We get older as we continue to live. Age brings with it increased awareness of physiological and psychological issues. One of these issues is insufficient sleep. Many sleep disorders and dysfunctions that impair the sleep of elderly people were studied by sleep experts a few decades ago, and now there are numerous solutions for this problem. Where and how do we find sleep? There are several psychological processes that take place while we sleep. Brain waves (electroencephalography, or EEG), eye movements (electro-oculography, or EOG), and submental muscle tension can all be used to evaluate how well you're sleeping (electromyography or EMG). The information presented above is utilized in order to distinguish between the various stages of sleep. Technology advancements have lowered the cost of evaluating sleep disturbances, so one full night of sleep is no longer enough for an appropriate diagnosis of a sleep disorder. According to a study by researchers, 50% of people above the age of 65 have trouble sleeping or have sleep disturbances. Recent findings by sleep experts have shown that poor physical health or depression are frequently accompanied by sleep problems. Our sleep patterns vary as we age, and these age-related variations in sleep might be influenced by a variety of reasons. Several studies have looked into whether the desire for sleep decreases with age or whether the capacity to sleep declines with age.
