細胞修復是如何進行的？
我們的身體每日都會為我們進行各式各樣的工作。由睡眠週期最深層的階段睡醒的一刻開始，我們的細胞就無間斷地管理著體內的損耗。細胞修復在維持健康中扮演最基本的角色。不論任何環境，地球上的生命都呈現同樣的過程：每日重新開始，消耗能量，然後休息，以求在下一天恢復過來。沒有細胞修復，就不可能實現這個萬物通用的過程。
甚麼是細胞損傷
我們曾幾何時都見過細胞的圖像：透薄的圓球體，具有各種色彩、形狀、結構和大小。有些細胞呈黏軟狀和脆弱。我們的細胞每日都暴露於環境毒素、有害的化合物，和試圖傷害它們的致病原中。
這些環境因素和致病原嘗試攻擊我們的DNA。每當DNA受襲，細胞必需尋找方法修復這些損傷。 細胞損傷導致細胞週期驟停，複製和分裂停頓，細胞必需找出修復損傷的辦法，讓細胞週期得以恢復。
是甚麼觸發體內的細胞修復？
一種稱為NAD+的輔酶在啟動細胞修復過程上起著重要的作用。
NAD+是一顆充當著助手的分子，幫助產生細胞能量和激活Sirtuins，從而全方位調節細胞健康。
然而，許多因素會導致NAD+水平隨時間下降。破壞NAD+的壓力來源和代謝性的侵害有以下例子：
- 靜態生活方式
- 飲酒
- 暴飲暴食和營養不良
- 睡眠不足
- 日照
有了足夠的細胞能量，細胞就會透過重建任何受損或失去的結構而得以恢復。大多數細胞修復都是以這種方式進行，各個部件協同工作，執行這個過程中不同的階段，直到細胞回復至其原來的結構。
並非所有的細胞或細胞單元都以相同的方式再生。在《科學》期刊發表的一項研究中，科學家證明了在多細胞的情況下，某些細胞可以生產全新的細胞，來取代失去了的細胞。但是在單細胞的層面上，再生重建則成為一個較複雜的過程。 在這種情況下，當損壞穩定下來後，細胞通常會重建並更換缺少了的組件。在單細胞層面，恢復結構和功能需要更長時間、更多能量和步驟。在某些情況下，細胞結構將會永久改變。
維持NAD+水平以支持細胞修復
保持健康的NAD+水平，有助細胞準備就緒，以協助進行各種修復工作。從基本的自噬作用，到糾正各種形式隨衰老而來的細胞損傷，高水平的NAD+可以全面支撐細胞的復元能力。
總而言之，獨特的修復能力使我們的細胞成為生物界的超級巨星，而提升NAD+的補充劑可有助支持它們的功能。無論您採用哪種養生的方式，都要照顧好您的細胞。它們不斷工作，使我們得以保持健康、活力和韌性。

How Does Cellular Repair Work?
Every day, our bodies carry out all manner of tasks for us. From the moment we wake through the deepest phase of our sleep cycle, our cells continually manage the internal wear and tear of life. Cellular repair plays a fundamental role in maintaining our health. Regardless of environmental circumstances, life on earth unfolds the same way for us all: we start anew each day, expend energy, then rest in order to recoup for the day to come. Without cellular repair, this universal process would be impossible.
What is cell damage?
At some point in time, we’ve all seen images of cells: ethereal, rounded orbs that come in a variety of colors, shapes, textures, and sizes. Some cells are squishy and fragile. Every day, our cells are exposed to environmental toxins, hazardous compounds, and pathogens that are attempting to damage them.
These environmental factors and pathogens attempt to attack our DNA. Every time DNA is assaulted, our cells must figure out how to repair the damage. Cell damage causes cell cycle arrest, where duplication and division are placed on hold and cells must find a way to repair any damage before the cell cycle can resume.
What sparks cellular repair within the body?
A vital coenzyme called NAD+ plays an important role in getting cellular repair processes started.
NAD+ is a “helper molecule” that assists in generating cellular energy and activating sirtuins, which regulate our cellular health across the board.
Unfortunately, many factors contribute to lower NAD+ levels over time. Examples of NAD+ damaging stressors and metabolic insults include:
- Sedentary lifestyle
- Alcohol consumption
- Overeating and poor nutrition
- Sleep deprivation
- Sun exposure
With enough cellular energy, your cells regenerate by re-creating any structures that were damaged or lost. Most cellular repair works this way, with various components working together to carry out different stages of the process until the cell is restored to its original structure.
Not all cells or cellular units operate in the same way when it comes to regeneration, either. In a study published in the Science journal, scientists demonstrated that in multi-cellular cases, some cells can generate entirely new cells to replace any lost ones. But at the single-cell level, regeneration becomes a more involved process.
In such cases, the cell usually rebuilds and replaces missing components after the damage has been stabilized. Restoring structure and functionality at the single-cell level requires more time, energy, and steps—and in some cases, the cellular structure becomes altered permanently.
Maintain NAD+ levels to support cellular repair.
Maintaining healthy NAD+ levels will help keep your cells ready to assist with all kinds of restorative action. From assisting with basic autophagy to helping rectify various forms of cell damage that come with aging, high levels of NAD+ can support cellular resilience across the board.
All in all, unparalleled repair capabilities make our cells biological superstars— and NAD+ boosting supplements can help support their function. Whatever your wellness regimen, take care of your cells. They constantly work to keep us healthy, energized, and resilient.
