Light therapy is a treatment that involves exposure to artificial light that mimics natural sunlight. It is often used to help regulate sleep patterns and improve sleep quality by influencing the body's circadian rhythm. By using light therapy, individuals can adjust their internal clocks, making it easier to fall asleep and wake up at desired times. This therapy is particularly beneficial for those suffering from sleep disorders such as insomnia or delayed sleep phase syndrome, as it helps to reset the body's natural sleep-wake cycle, leading to better overall sleep.
