Avoid artificial light?
That’s right. Recent research is revealing that artificial light can affect our body clock. Having your lights on late at night, staring at a computer screen, even a TV or smartphone, can suppress your body’s melatonin secretion (that’s what makes you feel sleepy each night) and thus disrupt your natural wakeful/ sleepy rhythm.
Even worse, researchers have found that the suppression of melatonin may be linked to serious illnesses, such as cancer, heart disease and diabetes.
Blue light
Blue light (wavelength about 475 nanometres) seems to be the worst culprit & modern lighting in the form of low-energy fluorescent bulbs & LED-based lighting has more blue light than the old tungsten light bulbs. American researchers George Brainard, Charles Czeisler & Steven Lockley have found that blue light resets people’s internal clock by 3 hours on average, compared with just one and a half hours for green light. Resetting internal clocks in this way means people find it harder to get to sleep the following night and consequently feel tired in the morning.
Dim your lights, feel sleepy & get a full night’s sleep on your memory foam mattress
Along with a good-quality memory foam mattress, routinely dimming your lights well before your bedtime, avoiding TVs, computers & smartphones will help you achieve a restful night’s sleep. Cheap quality memory foam mattresses are now readily available online and it won’t cost you anything to dim your lights in the evening.
NASA considers these findings about the effect of artificial light on melatonin secretion so important that it recently reduced the upper limit of illumination in the general sleeping areas of spacecraft, where some astronauts might be active alongside their sleeping workmates, and reduced the lighting even more so in areas solely for sleeping, respectively equal to full moonlight and a quarter moon brightness. It was NASA’s earlier concern for the safety and comfort of its pilots back in the 1960s that brought about the creation of early memory foam material, that important constituent of memory foam mattresses.
A study this year found that melatonin levels in people exposed to normal room lighting in the late evening rose later than in people subjected to dim lighting and then remained high for about 90 minutes less (Journal of Clinical Endocrinology, Vol.96, p.463, 2011). But it seems that even relatively dim lights, such as computer screens and table lamps, can affect our sleeping rhythm, making us fall asleep later than we would in more natural circumstances. Steven Lockley and his colleagues suggest that perhaps this may explain the high occurrence of delayed sleep phase disorder, in which people experience trouble getting to sleep and wake up feeling tired.
A blue light during the day & a memory foam mattress overnight will help keep you alert
Remember that bright blue lights are a good choice for keeping people alert and cheerful by day, especially in the darker days of winter. Choosing a good quality memory foam mattress will give you a restful night’s sleep and thus help keep you alert and cheerful by day.
Whether people can wean themselves off their addiction to computers, TVs and smart screens in the evening is debatable, but the provision of light bulbs in the evening which use less blue light would be a good idea; already, one recently launched low-energy lighting called ESL ( Electron Stimulated Luminescence ) has a spectrum more like that of incandescent bulbs.
Try to keep your body clock ticking at the right time, feel sleepy at the right time and enjoy a full quality night’s sleep on your memory foam mattress.
