If you're tired all the time, it's tempting to look for a clever fix: a supplement, a new coffee routine, an energy drink. Most of the time the real answer is duller and more useful. Sleep, stress and recovery.
Get these wrong and training stalls, eating slips and your mood goes with them. Get them right and you'll often find the rest gets easier without any extra effort. This guide covers how to sleep better, how to handle stress, how to recover, what a bad night costs you and when to talk to your GP.
Why energy drops after 40
It's rarely one cause. A few usual suspects: less sleep and worse sleep, more stress and responsibility, more sitting, a bit more alcohol and caffeine, less muscle, and recovery that takes longer than it used to. Most of these can be improved. Before you assume it's age, check the basics.
Sleep is the foundation
Most sleep guidance for adults says at least seven hours. Plenty of men over 40 get far less, then run on coffee and willpower. Shift workers, parents and anyone with a demanding job will know how hard it is. You can't always control how long you sleep, but you can protect the conditions.
Sleep runs in cycles of roughly 90 minutes, moving between lighter and deeper stages. Waking briefly between cycles is normal. What matters is how quickly you drop off again and how much deep sleep you get, which is why habits around bedtime matter as much as the number of hours.
Eight sleep habits that work
- Keep a regular wake-up time. This is the single most useful anchor. Go to bed when you're sleepy, but get up at the same time every day, weekends included.
- Get daylight early. Ten minutes outside in the morning helps set your body clock. It also helps you feel sleepy at the right time that night.
- Cut caffeine early. Caffeine can stay in your system for many hours. For most people, nothing after lunchtime is a good test.
- Be wary of alcohol. It can help you nod off, but it tends to break up your sleep later in the night. If your sleep is poor, try a few weeks without it.
- Keep the bedroom cool, dark and quiet. Around 16 to 18 degrees is often suggested. Blackout curtains or an eye mask help.
- Build a wind-down. Thirty to sixty minutes of something calm. Dim lights, a shower, a book, stretching. Put the phone out of arm's reach and, if you can, out of the room.
- Don't lie awake fighting it. If you can't sleep after about 20 minutes, get up, sit somewhere dim and read something dull until you feel sleepy. Staying in bed frustrated teaches your brain that bed is for worrying.
- Keep naps short. If you need one, 20 minutes before mid-afternoon won't wreck your night.
If you wake at 3am
It's very common. Your mind starts running through work, money, family. Keep a notebook by the bed and write down what's bothering you, then tell yourself you'll deal with it in the morning. Getting it out of your head and onto paper really does help. Then use slow breathing: in for four, out for six to eight, for a few minutes. Don't check the clock.
Calm is trained
Musashi wrote that you should keep the same steady mind in everyday life that you'd keep in a fight. It sounds mystical, but there's a practical idea in it. Calm under pressure isn't a personality trait. It's trained, in small doses, long before you need it.
Here's a simple way to practise. Take five slow breaths, making each out-breath longer than the in-breath. It takes about a minute. It lowers the volume on a busy head, and it teaches your body that you can choose to slow down. Do it at set times, such as before you pick up your phone at night or before a tough meeting, and it becomes available when things actually go wrong.
Know what you can control
A lot of stress comes from carrying things you can't do anything about. A simple habit: once a day, write down what is worrying you and sort it into two lists. What I can influence, and what I can't. Pick one small action for the first list. Let the second list go, or at least stop rehearsing it at 2am. It's an old idea, and it still works.
Stress you can feel in your body
Stress isn't only in your head. Tight shoulders, a clenched jaw, shallow breathing, a racing mind at night. Notice these as early warning signs. Then use the cheap, fast fixes:
- Walk. Ten minutes outdoors does more for stress than most apps.
- Breathe out slowly. A long, relaxed out-breath tells your nervous system it's safe to settle.
- Get outside. Green space, daylight and a change of view all help.
- Move. A short strength session or a brisk walk burns off tension.
- Talk to someone. A mate, your partner, your GP. Men tend to carry it alone for too long.
Stress is also about what you agree to
Manson's point about choosing what to care about applies here. You can't give your full attention to everything. Be ruthless about what you agree to. Learn to say "no" or "not now" without a long explanation. Look at your week and ask which commitments you'd drop if you had to. Then drop one.
Recovery is part of training
You don't get stronger in the gym. You get stronger in the recovery afterwards. If you're sleeping badly or running high on stress, you may need a lighter week, not a harder one. Walk more, lift lighter, go to bed earlier. That isn't weakness. It's strategy, and timing mattered a great deal to Musashi. We cover the training side in the Strength Training guide.
An energy audit
For one week, at the end of each day, rate your energy from 1 to 10 and note three things: how you slept, what you ate and how much you moved. You'll start to see your own pattern. Maybe a big lunch wrecks your afternoons. Maybe three late nights in a row is your limit. Your own data beats generic advice.
Movement, light and food
These all feed your energy too. Walk most days, get daylight, eat regular meals with enough protein and don't skip breakfast and lunch then crash at 4pm. See the Nutrition guide for more.
A four-week energy reset
- Week 1: fixed wake-up time, and five minutes outside within an hour of getting up.
- Week 2: no caffeine after lunch, and a 30-minute wind-down before bed.
- Week 3: five slow breaths at night, and a worry list before bed.
- Week 4: drop one commitment, and try a fortnight with less alcohol.
Keep the earlier habits going each week. To make them automatic, use habit triggers: "After I put my phone on charge, I take five slow breaths."
When to see your GP
Don't try to fix everything yourself. See your GP if you have:
- Persistent exhaustion that doesn't improve with better sleep.
- Loud snoring with gasping or pauses in breathing, or you wake unrefreshed. This can be sleep apnoea, which is common in men and treatable.
- Low mood, loss of interest, or anxiety that lasts for weeks.
- A sleep problem that's gone on for more than a few weeks.
You can also ask whether blood tests make sense to rule out things like thyroid problems or low iron or B12. If you're struggling emotionally, call Samaritans free on 116 123, any time.
Using caffeine well
Coffee isn't the enemy. Used well, it's a useful tool. Have it after you've been up for an hour or so rather than the moment you wake, keep it to a sensible amount and stop by lunchtime. If you rely on it just to function, that's usually a sign your sleep needs attention, not that you need another cup. Energy drinks and pre-workout powders can contain a lot of caffeine, so check the label.
Screens, light and evenings
Bright light late in the evening tells your brain it's still daytime. Dim the lights an hour before bed, use night mode on your devices and, where you can, put the phone away. The content matters as much as the light: work emails and news at 10pm wind you up. Choose something calmer. And if you use your phone as an alarm, buy a cheap alarm clock and leave the phone in another room.
Shift work and irregular schedules
If you work nights, rotating shifts or on call, perfect sleep isn't always possible, but you can improve it. Treat your sleep like an appointment and protect it: blackout curtains, a quiet room, a note on the door, the phone on silent. Use bright light when you want to be alert and avoid it before sleep. Keep your meal times as regular as you can, and keep caffeine to the first half of your shift. Short naps before a night shift can help. Be extra careful driving home after a night shift, because drowsiness is dangerous. Find the recovery tips in the training guide too: a lighter week after a heavy block of shifts is sensible.
Breathing practices to try
- Long out-breath: in through your nose for four, out through your mouth for six to eight. Do five to ten rounds.
- Box breathing: in for four, hold for four, out for four, hold for four. Do it for a few minutes. It's used widely by people who need to stay calm under pressure.
- Physiological sigh: two quick breaths in through the nose, then a long breath out. Two or three rounds can take the edge off a spike of stress.
If breath-holding makes you dizzy or anxious, skip the holds and just make your out-breath longer. Stop if you feel lightheaded.
Do sleep trackers help?
For some men, yes: seeing patterns can motivate change. For others, the numbers cause more worry than the sleep problem itself. If your tracker makes you anxious, stop wearing it. How you feel in the morning is the best measure.
Questions I get asked
Is it bad to sleep in at the weekend? A small lie-in is fine. A big swing in wake-up times makes Monday harder. Keep it within an hour if you can.
Should I use melatonin or sleeping tablets? Talk to your GP or pharmacist first. In the UK, melatonin is a prescription medicine for most people. Habits come first, and medication is a decision to make with a professional.
Is cold water or an ice bath good for recovery? It may make you feel fresh, but it isn't essential and can blunt some training adaptation if you do it straight after lifting. Sleep, food and an easier week do more.
A simple morning and evening routine
Routines work because they remove decisions. Here is a plain example you can adapt.
Morning (10 to 15 minutes): get up at your set time, drink a glass of water, open the curtains, spend five minutes outside, then have breakfast with some protein. Do a few minutes of movement, such as ten squats or a short walk, before you look at your phone.
Evening (30 to 45 minutes): finish work and caffeine early, have your last big meal a couple of hours before bed, dim the lights, write your worry list and tomorrow's one priority, put the phone on charge outside the bedroom, then read or stretch. Five slow breaths in bed. Lights out.
You don't need to do all of it, every day. Start with two or three items from each list, and pin them to triggers you already have.
