As you age, you may notice that your body stop functioning the way it used to when you were young. You will observe many changes, be it the skin getting loose or catching diabetes. You may also observe decline in energy.

Generally people feel tired and low every now and then but they feel really well after a good night sleep. The problem comes when you feel so tired and sleepy continuously from weeks as if you don’t have any energy left to even do day to day stuff. This problem is called fatigue.

Fatigue in old age is very commonly faced by silver-haired citizen especially people having some medical problems. Endurance can decline with age but fatigue should not be considered as a natural process of ageing. Hence, it should not be considered that normal ageing and fatigue go hand in hand.

Dehydration is decreases alertness and concentration and it is recommended to drink as much as water you can daily. You might be asking how you could know that you are drinking enough water. The answer is checking your urine! If it is darker than pale yellow or straw colour, it is high time to make drinking water your habit.


We are hearing this phrases since childhood “Early to bed, early to rise, makes a man healthy, wealthy and wise”. But the amazing thing is that this old phrase makes sense even now. Good sleeping habits have amazing benefits. If you allow yourself to sleep early, you are more likely to sleep for a longer duration and ultimately you will feel less fatigue.


We completely understand that when you are feeling tired, exercise is probably the last thing you want to do. But studies have shown amazing benefits of exercise in old age. It will keep you energised all day long and will also keep your heart, brain and muscles healthy. Doing exercise on daily basis will reduce skeletal muscle fatigue in old age. But it should also be in mind that doing more exercise than you body capability may also lead to fatigue.


All over the world people have accepted the benefits of YOGA. Always remember that age is just a number and It is never too late to try something new. So even if you haven’t done yoga when you were young, you can give it a try now. Doing yoga can bring enormous change in your life. You will feel more confident, energetic and mindful.


As we have discussed above how medical problems cause fatigue. So the primary focus should be on curing those diseases which would ultimately cure problems like fatigue and weakness.


We suggest you to develop one habit at a time and that too slowly. For example don’t start going early to bed and doing exercising and taking smaller meals all together in a single day. Try to keep the pace slow but lasting. Try to change your routine one habit at a time as this will give you more lasting benefits.


Whenever you feel so tired, go for a 5-min walk, do stretch your legs and relax by appreciating the weather and the blessings you have. Try to remember the good things or your best moment you are always grateful for. This would give you a new ray of hope to live big and long. You can do this 2-3 times a day.


Taking high quality vitamins on a daily basis have amazing results on your body. It will keep you healthier. You can take the help of a doctor to get suggestions on which vitamins are beneficial for your body.


Our surrounding plays a major role on how we feel and act. If you surround yourself with people who encourage you, make you feel loved, people who care for you and want you, you will feel amazing with them. Try to spend more time with people who are worth your time instead of spending it with the ones who make you feel worthless and are energy draining.


It is very important to maintain relationships because ultimately only these are the real earnings. So try to meet your loved one frequently on dinner or a get together. You will feel a strange rush of energy in your body when you are surrounded by the people you love the most.


The main problem of depression and health issues comes when you don’t have anything to do whole day. You will get bored and start feeling useless. So we recommend you to be a part of an organisation or NGO who is working for a cause you always wanted to be a part of but haven’t got time when you were young. When you would have a gig to wake up in the morning, you can overcome fatigue more easily.

Assessment of Severity of Fatigue

Though there are many scales available for the detection of fatigue like Multi dimensional Assessment of Fatigue, etc. But still there is no solid device to check it.

But we have “Calder’s fatigue severity scale” to the rescue which is the most authentic of all. You have to rate each of the following question from 0 to 3:

  • Tiredness problem

  • Lack of energy
  • Lack of strength in muscles
  • Feeling weak
  • Difficulty in concentration

A total score of greater than 18 points out of a possible 33 points is considered highly suggestive of fatigue.


Fatigue should not be considered as a symbol of getting older because it is not. Fatigue is like a disease in itself which can be cured easily if taken care of, simply by changing our lifestyle and making a positive outlook of life .
