How to sleep in hot weather: our six top tips

Drink plenty of water

Ever woken up with a parched throat or dry mouth? If so, it’s a sign that you haven’t drunk enough water before going to bed. As well as ensuring the body functions properly, good hydration helps you get to sleep and stay asleep. When you fail to drink enough water, you tend to take longer to fall asleep and to wake up in the night.

In practice: To get good night’s sleep, remember to drink a large glass of water before retiring for the night and keep a bottle of water by your bedside. Contrary to popular belief, you should avoid drinking fluid that’s too cold or too hot. Too great a difference between the ambient temperature and that of your water requires extra effort from the body which may make it harder to fall asleep.

Ventilate and humidify your bedroom

If staying well-hydrated is important, so too is controlling the humidity in your home during periods of hot weather. When the air is too dry, it can encourage the body to become dehydrated and affect sleep quality. Maintaining or creating a humid atmosphere can thus help you to sleep well. Don’t forget to ventilate your home regularly to renew the circulating air.

In practice: Take advantage of the early morning to ventilate your bedroom. To increase humidity, try placing a container of water in the room, or draping damp sheets at the windows. Shower before going to bed, but don’t completely dry yourself. The film of water left on your skin will maintain the refreshing effect of the shower, prevent your body temperature from rising and help you get to sleep more easily.

Choose the best time to go to sleep

We’re often advised to ‘have an early night’ if we want a longer, more restorative sleep. However, this is not necessarily the best advice during periods of hot weather. It can be better to go to bed later when the temperature has dropped as it will be easier to get to sleep and you’re less likely to keep on waking up. It’s better to have a shorter, effective sleep than a longer, interrupted sleep.

In practice: Wait until the temperature is a little cooler before going to bed. Use the free time to relax. To help you get to sleep, you could benefit from the effects of melatonin. Known as the ‘sleep hormone’, it helps regulate our biorhythms.

Stay calm and relaxed

When the weather’s hot, it’s often more difficult to get to sleep which can lead to a state of agitation. As the night progresses, we become more and more stressed and this unfortunately causes our body temperature to rise, making sleep even more elusive. To avoid this vicious circle, we therefore need to control this stress by taking active steps to relax.

In practice: To avoid becoming stressed, try some relaxation exercises or meditation. Don’t, however, engage in too intense a physical activity before going to bed. Certain anti-stress supplements, such as the neurotransmitter GABA, can also help you relax.

Take advantage of sleep-inducing plants

Plants with sedative properties have been shown to be effective even in very hot weather when sleep problems tend to be worse. The best-known of these include camomile, linden and lemon balm, though there are actually dozens of plants with sedative, calming and relaxing properties. For effective relief against heat-related sleep problems, combining a number of plants can be a good idea. For example, studies have confirmed the efficacy of a valerian/hop combination for treating occasional sleep problems.

In practice: Discover the surprising power of sedative plants. They can either be taken as infusions or as dietary supplements. Developed to both reduce the time it takes to fall asleep and improve sleep quality, the formulation Natural Sleep Formula contains several plants including valerian, hop and rhodiola.

Eat a light, healthy dinner

Who hasn’t woken up feeling tired after a heavy meal the night before? A high-calorie intake at dinner prevents the stomach from settling for several hours. By remaining active for part of the night, the body is unable to rest properly. In addition, the process of digestion tends to increase body temperature which can make it harder to fall asleep. That’s why it’s better to have a light meal at dinnertime in order to achieve good, restorative sleep.

In practice: When the weather’s hot, it’s particularly important to avoid alcohol and restrict consumption of high-calorie foods. ‘Eat light’ by prioritising foods such as fruit, vegetables, fish and white meat.
