Is it a problem that I often wake up during the night?
Waking up occasionally is normal, but if it happens frequently and affects you during the day, there may be an underlying cause such as sleep apnea or PTSD. In that case, have it checked out.
Waking up occasionally is normal. At home, you wake up on average about twice a night. If you fall back asleep quickly and feel fine during the day, there is little to worry about. Does it happen more often, do you lie awake for long periods, or do you feel drowsy during the day? Then it is something to take seriously.
The most common medical cause is sleep apnea: your breathing repeatedly stops while you sleep. This fragments your sleep and can startle you awake with a feeling of breathlessness. Sleep apnea is also associated with high blood pressure, atrial fibrillation, type 2 diabetes, and stroke. Does a bed partner wake up because of your snoring, or do they notice that you stop breathing? If so, see your doctor.
Other conditions that significantly worsen nighttime waking are PTSD, dementia, and in children, autism. With PTSD, the wake-ups are often accompanied by nightmares. With dementia, 40% of people suffer from sleep problems, which makes memory problems and the risk of falls even greater. In children with autism, the proportion with sleep problems ranges from 40 to 86%.
There are two medications with reasonably good evidence, but both warrant caution. Trazodone (an antidepressant that also promotes sleep) reduces the time spent lying awake after initially falling asleep by an average of just over 13 minutes, but also causes more side effects. Sleeping pills based on benzodiazepines give the feeling of sleeping better, but disrupt deep sleep and can cause concentration and memory problems. Use them only under close medical supervision.
What can you do yourself? In people with dementia, more physical activity and social engagement during the day helps somewhat against nighttime waking, although the evidence is limited. For everyone: if you fall back asleep quickly and feel fit during the day, there is probably nothing wrong. Do you regularly lie awake for long periods or feel tired during the day? Then discuss it with your doctor.
Based on multiple studies with associational evidence; no large controlled trials for the sleep quality outcome itself. Additionally, a meta-analysis for trazodone and a review study for sleep apnea. Total participant numbers are an estimate based on the studies cited.
Why do I wake up tired even after sleeping for a long time?
Waking up tired despite sleeping for a long time is a normal phenomenon called sleep inertia, and the time of waking and evening screen use play a clear role in it. Limit screens before bedtime and keep naps short (around 30 minutes) to avoid the worst grogginess.
How bad is screen light in the evening for my sleep?
Screen light in the evening disrupts your sleep hormone and keeps you less sleepy at the wrong moment. Dim your screens after dinner, or wear amber-tinted glasses if you still need to work.
Why am I wide awake in the evening when I feel tired during the day?
Your biological clock and your chronotype determine when your body wants to be awake. When that clock does not align with your daily schedule, you feel tired during the day and wide awake in the evening. Light exposure at the right time and a consistent sleep schedule are the most well-supported ways to correct this.
Why do I dream so much, and is that good or bad?
Simply dreaming a lot is normal and need not be a cause for concern. However, persistent nightmares or dreams that you physically act out during sleep are signals that should be taken seriously and discussed with your GP.
Does a consistent morning routine with daylight help you fall asleep more easily in the evening?
A consistent morning routine with daylight helps sharpen your biological clock, allowing you to fall asleep earlier and more easily in the evening. The evidence is not perfect, but consistent enough to make it worthwhile: step outside briefly shortly after waking up.
Do I sleep worse if I am often alone or feel lonely?
Yes, loneliness is clearly associated with poorer sleep: you have more difficulty falling asleep, wake up more often during the night, and feel more tired during the day. Working on social connection is therefore also a concrete step toward better nights.
