Notes

The Barents Sea is a shallow basin of the Arctic Ocean. It is located north of the shores of northern Europe and it is the stretch of water one can admire from North Cape. It is notoriously difficult to cross because of the weather and the currents that often create unfavorable conditions for navigation, but it is also a very important area for ship traffic, fishing and oil and gas exploitation.

Notes

[Disclaimer: This episode does not constitute medical advice] Winter and darkness have effects on people everywhere but living in the polar areas exposes the population to more extreme conditions with the drastic reduction or absence of sun exposure. The effects of not being exposed to a constant or nearly constant day/night cycle may cause winter depression/blues also called Seasonal Affective Disorder or SAD that result in disruption of circadian rhythm with sleeping trouble, low energy and low immune function.

It is not well known what are the physiological bases of SAD, but it may be caused by low serotonin levels. Also the melatonin cycle plays a role in regulating the biological clock and is influenced by changes in daylight. Another factor that may contribute to the insurgence of the syndrome is [vitamin D](

In order to boost vitamin D one may want to resort to a targeted diet (including fatty fish, mushrooms, eggs) or treatment with special SAD Lamps. Some mammals are better adapted than others to living in the low light conditions in the Arctic: Video
