Why We All Need Natural Sunlight In Our Lives


Most of us know the risks of too much unprotected sun exposure, but did you know too little natural sunlight could have an impact on your health as well? It's true: Getting too little sun can cause a cascade of physiological changes in your body that can make you feel tired and depressed and even lower your immune system, making you more vulnerable to disease.

The Sunlight Advantage

Sunlight has an amazing range of health benefits for your body. Several studies have demonstrated the link between natural sun exposure and lower levels of depression, and one “type” of depression - Seasonal Affective Disorder, or S.A.D. (the Winter Blues) - is directly related to exposure to natural sunlight. Other benefits include:

Immune System Booster

Sunlight has also been shown to speed healing and boost immunity by increasing production of white blood cells, and it can even decrease pain following surgery and in patients with chronic medical issues. Sunlight has an important role to play in defending your system against common infections.

Sleep Like a Baby!

Exposure to sunshine can help boost your energy levels by regulating our natural sleep-wake cycles – the circadian rhythms – to help our bodies function at peak performance. Sleep disorders often arise due to a lack of sunlight exposure. Sufferers often complain of irregular sleep patterns, mood swings, and lack of workday productivity. Natural light synchronises the brain’s melatonin levels, bringing balance to your life.

General Health

Sunshine exposure can also help suppress appetite via hormonal stimulation, assisting weight loss and helping us feel more energetic throughout the day. Sunlight exposure on skin can create a smoother complexion whilst assisting with skin disorders such as eczema and psoriasis. Improved blood circulation via sunlight increases nutrients and oxygen in your red and white blood cells. This in turn stimulates a lower heart rate and reduces blood pressure.

Fight Disease

Sunshine affects the body in lots of beneficial ways. In fact, regular exposure to natural daylight is essential for the production of vitamin D, also known as the ‘sunshine vitamin.’ Vitamin D intake is necessary for maintaining healthy bones and muscles, and even for preventing diabetes, multiple sclerosis, and internal cancers like colon and kidney cancer. Some studies suggest getting enough vitamin D also increases cancer survival rates. While we get some vitamin D in foods, most of the vitamin D comes directly from direct sun exposure, as our bodies convert the sun's natural energy into a form of vitamin D that can be used by the body.

Vitamin D from the sun also helps prevent osteoporosis (brittle bones) and heart disease, helping promote lower levels of cholesterol and reducing blood pressure. It must be noted that Solatube Daylighting Systems successfully block Ultra Violet Rays (UVB and UVC) that fall within the 100-315 nanometre range. This means that Solatube Daylighting Systems do not transfer the required UV light for vitamin D production within a room. For that, you’ll have to take a healthy walk!

Bringing the Sunshine Indoors

Bringing natural sunlight into dark interior spaces is a great way to get more of the sun's benefits in smaller, regular doses for a long-term effect that can have a big impact on your physical and mental health. Windows only bring in light to a very restricted area near the exterior walls of a home, and then only during brief portions of the day when the sun reaches a certain angle.

A Solatube daylighting system uses Raybender 3000 technology to draw daylight into the tube whenever the sun is shining, even on cloudy days, and combined with the patented LightTracker in-dome reflector it assists in redirecting low-angle sunlight, perfect for those shorter days. The light is directed into your home through the special Spectralight Infinity tubing, the highest reflective material in the world. Solatube’s tubular skylights use diffusers to evenly distribute light across your room, even into the darkest corners. Moreover, Solatube's proprietary design eliminates hot spots while still flooding your home with plenty of healthy light. Solatube's slim design is easy to install and strong enough to carry daylight all the way to the darkest recesses of your home, including the basement.

Beyond the health benefits, bringing more daylight indoors also reduces electricity bills and minimises your impact on the environment, making a Solatube an all-around winning solution. To learn more about Solatube, browse our website or contact us.
