Certain light colors interfere with your body’s production of melatonin, the hormone that regulates your sleep cycle (7). Your brain works differently as lighting colors change.Suffice it to say that lighting plays a major role in your sleep cycle and patterns. Dim lighting (6), on the other hand, can tell your brain that it’s time to sleep. Bright lighting, whether natural light or artificial light, is often associated with higher energy levels, exactly the opposite of what you need for sleep. You react to brightness levels while you’re awake.As your retinas detect increasingly more light, like when the sun rises, they alert a part of the brain called the hypothalamus – essentially the body’s clock – to gradually awaken you. Even when you’re asleep, the retinas of your eyes can detect light (5). There’s a reason people are inclined to sleep when it’s dark, and it’s difficult to sleep during the daytime hours. While it’s well known that darker rooms often lead to better sleep, lighting – as in, not complete darkness, but certainly not daytime levels of light – can help too. That’s why sleep is correlated with easier problem-solving, sharper memory, and clearer thinking. Proper rest is crucial for cognitive ability. When you sleep well, your mental functions improve (4). And when you’re feeling better, making good decisions, and always in the zone, you’re likely to be less stressed (which, in turn, means you’ll sleep better (3)). The restorative processes (2) that the body works through during sleep may lead to sharper concentration, stronger positive emotions, and better decision-making. Other reasons sleep is so important include: We all know that sleep is important – it’s how our bodies recharge (1) and heal, it’s how we ensure our brains work at full capacity, and it’s something that we quite literally can’t live without. Read on to learn the best – and worst – light colors for sleep. ![]() Instead, you might get better sleep from keeping certain colored lights on while you sleep. No, we’re not saying you should turn on your daytime artificial white or off-yellow light when it’s time to go to bed. But what if you tried something different and kept some light on instead? ![]() That doesn’t mean you always get it – and with the grogginess that you feel the next day, you certainly won’t forget about your poor sleep. Every night before going to sleep, you turn off your lights, close your eyes, and hope for a good night’s rest.
