Vitamin D is one of the essential nutrients required for the body to remain healthy, and the skin to remain fresh. It is often gotten from direct exposure to early morning sun rays. As for submariners, they are usually under water. They may unable to get exposure to direct sunlight. How then do they get their vitamin D? In this article, we will be discussing whether or not the lighting on submarines is often designed with the vitamin D necessities of the crew as a primary concern.
In the 1970s, submariners often utilized general fluorescent lights. Although, the fluorescent were heavy light bulbs capable of maintaining lighting if there should be an occurrence of depth charging, impact, or any other form of mechanical shock. Also, there were mechanical charge clips used to lock each and every bulb in place. This would help prevent them from rotating.
Furthermore, they were likewise mounted in plastic sleeves, to hold together the pieces in the event that they break. The point is that they were simply standard fluorescent lighting, some radiant knobs for the direct current backup lighting. This might be tended to on more current water crafts yet just a recent or current crewmember can tell you.
In addition, a couple of new LED light systems were just recently launched by the International Space Station (ISS). These features controlled outputs of blue and red wavelengths. They have been designed so as to help in keeping people awake. They also assist them in falling asleep.
In case these tests turn out to be fruitful, the innovation might be embraced on submarines to help in keeping everybody throughout the day. Be that as it may, this may make things more troublesome for the individuals who need to work during the evening and additionally work a six on twelve off shift.
In conclusion, the wavelengths can be adjusted to give enough UVB to create vitamin D. From the report says it was noticed that six days of exposure to UVB having vitamin D supplements is enough to compensate for about 49 days with no daylight. Perhaps lamps can be installed in the lounge of the crew. With this, they will have the opportunity of soaking up some rays during off time periods. For now, the only means of getting Vitamin D for the crew is strictly by supplements.
