When temperatures rise, it's not just your motivation that melts away.

Many of us notice we feel more tired, sluggish and dehydrated during a heatwave, even if we're drinking more water than usual.

That's because your body is working much harder behind the scenes to keep you cool. You sweat more, lose more fluids, your sleep is often disrupted and your energy reserves can quickly take a hit.

The good news? A few simple changes to your daily routine can help you stay refreshed, hydrated and feeling more like yourself all summer long.

Why Does Hot Weather Make You Feel So Tired?

Your body is incredibly good at regulating temperature.

During a heatwave it increases blood flow to the skin and produces more sweat to cool you down. While this is essential, it also means your body is using more energy than usual.

Common effects of prolonged hot weather include:

• Feeling unusually tired throughout the day
• Poor concentration and brain fog
• Increased thirst
• Reduced appetite
• Difficulty sleeping
• Feeling generally run down

If you're spending time outdoors, exercising or travelling, these effects can become even more noticeable.

Hydration Is About More Than Just Drinking Water

Water is essential but hydration isn't simply about how much you drink.

During hot weather you're constantly losing fluid through sweat, even if you don't realise it.

To stay properly hydrated:

• Drink little and often throughout the day
• Eat water-rich foods like watermelon, cucumber, strawberries and oranges
• Limit excess alcohol, which can contribute to dehydration
• Keep a reusable water bottle nearby
• Start your morning with a large glass of water before coffee

Small habits make a big difference.

Heatwaves Can Increase Your Nutrient Needs

Sweating doesn't just mean losing water.

Hot weather can place extra demands on your body, meaning maintaining a healthy intake of vitamins and minerals becomes even more important.

A balanced diet remains the foundation of good health, but many people find a daily multivitamin helps support their nutritional intake, particularly during busy periods, travel or times when eating habits become less consistent.

Frequently Asked Questions

Does hot weather make you more tired?

Yes. During a heatwave your body works harder to regulate temperature through sweating and increased blood flow, which can leave you feeling more fatigued than usual.

Is drinking water enough during a heatwave?

Water is essential, but hydration also depends on replacing fluids consistently and eating a balanced diet that provides essential nutrients. During periods of heavy sweating, electrolytes can also become important.

Can vitamins help with summer fatigue?

If you're not meeting your nutritional needs through diet alone, a daily multivitamin can help support normal energy-yielding metabolism and contribute to the reduction of tiredness and fatigue through nutrients such as B vitamins and vitamin C.

Why choose effervescent vitamins?

Effervescent vitamins are easy to take, refreshing during warm weather and provide a convenient way to support your daily nutrient intake.
