Comprehensive list of the effects of aging

We all know age creates significant changes in the body, but what exactly is happening as we get older? Here's a comprehensive list of the effects of aging.

According to the world health organization, the world’s population aged 60 and older will double by 2050. This trend puts great importance on the pursuits of healthy aging, and how we're going to increase the healthspan of our older populations. Aging effects the body in many ways, and understanding these changes is key to finding strategies to that help manage these effects and optimize our health. Here is a comprehensive, and ever evolving, list of the effects of aging.


The dermis (skin) is the largest organ in our body, comprising nearly 15% of our body weight. It’s the most visible part of our bodies, the most exposed to our external environment and it’s showcases the most noticeable effects of aging. These effects predominantly manifest as dryness, discolouration, wrinkles, and overall skin health.

Hair and Nails

Hair is abundant, with nearly 5 million hairs distributed across an adult body. The qualities and appearance of hair changes significantly with age, making it one of the most noticeable areas of aging. Nails grow similarly, and experience their own unique effects of aging.


Our cardiovascular system is crucial in supplying our body with blood and oxygen. This system effects our entire body, and has pronounced effects on our muscles and organs. The effects of aging are significant and lead to some of the biggest health challenges we face.


The muscles, bones, ligaments and tendons are responsible for the structure and functional operations of the body. Our activity levels and overall mobility are greatly affected by aging in this system.


The brain is made up of billions of neurons and other cells that are connected to each other. As we age multiple changes happen in the structures and cells of the brain which can lead to cognitive decline such as memory loss or dementia.

Vision and Hearing

Our main inputs to the world reside in our ears and eyes. With age their ability to process sound and images diminishes and changes the way we interact with the world around us.

Reproduction and Hormones

The reproductive and hormonal systems are responsible for our ability to procreate and change dramatically with age. These hormonal changes represent some of the biggest milestones in human aging.


Immune System

The immune system is an important system to regulate healing in our body. With age these systems experience loss of function and lead to increased incidence of injury and disease.

Cellular Health

Inside all parts of the body are cells, and the ability of these cells are crucial to all functions of the body. Many of the broad effects of aging can be traced back to the cellular level.


Healthy functioning organs are crucial for overall health. Organs use blood, cells and muscle tissues like many parts of the body but manifest the effects of aging in their own unique ways.

Urinary tract

There are many diet and lifestyle factors that can help slow down these effects of aging, but unfortunately our bodies still get older every day. But there are some strategies to intercept the aging process and preserve younger cells to use in regenerative medicine to help our bodies recover and fight these effects of aging.
