PROUD SPONSOR OF DOORS & WINDOWS DOORS&WINDOWS How rooflights can benefit health » » ROOF MAKER PIONEERS THE manufacture of high-performance glass units in overhead glazing structures. The company has released information that explores the surprising benefits of natural light, mainly from sky lights, on our health. Rooflights provide a number of health benefits because they provide natural ventilation and let the sun flood into a home. TREAT SEASONAL AFFECTIVE DISORDER Not getting enough exposure to sunlight is thought to contribute to Seasonal Affective Disorder (SAD, also known as winter depression, which is estimated to affect about six per cent of the UK population. Lack of sunlight may lead to changes in brain chemistry, such as lower serotonin levels, which is linked to depression. REDUCE THE RISK OF DEVELOPING CANCER AND DIABETES If you don’t get enough natural light at the right times during the day, your body clock can be disrupted, which can affect your sleep. In the long term, this can lead to heart disease, diabetes, cancer and mental illness. STOP INFECTIONS FROM SPREADING Natural ventilation can help prevent infections like the common cold from spreading by diluting and dispersing the microbes which cause them. Rooflights with electric openings are great for providing natural ventilation. DEVELOP HEALTHY EYESIGHT IN CHILDREN Short-sightedness is increasing at an unprecedented rate and could affect one third of the world’s population by 2020. A lack of sunlight is thought to possibly be contributing 60 » N OV 2017 » CL EARVI E W- UK . C O M to the phenomenon, particularly in children, by disrupting the production of dopamine which helps the eyes develop properly. MINIMISE ALLERGY SYMPTOMS Mould thrives in poorly ventilated conditions and can trigger allergy and asthma symptoms. Improvements in natural ventilation are estimated to reduce lung- related illnesses by up to 20 per cent. LOWER BLOOD PRESSURE The sun helps lower your blood pressure by causing your blood vessels to widen when it hits your skin. High blood pressure is a risk factor for developing heart disease, so research is underway into whether sunlight can help. REDUCE INDOOR AIR POLLUTION Mechanical ventilation, such as ceiling fans, can lead to a build-up of indoor pollutants released by cleaning products, paints, air fresheners, furniture and office equipment like printers. This can irritate the eyes, nose and throat and cause headaches, dizziness and tiredness. An opening rooflight provides natural ventilation and is a great alternative to air conditioning. STRENGTHEN YOUR IMMUNE SYSTEM Opening the window to allow the sunlight to hit your skin directly helps your body make vitamin D, which has all manner of health benefits from strengthening your immune system to keeping your bones strong. DID YOU KNOW • Rooflights let in up to three times more natural light than standard windows. • The sun’s UV radiation is made up of different wavelengths (UVA, UVB and UVC) which affect the body in various ways. Only UVA and UVB reach the earth and affect parts of the body like the eyes and skin. UVA makes up about 95 per cent of radiation which reaches earth. • Indoor lights are not bright enough to give you the health benefits you get from natural light. Brightness is measured in lux and a normal light bulb only has about 250 to 500 lux, while sunlight has between 50,000 to 100,000 lux.
