Why do we need more light in our lives?

Whether you live in an area where daylight is short or short, your exposure to the sun affects you, depending on your location on the planet.

If you live in the northern hemisphere, the night gets shorter as the day comes up, and vice versa if you live south of the equator.

Most months of the year are rich in delicacies, such as heating fires, cozy blankets and oily meals, but exposure to the sun is important to our health.

Most of us recognize the feeling of more activity and happiness at the end of the winter, or sadness and weakness as we separate from the summer.

There are scientific explanations for all this because exposure to light affects our bones and our brains.

Here are the reasons …

1. Light controls our biological clock

Our bodies organize 24-hour sessions. It reflects the time it takes the Earth to rotate around its axis.

It is known as the biological clock, which affects the whole body, from sleep to metabolism, through metabolism, as well as the release of our body by certain hormones.

The rhythm of the biological clock continues in the absence of outside influences. Scientists remained in a cave without any source of natural light nor division in time found that the rhythm of their biological clocks continued to follow cycles of about 24 hours each. But our body reacts so strongly to the light.

Daylight helps stimulate a wide range of biological functions in the body.

2. Light helps us sleep and wake up

Sleep is one of the many biological functions that daylight helps to stimulate. Light makes our brain aware that vigilant systems are now under control.

On the other hand, when it's dark, the body begins to secrete melatonin, the chemical that helps us sleep.

Some airlines are currently lighting aircraft cabins to help overcome the insomnia caused by travel between different time zones. For example, bright lights are used to board pbadengers, soft lighting during dinner and sunset lighting to help pbadengers sleep.

3. light MayTreatment L & # 39; insomnia

We now know that some kind of light from the computers, tablets and phones we use can prevent the release of hormones necessary for our sleep.

The new guidelines issued by most health authorities indicate that it is necessary to move away from these devices for some time before going to bed, leaving them outside the room.

This is consistent with neuroscientist and sleep researcher Matthew Walker, who believes that "daylight is the key to organizing everyday sleep patterns."

If you have trouble sleeping, an hour of morning sun exposure helps to stimulate the mind and body at the right time, which will help you feel sleepy at bedtime.

4. The light affects our mood

The daily dose of daylight is not only important for our sleep habits, but it also stimulates brain changes that make us happier.

When the body recognizes sunlight, which reaches the brain through the optic nerve, serotonin levels, which are responsible for the feeling of comfort, increase.

On the other hand, those who are less exposed to the sun, such as seizures, may suffer from depression.

There is a mental health problem directly related to the fall of the day in autumn and winter, called "seasonal affective disorder".

People with seasonal affective disorder show symptoms of depression appearing at shorter times of the day. This feeling is sadly falling as spring approaches.

The current hypothesis suggests that seasonal affective disorder is one of the effects of our disruption of the biological clock, which is directly caused by the decrease in the brightness of the sun.

If you suffer from a seasonal emotional disorder, consider buying a special lighting device that simulates daylight. Exposure to the light of the device for half an hour in the morning can help change the pace of the body clock and improve your mood.

5. sunlight Maintains hardness Bones

We need vitamin D so that our body absorbs calcium and phosphates from our foods, minerals that are very important for healthy bones, teeth and muscles.

Vitamin D deficiency, on the other hand, causes bone weakness and weakness as well as skeletal abnormalities.

Fortunately, we can get the vitamin D we need from the sun, which is why we also call it "vitamin sunlight".

Our body creates vitamin D when our skin is directly exposed to the sun. Most of us can thus get the vitamin D needed by the body.

However, exposure to the sun can be very dangerous. So be sure to use protective lotions while avoiding direct sunlight during the hottest days of the day.
