Can and could all humans live to 100 or beyond?
Lifestyle Choices
Diet
Certain dietary changes can extend one’s life expectancy, a new study from the GBD confirmed
A diet rich in legumes and whole grains can add up to 1 decade to a person’s life if they start eating for longevity early enough.
Physical Activity
A study from the University of Harvard analyzed 30 years of medical records and mortality data from over 100,000 adults.
Following the minimum physical activity guidelines (150-300 minutes of moderate-intensity or 75-150 minutes of vigorous-intensity activity per week) reduced the risk of early death by up to 21%.
Exercising two to four times the minimum guidelines further lowered the risk, up to 31%.
Tobacco & Alcohol Consumption
Harvard University conducted a study to determine the correlation between alcohol consumption and longevity
Adults drinking seven to 14 drinks per week could expect, on average, a six-month shorter life expectancy as of age 40
Those drinking 14 to 25 drinks per week could expect a shorter life expectancy by one to two years
Those drinking more than 25 drinks per week could expect a shorter life expectancy by four to five years
Sleep Patterns
In a study conducted by ACC, men and women who reported having all five quality sleep measures (a score of five) had significantly greater life expectancy.
Men with all five favorable elements of low-risk sleep had an increase in life expectancy of 4.7 years, while women had an increase of 2.4 years, compared to those who had none or only one of the five measures.
Further research is required to understand why men with all five low-risk sleep factors experienced twice the increase in life expectancy compared to women with the same quality sleep.
Sun Protection
Sun exposure can affect multiple hallmarks of aging
Moderate sun exposure, particularly through infrared rays, can help prevent or mitigate mitochondrial dysfunction, altered cellular communication, and nutrient sensing, which are hallmarks of aging (Wong et al., 2019)
Modest amounts of sun exposure have been associated with reduced inflammation, potentially preventing or reducing the severity of age-related diseases
The positive effects of sun exposure on aging and inflammation have been supported by research studies
Stress Management
Prolonged stress increases the risk of various health disorders, including heart disease, addiction, mood disorders, and post-traumatic stress disorder.
Stress can impact metabolism, accelerating obesity-related conditions like diabetes.Stress impairs emotional regulation and cognitive function.
A study led by Rajita Sinha and Zachary Harvanek from Yale University investigated the relationship between stress and aging.
The study involved 444 individuals aged 19 to 50 and evaluated age-related chemical changes and health markers. Participants who experienced chronic stress exhibited accelerated aging markers and increased insulin resistance, even after accounting for other factors like smoking, body mass index, race, and income.
Socioeconomic Factors
Healthcare
Restricted access to healthcare can negatively impact longevity.
Lack of timely and appropriate medical interventions can lead to untreated or poorly managed health conditions, reducing life expectancy.
Limited access to preventive care, screenings, and vaccinations may result in undetected or unaddressed health issues, potentially shortening lifespan.
Delayed or inadequate healthcare can result in the progression of diseases, leading to higher mortality rates.
Restricted healthcare may disproportionately affect vulnerable populations, exacerbating health disparities and impacting longevity.
Education
Women with the highest education level had a life expectancy at age 25 of 63.6 years, while those with the lowest education level had a life expectancy of 58.1 years, creating a gap of 5.5 years.
The life expectancy gap between the highest and lowest education levels decreased with age: 4.7 years at age 45, 3.3 years at age 65, and 1.6 years at age 85.
Men experienced larger relative differences in life expectancy based on education level compared to women.
Men with the lowest education level had a 15-25% reduction in life expectancy, while women experienced a 10-20% reduction (Welsh J 2021)
Employment & Working Conditions
The Oxford University study utilizes data from the German Socio-Economic Panel (GSOEP), a longitudinal survey representative of Germany.
Occupations with strenuous conditions are associated with higher mortality risks in later life.
The impact of strenuous occupations on mortality risks is more significant for women compared to men.
Other factors, such as being male, having poor self-assessed health, and having an officially recognized disability, also contribute to increased mortality risks.
Nutrition Security
Restricted nutritional security can have a negative impact on longevity.
Inadequate access to a nutritious and balanced diet can lead to malnutrition and related health complications.
Lack of essential nutrients and micronutrients can weaken the immune system and increase the risk of diseases, potentially shortening lifespan.
Restricted nutritional security may contribute to stunted growth, impaired development, and increased vulnerability to infections, all of which can impact overall health and longevity.
Socioeconomic disparities and food insecurity are factors that can contribute to restricted nutritional security and its consequences on longevity.
Environmental Quality
Air Quality
Air pollution reduces average life expectancy by almost as
much as tobacco use.
Air pollution-attributable life expectancy losses were greatest in Oceania, South Asia, and sub-Saharan Africa, where LE loss can be as high as 2 to 2.8 years for some countries.
The countries with the greatest life expectancy losses linked to air pollution were Papua New Guinea (3.2 yr), Niger (3.1 yr), and Somalia (3.04 yr). (State of Global Air, 2019)
Water Quality
Exposure to hazardous substances in the environment can have negative effects on longevity.
Contact with harmful substances such as chemicals, pollutants, or toxins at a construction site or other environments can lead to various health problems.
Prolonged or intense exposure to hazardous substances can increase the risk of developing respiratory diseases, cancer, neurological disorders, and other chronic conditions.
Inadequate protective measures or safety protocols can exacerbate the harmful effects of exposure.
The severity of health impacts depends on the type and level of hazardous substances, duration of exposure, individual susceptibility, and access to proper medical care.
Minimizing exposure to hazardous substances through appropriate safety measures and regulations is crucial for protecting workers' health and promoting longevity.

Climate & Weather Conditions
Body temperature is one of the most well known and important factors involved in lifespan
Increased body temperature has been shown to negatively associate with longevity (i.e. earlier death) and conversely, lower body temperature is associated with increased longevity and reduced aging.
(Holmer B, 2023)
Noise Pollution
In a 2011 study published in the journal “Environmental Health Perspectives”, researchers found that long-term exposure to traffic noise may reduce life expectancy.
Areas with daytime traffic noise over 60 decibels have significantly higher mortality rates.
Noise pollution has the potential to shorten life.
Night-time noise exposure over 55 decibels can lead to increased levels of the stress hormone cortisol.
Elevated cortisol levels over time can contribute to health issues and reduce overall life expectancy.
Studies highlight the direct link between noise exposure and the risk of premature death.
Social and Behavioural Factors
Social Support
Having strong social connections and support systems can contribute to better physical and mental well-being.
Social support provides emotional comfort, reduces stress, and promotes healthy coping mechanisms.
Engaging in meaningful social interactions can enhance the overall quality of life and promote healthier lifestyle choices.
Social support networks can provide practical assistance, such as help with daily tasks, healthcare access, and adherence to medical treatments.
Loneliness and social isolation, on the other hand, are associated with increased mortality risk and poorer health outcomes.
Cultivating and maintaining strong social support systems can play a vital role in extending lifespan and improving overall health.
Social Integration
Active involvement in social activities, community engagement, and maintaining strong social ties can have positive effects on health and well-being.
Socially integrated individuals tend to have better physical and mental health outcomes.
Social integration provides opportunities for social support, reducing stress, and promoting healthy behaviors.
The sense of belonging and connectedness derived from social integration contributes to a higher quality of life and overall longevity.
Conversely, social isolation and lack of social integration are associated with increased mortality risk and poorer health outcomes.
Prioritizing social connections and fostering social integration can contribute to a longer and healthier life.
Health Literacy
Sophie Bostock conducted an investigation where health literacy was categorized as high (67.2%), medium (20.3%), or low (12.5%).
During the follow-up period (mean 5.3 years), there were 621 deaths. The high health literacy category had 321 deaths (6.1%), the medium category had 143 deaths (9.0%), and the low category had 157 deaths (16.0%).
After adjusting for various factors, including personal characteristics, socioeconomic position, baseline health, and health behaviors, participants with low health literacy had a hazard ratio of 1.40 for all-cause mortality compared to those with high health literacy.
Participants with medium health literacy had a hazard ratio of 1.15, which was not statistically significant..
Medical Guidelines
Following medical guidelines can positively impact longevity.
Adhering to evidence-based guidelines for preventive care, screenings, and treatments can help detect and manage health conditions at early stages.
Proper adherence to prescribed medications and treatment regimens can improve disease management and reduce the risk of complications.
Regular check-ups and recommended health screenings can lead to early detection of diseases, increasing the chances of successful treatment and improved outcomes.
Following lifestyle recommendations such as maintaining a healthy diet, engaging in regular physical activity, and avoiding harmful habits can contribute to better overall health and longevity.
Compliance with medical guidelines can help individuals optimize their health, prevent diseases, and potentially extend their lifespan.
