Biological Signs of Aging

Biological Signs of Aging

The biological signs of aging appear in our bodies in a  very logical order and  we all experience them. The signs of aging  are the things we see changing in our bodies as we get older.  Logic says you and I cannot stop these aging signs. But I will show you how to slow them down. Then you can join me and age gracefully and well. The list below has things we see and feel happening every day of our lives. I think you will agree they are like dominos.

Top 10 Biological Signs of Aging

  1. Decrease In Muscle Mass

     If you are less active than you used to be, then  you probably  are experiencing  a loss of muscle mass. This does not happen because you are getting older. It happens due to lack of activity. Remember the expression…”If you don’t use it, you lose it!”

  2. Decrease In Strength

     Less muscle mass will lead you to experience a decrease in your strength. I lost most of my strength in few short months just prior to having open heart surgery du to a lack of activity.

  3. Slowing of Metabolic Rate

    Less muscle, as the majority of middle aged  and older people have,  leads to  a decrease  in your need for oxygen and calories. Muscle tissue is active tissue and needs nutrients.

  4. Increase in Body Fat Percentage

    If  we lose muscle tissue the our body fat a a percentage of our body mass increases. In addition most of us don’t change our eating habits easily so less activity means less energy use. But if we still eat the same way,  then we’re adding fat or storage cells.

  5. Decrease In Ability To Use Oxygen (aerobic capacity)

     This is the ability to rapidly breathe amounts of air into the lungs  for aeration of the blood. To deliver large volumes of blood  by the pumping of the heart. And  to transport oxygen throughout your body by a strong vascular system. For example, you may find it getting harder going up the same flight of stairs, getting up from a chair or up off the floor! This happened to me over several months.

  6. Blood Sugar Intolerance 

    As we age, we can gradually  lose the ability  to efficiently use the sugar in our blood.  Then our blood sugar rises and this may  increase  our chance of developing Type 2 Diabetes.

  7. Increasing Cholesterol

      Cholesterol  is not a required substance in our diet because  our body is able to produce what it needs.  Cholesterol is a fatty substance that’s essential in  the construction of cell membranes.  Sometimes it can collect and form deposits in tissues.  When this happens in your  blood vessels, it is called ‘atherosclerosis’.  This condition contributes to the development of heart disease.  Cholesterol in our diet comes from animal food sources;  there is no cholesterol in plant food.  High cholesterol is largely caused by bad dietary  habits like eating too much fat and salt.

  8. Increased Blood Pressure

    While this may be partially hereditary, contributing factors are obesity, eating too much fat and salt, drinking too much alcohol and too little exercise. Blood pressure is measured in two parts. The first, systolic, is the pressure the blood exerts on the walls of the arteries when the heart contracts. Secondly, diastolic, is between beats when the heart is taking a rest. If the diastolic is raised your arteries never get a rest. They are constantly stressed, and over time the walls may thicken and stiffen.

  9. Decrease In Bone Density

    Aging produces a decline in the mineral content of bones that leaves  a weaker, less dense,  more brittle skeleton.  When this reaches the point where there is a large increase in the risk of fracture, it’s called  osteoporosis.  By the time this occurs some people are old, feeble and frail.  As the signs of aging become more prevalent, older people are apt to suffer from falls because of poor balance and weak muscles.  Then serious injuries may be the result. They have  poor muscles,  poor balance  and  brittle bones. Any fall can then be devastating!

  10. Decreasing Ability To Control Internal Temperature

     Our bodies have an excellent  temperature control system.  If it is too hot, the main cooling mechanism is to sweat. The evaporation of the sweat cools the body. If it is too cold, the body shivers which  generates heat. Both help maintain the 37.5 C or 98.6 F required. To do this properly you need the correct amount of water and blood flow. An imbalance here shows up as the gradual loss of effectiveness of this system. 

    It seems that as we age our sensations of thirst decline so we don’t drink enough water. The lack of exercise leads to a lower heart rate and a smaller heart stroke volume (we don’t pump enough blood). This means less blood flow to the skin. I have read that it takes a higher internal temperature to make an older person sweat. The combination means your body may not be able to efficiently maintain a healthy, comfortable temperature.

Conclusion

These biological signs of aging are happening to all of us and we can work to delay them. Your knowledge of these markers can help you push up your Aging Curve! Now, if you are new to fitness, this information will help you understand what is happening to you and how you can push back against your own aging curve as I am.
