Why You're So Tired This Summer (And It's Not Just the Heat)

If you've spent the last few weeks feeling like you're wading through treacle just to get through the day, you're not imagining it, and you're definitely not alone. Every summer, the same conversation happens in group chats and over iced coffees across Dubai: "I'm exhausted and I don't even know why."

Between the heat, the humidity, the disrupted sleep and the general chaos of summer schedules, our bodies are working a lot harder than we give them credit for. Here's what's actually going on, and what genuinely helps.

Your body is working overtime just to keep cool

Even if you're dashing from air-conditioned car to air-conditioned mall, your body is still contending with extreme temperature swings all day. That constant adjusting, sweating, cooling, warming back up again, burns energy. Add in humidity, which makes sweat less effective at cooling you down, and you've got a recipe for fatigue that has nothing to do with how much sleep you got.

Dehydration is sneakier than you think

By the time you feel thirsty, you're already mildly dehydrated, and even mild dehydration can cause headaches, brain fog and that heavy, sluggish feeling. In summer, women in the UAE lose fluids faster than they realise, especially if you're exercising, breastfeeding, or simply spending time outdoors. Electrolytes matter here as much as plain water does. If you're only reaching for water, you might be missing the sodium, potassium and magnesium your body needs to actually hold onto that hydration.

Hormones don't take a summer break

For many women, heat can amplify hormonal symptoms, think heavier fatigue around your cycle, worsened hot flushes if you're perimenopausal, or more intense PMS. This isn't in your head. Higher temperatures can affect how your body regulates cortisol and other hormones, which is part of why so many of us feel more emotionally frayed in July and August. If you've noticed your usual coping strategies feel less effective right now, that's worth being gentle with yourself about, not another thing to feel guilty over.

Sleep quality drops even when quantity doesn't

You might be getting your eight hours, but summer sleep is often lighter and more broken. Bedrooms run warmer, even with air conditioning working hard, and our bodies naturally sleep best when core temperature drops slightly at night. If the room isn't cool enough, you cycle through less deep, restorative sleep, and wake up feeling like you barely slept at all.

So what actually helps?

Start with electrolytes, not just water. A pinch of salt and squeeze of lemon in water, or a proper electrolyte sachet, can make a noticeable difference within a day or two. Keep your bedroom as cool as you can manage, even a few degrees lower makes a real difference to sleep quality, and consider a fan alongside the AC to help circulate cooler air.

Don't skip meals because it's too hot to think about food. Low blood sugar compounds heat fatigue fast. Light, protein-rich meals, think grilled chicken salads, labneh with fruit, or a proper smoothie, keep energy steadier than skipping meals or living on iced coffee alone.

Move your body earlier or later in the day if you can, even a 20-minute walk before 8am or after 7pm counts, and don't feel guilty about resting more than usual. Summer in this climate is genuinely more demanding on the body, and honouring that isn't laziness, it's common sense.

Finally, if the fatigue feels disproportionate, if it's paired with dizziness, an unusually fast heartbeat, or symptoms that don't ease up with better hydration and rest, it's worth getting bloods checked. Thyroid issues, iron deficiency and vitamin D levels (yes, even here) can all masquerade as "just the heat."

You're not weak, and you're not doing summer wrong. Your body is adapting to genuinely tough conditions, and a little extra kindness towards yourself this season goes a long way.
