The light room
Are you getting enough daylight? In the light room at Studenthälsan, you can compensate for some of your light deficiency. The room has light-coloured walls, floors, ceilings and furniture and the light has a high colour temperature. The brightness corresponds more or less to a cloudy summer’s day.
Do you get lethargic and tired in the autumn and winter? We often suffer from winter fatigue in the northern hemisphere. The change between light and darkness is an important signal when the body sets its circadian rhythm, which in turn is connected to important biological processes such as rest, activity, sleep and wakefulness. Somewhat simplified, when the days get shorter our bodies want more sleep.
The effect of artificial light is not scientifically proved, but many feel relaxed and refreshed in the bright environment. More regular visitors can experience better sleep, improved mood and more energy, as well as becoming more sociable and active. And the reading light is fantastic, so why not take the opportunity to use the time in the light room to study or immerse yourself in a good book.
The light used in the light room comes from fluorescent lamps with a high colour temperature and good spectral distribution (so-called daylight fluorescent lights or full spectrum fluorescent lights). The brightness in a light room is usually around 2,500 lux, which is about 10 times more than the light in an office. Put more poetically, it’s like a Swedish summer’s day, i.e. partly cloudy. The light affects the circadian rhythm which is coupled with important biological processes such as rest, activity, sleep and wakefulness. The idea is to compensate for insufficient light during the day. The light affects the secretion of melatonin and many feel more energetic after a few visits. The light room should not be considered a form of therapy – the experience is subjective and it’s up to you to decide if it makes you feel good.

Questions and answers about the light room
How bright is the light?
It is between 2,500 and 4,000 lux, which is like a slightly cloudy summer's day. When the sun shines it is at least 75,000 lux. During winter, the brightness of the light is often under 800 lux.
Will I become tanned?
No. The light does not contain any UV light.
Do I need sunglasses?
No. The point of the light room is that you will be exposed to the light. Sunglasses or closing your eyes lessens the effect the light room has. The light room is designed in such a way that you will be exposed to enough light without becoming blinded.
How often should I go?
Light affects people in different ways. You determine yourself how often you should go. Many go once a week whilst others need more light and go every day during a two week period.
What time of the day is best to go?
Day time is best, the time when it is usually light outside.
What should I do in the light room?
Study, read, talk to light buddies. Light that falls in the periphery of your vision is meant to be very beneficial.
