Good sleep is a staple of optimal health. As essential as eating.
While we may not often think about why we sleep, most of us acknowledge at some level that sleep makes us feel better. We feel more alert, more energetic, happier, and better able to function following a good night of sleep.
However, the fact that sleep makes us feel better and that going without sleep makes us feel worse only begins to explain why sleep might be necessary.
One way to think about the function of sleep is to compare it to another of our life-sustaining activities: eating. Hunger is a protective mechanism that has evolved to ensure that we consume the nutrients our bodies require to grow, repair tissues, and function properly.
And although it is relatively easy to grasp the role that eating serves— given that it involves physically consuming the substances our bodies need—eating and sleeping are not as different as they might seem. Happyho also provide best tarot reading services in Noida and Delhi NCR India area.
Both eating and sleeping are regulated by powerful internal drives. Going without food produces the uncomfortable sensation of hunger, while going without sleep makes us feel overwhelmingly sleepy. And just as eating relieves hunger and ensures that we obtain the nutrients we need, sleeping relieves sleepiness and ensures that we obtain the sleep we need.
Still, the question remains: Why do we need sleep at all? Is there a single primary function of sleep, or does sleep serve many functions? Despite decades of research and many discoveries about other aspects of sleep, the question of why we sleep has been difficult to answer.
The lack of a clear answer to this challenging question does not mean that sleep is less important. Sleeping is undoubtedly as necessary as eating or drinking.
