UK Heatwave Sleeping Arrangements: Why Hot Nights Affect Your Sleep
With the UK seeing an increase in longer and more frequent hot days, hot nights can negatively impact your quality of sleep, despite the fact that many people welcome these sunny days. A lot of the UK is built to retain heat, meaning bedrooms will be hot well into the night when the sun has gone down, unlike other countries where homes are built for extremely hot weather, making your chances of getting a good night’s sleep much lower.
With the increased importance of how to sleep in hot summer nights, it’s also important to understand what heat does to your sleep and how to identify if your bedroom is too warm, as well as what can be done to prepare your house before the temperatures increase.
Why heatwaves are becoming more common in the UK
The increased frequency and intensity of summer heatwaves in the UK in recent years has brought a number of challenges, including frequently experiencing very warm daytime temperatures that are then followed by increasingly warm night-time temperatures, creating an uncomfortable environment to sleep indoors due to improper cooling of your home. Consequently, many people find it difficult to fall asleep, awaken multiple times during the night, or wake up feeling worn out.
Preparing for extreme heat is now a necessary safety measure and important consideration for those staying at home or travelling in a caravan or camping during the summer.
How high nighttime temperatures disrupt your sleep cycle
Before you head off to sleep, your body lowers its temperature naturally in preparation for falling asleep. If your room is above 18–20°C (64–68°F), your body has a difficult time getting cool so that you can fall asleep. Due to a warm bedroom, you could experience the following:
Trouble starting your sleep cycle
Awaken during the night often
Possibly not having as much deep or REM sleep
Sweating more and feeling dehydrated
Waking up tired and not as productive in the morning
If you cannot cool down your sleeping environment during extended heat waves, you will see these interruptions while you are trying to sleep.
Signs your bedroom is too hot for quality sleep
Most people are unaware of how much influence the thermal condition of their sleeping environment has on how deeply they sleep and hence how tired they feel when they wake up.
Common symptoms include:
Continuous movement throughout the night
Dawn dampness from perspiration from sleeping
Dampness on bedding or pillows
Feeling exhausted even though you should have been able to sleep well due to long hours.
Headaches and/or fatigue after waking up.
Looking for a cooler location consistently to be able to fall asleep.
If you notice these symptoms, then it could be an indication that your sleeping environment is not conducive to restful sleep.
Preparing your home before a heatwave arrives
A little preparation before a heat wave can really help when the hot weather arrives. Close the curtains or use blackout blinds to block the sun during the hottest time of day. Open the windows at night when it is cooler to let cool air into your home. Use cotton sheets as they are breathable and do not hold the heat. Turn off any lights or appliances that are not needed. These easy steps will help you to lower the temperatures inside your house and create a better place to sleep.
For individuals who will be spending time outdoors camping, or for those who may be affected by a summer power outage, planning ahead with a good portable air conditioning unit and having access to backup power are also great ways to help keep you comfortable, especially when dealing with extreme heat.
With an understanding of why hot summer nights can disrupt sleep, it’s time to look at some simple steps to take. These next 15 sleep solutions have been compiled from professionals who provide ways to keep cool, improve sleep quality and make the hottest summer nights in the UK bearable while at home and out on the trails.
How to Sleep in Hot Summer Nights: 15 Expert Tips That Actually Work
If you have ever had difficulty sleeping because of the heat on a summer night, you will find that you are not alone. One of the hardest things to do during those summer months is to find a way to sleep on the hottest summer nights without waking up all night long from being hot.
With some small changes to your sleeping environment, as well as your bedding, and your pre-sleep routine, you will be able to improve your comfort and sleep quality.
The following tips have been developed by experts, and are easy and inexpensive to implement in an effort to help keep you cool and allow for better quality sleep during the hottest summer months in the UK.
Creating a Cooler Sleeping Environment
A room should be conducive to sleeping. The room should be a cool, calm, and relaxing place to help your body prepare for sleep. Since our body temperature decreases prior to sleep onset, lowering the temperature of your room prior to sleep should increase the quality of your sleep.
Keep your bedroom below the ideal sleep temperature
Most sleeping specialists suggest temperate rooms of 60°F–67°F, or 16–19°C, when you are trying to sleep. If you are attempting to get pregnant in a UK heatwave, it can be challenging to obtain that temperature, but by reducing the temperature of your bedroom by just a few degrees, you can help your body to fall asleep more quickly and stay asleep longer.
When your house starts getting too hot at night or when you are camping in a tent or campervan, portable cooling is a great option to keep you comfortable. Air conditioners run through a reliable power device can provide an excellent source of comfort whether you are at home or away from home.
Block daytime heat with curtains and blinds
One of the simplest ways to reduce the amount of heat that enters your bedroom is to block it out in the first place. Close your curtains, blackout blinds or reflective window coverings during the hottest part of the day. When you do this, you will reduce the heat gained by solar radiation and retain a cooler indoor temperature before you go to sleep.
Improve natural ventilation and airflow
You can quickly cool your bedroom as soon as the outdoor temperatures start to go down by allowing fresh air into the room at night hours or in the early morning by opening the windows and positioning fans correctly for cross ventilation purposes.
Proper airflow will allow you to remove excess heat from the room and create a more comfortable sleeping environment.
Choose the Right Bedding and Clothing
Most individuals do not appreciate how crucial your bedding and sleepwear are in helping to help your body sleep throughout the night. Heavyweight fabrics maintain body heat whereas breathable fabrics allow the body to use its own natural system to control the temperature of your body while sleeping.
Switch to breathable cotton or bamboo bedding
Bamboo and cotton are organic materials that allow the body to eliminate body heat and humidity much better than artificial materials do. In addition to being lightweight, having lighter weight sheets can not only keep you comfortable during the night, but they can also assist in reducing the amount of perspiration you experience while sleeping.
Wear lightweight sleepwear
Loose-fitting cotton or moisture-wicking sleepwear will let your skin breathe better, keeping you cooler by allowing air to flow freely around your body. If you're experiencing extreme heat, consider wearing fewer clothing items when going to bed.
Try cooling pillows and mattress toppers
Cooling pillows and gel-infused mattress toppers are designed to keep you cooler, while also providing support. These types of items can be extremely beneficial during those hot summer months as most mattresses will typically retain heat due to their construction.
Healthy Bedtime Habits for Better Sleep
Evenings are equally essential to create healthy habits and cool down your sleeping quarters (your bedroom). You can also make several lifestyle changes that can assist your body in adapting better to warmer weather and sleep more soundly.
Stay hydrated throughout the day
Drink enough to stay hydrated throughout the day, so that you restore the fluids you lose during the day from perspiration. Being properly hydrated also helps your body's cooling system. However, try not to drink too much shortly before going to bed so that you will not need to get up during the night to use the restroom.
Eat lighter evening meals
Eating heavy or spicy food elevates your metabolism, creating additional body heat while you are trying to sleep. Opt for lighter meals consisting of fresh veggies, fruits, and lean proteins for a better feeling during hot summer nights.
Take a cool shower before bed
Getting in a cool or lukewarm shower will help lower your body temperature and remove sweat, so you can feel refreshed before going to bed. Do not use really cold water as it will cause your body to create more heat later.
Avoid alcohol, caffeine, and screen time
Alcohol and caffeine both negatively affect sleep quality and both add to dehydration in hot weather. Screen time on your phone, table or television has a higher concentration of blue light compared to screen time on a computer, will delay melatonin production, which means it will take longer for you to fall asleep.
Freeze a hot water bottle for instant cooling
An alternative way to use a hot water bottle, as opposed to filling it up with hot water, would be to freeze it instead for a few hours. Then wrap the frozen bottle in a towel and use it as a cool compress on your feet or legs without making your bed damp.
Sleep on the lowest floor of your home
As heat rises, ground-level rooms and basement areas of your home will typically stay a few degrees cooler than the upper floor of your house. If you can, consider temporarily relocating your sleeping area for the duration of extreme heat.
Know when it's unsafe to sleep in extreme heat
If you are still experiencing abnormally high room temperature despite taking appropriate measures to cool it down, watch for symptoms of possible heat exhaustion, including but not limited to dizziness, confusion or rapid heart rate, nausea, and excessive sweating. If you experience any of these symptoms, take immediate action to cool off. Heat exhaustion is a medical emergency and requires immediate medical attention.
Use Portable Cooling During Power Outages or Outdoor Stays
During the summer months, heatwaves sometimes happen at the same time as power supply outages or while enjoying an outdoor adventure without any way of cooling down.
Whether enjoying a camping experience, caravan holiday, or spending time in your garden room, if you have a reliable portable power source, you can stay cool and comfortable all night long by using a portable air conditioner. This is a great way to ensure you get a good night's sleep away from your home or in a remote area.
Create a Relaxing Bedtime Routine
Calming activities like reading books, stretching lightly, meditating, or listening to soft music will provide an understanding to your body that it is time to sleep. Having a consistent bedtime routine will assist you in getting to sleep easier on hot nights.
Best Sleeping Arrangement for Camping During a Heatwave
Camping is the best way to relish Uk summers. However, sleeping within a tent during a hot spell would swiftly transform your camping trip from an adventure to an uncomfortable one. With UK temperatures continuing to rise, determining the ideal sleeping solution for camping isn't solely about comfort; it's also about keeping cool, being able to rest, and ensuring your safety and security.
No matter if you're out in the hills or camping as part of a family glamping, going to a music festival or on a road trip in a campervan, there are some simple changes you can make that will give you not only a cooler night's sleep but also a more restful night's sleep while camping or glamping.
Stay Cool While Camping, Glamping, or Travelling
Choose the coolest campsite location
Avoid camping in wide open, un-shaded areas that are exposed to the direct afternoon sun as they act as heat sinks, and therefore will still have heat present once the sun has set.
Position your tent for maximum shade
Choose a location for your tent that will have shade over it during the hottest part of the day . You may also want to use a reflective tarp or canopy to further reduce the amount of heat trapped inside the tent itself.
Improve tent ventilation during hot nights
When safe to do so, open the mesh windows, roof vents, and doors of your tent for maximum ventilation; when there is good ventilation in your tent, hot air will escape, while cooling evening air will be able to move through it.
Choose the best sleeping arrangement for camping in warm weather
When camping during the summer, use a lightweight sleeping bag or cotton sheet; use a ventilated sleeping pad/cot and wear moisture-wicking sleepwear to ensure you are able to maintain a comfortable temperature while sleeping during the night.
Portable Cooling Solutions for Outdoor Adventures
While air movement is increased by portable fans, they are not ideal for providing adequate room cooling. Instead, fans simply rotate air in a room and only help provide heat relief on hot summer evenings.
