How Does the Lighting in the House Affect the Human Body?

Light is the source of life on earth. Vision is one of the most important sense organs, with which we receive up to 90% of information about the world around us. The eyes need light to see. When there is not enough natural light, artificial lamps come to the rescue, which also affect our body.

The importance of light for health

Of course, natural light is the most favorable for a person. But in our northern latitudes, especially in winter, it is not enough. That is why in winter the body is more susceptible to diseases and stress. But since we cannot, like many animals, fall into suspended animation for the whole winter, we need to continue to live and work, artificial lighting begins to play a major role in our lives. Therefore, it is important that the lighting does not fail. If this happens, and you cannot cope with the problem on your own, then you need to contact an Electrician Ottawa who will professionally solve your problem.

How does it affect health?

The human body has a biological clock, the so-called circadian cycles, which are responsible for the production of sleep and wakefulness hormones. With a lack of light, the level of melatonin, the sleep hormone, increases, a person experiences fatigue and drowsiness. Lethargy and apathy most often accompany us in the autumn-winter period, when the sunny day is short. Artificial light allows you to extend it. Having “deceived” the biological clock in this way, we get the opportunity to work productively when it is already dark outside the window.

Lighting affects:

  • Vision – the twilight makes you strain your eyesight, the eye muscles get tired quickly, and this affects the general well–being – headaches occur, we feel tired.
  • Metabolism – according to internal biorhythms, it slows down with insufficient light.
  • Growth and development – everything grows in the light.
  • Heart function and blood circulation.
  • Immunity and the ability of the body to resist negative influences.

Negative consequences of incorrect lighting

Proper artificial lighting helps us stay active throughout the day. But the wrong thing can cause huge harm:

  • The retina of the eye – too bright and incorrectly directed light can lead to biochemical changes.
  • The nervous system – the excess of light and flickering produced by some lamps irritates and interferes with concentration.
  • As a result, the level of melatonin production decreases, insomnia and related ailments appear.

Artificial lighting becomes our friend only if it is organized correctly.

The effect of light on mood

The lack of light is very dangerous, a person may feel depressed in a poorly lit room, it is difficult and uncomfortable to be there. Bright light affects:

  • Stimulates the brain, gives energy – great for creating a working environment in the office and workshop.
  • Comfortable, sufficient light gives cheerfulness, we feel a surge of strength, the mood is positive.
  • Too bright light is a source of anxiety and irritability.
  • Soft light disposes to relaxation and peace, it is good for relaxation, for the bedroom, but it is not suitable for work.

And so, our health and mood depend on the illumination.
