Is your BEDROOM making you fat? Bright lights and streetlamps 'could be causing weight gain'

By Fiona Macrae

Do you spend all day eating salad and carry out lots of exercise, but never seem to get any thinner?

Your bedtime habits could be to blame, as new research shows too much light in the bedroom may make us pile on weight.

Scientists believe that light at night, including street light creeping through the curtains and the glow of smartphones, is causing us to pile on the pounds.

In experiments on mice, they showed that animals exposed to light 24-hours a day for five weeks put on 50 per cent more fat than creatures who kept more normal hours.

This was despite all the animals eating the same amount of food and doing the same amount of exercise.

Tests showed that constant light disrupted their body clock and slowed down a vital calorie-burning process.

Note that the experiment involved exposing the mice to the same levels of light all day long. Light "leaking around a curtain" probably won't make much difference unless you are a light sleeper.

Make this Common Mistake While Sleeping and Risk Gaining Weight

October 28, 2010

Keeping a light on at night could change your eating schedule, and the result could be extra pounds. Mice exposed to a dim light at night gained 50 percent more weight over an eight-week period than mice that slept in total darkness.

The findings held up even when the amount of food and the physical activity of the mice were held constant, and the results could apply to people who eat meals late at night.

The researchers suggested that modern society's 24-hour-a-day schedule may be having an impact on metabolic function and weight gain.

Live Science reports:

"... [P]revious work has shown hormones that aid in metabolism are affected in humans exposed to light at night ... Night light could have reduced those hormones in mice, and coupled with a disruption in the mice's internal clocks, could have been responsible for their weight gain."

You may think nothing of turning on your bathroom light in the middle of the night or sleeping next to the glow of your clock radio. But powerful research is emerging that shows exposure to light during the night can seriously impact your body's internal clock, leading to metabolic changes and weight gain.

In fact, mice that were exposed to dim light during the night gained 50 percent more weight over an eight-week period than mice kept in complete darkness at night. They also had increased levels of glucose intolerance, a marker for pre-diabetes.

The weight gain occurred even though the mice were fed the same amount of food and had similar activity levels, and the researchers believe the findings may hold true for humans as well.

How Does Light Impact Your Weight?

When mice were exposed to night light, they ended up eating more of their food when they would normally be sleeping and this lead to significant weight gain. However, in a second experiment when researchers restricted meals to times of day when the mice would normally eat, they did not gain weight, even when exposed to light at night.

This suggests that the timing of your meals, for instance eating late at night when you'd normally be sleeping, may throw off your body's internal clock and lead to weight gain. In this case, the artificial light, such as a glow from your TV or computer, can serve as the imputes for keeping you awake and, possibly, eating, when you should really be asleep.

In other words, while it's typically thought that your biological clock is what tells you when it's time to wake up or go to sleep, light and dark signals actually control your biological clock. In turn, your biological clock regulates your metabolism.

So when your light and dark signals become disrupted it not only changes the times you may normally eat, it also throws your metabolism off kilter, likely leading to weight gain.

*wonders which is more dangerous.. night light or falling down on the way to the bathroom in the dark* Not having a night-light is FAR more dangerous. When you fall down on the way to the bathroom in the dark (because you didn't have a night-light), then you'll be even more defenseless when the boogey-man jumps out to get you (because you didn't have a night-light ...)

Basically, anything EXCEPT your daily food intake is making you fat.

There ya have it. Drink wine and turn off the lights if you don't want to be fat.


Wine bedtime snack can help you lose weight, study claims

Wine drinkers rejoice. A new study has found that a glass of wine before bed can help you lose weight.

According to The Daily Mail, Harvard University studied 20,000 women over 14 years. :confused: They drank a half a bottle of wine a day. Researchers found the women who drank had a 70 percent reduced risk of obesity compared to non-drinkers.

The National Institute for Alcohol Abuse and Alcoholism also agreed, saying "when alcohol is substituted for carbohydrates, calorie for calorie, subjects tend to lose weight, indicating that they derive less energy from alcohol than food," The Daily Mail reported.

Another study said a glass of red wine every night increased the good cholesterol HDL.
