The brain boosts if it happens in a bright time rather than a dark morning in winter

bySarah Horrigan

Because sunrise will be delayed in winter, many people get up and go to work in the dark in the morning and commute. However, from a biological point of view, the late morning · the brain got boosted at the bright time, the kickstart of the day got out and the brain's function would fall through the day as it happens in the dark time, the Westminster University ofAngela ClowMr. Explains that mechanism.

In the UKGreenwich Mean Time(GMT), But from 1 o'clock last Sunday of March to 1 o'clock last Sunday of OctoberBritish daylight saving time(BST), And the time taken by one hour from GMT is standard time. In other words, it will return to 1 o'clock of GMT on the last Sunday of the last Sunday in October, so the actual time will not change, but one day will become one hour earlier in a sensuous way, greet a brighter evening It will become available.

But Angela Clow of Westminster University says that it is biologically more important to have a more "bright morning" than to have a brighter evening.

The intensity of light is detected in specific cells in the retina and integrates the whole body clock with the hypothalamusSuprachiasmatic nucleusIt will be passed on to you. At this time, since the hypothalamus is the part that controls the endocrine system, the light entered from the eye is greatly related to hormone secretion in the body. Known as "stress hormone"CortisolEven one that is affected by light. Cortisol has a big influence on the brain and body, and it creates a pattern of 24 hours a day, which is the basis for us to live a healthy life.

The fact that cortisol is explosively secreted in the first 30 minutes after getting up is called "Cortisol reaction at the time of waking (CAR)", the larger the amount of light when rising in the morning, the larger the CAR, It is said that the work of the brain of the day will improve better. Then,In previous studies, People waking up in the darkest time of winter have been adversely affected by the seasonal change and it turned out that the CAR level was low. In other words, in fall and winterSeasonal affective disorderPeople who become stressed or worried by stress and anxiety may have low CAR but it is also possible to return the state of CAR to original using artificial light(PDF file)Is shown.

Especially in the morning to cure the dark mood in winter that it is effective to take lightWhere we found out in previous studies. further,According to research in 2014, CAR is related to plasticity and function of the brain and works to raise the ability of executing functions such as target setting, decision making, and planning. The opposite thing can be said, it is reported that the execution function decreases as CAR decreases with age.

As you can see from the above, awakening in the morning is biologically very important, whether or not the kickstart of the day is over depends on whether Cortisol boosts or not. As cortisol receptors are present in the body, fully secreted cortisol is received by their receptors, from which chain reaction occurs, our body is ready to tackle the problem of the day That's it.

Since you can not boost Cortisol in the dark morning, you can reduce the biological chain reaction and you will not be able to work the body well enough compared to the day when you took light well. From a biological point of view, it can be said that the way the brain and the body work are better if it happens in the late time when the sun rises firmly and the light overflows, rather than happens in the dark time in the winter morning without sunrise.
