You fall asleep fine. Then, at some point in the middle of the night, you are wide awake. Your mind starts going. You look at the clock. It is 3 am. Sound familiar?
Waking in the night is extremely common, and it becomes more common as we get older. Understanding why it happens is the first step to doing something about it.
Why sleep changes over time
Sleep is not one long block. It happens in cycles, roughly 90 minutes each, moving between light sleep, deep sleep and REM sleep. As we age, we spend less time in deep sleep and more time in lighter stages. This makes us easier to wake up, and once awake, harder to get back to sleep.
Common reasons for waking at night
Temperature changes are one of the biggest culprits. During menopause, hot flashes and night sweats can wake you suddenly and repeatedly. Even without menopause, body temperature regulation changes with age.
Needing to use the bathroom is another common cause. The bladder tends to become less able to hold urine through the night.
Pain, whether from joints, back, or other conditions, can interrupt sleep without you always realising that pain is the cause.
Anxiety and a busy mind are also very common triggers. Stress tends to surface when we have nothing else to focus on.
What actually helps
Keeping your bedroom cool and dark makes a real difference. Your body needs to drop in temperature to stay asleep.
Avoid screens for at least an hour before bed. The blue light from phones and tablets signals to your brain that it is daytime.
If you wake up and cannot get back to sleep within 20 minutes, get up. Do something quiet and calm in dim light, then go back to bed when you feel sleepy again. Lying in bed anxious about not sleeping, makes things worse.
A consistent wake time, even at weekends, helps to anchor your sleep cycle. It is one of the most evidence-backed changes you can make.
If sleep problems have been going on for more than a few weeks and are affecting your daily life, it is worth talking to your doctor. Cognitive Behavioural Therapy for Insomnia (CBT-I) is the most effective long-term treatment and does not involve medication.
