Yes. Anxiety can wake you up from sleep by triggering a stress response that nudges your body toward alertness. When worry spikes—sometimes without a clear reason—your nervous system may increase heart rate, muscle tension, and “mental scanning,” making it easier to pop awake and harder to drift back off.
Anxiety and sleep are closely linked through arousal. If your brain interprets something as a threat (a stressful day, a lingering worry, a sudden noise, a vivid dream), it can release stress hormones like cortisol and adrenaline. Even a small surge can shift you into lighter sleep or wakefulness, especially in the second half of the night when sleep naturally becomes less deep.
Nighttime wake-ups can also become a learned pattern: you wake, notice you’re awake, start worrying about not sleeping, and that worry keeps you up. Over time, your brain can begin to associate the bed with alertness rather than rest.
Anxiety-related awakenings often come with a racing mind, a sense of dread, tight chest, stomach fluttering, or an urge to “solve” problems right now. Some people describe waking up suddenly, as if startled, even if nothing obvious caused it.
Keep the goal simple: lower arousal. Try slow breathing (longer exhale than inhale), relax your jaw and shoulders, and give your mind something gentle to focus on (like a calming phrase or a neutral mental image). If you’re still wide awake after about 15–20 minutes, get out of bed and do something quiet in dim light until sleepy again.

If anxiety-driven awakenings happen often, come with panic symptoms, or leave you exhausted most days, it may help to talk with a healthcare professional. Cognitive behavioral therapy for insomnia (CBT-I) and anxiety-focused therapy can be especially effective.
A racing heart at night can happen when stress hormones rise, sometimes due to anxiety, a nightmare, caffeine, alcohol, or sleep disruptions. If it’s frequent, severe, or accompanied by chest pain or faintness, check in with a clinician.
