How to maintain your energy levels in summer

Summer should feel energising — long days, sunshine, holidays. So why do so many people feel tired in July and August? The answer is that heat puts the body under low-level continuous stress, sleep gets disrupted by warmth, and the routines that usually keep us steady get thrown off by holidays and social plans. The fix isn't one big change; it's several small ones that add up.

1. Why summer is genuinely tiring
2. Sleep first, everything else second
3. Hydration done properly
4. Use daylight, don't fight it
5. Move at the right times
6. Light, frequent meals

Why summer is genuinely tiring

Heat alone uses energy — your body works harder to cool itself. Add disrupted sleep from warm bedrooms, more social plans, alcohol at barbecues and longer days that mess with bedtime, and you end up with chronic mild fatigue. It's not laziness — it's biology.

Sleep first, everything else second

If you only fix one thing this summer, fix your sleep. The cumulative effect of poor sleep across a hot week is bigger than any energy-drink boost or supplement can overcome. The keys:

• Cool, dark bedroom — see our temperature guide
• Breathable bedding — bamboo is genuinely the best option for hot nights
• Consistent bedtime, even when it's still light outside
• Block out morning light if you wake at 4am — proper blackout curtains, not just thin ones

Hydration done properly

The advice drink lots of water is right but oversimplified. Better: drink steadily across the day, not in big bursts. Stop heavy drinking 90 minutes before bed (it just means waking up to use the loo). Add a pinch of salt or some electrolyte powder if you sweat a lot during the day — water alone doesn't replace what you lose.

Use daylight, don't fight it

Get sunlight in the morning — even 10–15 minutes helps regulate your body clock. In the late evening, dim the lights and let your brain register that night is coming. Working in a brightly-lit office until 10pm and wondering why you can't sleep at 11 is a common pattern.

Move at the right times

Avoid intense workouts in the heat of the afternoon. Early morning or evening are kinder to your body. A 20-minute walk after dinner, when temperatures drop, is one of the most underrated summer habits — it aids digestion, lowers stress, and helps you sleep.

Skip vigorous exercise in the 3 hours before bed — adrenaline is still elevated and disrupts sleep onset.

Light, frequent meals

Heavy meals require energy to digest, and that energy comes from somewhere. In summer, opt for lighter meals more frequently: salads, fruit, lean protein, less carb-heavy dinners. Save the rich foods for cooler evenings. Your sleep — and your energy the next day — will be better for it.

Energy in summer isn't about pushing harder. It's about not letting heat, dehydration and disrupted sleep quietly drain you. Get the basics right and August feels like June.
