Sleep Well During Heatwaves: Tips for Restful Nights

Hot weather can make sleep difficult, but even a few small changes can make a noticeable difference.

If your bedroom has felt impossible to sleep in recently, you’re not alone. UK homes are designed to keep heat in — which is great in winter, but not so great during a heatwave.

When temperatures stay high overnight, falling asleep can feel frustrating, uncomfortable, and exhausting. The problem is that your body needs to cool down slightly before you can properly drift off to sleep. When your room is too warm, that process becomes much harder.

You may struggle to fall asleep, wake more often during the night, and feel tired and irritable the next day.

For businesses, this matters too. Poor sleep affects concentration, decision-making, productivity, mood, and energy levels. Even a few nights of disrupted sleep across a workforce can impact performance and wellbeing.

The good news is that there are plenty of practical things you can do to improve sleep during hot weather, from quick, free changes to longer-term solutions.

Why Hot Weather Disrupts Sleep

Your body naturally lowers its temperature in the evening to prepare for sleep. A hot bedroom makes this difficult, leaving you feeling restless and uncomfortable.

Common signs of heat-related sleep disruption include:

• Taking longer to fall asleep

• Waking during the night

• Feeling tired despite spending enough time in bed

• Poor concentration and low energy the next day

• Feeling more irritable or stressed

  
  

When sleep suffers, work performance often does too. Tired employees are more likely to make mistakes, lose focus, and struggle with problem-solving or communication.

Simple Things That Can Help Tonight

Keep Sunlight Out During the Day

Close curtains, blinds, and windows during the hottest part of the day to stop heat building up indoors. Later in the evening, open windows on opposite sides of the house to create a cooler cross-breeze.

Switch to Lighter Bedding

Heavy duvets trap heat. A light cotton sheet or breathable bedding made from natural fibres can feel much cooler.

Take a Lukewarm Shower Before Bed

A cool or lukewarm shower/bath about an hour before bed can help lower body temperature and make it easier to fall asleep.

Wear Loose, Breathable Clothing

Cotton sleepwear, or lighter layers in general, helps your body release heat more easily.

Use a Cool Cloth on Pulse Points

A cold flannel on your neck, wrists, or ankles can provide quick relief when you feel overheated.

Sleep in the Coolest Room Possible

Heat rises, so downstairs rooms are often cooler during very warm nights.

Avoid Alcohol Late in the Evening

Although a cold drink can feel refreshing, alcohol can disrupt sleep and make dehydration worse.

Reduce Caffeine Later in the Day

Caffeine can stay in your system longer than most people realise and make it harder to switch off at night.

Try Relaxation or Breathing Exercises

Fighting the heat often creates more frustration and tension. Relaxation techniques can help calm the mind and body before sleep.

If You Want (Need) a Bigger Fix

If hot weather regularly affects your sleep, a few longer-term changes may be worth considering:

• Electric fans can improve airflow and make rooms feel cooler.

• Blackout curtains help stop rooms heating up during the day.

• Cooling pillows and breathable mattress toppers can reduce overheating at night.

• Portable air conditioning units are effective for bedrooms during extreme heat.

• Smart climate controls can help maintain a more comfortable sleep environment overnight.
