Why Your Energy Changes as You Get Older — And What You Can Do About It

Have you noticed that your energy levels aren't quite what they used to be?

Perhaps you can still have a busy day, go out in the evening and get up the next morning feeling fine, but maybe you now need a little longer to recover. Or you find yourself craving more downtime than you did a few years ago. You might even find yourself thinking, "Why am I so tired? I haven't actually done that much!" The good news is that changes in energy are common as we get older. And while getting older can bring some changes to the way our bodies function, it doesn't mean we simply have to accept feeling tired all the time. There are plenty of things we can do to support our energy, strength and overall wellbeing.

1. Make strength training part of your routine

As we age, we naturally lose some muscle mass and strength unless we actively work to maintain it. This is one reason resistance exercise becomes increasingly important as we move through midlife and beyond.

The good news is that you don't need a gym or lots of expensive equipment. Your own body weight, a resistance band or a couple of light weights can be enough to get started.

Three simple exercises to try at home

Sit-to-stands: Sit on a sturdy chair and stand up, then slowly lower yourself back down. Try 8–12 repetitions. This works your legs and glutes and supports everyday strength.

Wall press-ups: Stand facing a wall with your hands at shoulder height. Bend your elbows to bring your chest towards the wall, then push away. Try 8–12 repetitions.

Bicep curls: Use light dumbbells or two water bottles. Keep your elbows close to your body and slowly curl the weights towards your shoulders, then lower with control. Try 8–12 repetitions.

You don't need to do everything at once. Start with two or three exercises a couple of times a week and gradually build up as you become stronger.

If you're new to resistance exercise, have an injury or health condition, or aren't sure whether an exercise is suitable for you, seek advice from an appropriately qualified professional before starting.

2. Don't underestimate the importance of sleep

You might be spending enough time in bed but still not feel properly rested. Sleep can change as we get older, and hormonal changes, stress, alcohol and waking during the night can all affect the quality of our sleep. Rather than focusing solely on the number of hours you're getting, think about your overall sleep routine. A regular bedtime, getting outside during the day, limiting alcohol close to bedtime and creating some quiet time before bed can all help. If you're consistently struggling with sleep, it's worth looking at what's behind it rather than simply accepting it as something you have to put up with.

3. Eat to support your energy

It's easy to grab something quick when we're busy, but what we eat can influence how we feel throughout the day. Try to include a source of protein, fibre and healthy fats in your meals and don't forget the basics such as drinking enough water. A breakfast of Greek yoghurt, berries, oats and seeds, for example, can provide a nourishing start to the day. You don't need a perfect diet. It's the overall pattern that matters.

4. Keep moving but allow yourself to recover

Exercise is important for our physical and mental wellbeing, but more isn't always better.

You may find that your body doesn't appreciate doing a hard workout every day in quite the same way it once did. Recovery becomes increasingly important.

Walking, swimming, yoga, Pilates, dancing, gardening and strength training all count as movement.

Listen to your body and give yourself permission to have quieter days too.

Rest isn't laziness. Recovery is part of looking after yourself.

5. Look at what's using up your mental energy

Physical tiredness isn't the only kind of tiredness. Constantly thinking about work, family, finances, appointments, caring responsibilities or other people's needs can leave you feeling completely drained, even when you've barely moved all day. Sometimes what we need isn't another coffee or another workout. We need to switch off. Try building small pockets of genuine downtime into your day. Put your phone away. Sit outside. Go for a walk without listening to anything. Read a book. Spend time doing something that makes you feel like you.

6. Get outside

There is something wonderfully simple about getting outdoors. Natural daylight, fresh air and movement can all help us feel more alert during the day, while spending time in nature can also provide a valuable mental break. It doesn't have to be a long walk. Ten or fifteen minutes outside can be enough to interrupt a sedentary day and give you a change of scene. And if you can combine it with something you enjoy,walking through the countryside, gardening or meeting a friend for a stroll, even better.

7. Don't simply put persistent tiredness down to getting older

While it's completely normal for our energy levels to change throughout life, persistent or unexplained fatigue shouldn't automatically be dismissed as ageing. There can be many reasons for ongoing tiredness, including poor sleep, stress, nutritional deficiencies, hormonal changes, medication or an underlying health condition. If you're experiencing significant or persistent fatigue, particularly if it's a change from your usual level of energy, speak to your GP so that any underlying causes can be explored.

Getting older doesn't mean running out of energy

Perhaps the biggest shift is recognising that looking after our energy isn't about trying to be the person we were at 20, 30 or even five years ago. It's about understanding what your body needs now. Maybe you need more recovery. Perhaps strength training has become more important. Maybe you need to protect your sleep, eat a little differently or create more space in your day. And that's not a failure,it's simply part of getting to know your body as it changes. You don't need to overhaul your life. Small, consistent changes can make a real difference to how you feel.
