Why You Shouldn’t Leave The Lights On Before Going To Bed At Night.

How many times have you fallen asleep with the lights on or even stayed up late to use a computer right before going to bed? Almost every single time, right?

Note that a key factor in maintaining your sleep is exposure to light or to darkness so falling asleep with the lights on, may not be the best thing to achieve a good night’s sleep.

Falling asleep with the lights on may forestall the apparition, but research proposes that over time, too much light could interfere with healthy sleep disorders and other health problems.

According to emerging research, sleep disorders and nighttime lighting may be making us fatter, more depressed and more likely to develop cancer.

One study on women found that obesity was more prevalent in those who slept with a television or lights on. A factor in lack of sleep-induced obesity could be food intake. Studies have shown that the less sleep you get, the more food you will likely eat the next day.

Also, if light continue to interfere in your sleep over a long period of time, you could be at an increased risk of certain chronic illness whether you are obese or not. These include not only cancer as aforementioned, but high blood pressure, heart diseases and type 2 diabetes.

It isn’t surprising however, that many people do find themselves falling asleep to the glow of a television or a computer screen.

Moreover, says Insomnia researcher, PhD holder and associate professor of psychology at Ryerson University in Toronto, her patients’ disinclination to turn off these light sources in order to get a better night’s sleep gave her an idea that research confirmed afterwards: The need for a TV, a spouse or a light source to feel cosy falling asleep, may be embedded in a fear of dark.

For most of history, humans did not need to seek out darkness. The looming of electricity in the 20th century fundamentally changed our relationship to light and dark, and posed serious new challenges to sleep. Artificial light wreaks frequent havoc on sleep without many people even being aware of its detrimental effects. The widespread use of digital technology-and the light emitted from all these screens-has introduced another highly disruptive challenge.

A sleep routine that involves a gradually obscure environment can help. The body needs time to rest, so, dim the lights a full hour before bed time to encourage your body to begin its physiological continuance toward sleep.

Using a dimmer switch on overhead lights and installing low-watt helps to control their brightness.

If you need a source of light in the night to make your way any where, use a night light with a red bulb. Red is a long wavelength light that has been shown less distracting to sleep than other lights wavelength.
