Beat the Heat: 8+1 Simple Ways to Keep Your Home or Office Cool Without Air Conditioning

When a heatwave arrives, keeping your home or workplace comfortable can be difficult—especially if you don’t have air conditioning.

Fortunately, there are plenty of simple ways to reduce indoor temperatures naturally. From blocking out the sun to staying properly hydrated, these practical tips can help you stay comfortable while using less energy.

Here are our favourite ways to beat the heat.


1. Keep the Sun Out

One of the easiest ways to keep your home cooler is to prevent the sun’s heat from entering in the first place.

Close blinds or curtains on windows that receive direct sunlight, particularly south- and west-facing windows.

Did you know? Up to 30% of unwanted heat can enter through your windows. Keeping blinds closed during the hottest part of the day helps reduce indoor temperatures naturally.


2. Open Windows at the Right Time

It might seem logical to keep your windows open all day, but this can actually make your home warmer.

When the air outside is hotter than indoors, keep windows and doors closed.

Instead, open them:

  • Early in the morning
  • Late in the evening
  • Overnight (when safe)

This allows cooler air to circulate through your home before temperatures rise.

❌ Myth: Opening windows all day keeps your house cool.
✅ Fact: During the hottest hours, you’re often letting hot air inside. Ventilating early in the morning and overnight is much more effective.


3. Help Your Fan Work More Efficiently

A fan doesn’t actually cool the air—it cools you by increasing the evaporation of sweat from your skin.

To make it even more effective:

  • Place a bowl of ice or frozen water bottles in front of the fan.
  • Lightly dampen hard floors with cold water before using the fan nearby.

As the water evaporates, it absorbs heat from the surrounding air—a process called evaporative cooling.


4. Wear Breathable Clothing

What you wear makes a big difference during hot weather.

Choose loose-fitting clothing made from natural fibres such as:

  • Cotton
  • Linen
  • Bamboo

These materials allow air to circulate and absorb moisture, helping you stay cooler.

Synthetic fabrics like polyester tend to trap heat and moisture, making hot days feel even warmer.


5. Eat Foods That Help You Stay Hydrated

Many fruits and vegetables contain a high percentage of water, making them perfect for hot weather.

Some great choices include:

  • Watermelon
  • Cucumber
  • Strawberries
  • Oranges
  • Lettuce

Top tip: Add slices of lemon, lime, cucumber, strawberries or fresh mint to your water. It’s a refreshing 2-in-1 that helps you enjoy more fruit while drinking more water.


6. Reduce Indoor Heat

Many everyday appliances generate unnecessary heat.

Try to:

  • Use the microwave, air fryer or BBQ instead of the oven.
  • Turn off electronics when they’re not being used.
  • Switch to LED lighting.
  • Dry washing outside whenever possible.

Small changes can have a noticeable impact on indoor comfort.


7. Cool Yourself Down

Sometimes it’s easier to cool yourself than the whole room.

Simple ideas include:

  • Taking a cool (not icy) shower.
  • Using a cool, damp towel on your neck or wrists.
  • Chilling your pillowcase before bed.
  • Using a frozen hot water bottle or cooling pack wrapped in a towel.

These quick tricks can make hot days—and especially warm nights—much more comfortable.


8. Stay Hydrated

Your body is around 60% water, and it relies on that water to regulate its temperature.

Even mild dehydration can make hot weather feel much more uncomfortable.

Did you know? Losing just 1–2% of your body water can reduce concentration, increase fatigue and affect physical performance.

Rather than waiting until you’re thirsty, sip water regularly throughout the day.


💙 One Last Tip

One of the easiest ways to drink more water is simply to make it convenient.

Whether you’re working from home, in the office or spending time with family, having fresh chilled water available encourages everyone to stay hydrated.

A water cooler provides instant access to refreshing spring water throughout the day, helping you build healthy hydration habits without constantly filling kettles or buying bottled drinks.

At London Water Delivery, we supply reliable water coolers and fresh spring water to homes and businesses across London, with free delivery within the M25.

If you’re thinking about adding a water cooler or simply need to top up your next water delivery, we’d be delighted to help.


Stay cool, stay hydrated and enjoy the sunshine! ☀️

🎁 Festive Hydration Tips: Stay Merry, Bright & Hydrated This December

The countdown is officially on — just one month until Christmas! December sneaks up fast with busy days, late nights, office parties, family gatherings, and endless to-do lists. And while we’re all wrapped up in the festive whirlwind, one thing is ridiculously easy to forget: drinking enough water.

Hydration isn’t exactly the star of Christmas… but it quietly keeps everything running smoothly. Better energy, better skin, better sleep, better immune support — all pretty handy during the busiest time of the year.

So before things get extra merry, here are a few simple and genuinely helpful Festive Hydration Tips to keep you feeling your best this season.

1. Start Your Day with a Glass of Water

The morning coffee is sacred, we get it — but drinking a glass of water before your caffeine gives your body a head start. It helps wake you up naturally and rehydrates you after a night’s sleep (or after last night’s Christmas party 🍷).

2. Keep a Bottle Within Arm’s Reach

Whether you’re working from home, running a busy office, or prepping for guests, having water in sight makes you much more likely to drink it.
A reusable bottle or a cooler nearby turns “I should drink water” into “Oh, here it is.”

Bonus: it’s one less thing to think about when life gets busy.

3. Sip Smart Between Festive Drinks

Wine, bubbly, cocktails, mulled wine… December is basically hydration chaos.
A simple trick?

👉 Have one glass of water between every alcoholic drink.

It keeps you refreshed, slows the sugar crash, and helps avoid that “why did I do this” feeling the next day.

4. Give Your Water a Christmas Makeover

If plain water doesn’t spark joy, make it festive:

  • Orange slices + cinnamon stick
  • Cranberries + rosemary sprig
  • Lemon + mint
  • Frozen berries as “edible ice cubes”

It looks gorgeous on the table and makes everyone more likely to drink.

5. Hydrate While You Host

When you’re cooking, decorating, or running around sorting presents, you can go hours without realising you haven’t had a sip.

Try this: each time you go back to the kitchen, drink four big sips of water.
Easy. Simple. Weirdly effective.

6. Add Water to the Table Spread

We always make space for the chocolates, cheese boards and Christmas pud… but water deserves a spot too.

A jug of fresh water at the table (maybe with lemon or herbs) is a small touch that encourages everyone to stay hydrated — especially after salty party food.

7. Don’t Wait Until You’re Thirsty

Thirst is your body’s late alarm.
During winter, cold weather makes us less likely to feel thirsty, even when we need water.

So aim for steady sipping throughout the day. Tiny habits → big difference.

8. Stock Up Before the Holiday Rush

If you rely on bottled water deliveries for home or office hydration, December is the best time to top up.
The last thing you want is to run out just as everything closes for Christmas.

Make sure you’re stocked with enough bottles to carry you through the festive break — future you will thank you.

🎄 Stay Merry, Bright… and Hydrated

Christmas is more fun when you feel good, and staying hydrated is one of the simplest ways to keep your energy up through all the celebrations.

Here’s to a healthy, happy, and beautifully hydrated festive season! 💧✨

If you need to top up your water before the Christmas rush, we’re here to help — just place your order ahead of time so you’re fully stocked for the holidays.

World Kindness Day: Kindness Starts with Hydration

Every year on 13 November, people around the world celebrate World Kindness Day — a reminder that even the smallest gestures can make a big difference.
At London Water Delivery, we believe kindness starts with looking after ourselves and those around us — and that includes staying hydrated!

💧 Why Hydration is an Act of Kindness

When we’re well-hydrated, we’re not only healthier and more focused — we’re also kinder.
Drinking enough water boosts mood, reduces fatigue, and helps us stay patient and positive throughout the day.

So next time you fill your glass, think of it as a small act of self-care — and maybe offer to refill someone else’s too!

🫶 The Kindness Challenge

To mark World Kindness Day, we’re inviting everyone to take part in our Kindness Challenge:

📌 Step 1: Write a small note — “Kindness Challenge: Drink More Water 💧”
📌 Step 2: Stick it somewhere visible (your desk, the office cooler, or kitchen).
📌 Step 3: Remind a friend, colleague or family member to take a sip!

You might be surprised how much a tiny act like this can brighten someone’s day.

🌍 Kindness Every Day

Of course, kindness isn’t only for one day a year. Whether it’s checking in on a teammate, holding the door, or topping up the office cooler before it’s empty — every thoughtful action counts.

At London Water Delivery, we’re proud to support healthy, hydrated workplaces and homes across London. Because keeping others refreshed is just another way of spreading a little kindness.

💧 Join Us!

This World Kindness Day, take a moment to:
✨ Drink more water
✨ Be kind to yourself and others
Tag someone to join the challenge

Together, let’s make London a little more hydrated — and a lot more kind 💛

How Many Litres of Water Does an Office Need per Person per Week?

Keeping your team hydrated is one of the simplest ways to boost wellbeing and productivity at work. But when it comes to ordering water for your office, it can be tricky to know how much is actually needed. Too little, and you’ll run out midweek. Too much, and bottles sit unused.

Here’s a quick, practical guide to help you work out how many litres of water your office needs per person per week, plus a few smart ordering tips from our delivery team.

💧 How Much Water Does One Person Need a Day?

According to the NHS, adults should drink around 6–8 glasses of fluids a day — roughly 1.5 to 2 litres.
At work, most people get about half of their daily hydration there, especially during office hours.

That means the average person drinks about 1 litre of water per working day, or roughly:
➡️ 5 litres per person per week (based on a standard 5-day working week).

Simple Office Water Calculation

Number of EmployeesLitres per Week (approx.)Equivalent in 18.9L Bottles
5 employees25 L1–2 bottles
10 employees50 L3 bottles
20 employees100 L5–6 bottles
50 employees250 L13 bottles
100 employees500 L26 bottles

💡 Tip: Always round up slightly to allow for visitors, meetings, and warmer weather — hydration needs rise in summer or in air-conditioned offices.

Factors That Affect Water Usage

Every workplace is different, so it’s best to consider a few key factors:

  • Work environment: Offices with physical activity (e.g. warehouses or studios) use more water than desk-based teams.
  • Season: Expect a 20–30% increase in summer.
  • Office size and culture: Teams that encourage healthy habits and regular breaks tend to drink more water.
  • Meetings and guests: Client visits, training sessions, or events add extra consumption.
  • Events & catering: Keep a few smaller bottles handy for conferences, away days, or special occasions.
