Vitamin deficiencies linked to insomnia and poor sleep

Many people around the world struggle with insomnia, a condition that affects sleep. Recent health discussions highlight the role of vitamin deficiencies in sleep problems. Experts say that lacking vitamins B12 and D can lead to sleeplessness. People who do not get enough vitamin C may wake up feeling tired, no matter how long they sleep. Research shows a connection between vitamins and sleep quality. Low vitamin D can cause poor sleep and shorter sleep durations. This vitamin is found throughout the brain, particularly in areas that help regulate sleep. Similarly, a lack of vitamin C is linked to less sleep. Studies indicate that those who sleep well tend to have higher vitamin C levels. Vitamin B12 is crucial for sleep as well. Low levels of this vitamin can lead to longer sleep durations and a higher risk of insomnia. It affects the body's natural sleep-wake cycle. Insomnia can result from various factors, including stress, poor sleep habits, and health issues like depression or ADHD. Lifestyle choices, such as late-night gaming or consuming caffeine, can also disrupt sleep. Experts estimate that insomnia affects about 10–30% of the global population. They recommend discussing dietary changes or vitamin supplements with a doctor. Other solutions include cognitive behavioral therapy and certain medications.
