Winter Insomnia: Why Can't I Sleep?

what does it mean if i can

Winter insomnia is characterised by difficulty falling or staying asleep during the winter months. It is not a recognised medical diagnosis and has limited research, but it is a common phenomenon with several possible causes. These include stress, pain, diet, caffeine consumption, and the dry, forced air that is typical of winter. Winter insomnia may also be a symptom of Seasonal Affective Disorder (SAD), a type of depression caused by a reduction in bright light during winter.

Lack of sunlight and seasonal affective disorder (SAD)

Winter insomnia is not an official medical diagnosis, but it can describe the difficulty of getting quality sleep during the winter season. Several factors could contribute to this, including stress, pain, caffeine consumption, and the consumption of difficult-to-digest foods before bedtime.

However, it is important to note that winter insomnia may be a symptom of Seasonal Affective Disorder (SAD). SAD is a type of depression triggered by the change of seasons and is often linked to reduced exposure to sunlight during shorter autumn and winter days. The lack of sunlight may affect the production of melatonin and serotonin, disrupting sleep cycles and influencing mood.

Melatonin is a hormone that makes you feel sleepy. In people with SAD, the body may produce higher than normal levels of melatonin, leading to increased feelings of drowsiness and irritability. To counter this, it is recommended to increase exposure to sunlight or use a light box in the morning to mimic the effects of bright sunlight.

Serotonin is a hormone that affects mood, appetite, and sleep. A lack of sunlight may lead to lower serotonin levels, which is linked to feelings of depression. Exercise can help boost serotonin levels and improve mood, sleep, and energy levels.

If you experience chronic sleep problems or persistent low mood during the winter, it is important to consult a healthcare professional for advice and potential treatment options, such as Cognitive Behavioural Therapy for Insomnia (CBT-I) or antidepressants.

Dry air and skin

Winter insomnia is not an official medical diagnosis and has limited research. However, it is characterised by difficulties falling or staying asleep during the winter. One of the factors that can contribute to this is dry air, which can trigger dry, itchy skin and irritate your nose and throat, making it hard to sleep.

Dry, cold air can make fine lines and wrinkles more noticeable. It can also cause cracked lips and itchy, dry skin. This is because the drop in temperature and lack of humidity makes it harder for your skin to retain moisture.

To combat dry skin in winter, you can try the following:

  • Use a humidifier to add moisture to the air.
  • Opt for warm showers and baths instead of hot ones, and use gentle, moisturising soaps and body washes.
  • Apply ointments, creams or moisturisers immediately after washing.
  • Wear lip balm to protect your lips.
  • Cover as much skin as possible when going outside.
  • Swap lightweight moisturisers for heavier creams.
  • Drink more water.
  • Use eye drops or an eye shield to keep eyes moist.

If at-home treatments don't work, you can see a dermatologist or doctor for advice.

Stress and pain

Winter insomnia is not an official medical diagnosis and has limited research. However, it is a term used to describe the difficulty in falling or staying asleep during the winter season. One of the factors that may contribute to this is stress.

The winter months are packed with travel, scheduling obstacles, and increased time spent indoors, which can all contribute to higher stress levels. Stress can have a negative impact on sleep quality. If you are experiencing stress, it is important to find ways to manage and reduce it. This can be done through various stress-relieving activities such as meditation, which research has shown can improve sleep quality. Other activities that may help include exercising, spending time outdoors, and engaging in calming hobbies.

In addition to stress, physical pain can also be a contributing factor to winter insomnia. The dry winter air can irritate the skin, nose, throat, and eyes, causing discomfort that may make it difficult to sleep. To alleviate this, it is recommended to use a humidifier to add moisture to the air, drink plenty of water to stay hydrated, and use fragrance-free moisturisers to soothe dry skin.

If you are experiencing chronic sleep problems during the winter, it is important to consult a healthcare professional for guidance and advice. They can help identify any underlying causes and recommend appropriate treatments or lifestyle changes to improve your sleep quality.

Caffeine consumption and alcohol

While winter insomnia is not an official medical diagnosis, it is used to describe people's difficulties with falling or staying asleep during the winter season. There are several factors that could contribute to this, including stress, pain, and lifestyle factors like caffeine consumption and napping.

Caffeine and alcohol are two substances that are known to negatively impact sleep. Caffeine is a stimulant that increases alertness and blocks our brain's perception of sleepiness, thus reducing sleep duration. Experts recommend avoiding caffeinated beverages after 2 pm as participants in a study reported that caffeine reduced their sleep quantity by 10 minutes per cup consumed the previous day on average.

Alcohol, on the other hand, affects sleep quality, causing more sleep disturbances and reducing rapid eye movement (REM) sleep. A study published in October 2021 found that higher alcohol consumption was associated with poorer sleep quality and shorter sleep duration.

Interestingly, recent research has found that consuming both caffeine and alcohol during the same day may partially mitigate their negative effects on sleep. A study conducted by researchers from the University of Washington and the University of California, Berkeley, found that among finance traders, a group known for high consumption of caffeine and alcohol, the sedating effects of alcohol lessened the negative impact of caffeine on sleep.

However, this perceived improvement in sleep does not mean that actual sleep quality has improved. The habitual use of caffeine and alcohol to counteract each other's effects is considered self-medication and can lead to a cycle of increasing reliance on both substances, ultimately resulting in deteriorating sleep quality.

To improve sleep during the winter, it is recommended to reduce caffeine and alcohol consumption, manage stress, maintain a comfortable sleep environment, and get enough sunlight or light therapy during the day to combat the effects of reduced bright light during winter, which is linked to Seasonal Affective Disorder (SAD).

Sleep apnea

There are many reasons why you may struggle to sleep in winter. This phenomenon is sometimes referred to as "winter insomnia", although this is not an official medical diagnosis. One of the main reasons for this may be the reduced exposure to sunlight during the winter months, which can cause your brain to produce more melatonin, the "sleepy hormone". This can result in Seasonal Affective Disorder (SAD), a type of depression that can cause sleep problems.

Another factor could be the dry winter air, which can irritate your nose and throat, making it harder to sleep. This dryness can also cause or exacerbate snoring and sleep apnea.

If you have sleep apnea, it is important to use your prescribed CPAP (continuous positive airway pressure) machine every night to help you breathe and get the sleep you need. CPAP machines can also reduce moisture in the nasal passages, so using a humidifier in your bedroom or a CPAP machine with a built-in humidifier can help to combat this.

Other tips for managing sleep apnea in winter include:

  • Getting sufficient light in the morning by going outside or sitting by a sunlit window.
  • Avoiding bright light at night to keep melatonin secretion on schedule.
  • Staying hydrated, as it can be harder to track your water intake during the winter months.
  • Reducing stress, which can negatively affect your sleep.
  • Exercising, which can boost your energy levels and improve your sleep and mood.

Frequently asked questions

The shorter days and longer nights in winter mean that we are exposed to less sunlight. This affects our serotonin levels, which can result in lower energy levels and a more tired feeling.

Our bodies are wired to lower our core temperature when we sleep, and sleeping in a room that is too warm can negatively impact our sleep. In winter, we tend to turn on the heating, which can make our bedrooms too hot.

We tend to eat heavier meals in the winter, and eating a large meal close to bedtime can interfere with sleep quality. It can cause gastroesophageal reflux disease (GERD) symptoms, such as heartburn and stomach discomfort, which can disturb sleep.

Try to get some sunlight, especially in the morning, as this can help to regulate your melatonin levels. You can also try exercising regularly, reducing stress, and ensuring your bedroom is a comfortable temperature.
