How Light affects Metabolism and Sugar Levels

0

Most of us are aware of the importance of sunlight on the production of vitamin D. Some have also heard that light from electronic devices can worsen sleep.

But few people know that light affects the metabolism in the body.

Light and level of sugar

In a recent study conducted by the Northwestern University, a bright blue light was sent to people for three hours 2 times a day.

The researchers found that bright light, both in the morning and in the evening, increases the resistance of cells to insulin. This can lead to weight gain and the development of diabetes.

The highest levels of sugar in the blood were observed when the bright light was exposed in the evening.

An earlier analysis also revealed that exposure to light after noon results in a higher accumulation of excess weight than before noon.

What does this mean?

These data confirm that the brightness of light, as well as the time of day in which we are exposed to it, directly affect health.

Of course, you need to consider all types of light, including electronic devices: smartphones and tablets, television monitors and laptops.

If you spend the whole evening among the glowing screens that knock down the internal clock, note that this is one of the possible reasons why it is so difficult to get rid of excess weight.

Evening is not for light

In the future, more likely, there will be new data on how you can use light to control metabolism.

While it can be confidently said that bright light in the morning is more useful for health than in the evenings.

This conclusion is another good reason not to use electronic devices in the evening hours and do something more enjoyable. For example, just relax.
