What is the cause of lack of sleep at night?
Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep. Stressful life events or trauma — such as the death or illness of a loved one, divorce, or a job loss — also may lead to insomnia. While insomnia can be a symptom of psychiatric disorders, like anxiety and depression, it is now recognized that sleep problems can also contribute to the onset and worsening of different mental health problems, including depression, anxiety, and even suicidal ideation. Most people can recover from sleep deprivation with only a few — or even just one — nights where they get enough quality sleep. However, some people may need several nights of quality sleep to recover from long-term sleep deprivation. In fact, inadequate sleep duration has been linked to 7 out of 15 leading causes of death in America—including cardiovascular disease, cancerous tumors, cerebrovascular disease, accidents, diabetes, septicemia, and high blood pressure. The cumulative long-term effects of sleep loss and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke. In particular, vitamins B6, B12, C, D, and E can improve or lower your sleep quality and duration. Vitamin C deficiency and both lack and an excess of vitamin B6 in the body might affect your sleep or cause insomnia.

Specifically, vitamin D deficiency (VDD) can increase risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings in children and adults [13,14,15]. For most people, 4 hours of sleep per night isn’t enough to wake up feeling rested and mentally alert, no matter how well they sleep. There’s a common myth that you can adapt to chronically restricted sleep, but there’s no evidence that the body functionally adapts to sleep deprivation. Successive multi-organ injuries scar organs and induce fibrosis, which causes myocardial infarction, diabetes mellitus, and liver and kidney dysfunction. This might explain these chronic diseases in humans who undergo long-term successive sleep deprivation. Melatonin, released by the pineal gland , controls your sleep patterns. Levels increase at night time, making you feel sleepy. While you’re sleeping, your pituitary gland releases growth hormone, which helps your body to grow and repair itself.
How lack of sleep affects the brain?
Scientists are suggesting that extended wakefulness may be linked to permanent loss of locus coeruleus neurons, cells that are essential for optimal cognition and alertness. According to CNN, even trying to make up for lost sleep by cramming in extra hours the next day doesn’t help the brain recover. Reasons this might happen include drinking caffeine or alcohol late in the day, a poor sleep environment, a sleep disorder, or another health condition. When you can’t get back to sleep quickly, you won’t get enough quality sleep to keep you refreshed and healthy. This is because our brain is constantly forming new connections while we are awake. The longer we are awake, the more active our minds become. Scientists believe that this is partly why sleep deprivation has been shown to reduce symptoms of depression. However, there are negative outcomes of this, too. An ongoing lack of sleep has been closely associated with hypertension, heart attacks and strokes, obesity, diabetes, depression and anxiety, decreased brain function, memory loss, weakened immune system, lower fertility rates and psychiatric disorders. Overall, it’s best to go to bed earlier in the night and wake up early each day. Still, this type of sleep schedule may not work for everyone. It’s far more important to make sure you get enough sleep and that it’s good quality sleep. You can ensure this happens by going to bed and waking up at the same time every day.
