Fatigue is a widespread problem, making daily functions such as work and visiting family members difficult. By recognizing common causes of fatigue, you can make the appropriate lifestyle changes and take your energy back!

A Sedentary Lifestyle

Many people skip their workouts because they are already tired. Oddly enough, you are more likely to experience fatigue if you do not exercise. Exercise naturally boosts your energy by balancing your hormones and increasing bloodflow, which then increases oxygen. Additionally, exercising early in the day can improve your sleep quality.

Your Phone

The blue light wavelengths emitted by screens on smartphones, computers, tablets, and TVs tell your brain not to produce melatonin, a hormone which regulates your sleep/wake cycle. In other words, scrolling through social media or watching fail videos before bed can actually make it harder to fall asleep and stay asleep. Try to stay away from screens for 30-60 minutes before bedtime—this is a great opportunity to start reading that book you’ve been meaning to get around to!

Carbon Monoxide

Your fatigue may be caused by the presence of toxic carbon monoxide in your home. Carbon monoxide is a colorless, odorless gas produced by water heaters, HVAC systems and fireplaces. It is often called the silent killer because many people do not know that they have it in their home until it’s too late. Early symptoms of carbon monoxide poisoning include:

  • Easily getting out of breath
  • Fatigue
  • Nausea
  • Confusion
  • Headaches
  • Dizziness

If you have a home security system, having something like ADT monitored carbon monoxide sensors installed can keep track of the carbon monoxide levels in your home. If you don’t have a sensor installed, consider getting one ASAP.


Dehydration can cause fatigue and sleeping problems. When you are dehydrated, your blood volume decreases, which in turn causes your heart to pump less efficiently. When your heart isn’t pumping as well, this decreases the flow of oxygen and nutrients to your tissues and organs. Keep a bottle of water with you at all times to help combat dehydration-related fatigue.


Red blood cells are responsible for distributing oxygen throughout your body. If you are anemic, then your body does not produce enough red blood cells, or may not be making them correctly. Anemia is one of the top causes of fatigue in women, especially for those who regularly experience heavy menstruation.

Sleep Apnea

Sleep apnea is a disorder that causes one to stop breathing for brief periods at night. Because your sleep is constantly being interrupted, it can be difficult for you to get enough sleep, resulting in a constant state of fatigue. Anyone who is constantly tired during the day or obese should be checked for sleep apnea.


Stress can cause you to feel mentally and physically exhausted throughout the day, especially if worrying keeps you up at night. Practicing meditation, journaling, keeping a checklist, and exercising are popular ways to alleviate stress and therefore reduce fatigue.

Fatigue doesn’t have to be part of your life. Sleep apnea, screens, stress, dehydration, carbon monoxide, a lack of exercise, and anemia are some of the issues that can cause fatigue. Resolving those problems will help you sleep better, boost energy, and increase motivation.
