▲The relation between darkness and depression is well-known. According to Scientific American, a 2007 Proceedings of the National Academy of Sciences study highlighted the consequence of being deprived of natural light.

▲Light is important for mood stability. The 2007 study confirms the prevalence of Seasonal Affective Disorder in places where there is limited natural light.

▲Neuroscientists at the University of Pennsylvania kept rats in the darkness for six weeks. The animals developed depressive behavior and damage to the brain region that is associated with depression.

▲During that experiment, scientists observed that the rats' neurotransmitters associated with emotion, pleasure, and cognition were dying.

▲According to the Scientific American, researcher Gary Aston-Jones said that light deprivation leads to a rupture of the body's internal clock, which could eventually lead to changes in the brain regions that control mood.

▲Several studies and experiments have demonstrated that the body's natural rhythm and circadian cycle depend on natural light.

▲When we see light, our body automatically assumes it's time to wake up. In darkness, our brain releases melatonin, which allows us to sleep. It becomes a problem when the body thinks that it is always time to switch to sleep mode.

▲The side effects of constant darkness include insomnia, anxiety, bad mood, and a state of lethargy.

▲Many people in Nordic countries suffer from Seasonal Affective Disorder and depression.

▲One of the best ways to fight depression is to work out in the morning. It improves mood and energy levels.

▲According to website NetDoctor, Sue Pavlovich from the Seasonal Affective Disorder Association states that one should spend at least one hour a day exposed to sunlight. A good way to fit this into your busy life is to spend lunch hour outside.

▲Some of the symptoms of depression you should look out for are: a feeling of helplessness, lost of interest in everyday activities, a change in appetite or weight loss, irritability, lack of energy, and concentration problems.

▲If you feel like the only way to get rid of the feelings of despair and loneliness is through suicide, it is extremely important that you seek help.

▲Some people suffer from Seasonal Affective Disorder due to a limited exposure to sunlight in the winter. According to the Help Guide, 1 to 2% of the world's population suffers from this disorder.

▲In some Nordic countries, artificial lights are used as treatment for people suffering from Seasonal Affective Disorder.

▲It is common to find these devices in Nordic homes. They provide heat, light, and a taste of the spring/summer climate.

▲Seasonal depression affects people mainly when the days are shorter and sunlight is limited.

▲People tend to spend more time at home, and this isolation can also lead to sadness.

▲If you live in a place with this type of climate, there are somethings you can do to improve your mood and general well-being.

▲Try to interact with people as much as you can, especially when you feel alone. Reach out to your friends and make fun plans.

▲Sometimes, all you need is a good listener who cares about you.

▲Follow a balanced diet. Swap the foods that may be affecting your mood such as those containing caffeine and alcohol for healthy, nutritious options.

▲Work out! When you're feeling blue it's hard to get up and exercise, but try going for a walk or gentle workout. Exercise is a natural antidepressant.

▲Find a hobby that you truly enjoy, volunteer, or get a pet! These things will keep you busy and help you to feel better.

▲Do not feel ashamed of seeking help. If you feel like there is no other way out, get yourself some professional help.

▲Most people take natural light for granted, but people who live in Nordic countries don't. Sunlight deprivation can have effects on the human body and mind, and can even lead to depression.
