Shine some light on the long, dark nights with our pick of the best health-boosting lighting

Whether it’s your mood, energy or sleep that could do with a boost, a little light therapy might be able to help. “When the days are short and dark, our bodies can go into hibernation mode - closing down in a variety of ways to preserve calories at a time when, historically, there was less food around,” explains Dr Norman E Rosenthal, author of Winter Blues and the man who first coined Seasonal Affective Disorder (SAD). “A more extreme SAD sufferer may experience depression, sadness and despair but in milder cases you may just find it a little harder to concentrate, have more difficulty waking up or suffer from lower energy or libido,” he says.

“Research has shown that light therapy can help SAD sufferers by boosting the levels of the hormone serotonin in the brain,” explains Dr Rosenthal.

But what makes the best light therapy?

“For the full medical treatment, the light should have a ‘lux’ of 10,000,” says SAD sufferer and spokesperson for charity SAD.org.uk Jenny Scott-Thompson. “Milder winter blues might benefit from less though and products like sunrise alarm clocks and daylight bulbs can be helpful either in addition to lightbox treatment or alone.”

The bigger the surface area of the light source, the better. Dr Rosenthal suggests a lightbox of at least a foot square although Scott-Thompson acknowledges the need to balance size against your space and lifestyle. “Most providers offer a free trial,” she says. “You should be able to tell after a week if a product is helpful.”

“For best results, use a lightbox as early in the morning as possible,” says Scott-Thompson, “If you use them later in the day, try to avoid evening when they might impact on your sleep.”
