The harmful effects of light are discussed below:
To discuss about light and its harmful effects, first it is necessary to have some idea about what is light, its types and its effect on our daily life. light is an essential part of our lives, but it also has some harmful effects. ultraviolet (uv) rays can cause skin and eye damage, such as skin cancer and macular degeneration. prolonged exposure to digital screen light puts strain on our eyes, which can cause digital eye strain. in addition, excessive lighting at night reduces sleep quality, which adversely affects physical and mental health. so it is important to be careful in using light.
Light and its types:
1. Natural light:
Natural light is the flow of light from the sun that illuminates our lives. it is essential for plants and animals, as it helps in the process of photosynthesis. various properties of natural light such as heat, brightness and color intensity have important effects on our daily life. the prothom-alo of the sun in the morning lifts our spirits, and the setting sun in the evening brings a sense of calm. using natural light can reduce electricity consumption and is also beneficial for our health, as it helps in the production of vitamin d.
2 .Artificial light: Nowadays we depend a lot on artificial light. although artificial light has improved many aspects of our lives,
artificial light is man-made light that replaces natural sunlight. it is generated from various sources, such as bulbs, leds, fluorescent lamps, etc. the main purpose of artificial lighting is to increase visibility in dark environments. it is important for residential, commercial and industrial installations. workplaces, roads, parks etc. are illuminated by artificial light. artificial lights of different colors and intensities are used. artificial lighting has become more advanced and effective with modern technology, such as smart lighting systems that can automatically adjust according to the environment. however, it can have some harmful effects.
Harmful effects:
1. Insomnia: One of the main problems with artificial light is that it disrupts the human sleep cycle. in particular, the light from smartphone, computer and tv screens at night can cause insomnia. this reduces the production of melatonin, which is essential for sleep.
2. Vision problems: Prolonged work in artificial light or screen time can damage vision. it can cause eyestrain, headaches and problems with focus.
3. Effects on mental health: Both lack of light and excess light can have negative effects on mental health. changes in lighting can cause depression and anxiety issues. in particular, seasonal affective disorder (sad) can be caused by reduced exposure to sunlight during the winter.
4. Skin problems: UV rays can cause various skin problems, such as aging, skin cancer, and other skin problems. using artificial uv light (eg sun beds) can damage skin health.
5. Physical health: Studies have shown that working in excessive night light or lack of sleep also affects physical health. it can increase the risk of obesity, diabetes and heart disease.
Lighting management and remedies:
Some effective steps can be taken to reduce the harmful effects of light:
1. Limiting use of smartphones and computers: Use of screens should be reduced at night. if needed, blue light filters can be used.
2. Creating a sleeping environment: The room should be kept dark while sleeping and the use of artificial light should be reduced.
3. Exposure to natural light: If possible, try to be in natural light as much as possible during the day.
4. Take a break: If you work together for a long time, you should take a break to rest your eyes.
5. Protection: Sunscreen is necessary to protect the skin from uv rays.
Conclusion:
Light is an essential part of our lives, but it has some harmful effects that can negatively affect our physical and mental health. with awareness and proper management we can reduce these effects and keep our lives healthy. therefore, it is our responsibility to be aware of the use of light and take necessary steps
