Many people who sleep reasonably well for most of the year find themselves wide awake at 2am once summer arrives. Longer daylight hours, higher temperatures, and disrupted routines all interfere with the body’s natural sleep signals, making insomnia more common during the warmer months.
While it is often dismissed as a minor seasonal inconvenience, persistent sleep disruption can affect mood, concentration, and overall wellbeing. At Bridges Therapy Centre, our sleep therapy in London helps individuals address insomnia at its root, whatever the time of year.
Why Summer Disrupts Sleep
The body relies on darkness to trigger melatonin production, the hormone that signals it is time to sleep. Longer daylight hours delay this process, particularly for those without blackout curtains. Heat compounds the problem, as the body needs to cool slightly to fall and stay asleep, which is harder to achieve in a warm bedroom.
Holiday periods, later evenings, and irregular routines common in summer also disrupt the consistency that healthy sleep depends on, even for people who do not normally struggle with insomnia.
When Seasonal Sleep Trouble Becomes a Bigger Problem
Occasional restless nights during a heatwave are normal. However, if sleep difficulties persist for several weeks, or if anxiety about not being able to sleep starts to develop, this can indicate a more entrenched pattern of insomnia that will not resolve simply because the weather changes.
At Bridges, we use Cognitive Behavioural Therapy for Insomnia (CBT-I) to identify and change the thoughts and behaviours maintaining poor sleep, alongside Acceptance and Commitment Therapy (ACT) to reduce the anxiety that often builds around sleeplessness itself.
