Does Natural Light Affect Our Health?

Us humans need sunlight in order to thrive and be happy in life. Natural light causes our bodies to absorb Vitamin D, which us in the UK can suffer from deficiency sometimes, due to our ever changing weather. But maximising our exposure to natural light both outdoors and whilst indoors too is one of the best things we can do for our mental health.

How can you solve a natural light deficiency?
In many homes, it can be difficult to find ways to get enough natural light, especially if you live in house that were designed years ago when day light wasn't a focus in the building design. To combat this, you can put in a few cheap windows to add some natural light in places that can usually be dull. and where you need natural light the most.

In our work focused modern day lives, it can be so easy to forget about caring for our mental health. But just one thing, such as getting that extra day light, can improve our mental health in many different ways...

Serotonin is a key chemical in our bodies that sends our brain important signals to regulate our mood. So, it's no surprise that we feel happier and more alive on sunny days, and when we've been outdoors for extended periods of time. Sunlight exposure has everything to do with this and a lack of serotonin is linked directly with depression and anxiety disorders. It's common for people to experience seasonal depression in the colder months, as it is harder to get outside with less sunlight.

I know this one all too well. Winter comes over, the dark days arrive and I lose all my concentration when it comes to writing. I just can't focus, at all. I guess, if you spend all day in a dimly lit home with artificial lighting, it can cause us to get distracted far easier. When working indoors, or at home, like me, getting natural light can be hard, and that can effect our focus levels.

Proper exposure to daylight helps us maintain a healthy appetite. The Vitamin D that we get from sunlight is a natural appetite suppressor, and serotonin can minimise junk food cravings. This is because sweet foods and carbohydrates can temporarily raise serotonin levels, that's why you get the cravings when your levels are low. 

Again, serotonin seems to come in to play here too. The amount of serotonin we produce in the day correlates with the amount of melatonin we produce at night, so if you're not getting enough during the day, you might find yourself struggling to catch some zzz's at night. 

So, you might not think that natural light can do much when it comes to our health and wellbeing, but you'd be so wrong. Natural light can help in so many aspects of our daily lives, so it's important to maximise the amount of time you are getting exposure to natural light, indoors and out to keep your health in tip top condition. 


  1. we have one large (ish) window in our front room, but it is a long room, so it does not produce much light, but the bedrooms let alot of light in

  2. Without a doubt ! Even getting outdoors in the daylight has a big impact

  3. I always feel sadder in winter think its the same for a lot of people

  4. light is very important, I loathe dark dull days of winter, just seeing a bit of daylight or sun outside really lifts the mood.
