Exposure to light has been found to have a significant impact on mental health, according to a recent study. The study, which is the largest ever conducted on the subject, revealed that individuals who were exposed to high levels of light at night had a 30% increased risk of developing depression and were more likely to experience psychosis, bipolar disorder, anxiety, PTSD, and self-harm. On the other hand, those who were exposed to higher levels of light during the day had a 20% lower risk of depression and were less likely to develop other psychiatric conditions.
One possible explanation for this link is that exposure to light at night can disrupt the body’s circadian rhythm or internal clock. To help realign circadian misalignment, experts recommend getting adequate light exposure throughout the day. This can be achieved by taking a short walk outside in the morning or at lunchtime, setting up a workspace near a window to attract natural light, and avoiding screens at night to decrease blue light exposure.
In cases where natural light is limited during fall and winter months, individuals can consider using a bright light box at home to get the necessary light exposure. By incorporating these strategies into daily routines, individuals may be able to improve their mental health by optimizing their exposure to light. Additionally, managing light exposure has also been found to be crucial in supporting mental well-being as research conducted in 2022 revealed that exposure to blue light led to reduced sleep duration in 33% of studies analyzed.
Overall, it’s clear that our relationship with light plays an important role in maintaining good mental health. By being mindful of our daily habits and making small changes like getting enough natural sunlight or using bright lights when necessary, we can take steps towards better mental well-being.
