This is unexpected.

When it comes to lighting up your home, it's unlikely that you'll give it much thought. Your biggest concern is probably whether you'll buy energy efficient ones or not. But some research is leading people to believe that light bulbs can have a serious affect on your health. While many of use focus on what we're feeding our bodies it is also important to take into account what type of light we are feeding our eyes. NHS reports that not experiencing the right quality of light could have adverse effects on hormonal changes, sleep patterns and may even be linked to obesity. At the time, the researchers found a significant link between light levels in women's rooms at night and their risk of being overweight and obese. The researchers speculated that melatonin, a hormone whose production is inhibited by exposure to light, could play a role. This hormone plays a role in your metaboslism so if it is affected by light it could be affecting your body too. Overexposure of our eyes to light can prevent melatonin secretion and can have unfavourable effects on other bodily functions. While the study could didn't exactly prove that light was causing a difference in obesity risk, those carrying out the study described their results as "intriguing". Regardless of whether it has an affect on weight, it can have an affect on sleeping patterns. While bright light can be good in the morning to wake you up and keep you alert, too much exposure to a bright light-bulb at night time can keep your brain alert, making it difficult for you to sleep, which in turn can result in various negative reactions. The best thing to do is get yourself a dimmer switch which you can turn way down in the evenings, or chose one that isn't quite as bright, and keep the curtains closed when you go to sleep to avoid natural light spilling in to disturb you.
