Does dim light affect mental health?
Spending too much time in dimly lit rooms and offices may actually change the brain's structure and hurt one's ability to remember and learn, indicates groundbreaking research by neuroscientists.
It can improve mood and stabilize our circadian rhythms, helping us get a better and deeper nights sleep. Psychologically, light can decrease depression scores and even increase cognitive performance such as reaction time and activation.
Dim lights strain the eyes and make it harder for workers to focus. These issues can be especially impactful if you have team members working in a dimly lit space, then also staring at bright computer screens all day. The contrast can cause headaches and make it harder for employees to focus or feel comfortable.
Researchers believe that lighting levels make us perceive heat and make us feel warmer, causing our emotions to become more intense. The “hot emotional system” triggered by increasingly bright light can make us feel more strongly about our opinions and feelings. Bright light impacts both positive and negative emotions.
One environmental change that has coincided with elevated rates of depression is increased exposure to artificial light at night.
The impact of ambient light on mood and anxiety is best exemplified in seasonal affective disorder, in which patients experience depression and anxiety in winter when there is less light in the environment.
Natural Light: Natural light is the most effective when it comes to boosting mood. If you don't have enough available, you can install lighting that simulates a natural effect. Attractive Lighting: Attractive lighting can also lift moods. Use lights that fit the aesthetic that you prefer.
Healthcare researchers are also using LED lighting systems to treat depression and other psychological disorders. In addition to suppressing the sleep-inducing melatonin hormone, certain light wavelengths can increase an individual's serotonin levels.
Scientists think nighttime exposure to blue light throws off your circadian rhythm, or sleep/wake cycle. This could lead to symptoms of depression.
Believe it or not, insufficient lighting has been found to contribute to depression and vitamin D deficiencies, while proper lighting is known to improve mood and energy levels. Some studies also show that lighting can affect appetite.
Why does dim lighting make me tired?
In response to darkness, the pineal gland in the brain initiates production of melatonin8, but light exposure slows or halts that production. Drowsiness increases with rising melatonin levels, which is one way that this hormone facilitates sleep.
Darkness causes the molecules to regenerate in a process called “ dark adaptation” in which the eye adjusts to see in the low lighting conditions.
Bright light exposure activates regions of the brain that promote alertness, and improves cognitive performance [3]. Light activates factors that are essential for memory formation [4], as well as factors that are important for the regulation of mood and overall brain health [1].
Research shows that an adequate amount of light improves mood and energy levels, while poor lighting contributes to depression and other deficiencies in the body. The amount and type of lighting directly affect concentration, appetite, mood, and many other aspects of daily life.
A 2017 study reported in the scientific journal PLOS ONE (3) found that blue lighting leads to post-stress relaxation three times as quickly as conventional white lighting. Blue light's potential calming effects have been observed outside scientific studies as well.
Dim light might make it difficult for the eyes to focus, which can cause short-term eye fatigue, says Richard Gans, MD, FACS, an ophthalmologist with the Cleveland Clinic Cole Eye Institute. "But there is no scientific evidence that reading in the dark does any long-term harm to your eyes," Gans says.
By dimming a light, you save up to 98 percent more energy, and up to around 10 percent off your energy bill. Plus, reducing the amount of wattage used by the bulb will cause it to last longer, saving you additional money on light bulbs and reducing the need for more lights to be produced around the world.
New studies reveal that exposure to even dim light during sleep can have adverse effects on the body, potentially causing cardiovascular and metabolic health defects, according to NPR. Even a small amount of light can get through the eyes and affect the brain during sleep, Dr.
Blue light
According to a 2017 study in the scientific journal PLOS ONE (9), blue lighting “accelerates the relaxation process after stress in comparison with conventional white lighting.” This study found that stressed people immersed in blue light relaxed three times as quickly as in white light.
Green – Quiet and restful, green is a soothing color that can invite harmony and diffuse anxiety. Blue – A highly peaceful color, blue can be especially helpful for stress management because it can encourage a powerful sense of calm.
Why does dim lighting make me dizzy?
Several types of environments do not provide enough visual information for your brain and so can result in dizziness and unsteadiness. The most obvious of these is at night when it is dark, or when you are somewhere that only has dim lighting.
Increasing exposure too fast or using the light box for too long each time may induce manic symptoms if you have bipolar disorder. If you have past or current eye problems such as glaucoma, cataracts or eye damage from diabetes, get advice from your eye specialist before starting light therapy.
Morning light provides the most benefit in terms of avoiding circadian disruption that can lead to depression, anxiety, and insomnia.
Light therapy has been the treatment of choice for seasonal affective disorder (SAD)—the gloom that descends on some people as the days grow short. The therapy typically involves spending about 30 minutes a day—usually immediately after waking—in front of a box that emits bright fluorescent light.
Cons of Dark Mode
Dark colors can evoke negative emotions connected with sadness, mourning, or depression. Dark mode may increase eye strain in brightly-lit conditions. Dark mode can cause halation for individuals with myopia or astigmatism, making text less readable for them.
Get an LED Light for SAD
Recent studies have shown that high-quality LED lighting can help treat Seasonal Affective Disorder. The best LED light box for SAD treatment should be safe and have the right color temperature to make you feel better in just a few days.
This creates abnormally high exposure to harmful blue light wavelengths which are much higher than we would receive naturally outdoors from the sun. These high levels of blue light cause an increase in our stress hormones cortisol and adrenaline which leave us feeling highly stressed, irritable, and anxious.
Scientists have now discovered that only when it's really dark can your body produce the hormone called melatonin. Melatonin fights diseases, including breast and prostate cancer. "It turns off the cancer cells from growing," says Joan Roberts, a photo biologist.
One of the benefits of sleeping in a dark room is that it helps you fall asleep easier. According to sleep experts, darkness helps to stimulate the production of melatonin, a hormone that helps you fall asleep quickly. It also helps to keep you asleep until you complete all sleeping cycles.
Science suggests that darkness can do all kinds of things to the human body and brain: It can make us more likely to lie and cheat, make mistakes at work, and even see things we don't normally see. “Darkness is like a mirror: It shows you what you don't want to see.”
What happens when you see dim light?
In dim light the pupils dilate (open wider) so more light can enter. Switch to bright light and the pupils automatically contract. This is the result of a nerve signal generated in the back of the eye triggering the muscles in the iris.
Using dim or red lights before bedtime may help you sleep better. Avoid direct bright light exposure before bed. This will help maintain your natural sleep cycle.
Light itself can cause or trigger migraines based on the brightness, intensity, the type of light, and especially if the light flickers. It's estimated that 80-90% of people who suffer from migraines also experience painful sensitivity to light—a symptom known as photophobia.
HARMS OF TOO DIM BRIGHTNESS: If the brightness of your gadget is too low, you will end up straining your eyes. This happens because you may have to focus a little strainfully. Although, this will not cause any long term damage but can lead to headaches.
Serra A study found brightly lighted rooms heighten emotions more than dimly lighted ones. The study suggests bright light induces an illusion of warmth that intensifies a person's positive and negative responses.
So, while brightness itself is not a concern for eye health (unless you're staring directly at the sun!) having your brightness set to a level that is more comfortable for your eyes, can also reduce the amount of blue light, which will protect your eyes from phototoxicity.

If people are exposed to light in the morning that mimics the wavelengths of daylight, they become better at coping with anxiety-provoking experiences. The light simply improves the communication between the regions of the brain that are central to our handling of emotions such as stress and anxiety.
Participants with anxiety disorders are affected by the fluorescent light. They feel uncomfortable and would prefer to either leave the place with fluorescent light or try to adapt to the situation. Also, fluorescent light reminds anxiety participants of negative aspects more than healthy participants.
Their stress responses showed that a bright light exposure increased the stress hormone level greatest compared to dim white, red or blue light sources. Findings point toward the crucial role of light intensity associated with the hormonal stress response.
Dim lighting is usually associated with relaxation, and winding down after work. But scientists now claim that by harnessing the subduing effect on emotions caused by dim lights. Therefore, by dimming the lights, people become more rational, negotiate better and are therefore able to make better decisions.
What color is good for depression?
Red. A very powerful color, red can easily raise energy levels and stimulate moods. Because of its power, it can help combat depression by creating positive thoughts and feelings.
New research claims that dark blue is the world's most relaxing colour. Research carried out by the University of Sussex and paper company G.F Smith, draws on a survey of 26,596 people, from more than 100 countries.
The sunny yellow color of the sun and spring flowers directly translates to joy and happiness. For this reason, yellow light has been clinically used to treat depression and Seasonal Affective Disorder (SAD). You might try switching your LED lights to a yellow hue during the dark winter months and when you feel down.
The visual aesthetic of low-key lighting is usually achieved by using hard sources or key lights with minimal to no fill light. Low-key lighting is often used in thrillers, dramas, and horror films because of the mysterious, dark, and dramatic mood the style creates.
Dim light might make it difficult for the eyes to focus, which can cause short-term eye fatigue, says Richard Gans, MD, FACS, an ophthalmologist with the Cleveland Clinic Cole Eye Institute.

Dim lighting can help you get a good night's sleep.
During the absence of light, our retinas' light-sensitive cells immediately tell our brains that it is time to rest and hibernate. Consequently, our pineal gland starts producing melatonin, also known as the sleep hormone.
"Blue lighting accelerates the relaxation process after stress in comparison with conventional white lighting," the researchers confidently declared. "The relaxation time decreased by approximately three-fold."
Bright light exposure activates regions of the brain that promote alertness, and improves cognitive performance [3]. Light activates factors that are essential for memory formation [4], as well as factors that are important for the regulation of mood and overall brain health [1].
They are often used in homes and businesses to conserve energy and to control the lighting environment. Dimmer switches can be hooked into your smart home's functions for controlling the ambiance in your home.
What does it mean when someone dim your light?
Dimming Your Light Is Insulting
Many of us are taught to dim our light so not to appear conceited or stuck up. The truth is, by dimming your light to make others comfortable you are insulting the other person. For instance, whether you realize it or not, people can see how brightly your light shines.
An area of dim light is usually a boundary between a source of bright light, such as a torch, and surrounding Darkness. The soft light of twilight and dawn also counts as dim light. A particularly brilliant full moon might bathe the land in dim light. Darkness creates a heavily obscured area.
