The Science of Longevity
Many teenagers especially girls are very concerned about aging. As a result, this post is especially important for you. The purpose is to educate youngster some basic knowledge of maintaining their young and youthful appearance, longevity of life and staying with a healthy lifestyle. I will try to put this post as elucidating as possible so everybody who read can at least grab more than 50% of what I write; although some scientific terms seem to be hard to understand, I will try to explain each and every of the definition as much as possible. Let's start with some of the easy one.
Ionizing radiation - When we are talking about ionizing radiation in regards to staying young, we are talking about the ultraviolet radiation (UV ray) emitted from the sun which destroy our skin cells. Although X-ray is also an ionizing radiation, we are not talking about that since just one X-ray scan doesn't do you as much harm as the daily exposure to UV ray from the sun. Despite providing us with Vitamin D (a coenzyme important for the correct formation of our born and absorption of calcium), UV ray can also damage our cells DNA (causing cancer or sunburn), killing our cells (damaging factor), reducing the collagen in our face (more crevice formation that make us look older), causing free radical on our cells (free radical are high energy electron or ions that damage our cells such as destroying the DNA and this may cause benign or malignant tumors whereas malignant tumor is definitely a cancer). To stay young, it is advisable for you to put on sunscreen or lotion with zinc and antioxidant ingredient when you are exposing to the afternoon sunlight. Take note that UV ray can pass through some umbrella, the purpose of umbrellas are to shed visible light but not UV ray so do not assume that you are protected if you have an umbrella.
Antioxidant - As mention in the previous paragraph, what is antioxidant? Free radials are generated from your body during metabolism or when you are exposed to ionizing radiation. Free radials cause damages to the cell, sometime it can be so serious such that the cell becomes cancerous. The purpose of antioxidant is to neutralize the free radical so that there are lesser free radical in our body, thus lesser harms and therefore slower aging. To stay young, eat antioxidant such as lipoic acid, Vitamin C and E TOGETHER with many types of fruits and vegetables. You cannot totally depend on supplement as there are over 100 types of chemicals in fruits that work together to scavenge free radicals from your body.
Carbohydrate - Eating less carbohydrate can lead to longevity since glucose restriction means slower metabolism in our cells. When our cell metabolism slow down, lesser free radials are produced, thus, we will age slowly since there are lesser damages on our body. For some girls who are on high carbohydrate and fats restriction, because you are afraid that you may become fat even though you are underweight, you may have Anexoria nervosa. I have seen some of my teen friends who look normal weight as they restrict diet but have gastric problem after doing this for long term and they are still restricting carbohydrate. This is not the right way of doing since they will not get enough nutrient from food, thus slowing their growth rate during their puberty time. The right solution is to eat moderately, not too much such that it can gain you much fats or too little that can cause you gastric pain. Your existing health is your first priority but not spoiling one system for the purpose of losing weight. Strictly do not eat medical pills to slim down other than vitamins and minerals. Medical pills are harmful/cannot be trust, they can damage your livers and kidney for long term consumption. If half of your liver or kidneys are damaged, you wouldn't know since no symptoms will appear until 90% of it is damaged so you need to be careful.
Having enough sleep - Sleeping (not resting) is very important. While we are sleeping, our cell metabolism slow down, lesser free radials are produced. Therefore, people who sleep enough will look younger. When we are sleeping, our body undergoes a few cycle of random eyes movement, it is where our body becomes active, idle, active, idle, many repeating cycle for every few hours. This is the lay man term, in scientific terms, it is more than this but idle body does not happen when you are resting, except that when you are sleeping. Not only sleeping for a long time, a person must sleep at the right time; it means you sleep when you are sleepy but not sleeping too lately as it can affect your body clock. When your body is producing melatonin preparing for you to sleep, you force high production of Epinephrine while your body is producing melatonin at the same time. Does that make you feel actively drowsy; confused?
