Fatigue is an enemy of productivity and potentially having a fulfilling life. It has long been thought that fatigue is something that comes about with age, but experts are starting to rethink the idea that fatigue is, in fact, not an expected part of aging at all.

A closer look into our own lives shows us fatigue can come from anywhere: from depression, stress, and boredom to medications like antihistamines or beta-blockers. Then there is deconditioning, which basically means you’re out of shape, leading you to feel more fatigued.

If your fatigue is caused by a serious health condition, then obviously that needs to be addressed. If not, then there are some changes you can make in your lifestyle to ward off fatigue.

Increase activity

For fatigue caused by inactivity and/or deconditioning, bumping up the movement can help a lot. You don’t have to go out and try to run a marathon; take it easy, just focus on getting up more, walking, gardening, taking the stairs, et cetera.

Keep track of what you eat and drink

You should especially watch out for high-sugar and fried food, as well as alcohol and caffeine. While you’re at it, try some fatigue-fighting snacks like edamame, melons, and nuts. These are all packed with vitamins, nutrients, and minerals that are known to boost and maintain one’s energy.

Explore your interests

Boredom can be another source of fatigue—one that works like a vicious circle. If you’re bored, it can add to fatigue, which makes it harder to fight the boredom, which makes one feel more fatigued–you see where this is going.

To fight boredom, tap into your interests and explore the options: find a new hobby or resume an old one, join or start a group or club, or just get more involved in the community.

Improve your sleep

While fatigue isn’t always caused by too little sleep, improved sleep duration and quality for those who struggle is a good place to start.
