The following are additional tips on how to generally prevent fatigue as well as the effects it can bring.

#1 Be aware of your health conditions. As previously stated, fatigue is one common symptom of various health conditions such as heart diseases, arthritis, thyroid disease, diabetes, sleep apnea, and others. With that being said, it’s essential to talk to a physician to check why you feel tired often. This will help to understand the underlying cause of fatigue and do the preventions needed.

#2 Rehydrate, drink plenty of water. Water is vital in maintaining a good health condition of the body. Rehydration can help prevent fatigue to avoid decreasing concentration and alertness. Drink plenty of water and juices to prevent dehydration.

#3 Do some exercises and keep moving. You might be thinking about how exercise can aid in preventing fatigue. However, exercise is proven to be useful in boosting energy levels when doing physical activities. It is also required for some people who are experiencing some medical conditions such as diabetes. Aside from that, exercise is also medically advised to help improve the overall quality of life and work performance.

#4 Do some yoga and meditation exercises. Although most kinds of exercises are good, yoga may be specifically effective to help boost zest and energy. Many yoga and meditation classes aim to bring improvements in self-esteem, mindfulness,  energy, and physical performance.

#5 Have a great sleep. Get to bed early and make sure to get enough sleep. Lack of sleep may increase the chance of getting involved in accidents. This is also one of the major factors which cause daytime fatigue. When someone is at work yet feels sleepy, you can’t expect a good concentration and focus. There will be no clear thinking and worse, there can be some critical matters that may be overseen.

In case you had a not-so-good night sleep, you can take a brief nap in the afternoon. It is proven that napping can restore energy and promotes better learning and productivity. You can nap for 10 minutes, just enough to regain your energy. For some, a nap which is followed by a cup of coffee can be another excellent energy boost. Just remember to take coffee in moderate amount because too much of it can be a risk in your health.

#6 Eat healthy fish. There are certain types of fish which are rich in omega-3 oils. Choose these types of fish since they are good for your heart. Omega-3 oils also help boost alertness. A study in Italy's University of Siena, it was found out that volunteers who took a fish oil capsule for three weeks showed a faster mental reaction. Furthermore, they are also reported that they feel more vigorous and energized.

#7 Keep track and be aware of your body clock. Some people are often getting their burst of energy in the morning while some others are considered ‘night owls’ because they are more productive during the end of the day. These differences of individuals in daily energy patterns are analyzed by brain structure and genetics, both factors that are difficult to change. That is why we need to be aware of our circadian rhythms or ‘body clock.’ This will help you determine which part of the day you are most comfortable working so you can have a better schedule.

#8 Keep your weight within normal. Shedding off extra pounds can help provide a powerful energy boost.  Overweight people may experience difficulties with movements and energy. Health experts and nutrition advisors will advise to eat a balanced diet, and do some basic exercises to help in weight loss journey. Even a little reduction in body fat can improve vigour, mood, and quality of life.

#9 Eat more often (in small portions). Some people are confused when we say diet and nutrition. They sometimes put themselves in a diet that plan that instead of helping them to achieve a healthy body, this can be a source of some issues.

Besides, there may be some individuals that may benefit from taking in proper nutrition by eating smaller meals yet frequently during the day. In that way, your blood sugar level will be maintained properly. Choose whole grains and healthy foods with complex carbohydrates. Always choose foods that are healthy and good for the body.


Fatigue can be part of our daily lives, but it depends on us how to prevent it from causing further issues in our life. So, make sure to get informed and work to avoid it.
