Decision fatigue: the hidden energy drain no one talks about

If you often feel mentally exhausted before the day is even over, you might be dealing with something most women don’t even know exists: decision fatigue.

It’s not just about big choices like changing jobs or moving house. Decision fatigue comes from the hundreds of micro-decisions women make every single day, what to cook, whether to exercise, how to respond to an email, when to book that appointment, or which bill to pay first.

Each decision might seem small, but the constant mental juggling quietly drains your energy stores. By the time evening rolls around, you’re not only physically tired, but mentally tapped out.

Why women are especially vulnerable

Research shows the average person makes over 30,000 decisions a day. For women in their 40s, 50s, and 60s, that number often feels doubled. Why? Because many women are carrying what’s known as the “mental load” — the invisible responsibility of managing households, caring for kids or ageing parents, juggling careers, and looking after their own health.

It’s not just the doing, it’s the remembering and anticipating:

• What’s in the fridge and who’s going to eat it?
  

• Which child has sports practice, and who’s picking them up?
  

• Whether Mum’s prescription needs renewing.
  

• How to fit in exercise around meetings.

Even before you act on them, the sheer number of decisions chips away at your mental energy.

The science behind decision fatigue

Decision fatigue is more than a buzzword. Studies in psychology and neuroscience show that the brain’s ability to make decisions declines after repeated use, much like a muscle that tires with exercise.

When decision fatigue sets in, you’re more likely to:

• Make impulsive choices (hello, 5 pm pantry raid).
  

• Avoid making decisions altogether (leaving tasks unfinished).
  

• Feel irritable, overwhelmed, or mentally foggy.

For midlife women already dealing with shifting hormones and increased stress, this constant drain makes fatigue even harder to manage.

Practical strategies to reduce decision fatigue

The good news is that you don’t need to eliminate all decisions. The key is to reduce unnecessary ones and create supportive routines that give your brain a break.

• Simplify meals: Rotate a handful of family favourites or plan the week in advance. Decision made once, not seven times.
  

• Automate where possible: Set bill payments, use reminders, and create recurring grocery orders.
  

• Set boundaries on choices: Not every option needs to be considered. Narrow your wardrobe, stick to two breakfast options, or limit screen time apps.
  

• Schedule brain-off time: A short walk, meditation, or even a cup of tea without multitasking gives your mind space to reset.
  

• Share the load: Decisions don’t have to rest on your shoulders alone. Involve partners, children, or colleagues where you can.

Final thoughts

Decision fatigue is a hidden energy drain that often gets overlooked. It’s the natural result of asking your brain to carry too much, too often. By lightening the daily decision load, you free up mental energy for the things that really matter. And that’s one of the simplest ways to reclaim clarity, calm, and vitality in midlife.
