Using smart lights may improve susceptibility to depression
According to the BBC, we have to get up and go to work in the dark and come home from work in the dark down light led, which can have a negative effect on people.Many of us suffer from depression during the winter, leading to increased disease and reduced productivity.But can smart lighting improve our sleep and help improve our mood?
"I just thought that after the winter solstice, I started to breathe again," said Jacqueline Hazelton, a professor at the naval war college in Rhode Island.She says the winter solstice, usually on December 21, is the longest night of the year.After that day, the days began to lengthen."On a sunny day, I feel happier and more productive," says hazelton.And boring days can make my work less efficient.
Mind, a mental health charity, says most of us are affected by seasonal changes and the natural light we feel.Some of the effects are particularly severe, such as seasonal affective disorder (SAD), which is associated with depression at a particular time of year, affecting 9.5 percent in northern Finland and 9.9 percent in Alaska.But the researchers found that in sunny Florida, the figure was only 1.4%.
This winter, much of Europe is particularly dark.Moscow enjoyed only six minutes of sunlight in December, compared with 18 hours in previous years.
Professor hazelton's solution is to set the alarm for sunrise, which gently awakens her when the bright light gradually bathes the room."It made a difference," she said. "I didn't feel like I was being thrown out of the plane."
As time goes on, less sunlight can lead to lower levels of serotonin, a neurotransmitter that helps balance our emotions.When it gets dark, our bodies produce more melatonin and prepare us to sleep.The light of dawn will suppress melatonin and wake us up and make us energetic in the days ahead.This is the circadian rhythm, or our internal body clock.
That's why some experts believe that the depression light emitted by smartphones and laptops can interfere with our sleep patterns if we use too much before going to bed.On the other hand, the red end of the spectrum can help us relax.
