Lack of quality zzzs *actually* does make things feel funnier.
“It starts with the brain, specifically the prefrontal cortex,” he explains, adding that one of its primary functions is to regulate emotions and inhibitions—this is why babies and children are so easily amused. “In many ways, the prefrontal cortex works like the brake pedal for your emotions,” Dr. Shumway says. “Your nervous system is constantly reacting to the environment, and your prefrontal cortex has to decide whether to let the feelings out or not.
“Sleep deprivation is incredibly dangerous, both in the short and long term,” Dr. Shumway says. “People who are sleep deprived are less rational, perform worse on motor tasks, and cannot record memories properly.” He adds that things are even worse for those who suffer from chronic sleep deprivation. “They can experience a reduced immune system response, increased blood pressure and cardiovascular disease, decreased working memory and reaction times,” he says.
But that isn’t the case if sleep deprivation is happening on the regular. If that’s the case, it’s time to start looking at lifestyle causes that could be contributing to your lack of quality zzzs. “Stimulants, such as caffeine, can reduce the experience of tiredness; however, they tend to mask the underlying symptoms of exhaustion rather than act as a cure,” Dr. Shumway warns.
Rather, he suggests speaking to a professional to get to the root cause. “If you struggle with chronic sleep deprivation or insomnia, consider working with a therapist that specializes in[cognitive behavioral therapy for insomnia] a specialized form of talk therapy designed to treat difficulties with sleep,” Dr. Shumway suggests.
