Do you find it difficult to leave the comfort and haven of your cosy, cocooning bed as autumn gives way to winter and the shortest, darkest days of the year?
Due to this shortage of daylight, our moods can drop, and we can feel low and lacking in energy; This is commonly known as SAD (Seasonal Affective Disorder). The exact cause of SAD isn’t fully understood, but given it’s seasonality, it is most probably linked to reduced exposure to sunlight during the shorter days of the year. It is extremely rare to find people with SAD living near the equator where daylight hours are long and bright all year round. In Northern Europe where there is a reduction in light in the winter it is estimated that one in ten people experience some symptoms of SAD such as depression and tiredness. Researchers also believe there may be genetic factors, as seasonal affective disorder has been observed to run in families
The mechanisms of SAD seem to be involved with sensitivity to reduction in light. When light hits the eye messages are passed to the hypothalamus (the part of the brain which controls sleep, appetite, mood and activity) to help you wake up and start your day. If there is not enough light these functions would slow down and gradually stop. Some people are a lot more sensitive to the reduction of light and much more likely to develop SAD. Two potential hormonal factors are a reduction in serotonin, which regulates our moods, and abnormally high production of Melatonin. Melatonin is the hormone which is produced in the pineal gland, as a response to a reduction in sun-light, and which helps us go to sleep. A rise in melatonin production is high in hibernating animals, which has helped develop an argument that SAD in humans could be a remnant of our ancestors need to ‘hibernate’ in the autumn in response to reduced food availability. In this sense a lower emotional mood could have led to reduced activity and a reduced need for calories.
SAD can often be treated successfully by light therapy. This involves sitting in front of or beneath a light box that produces a very bright light. Light boxes come in a variety of designs, including desk lamps and wall-mounted fixtures. It’s important to speak to your GP and read the manufacturer’s instructions before using a light box to treat SAD. Light boxes are at least ten times the intensity of household lights, and come in a variety of strengths and sizes – for SAD, a strength of at least 2,500 lux tends to be recommended. Sufferers use light boxes in different ways. Many people use them once a day, with the average time spent in front of the box is one or two hours a day during darker months and the maximum is about four hours. Some light boxes are much brighter and can cut treatment time down to half an hour. You can use your lights at any time of day, although it’s best not to use it before you go to bed, as the effect of the light may make it hard to sleep.

It’s important not to forget the huge role of exercise in the fight against depression. There is evidence that combining exercise and light therapy is a particularly good form of self help for SAD. Talking therapies including counselling, psychotherapy or cognitive behaviour therapy (CBT), can also be useful in helping one to cope with SAD symptoms. Anti-depressants are also used by the GP to treat SAD. Generally, the ones that tend to be used are those which influence Serotonin. Apart from being a major neurotransmitter, concentrations of serotonin drop to their lowest levels during the winter and rise to their highest levels in summer and fall. Silentnight’s resident sleep expert, Dr Nerina Ramlakhan, comments; “Winter has a significant impact on our sleep patterns. The season brings with it a dramatic reduction in light which causes a depletion in Vitamin D levels, which can effect both our energy levels and mood. During winter our bodies also produce too much of the hormone, melatonin, which can make us sleepy and groggy.” Using the combined expert knowledge of Warren Evans resident sleep adviser Dave Gibson and Silent Night’s Dr Nerina, we have complied a list of top tips to breeze through winter this year.
