Have you ever thought about how long you might live and what really decides that? Is it your lifestyle or more genetics? Or maybe the place you live in? Lifespan and life expectancy are two ideas often mixed up, but both are important for understanding our health. In modern times, it has become more important to learn how to manage it. Fortunately, there are many things we can do to improve our health and lifespan, and that will be the talk of this article.
So, without further ado, let’s jump right in!
Research Highlights
What is Life Expectancy?
Generally speaking, it is how long you expect to live on average and how healthy they will be in their old age. The average lifespan in 1900 was 47 years, although it has risen significantly. The current life expectancy for a person born in 2022 is 77.5 years.
Many factors contribute to this change, most due to improved medical care and accessibility. In 1851, the life expectancy of an English or Welsh citizen was below 50%. On the other side, the life expectancy of the English and Welsh population is above 95% right now.
Lifespan Vs. Life Expectancy Vs. Longevity
Let’s take the example of an old woman of 95 years for the sake of the argument. She, for sure, lived a long life and enjoyed all the moments with friends and family. This is an example of longevity. Now, when we talk about lifespan, we can talk about how long people can live. In other words, this refers to the maximum age that a human can potentially reach.
And when we talk about life expectancy, it is a bit different. It is a number that tells us how long people in a certain country or area are likely to live on average. So,
- Longevity shows how a person thrives through the years.
- The lifespan tells us the maximum potential of human life.
- Life expectancy gives us an average that helps us understand how long most people live.
The Recipe for Longevity: What Makes a Difference?
Different factors define life expectancy, such as genetics, gender, healthcare access, lifestyle, diet, and crime rates all count.
- Genetics: Some people think genetics is everything, but it is only partially true. According to a study, only 20–30% of a person’s life expectancy is related to genetics, while the rest is covered by lifestyle, diet, and other factors. The important things in genetics are that they help keep the telomeres on our chromosomes in good shape, fix DNA, and protect cells from oxidative stress, a type of damage that happens when cells make energy.
- Environment: Did you know where you live can make you live longer? It is known that people who live in certain “Blue Zones” around the world tend to be better and live longer. Okinawa (Japan), Ikaria (Greece), Sardinia (Italy), Loma Linda (California), and Nicoya (Costa Rica) are some of these places.
- Gender: It has also been documented that women live longer than men. This can be attributed to many factors, such as smaller bodies, which means less stress on the heart and fewer chances of developing cardiovascular issues. The second factor could be a better immune system because less testosterone is a better immunosuppressant, and three women might be less engaging in dangerous activities.
- Lifestyle Factors: A lot of different lifestyle choices have been linked to a higher risk of dying young. Poor nutrition, inactivity, smoking, and drinking too much are the main causes. But obesity, which raises the risk of many health problems and, eventually, death, is one of the most important lifestyle choices that affect longevity.
Steps to Increase Your Lifespan
While there may not be a magic bullet for extending one’s lifespan, studies have demonstrated that certain lifestyle modifications are associated with a greater likelihood of a longer life span. In fact, one study mentions that by bringing some good changes in your life, you could increase your lifespan by 20 years!
1. Follow a Good Nutritive Diet
Diet has a huge role in improving your health, ultimately increasing lifespan. Eating foods that are right for your body helps fight off disease, keep your cells safe, and repair any damage. On the other hand, foods such as sugar, harmful fats, and processed food make your cells vulnerable to damage.
So, what is the best diet to promote longevity? Research suggests that women who follow a plant-based Mediterranean diet live longer. This diet mainly focuses on veggies (not potatoes!), fruits, nuts, whole grains, legumes, and seafood. Those women who adhered strictly to this eating plan had a 23% lower risk of death from any cause than those who did not.
So, it is best to follow a plant-based diet for your lifespan. But that doesn’t mean you must give up meat entirely or cut out sweets. It means that foods with minimum processing should make up most of your diet.
2. Do Exercise
There are many benefits of exercise for your life and health to be counted. But one interesting study shows that people who exercise even 3 hours a week can live up to 6.9 years longer than people who don’t exercise at all.
If you want to maintain good health and live a long life, how much exercise do you need to do? The American Heart Association’s 2018 Physical Activity Guidelines suggest that people get at least
150 minutes of moderate exercise per week, 75 minutes of strenuous exercise per week, or a mix of the two.
But if you are over 60 and still want to do it, start immediately. A recent assessment found that those over 60 who exercised had a 22% decreased risk of premature mortality, even though they exercised less than the recommended time. For those who did reach the 150-minute goal, the risk of premature mortality dropped by 28%. Remarkably, 35% of individuals who exceeded this guideline experienced these benefits.
Moderate activity can be anything, including weight lifting, walking, and low-intensity training. While vigorous exercise means bicycling, jogging, and swimming. But if you are new to exercise and physical activity, even doing simple house chores like gardening and cleaning can be your exercise.
3. Have Some Time Outside
While we all think that spending time outside is just for taking a break from routine, it does have more health benefits.
Such as, when you step outside, you soal up some sunlight, and with it, your body produces vitamin D. This vitamin D production is very important for bone strength and production. However, according to studies, half of individuals with insufficient vitamin D levels just don’t spend enough time in the sun. Vitamin D levels can be maintained in healthy individuals with as little as 15 minutes of sun exposure daily.
Not only does spending outside boots naturally increase your vitamin D level, but it also makes you more social. Studies have shown that having strong social ties can make your lifespan better.
4. Stay Happy
A big part of living a long life is being happy. In fact, if you stay stressed, you can take a huge chunk of your lifespan. For example, the risk of death from cardiovascular disease, stroke, or lung cancer is up to twice as high in women who suffer from severe anxiety or stress. Similarly, men who are nervous or stressed out have a threefold increased chance of dying prematurely compared to those who are not.
But there is always a solution. Staying happy can increase your longevity. In fact, over five years, a study found that happier people had a 3.7% lower risk of dying young. A review of 35 studies also found that happy people may live up to 18% longer than people who are not.
It’s clear that being stressed out can be very bad for you, but being happy and optimistic can help you live a longer, better life.
5. Avoid Health Risks
Prevention is better than cure; we all have heard it. And its very much true in the case of life expectancy as well. These risks can be anything from accidents to chronic diseases. While accidents are more common at a young age, health problems are much more likely to be seen in later years of life. All this has been summarized in 2021 research,
| Health Factor | Years Lost |
|---|---|
| Prolonged sitting | 2-4 years |
| High blood pressure | 4-5 years |
| Being chronically underweight | 4-8 years |
| Smoking | 5-7 years |
| Alcohol abuse | 5-7 years |
| Physical inactivity | 5-7 years |
| Type 2 diabetes | 7-10 years |
We can significantly reduce these risks by adopting a healthier lifestyle, which will be discussed in the upcoming sections of this article
6. Follow a Good Lifestyle for a Better Lifespan
Many pieces of research have proven and believe that many lifestyle modifications can lead to better longevity. These factors include,
Quit Smoking: We are all well-versed by now with the harmful effects of smoking. It can severely damage your lungs, heart, and skin, as well as your dental function. Not to forget the serious effects it has in spreading cancer; even one research mentions that smoking one cigarette can reduce life by 11 minutes!
So, if you are not a smoker, it is better to refrain from it in the future. And if you are, the earlier you quit, the better it can be. One study indicated that people who kick the habit before age 35 may add up to 8.5 years to their expected lifespan. Numerous helpful resources are available to help you kick the habit, including medicine. You can even find some methods and tips in our article here.
Limit Alcohol: Like smoking, drinking alcohol has its health problems. As per NIAAAH, drinking to excess raises the danger of cancer, liver damage, and serious injuries. It also lowers immunity and might make you depressed. While it is okay to drink alcohol in moderation, even moderate drinking has health hazards; it can increase the risk by 17–18% in your risk of premature death. So, it’s preferable to drink even less or not drink at all.
Be a Social Butterfly: While it might be new, the probability of living a longer life is directly proportional to the frequency of socializing. A large study of 28,000 people found that people with more frequent participation in social activities lived longer than those without. In fact, having just three friends or family may cut your risk of dying young by more than 200%.
Another study showed that people’s health improves in correlation with the strength of their social networks. Not only this, but even a bigger study with 308,849 participants reported that having a strong social connection can reduce the risk of premature death by 50%.
So, prioritize your health by spending time with loved ones, participating in groups, attending events, or meeting for coffee. You may improve your health by connecting more.
7. Get Health Screening Tests
One of the most neglected aspects of your health is a health checkup. We all believe that we need to visit a doctor until it is required or we fall ill. But to be healthy and have a better lifespan, getting regular health examinations is a must. It can help you detect any health problem even before it begins. This is especially important if you have a family history of chronic diseases. For more detailed information on this topic, be sure to check out our in-depth article!
Not only this but also remember to maintain your immunization schedule! such as flu and COVID vaccinations.
