Night Work


Night work

The circadian rhythm is created by our brain´s "internal clock", and is affected by light which strikes the retina. The internal clock regulates the production of melatonin, which is our sleep hormone, produced by the pineal gland during the night. If the internal clock is exposed to light at night, the production of melatonin is suppressed. People who have a normal circadian rhythm are awake during the day and sleep at night. This is changing every year in our modern 24-hour society.

Combating fatigue when working at night is much due to that the natural melatonin production is highest when it is dark outside. People who work at night usually need about a week to return to normal circadian rhythm, which then occurs on their days off.

Cure for fatigue

A combination of sleep glasses and light therapy can help night workers to regulate their circadian rhythms and sleep patterns so that they get a quality sleep, both before the nights they will work but even before their days off.

For example, if you work 9:00 p.m. to 6:00 it’s a good idea to get light therapy before coming to work, then the body thinks that it should be awake. Moreover, it is a great advantage if possible, to continue exposure to bright light while you work. The strong light keeps you awake because it contains the blue light that inhibits the production of melatonin, the body's natural sleep hormone. When your night shift ends, you should wear Health Eyewear that blocks all blue light, which generates an increased production of melatonin, so it will be easier to fall asleep - the glasses makes the body ready to sleep.

It can both save lives and large sums of money by implementing measures that take the human circadian rhythm into account. This is something that the community is already noticing as a major challenge in our increasingly widespread 24-hour society.
