for different rooms, and the types of lighting you require, it is highly possible to create a healthy indoor space that allows you to thrive while promoting your well-being.Here at Sparks Direct, we are committed to contributing towards healthier living spaces with the ECO dMEV, offering continuous ruling ventilation for the home, as well as a vast selection of energy-efficient LED lighting and Dimming systems.

Poor ventilation leads to old, moist air lingering as condensation on your walls and furniture. This, in turn, causes dampness and mould - not exactly the most appealing of house features.Fortunately, you can now keep dampness at bay with a reliable ventilation system. Continuous ventilation systems are ideal for home use since they allow you to keep your entire area well-ventilated without any hassle.What is ECO dMEV? ECO dMEV is a type of ventilation system used in residential buildings. The ECO dMEV ventilation system is typically installed in individual rooms, such as bathrooms, and is connected to ductwork that runs to an external vent. The units are designed to be easy to install, use, and maintain, and are often used as a more energy-efficient and cost-effective alternative to traditional mechanical ventilation systems in residential buildings.The ecological operation of the ECO dMEV units is achieved by reducing energy consumption and noise levels, as well as providing a higher level of indoor air quality.What does ECO dMEV stand for? The term "ECO dMEV" means "Decentralised Mechanical Extract Ventilation with Ecological operation". It is a low-energy and low-noise ventilation system that is designed to extract moisture, pollutants, and stale air from kitchens, bathrooms, and other wet rooms in a home or office. ECO dMEV units operate continuously and use low-energy, DC (direct current) motors to extract air at a constant rate, which helps to maintain good indoor air quality and prevent the buildup of harmful substances, such as mould and mildew.Mechanical extract ventilation (MEV) is designed to supply air continuously at a low rate. It works by extracting air at multiple points to simultaneously draw moisture out from rooms, particularly wet areas such as bathrooms and kitchens. MEVs are more efficient compared to installing separate fans in each room.How does the ECO dMEV ventilation system work? ECO dMEV is a decentralised mechanical extract ventilation system designed to remove moist and polluted air from individual rooms, such as bathrooms and kitchens, in residential buildings.Installation and connectionThe ECO dMEV unit is installed in the room that needs ventilation, typically in the ceiling or wall, and is connected to a duct that leads to an external vent. Each contains a DC (direct current) motor, which powers a centrifugal fan that extracts air from the room.Extraction of airOnce the unit has been properly installed, it continuously extracts air at a low and constant rate, which helps to maintain good indoor air quality and prevent the buildup of moisture and pollutants that can lead to health problems and possibly destroy your furniture.VentilationECO dMEV continuous ruling ventilation for the home has a humidity sensor and a timer that can be programmed to increase or decrease the ventilation rate based on the level of humidity in the room or the time of day.It is designed to be energy-efficient and cost-effective, using only a small amount of electricity to operate, and operating quietly and unobtrusively. Perfect for those peaceful afternoons at home.What are some advantages of the ECO dMEV continuous ventilation for the home?Continuous ventilation systems, such as ECO dMEV, have several advantages over intermittent ventilation systems as follows.1.

How Ventilation can help Tackle Allergies, Asthma, Hay Fever, and Pet Dander

Asthma is a long-term condition that affects your airways, which transport air in and out of your lungs. Sufferers of asthma have sensitive airways that are inflamed and ready to react when they come into contact with certain airborne particles. When asthma is triggered there will be a varying degree of symptoms. These include the tightening of the airways, so they become more narrow. The lining of these airways will become inflamed and start to swell. This will cause mucus or phlegm build up, further narrowing the airways. This is a very serious ailment that can be fatal, in cases of serious asthma attacks. Three people die every day due to this condition. More people die each year due to asthma than cervical and testicular cancer combined. There is no cure for asthma as of yet - only preventative measures, such as asthma inhalers and medicines. A hugely important role in preventing asthma attacks is identifying what causes them and eliminating these threats. This is partly achieved with quality ventilation that keeps an environment of clean air around sufferers of asthma. There are other serious allergies that are aggravated by poor quality air such as hay fever, eczema and pet dander. In this article, Sparks will examine how ventilation manufacturers have sought to help with the devastating problems caused by asthma and other allergies.What triggers asthma attacks? Practically any airborne particles that irritate the airways can trigger asthma. These can differ from person to person. Certain asthma sufferers will be more susceptible to triggers than others. There are many common causes of asthma triggers around the house. These include: House dust mites. Tobacco smoke. Animal fur. Mould and fungi. Pollen. Humid, dry air. Stress. There are preventative measures needed to stop these triggers, which include medicines, lifestyle advice and avoiding the triggers altogether. When looking at the list of main factors that cause asthma attacks, it is clear good ventilation is probably the best preventative measure. How ventilation can help prevent asthma and eczema: tackling dust mites Dust mites are the primary trigger for asthma sufferers. Researchers estimate they may cause up to 80% off all asthma attacks, as well as countless cases of eczema. Eczema is a condition that causes your skin to become itchy, red, dry and cracked. It is a chronic condition for most people who have it. As you may be able to infer from their name, dust mites thrive in dusty, unclean environments. Their main breeding ground is in unwashed bedding and unclean carpets. Their only source of water is from the air so they can only live in areas where humidity is relatively high. The higher the levels of humidity, the easier it is for them to breed. The fastest and most efficient way to reduce the population of dust mites in your home is by providing great ventilation. Envirovent sells a range of ventilation systems for all areas of your home. They are best situated to combat dust mites anywhere where there is bedding, curtains and carpets. Their ventilation systems provide constant fresh air to decrease humidity levels within the home. Controlling dust mite population will help asthma and dust mite sufferers alike breathe far easier. There are other simple methods for getting rid of dust mites: Wash your bed linen every week at 60 degrees. Use specially designed 'allergy' covers for your pillows, duvet and mattresses. Clean and vacuum your home on a regular basis. Allow fresh air in through the windows Consider installing a whole house ventilation system to supply a continuous source of fresh, filtered clean air. By keeping your home well ventilated you are driving humidity levels down. This decreases the dust mite population of your house: a strong step in tackling asthma and eczema triggers. How ventilation can help tackle hay fever Hay fever is a widespread allergy which affects approximately 1 in 5 people in the UK and is caused by an allergic reaction to pollen in the air. Hay fever is normally associated with grass or hay pollen, the most common being grass pollen. Grass pollen tends to affect people each year from late spring to early summer. Of course, grass pollen is not the sole cause of hay fever by any means. Tree pollen usually triggers reactions in sufferers from early spring to late spring. Meanwhile, nettles and docks (weed pollen) pollinate from early spring until early autumn. This means summer is not an exclusive season where hay fever symptoms may hit. Due to its seasonal nature. hay fever is also known as seasonal allergic rhinitis. It is made more manageable than asthma as its triggers can be predicted by the time of year. The main symptoms of hay fever are: An itchy nose. Watering eyes. An itchy throat. A blocked nose. Unusual amounts of sneezing. Headaches. An aching face. The symptoms will vary from person to person, and some sufferers may have it ‘easier’ than others, for instance, if they only get watering eyes and a slightly blocked nose. However, for others, the symptoms may be so severe that they will affect their sleep patterns and interfere with their education or work. The main demographic affected by hay fever are children and teenagers. Thankfully, much of the time the condition improves or simply goes away. Unfortunately, if you have one allergy you are more likely to suffer from others. If you have asthma or eczema, there is an increased chance you will develop hay fever (and vice versa). A reliable factor in combating hay fever is the same for asthma and eczema: quality ventilation. Check out Envirovent’s Silent: a range of quiet, eco-friendly extract fans that can placed virtually anywhere indoors. How ventilation can help tackle pet dander Over half the UK’s households have a pet. Unfortunately, allergies to our furry friends are very common, as there are 4.8 million estimated sufferers in the UK. ‘Pet dander’ describes the dead skin cells which animals naturally shed from their bodies. The flakes of skin are triggers which can cause an allergic reaction in some people. Those who are allergic to pet dander often suffer from the following symptoms: Itchy eyes. Constant sneezing. Nasal congestion. Wheezing. Pet allergens are tough to deal with due to their shape and size. They can easily embed themselves in bedding, fabrics and furniture. The following precautions may help with pet dander: Replace carpets with laminated or hardwood floors. Switch curtains for blinds. Make areas such as your bedroom ‘pet free zones’. Always wash your hands after interacting with your pet. Regularly clean the rooms where your pet sleeps. Keep your home well-ventilated and do not allow dust to accumulate. How to prevent ‘Toxic Home Syndrome’ impacting your health Professional Electrician published an article on all these pollutants, which can combine to cause ‘Toxic Home Syndrome’. They advised on Mechanical ventilation with heat recovery (MVHR) as a ‘whole home’ solution. They also recommended de-centralised mechanical extract fans (dMEV) as a: quiet and unobtrusive ventilation option (that)… extracts moist air that causes condensation and mould, and replaces it with clean, fresh air that is circulated internally. Both MVHR and dMEV solutions are available through Sparks, including Envirovent’s many efficient ventilation products.
