The Impact of Age on Sleep
The age factor plays a significant role in the sleep cycle. As individuals grow older, not only does the overall length of the sleep cycle increase, but the specific stages and phases of the cycle are also affected. Particularly, the deep sleep periods known as N2 and N3 gradually decrease in duration, resulting in a reduction of regenerative hormone secretions during sleep for older adults. Furthermore, the time spent in non-rapid eye movement (NREM) stages decreases, making older adults more susceptible to being easily awakened. It is also more common for them to experience difficulties falling asleep and a decrease in sleep duration.
The Advantages of Napping
Napping is a practice that varies across different cultures. While some people prefer to sleep for a solid eight hours at night, others find value in taking short naps during the day. Interestingly, daytime napping can disrupt the body’s natural sleep-wake cycle, resulting in heightened alertness and productivity. However, it is important to note that extended naps or napping when experiencing insomnia can potentially disrupt nighttime sleep patterns.
