12 Little Tweaks That Will Make Your Work Environment Better

Decreased sun exposure can cause your serotonin levels to drop, which can in turn leave you feeling sleepy and stressed. So, open up those office blinds — and make sure that there is no furniture blocking out the sunshine. (Just make sure that the sun isn't causing a glare on your monitor or causing strain in your vision.)

If there's not much natural light to be had, put a lamp that mimics natural light on your desk. You should also go out from time to time to get your much-needed sunlight exposure. (Though don't forget to wear sunblock!)
