Many people find their sleep disrupted during the summer months. There are several factors that can contribute to this, including longer days, excessive sunlight, and higher temperatures. These factors can affect our hormones, particularly melatonin, which is crucial for regulating sleep. Additionally, our lifestyle choices, such as increased social activities, increased screen time, and alcohol consumption, can also impact our sleep patterns. Creating a healthy sleep environment, exercising, and managing our exposure to light and temperature can help improve sleep quality during the summer.

What You'll Learn
Light exposure and hormone production
Light exposure plays a pivotal role in regulating sleep patterns and hormone production. Light and darkness act as key factors in determining sleep, with exposure to light stimulating the region of the brain that regulates hormones such as melatonin and body temperature. Melatonin, often referred to as the "sleep hormone," increases sleepiness, with its levels rising as the sun sets and staying elevated for approximately 12 hours.
During summer, most regions experience an increase in daylight hours, resulting in longer days and excessive sunlight. This abundance of natural light impacts our hormones, including melatonin production. Sunlight entering our eyes triggers our brains to stay awake, delaying the natural rise in melatonin levels that signal the brain it's time to sleep. As a result, our bodies may not feel ready for sleep until later in the evening or even into the night, disrupting our natural sleep pattern, known as the circadian rhythm.
To counter this effect, creating an artificial nighttime environment can be beneficial. This can be achieved by using blackout curtains or blinds to eliminate external light, turning off or unplugging electronic devices, and wearing sunglasses that block out sunlight, especially if outdoor activities during the day are necessary. Additionally, exposure to morning sunlight may help regulate melatonin levels, making it easier to fall asleep at night.
Apart from natural light, artificial light from electronic devices like phones, tablets, and televisions can also disrupt our sleep. The blue wavelength of light emitted by these devices is particularly stimulating to our brains for melatonin regulation, making it harder to feel sleepy. Therefore, limiting exposure to electronic devices at least one hour before bedtime is recommended.
In summary, light exposure significantly influences hormone production and sleep patterns. During summer, the abundance of natural light can delay melatonin production, impacting our sleep. Creating artificial nighttime environments, seeking morning sunlight, and limiting screen time can help mitigate these effects and promote better sleep during the longer, lighter summer days.

Warmer temperatures
Our core body temperature decreases by a few degrees when we initiate sleep. As the temperature of the surrounding air drops, so does our core temperature, making it easier to fall and stay asleep. The ideal temperature for sleeping is around 65 degrees Fahrenheit (18.3 degrees Celsius).
During hot weather, our bodies will try to lose heat through our hands and feet, so keeping them outside of the covers can help cool us down. Limiting bedding and wearing lightweight, breathable sleepwear can also help regulate body temperature.
In addition to the direct impact of higher temperatures on sleep, warmer weather can also lead to increased social activity and changes in our routines, further disrupting our sleep schedules.
- Create a "sleep sanctuary" by investing in a good fan and using thinner linens and bedding.
- Wear lightweight and natural fabric sleepwear to stay cool.
- Keep your hands and feet outside of the covers to help your body lose heat.
- Exercise during the day can help improve sleep quality, but try to avoid excessive activity close to bedtime.
- Stick to a pre-sleep routine to help signal to your body that it's time to wind down and relax.
- Limit exposure to electronic devices at least one hour before bedtime, as the blue light emitted can disrupt melatonin production.
- Avoid excessive alcohol consumption, as it can interfere with slow-wave sleep and disrupt your sleep later in the night.
- Try to maintain a consistent sleep schedule, even with the longer days and warmer evenings.
- If possible, create an artificial nighttime environment by using blackout curtains or blinds to block out the sunlight.

Social calendars and work schedules
Summer can be a busy time for many, with social calendars and work schedules filling up fast. Warmer weather and longer days mean more time for socialising, which can often mean less time for sleep.
Socialising
Summer is a time when many people like to get together with friends and family. With lighter evenings and warmer weather, it's the perfect time for outdoor activities, such as bonfires, camping trips and cookouts. This can often mean staying up later than usual and disrupting your regular sleep schedule.
Work schedules
The summer slump can also affect work schedules, with many companies offering reduced hours or extra days off during the summer months. This can be a great benefit for employees, giving them more time to enjoy the warmer weather and spend time with family and friends. However, it can also mean a busier social calendar and even less time for sleep.
Striking a balance
So how can you strike a balance between enjoying the summer and getting enough sleep? Here are a few tips:
- Stick to a regular sleep schedule as much as possible, even on weekends.
- Create a relaxing bedtime routine to help you unwind and signal to your body that it's time for sleep.
- Make your bedroom a "sleep sanctuary" by keeping it cool and dark, and using lightweight bedding and sleepwear.
- Avoid excessive caffeine, alcohol and sugar, especially close to bedtime, as these can disrupt your sleep.
- Exercise during the day can help improve your sleep at night, but avoid strenuous activity close to bedtime as this may make it harder to wind down.
- If you can, try to keep your evenings free from social activities a few nights a week to give yourself time to relax and unwind.
By following these tips, you can enjoy the summer while still getting the rest you need.

Alcohol consumption
Summer is a time for relaxation and fun, and for many people, that includes drinking alcohol. However, it's important to be mindful of the impact that alcohol can have on your sleep and overall health. Here are some key points to consider:
- The impact on sleep quality: Alcohol may help you fall asleep initially, but it disrupts your sleep cycle and reduces the quality of your sleep. It delays and diminishes REM sleep, which is crucial for mental restoration. It also interferes with your circadian rhythm, the internal clock that regulates your sleep-wake cycles.
- Dehydration: Alcohol acts as a diuretic, which means it can dehydrate you as it makes you urinate more. This can be especially dangerous in hot summer weather, as dehydration combined with high temperatures can lead to a sudden increase in body temperature, potentially causing heat stroke.
- Increased risk of accidents: Alcohol slows down your reaction time and impairs your judgment. This can be dangerous when swimming or boating, as alcohol is involved in a significant number of drowning and boating accident deaths.
- Health risks: Excessive alcohol consumption is linked to various health issues, including liver disease, hepatitis, gastrointestinal problems, cognitive and neurological disorders, cardiovascular disease, and certain types of cancer.
- Sleep apnea: Alcohol consumption increases the risk of sleep apnea, a common sleep disorder that causes breathing disruptions during sleep. It relaxes the throat muscles, partially or fully blocking the airway.
- Insomnia: While some people use alcohol as a sleep aid, it can actually contribute to insomnia. It disrupts your sleep by causing frequent awakenings and reducing overall sleep quality.
- Tolerance and dependency: Regular alcohol consumption can lead to the development of tolerance, where you need to drink more to feel the effects. This can pave the way to alcohol dependency and abusive drinking patterns.
- Mental health: Chronic sleep deprivation due to alcohol consumption can impact your mental health, leading to issues such as depression and anxiety.
To maintain a healthy relationship with alcohol during the summer:
- Be mindful of your alcohol intake and set limits.
- Practice safer drinking habits, such as alternating alcoholic drinks with non-alcoholic beverages.
- Stay hydrated by drinking plenty of water, especially when consuming alcohol in hot weather.
- Avoid risky behaviours, such as swimming or boating while intoxicated.
- Seek professional help if you feel you have an unhealthy relationship with alcohol or are struggling with alcohol dependency.

Diet
- Avoid caffeine, especially at night. Caffeine is known to disrupt sleep and can make it difficult to fall asleep. Opt for decaffeinated coffee or caffeine-free drinks like chamomile tea.
- Limit your alcohol intake. Alcohol can cause dehydration and disturb your sleep, leading to frequent wake-ups during the night.
- Eat foods that help regulate body temperature. During hot summer days, avoid consuming too much animal protein, as they produce a lot of heat during digestion. Instead, opt for lighter and more soothing foods that are easier to digest, such as bananas, sweet potatoes, and oatmeal.
- Stay hydrated. Dehydration can affect the quality of your sleep, making you feel restless. Drink plenty of water and fluids throughout the day.
- Consume foods rich in melatonin and serotonin. These hormones help regulate your sleep-wake cycles. Try incorporating seafood, nuts, low-fat dairy, tart cherries, whole grains, and dark leafy greens into your diet.
- Eat dinner earlier. Avoid eating large meals close to bedtime. Finish dinner at least 2-3 hours before going to bed to give your body enough time to digest.
- Avoid spicy food at night. Spicy food can cause indigestion and make it harder to fall asleep.
- Limit your sugar intake. Sugary foods and drinks can interfere with your sleep quality. Instead, opt for natural sugars found in fruits or a tablespoon of honey, which can help increase insulin levels and promote relaxation.

Frequently asked questions
Humans are wired to sleep after the sun sets and wake when it rises. Longer days and excessive sunlight affect our hormones, particularly melatonin, which is produced by the body to make us sleepy when it gets dark. This means that in the summer, our natural sleep pattern is delayed.
To get better sleep in the summer, you can create an artificial night-time by using blackout blinds or curtains, reducing your exposure to electronic devices, and exercising. You should also try to keep your bedroom cool and wear light clothing to bed.
The health impacts of not getting enough sleep can be severe and can include decreased concentration, impaired memory, increased pain sensitivity, and poorer overall cognition. Sleep deprivation can also impact your weight, as a lack of sleep increases the amount of a hormone called ghrelin, which makes people hungrier for foods high in fat and sugar.
