Light pollution is not just an issue for stargazers or the environment. It is a problem that affects all of us, including our health. Exposure to artificial light at night has been linked to various health problems, including disrupted circadian rhythms, insomnia, depression, and even an increased risk of certain cancers. Artificial light interferes with the production of melatonin. Melatonin is a hormone that regulates our sleep-wake cycle. This can result in sleep disturbances, fatigue, and decreased productivity. Light pollution also affects our mood and mental well-being, contributing to feelings of stress, anxiety, and depression. To minimize the impact of light pollution on our health, it's important to reduce exposure to artificial light at night and improve our sleep hygiene. This can include using dimmer switches, blackout curtains, and blue light filters, and avoiding screens for a few hours before bedtime.
