Sleep anxiety

Sleep anxiety isn't a formal diagnosis but a common experience that sits where anxiety and sleep problems meet. Some people feel anxious specifically about sleep, for example worrying that they won't get enough rest and will struggle the next day. Others notice that general anxiety intensifies at night, when distractions fade and the mind is free to wander.

Anxiety and sleep have a two-way relationship. Anxiety makes it harder to fall and stay asleep, and poor sleep increases anxiety. Over time, the bed itself can become linked with worry and wakefulness, which is one way that sleep anxiety can turn into ongoing insomnia.

Sleep anxiety can affect anyone, but it's more common in people with anxiety disorders, depression, trauma or chronic stress. Children can also experience nighttime fears and anxiety about sleeping alone.

With the right strategies, many people can retrain their body and mind to associate bedtime with rest rather than alarm.

Signs of sleep anxiety and nighttime anxiety include:

• Dreading bedtime or feeling tense as night approaches
• Racing thoughts, worry or replaying the day when you lie down
• Clock-watching and calculating how much sleep you'll get
• Physical symptoms in bed: racing heart, muscle tension, restlessness, shallow breathing
• Difficulty falling asleep, or waking in the night and being unable to get back to sleep
• Waking early with a sense of dread
• Feeling tired yet wired
• Avoiding bed or delaying bedtime with screens or activities
• Worry about how poor sleep will affect your health or performance

Some people experience nocturnal panic attacks: waking suddenly with intense fear, a pounding heart, sweating, trembling or breathlessness. These can be frightening and may lead to further fear of sleep.

Because some of these symptoms can overlap with medical conditions such as sleep apnea, heart problems or thyroid issues, it's worth discussing them with a doctor, particularly if they're new.

Many people notice that anxiety at night feels stronger than during the day. Several factors explain this:

• Fewer distractions: during the day, work and activity keep worries at bay; at night, the mind has space to ruminate
• Tiredness: fatigue reduces our ability to regulate emotions and put worries in perspective
• Anticipatory anxiety: worry about not sleeping triggers the stress response, which is incompatible with sleep
• Conditioned arousal: after repeated restless nights, the bed itself can trigger alertness
• Body rhythms: natural changes in hormones and body temperature through the night can make physical sensations more noticeable
• Lifestyle factors: caffeine, alcohol, late meals, screens and irregular schedules can all worsen nighttime anxiety

Underlying conditions such as generalized anxiety disorder, panic disorder, PTSD and depression also tend to disrupt sleep. Nightmares, common after trauma, can make people fearful of going to sleep.

Understanding these reasons can be reassuring: nighttime anxiety is a predictable pattern, not a sign that something is seriously wrong.

Somniphobia, sometimes called fear of sleeping, is an intense fear of falling asleep. People with this fear might worry about having nightmares, not waking up, losing control, sleep paralysis or something bad happening while they're asleep. They may stay up very late, sleep with lights or a TV on, or avoid sleep altogether, leading to exhaustion.

Nocturnal panic attacks are panic attacks that wake a person from sleep. They're not the same as nightmares; they usually happen without a dream and come with strong physical symptoms. They're more common in people who also have daytime panic attacks.

Both can create a vicious circle: fear of what might happen at night makes sleep harder, and exhaustion increases anxiety.

Other experiences that can feed sleep fears include sleep paralysis, night terrors and trauma-related nightmares. A clinician can help identify what's happening and recommend treatment, which may include addressing underlying trauma or panic.

Cognitive behavioral therapy for insomnia (CBT-I) is widely recommended as a first-line treatment for persistent sleep problems and is very effective for sleep anxiety. It includes:

• Stimulus control: using the bed only for sleep and getting up if you can't sleep
• Sleep scheduling: regular wake times and, sometimes, temporarily limiting time in bed to strengthen sleep drive
• Cognitive techniques to reduce catastrophic thoughts about sleep
• Relaxation methods and a wind-down routine

CBT for anxiety or panic can help when daytime anxiety drives the problem, and trauma-focused therapy can help with trauma-related nightmares.

A psychiatrist or doctor may discuss short-term medication in some situations, but many sleep medications aren't recommended long-term. Decisions should be made with a professional.

Strategies to try now:

• Keep a consistent wake-up time
• Write worries down earlier in the evening
• Limit caffeine after midday
• Dim screens and lights before bed
• Practice slow breathing or progressive muscle relaxation
• If you're awake, get up and do something calm until sleepy

Consider seeking help if sleep anxiety is happening most nights for several weeks, affecting your mood, concentration or work, or if you're relying on alcohol or other substances to sleep. Nocturnal panic attacks, frequent nightmares or an intense fear of sleeping are also good reasons to talk to a professional.

Your primary care doctor can rule out physical causes, such as sleep apnea or medication side effects. A psychologist, clinical psychologist or psychiatrist can assess for anxiety, panic disorder, depression or trauma and provide treatment such as CBT-I.

In a first appointment, expect questions about your sleep patterns, bedtime routine, worries, daytime anxiety, mood, caffeine and alcohol use. You may be asked to keep a sleep diary for a week or two.

If anxiety and sleeplessness are accompanied by hopelessness or thoughts of self-harm, seek help right away: call 911 or your local emergency number, or call or text 988 in the US (Samaritans 116 123 in the UK and Ireland).
