Long Summer Days Affecting Your Sleep?

It’s hard to sleep when the sun is high. Try these tips to rest easy.

Why is it harder to sleep in the summer?

Researchers found that waking times were earlier in the summer, while sleep issues such as insomnia and fatigue were less common in winter (although people can still have sleep issues in winter). 

Here are some reasons you may not be sleeping as well during summer.

Increased daylight hours

With the long days and high temperatures, it’s hard to get a good night’s sleep.

Your body clock, which is located in your brain, uses light and darkness as signals for day and night. The longer we ‘see’ light, the longer the body clock will tell the body it’s daytime and it needs to stay awake.

Delayed melatonin release

As the sun sets, our body clock signals that it’s time to sleep with melatonin release. As this chemical is secreted in response only at night-time and when there are no artificial lights or waves interference on its production; as soon as evening comes around – boom! You’re good for another hour of shut eye (or however long until your usual bedtime).


Sleep may be further disrupted if you’re stressed or have a lot on your mind. Hormones and chemicals play a huge role in our ability to maintain balance and homeostasis.

For example, the hormonal changes of menopause or the adrenal and chemical imbalances from anxiety and stress “will have a huge impact on our ability to release melatonin effectively and ultimately switch off.

Lifestyle factors

Lifestyle factors may also be at play. Because the days are longer, we generally do more, and also find our socializing increases. With the summertime lifestyle being more social, we may find we’re eating later and drinking more alcohol.

Higher temperatures

Combined with longer daylight hours, higher temperatures can also play a part in disrupting sleep. 

When we’re too warm, our body moves out of the relaxed state and very subtly moves into a heightened state of awareness.
