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.

Water Delivery Within the M25: Why Choosing a Local Supplier Matters

Finding a reliable water delivery service in London can feel a little overwhelming. With so many options, it’s easy to miss one simple truth: local suppliers offer faster, more flexible, and more sustainable service than national chains ever can.

If your home or office is within the M25, here’s why choosing a London-based water delivery company makes a real difference.

Local suppliers understand London’s pace

London doesn’t move slowly — and neither should your water deliveries.
A supplier based within the M25 understands peak traffic, business hours, loading bay restrictions, and how quickly a busy office can run through 19L bottles.

A local team can plan smarter routes, avoid delays, and keep your hydration flowing without disruption.

Faster, flexible deliveries when you need them

The biggest advantage of choosing a local supplier is speed.
Instead of waiting days or relying on national delivery windows, you can expect:

  • Shorter delivery lead times
  • Flexible schedules tailored to your location
  • Easier last-minute changes
  • A driver who’s familiar with your building

It’s a service designed around your needs — not a one-size-fits-all national system.

More reliable service for offices and homes

If your office suddenly runs low on water, or your home needs top-up bottles before the weekend, a local supplier is simply closer, quicker, and easier to reach.

You get direct communication, predictable routes, and a team nearby who can respond swiftly.
It’s the kind of reliability London businesses depend on.

Supporting local businesses matters

Choosing a supplier within the M25 means supporting real people working in your community — drivers, warehouse staff, admin teams and customer service based in your area.

Your spend stays local, strengthening small and medium-sized businesses that keep London running.
And you get a service built on long-term relationships rather than call-centre scripts.

Lower carbon footprint, greener deliveries

Local delivery routes mean:

  • Shorter travel distances
  • Fewer emissions
  • Less fuel usage
  • A more efficient supply chain

It’s a simple, meaningful step towards reducing your organisation’s environmental impact — especially compared with transporting water from far outside London.

Couple that with reusable 13L and 19L bottles, and suddenly your hydration choices are significantly more sustainable.

Better communication, better customer care

A local supplier is easier to reach and quicker to respond.
When you call, you speak to someone who knows your account, your needs, your delivery history — not a national helpline.

Problems get solved faster. Questions get answered immediately.
You feel like a valued customer, not a number in a queue.

Why Drinking Water Is Just as Important in Cooler Weather

As the days start to cool and we slowly transition into autumn, it’s easy to forget about drinking water. In warmer months, thirst naturally reminds us to stay hydrated, but during cooler weather, our bodies can still become dehydrated – even if we don’t feel it.

Here are some key reasons why keeping up your water intake is crucial as the seasons shift:

1. Boost Your Immune System:

Hydration helps your body flush out toxins and keeps your immune system strong, which is especially important as cold and flu season approaches.

2. Maintain Your Energy Levels:

Even in cooler weather, staying hydrated is key to avoiding fatigue and keeping your body functioning optimally throughout the day.

3. Prevent Dry Skin:

As temperatures drop and indoor heating rises, your skin can easily become dry. Drinking water helps maintain skin hydration from within.

4. Support Overall Health:

Your body still loses water through everyday activities like breathing and exercising, regardless of the temperature outside. Staying hydrated keeps your joints lubricated, digestion smooth, and mood balanced.

To help you stay on top of hydration, especially when you’re less likely to feel thirsty, we offer convenient delivery of bottled water and water packs, as well as a range of plastic and stainless steel water coolers. You can rent from as little as £2 per week or purchase from £179, perfect for any space – whether it’s your home, office, or warehouse. A water cooler makes it easy to enjoy a refreshing glass of water anytime, keeping you healthy and hydrated, no matter the weather.

Stay energised, stay positive, and remember: drinking water isn’t just for summer!
