Why summer can be the perfect storm for poor sleep

If you've spent the past few nights kicking off the covers, turning the pillow over and staring at the ceiling at 3am, you're not alone.

When temperatures rise, sleep often suffers. But while the heat is certainly part of the problem, it isn't always the whole story.

For many women in midlife, summer can create the perfect storm for poor sleep. Hot weather, hormonal changes, blood sugar fluctuations, alcohol and disrupted routines can all combine to make a good night's sleep feel frustratingly out of reach.

Let's take a closer look at what's going on.

Your body needs to cool down to sleep

One of the body's natural sleep signals is a drop in core temperature. In hot weather, that process becomes more difficult.

If your body can't cool down efficiently, falling asleep and staying asleep can become much harder. That's why even people who usually sleep well may find themselves tossing and turning during a heatwave.

Midlife hormones can add to the challenge

During perimenopause and menopause, declining oestrogen can affect the body's ability to regulate temperature, making many women more sensitive to heat. Hot flushes and night sweats can add to the problem, but even women without these symptoms often find they feel warmer at night than they once did. As a result, hot weather can have a bigger impact on sleep during midlife.

Don't forget blood sugar

The heat isn't always the reason you're awake at 3am.

If blood sugar drops overnight, the body releases adrenaline and cortisol to bring it back up. These stress hormones can jolt you awake and make it difficult to get back to sleep.

This can be particularly problematic if your evening meal was heavily based on refined

carbohydrates, if you skipped dinner, or if alcohol was involved.

In some cases, the heat is simply exposing an underlying blood sugar issue.

Summer often means more alcohol

Whether it's a glass of rosé in the garden, a barbecue with friends or a holiday abroad, alcohol often makes a more frequent appearance during the summer months.

Although alcohol can make you feel sleepy initially, it tends to reduce sleep quality later in the night. It can increase night-time waking, worsen hot flushes, contribute to dehydration and make blood sugar levels less stable overnight.

Combined with hot weather, the effect can be significant. That doesn't mean you can't enjoy a drink, but if sleep has gone off track, alcohol is often worth considering as part of the picture.

Stress doesn't take a summer holiday

Many people assume summer should be relaxing, but that isn't always the case.

School holidays, travel plans, disrupted routines, family commitments and trying to juggle work around it all can create even more stress.

When we're stressed, the body produces more cortisol. While cortisol plays an important role in helping us cope with challenges, elevated levels can make it harder to switch off, fall asleep and stay asleep by keeping us in a state of alertness.

For some people, summer can become the perfect storm of heat, disrupted routines and elevated stress, all working against a good night's sleep.

What can you do?

The good news is that a few simple changes can make a difference.

Keep your bedroom as cool as possible. Close curtains or blinds during the day to block out heat and open windows once the temperature drops outside. If you have a fan, placing a bowl of ice or a frozen water bottle in front of it can create a cooling effect.

Keep bedding light. Natural fibres such as cotton and linen tend to be cooler and more breathable than synthetic fabrics. A cool pack wrapped in a tea towel or chilled pillowcase can also provide temporary relief on particularly hot nights.

Take a lukewarm shower before bed. It may seem counterintuitive, but very cold showers can cause the body to generate heat afterwards. A lukewarm shower can help your body lose heat more effectively.

Stay hydrated throughout the day. Dehydration can worsen fatigue, headaches and sleep disruption. Aim to drink regularly during the day rather than trying to catch up in the evening.

Be mindful of alcohol. While a drink may help you feel sleepy initially, it can increase night-time waking, worsen hot flushes and contribute to dehydration.

Think about blood sugar. A balanced evening meal containing protein, healthy fats and fibre can help support stable blood sugar levels overnight. Try to avoid relying on sugary snacks or alcohol as a late-evening treat. If you're hungry before bed, try a small snack that combines protein and healthy fats, such as Greek yoghurt with nuts or oatcakes with nut butter.

Consider additional support. Some people find supplements such as magnesium glycinate or tart cherry concentrate helpful as part of a broader sleep routine.

Magnesium plays a role in nervous system function and relaxation, while tart cherries naturally contain compounds that may support melatonin production. They won't overcome a hot bedroom or poor sleep habits, but they may be useful additions for some people.

Give yourself time to unwind. Summer schedules can be hectic. A short walk, some gentle stretching, reading or a few minutes of slow breathing can help signal to your body that it's time to switch off.

Sleep is rarely about one thing. While the heat may be the trigger, poor sleep is often the result of several factors working together.

The bottom line

If you're struggling to sleep this summer, don't assume the weather is entirely to blame.

For many women in midlife, hot weather can magnify existing issues with hormones, blood sugar balance, stress and lifestyle habits.

The good news is that addressing these underlying factors won't just help you through the next heatwave. Better sleep

can have a positive impact on your energy, mood and overall wellbeing all year round.
