Sleep Texting: What It Is and Why It Happens

Quick answer: “Sleep texting” describes sending or answering messages around sleep and later having little or no memory of doing so. It may happen during partial awakening or as part of a sleep-related behavior, but a forgotten text alone does not prove someone was fully asleep or has a sleep disorder.

What is sleep texting?

Someone may find a message on their phone the next morning and not remember sending it. The message might be coherent, confusing or a response to a notification. People can also wake briefly, send a message and forget the episode later. Without an assessment, it can be difficult to know exactly what state of sleep or wakefulness occurred.

Some sleep-related behaviors fall under parasomnias, which include certain episodes of sleepwalking or acting out dreams. Sleep deprivation, irregular schedules, alcohol, some medications and other sleep disorders can contribute to parasomnias in some people. That does not mean each of these caused a particular sleep-texting episode.

How common is it?

In a survey of 372 students at two universities, 25.6% reported sleep texting. Among those reporting the behavior, 72% reported no memory of sending the message. The survey relied on self-reports and a specific college sample; it did not prove participants were asleep while texting or establish how common it is in the general population.

The same survey found associations with interrupted sleep and keeping a phone in bed. An association does not establish that a phone or notification caused the behavior.

How to reduce unwanted nighttime texts

1. Move the phone out of reach. Charge it across the room or outside the bedroom. If you rely on it for emergencies, make sure you can still hear essential calls.
2. Silence nonessential notifications. Use Do Not Disturb or a sleep mode, while allowing calls from important contacts if needed.
3. Protect private information. Use a screen lock and review notification previews. If needed, sign out of messaging apps at bedtime; choose a setup you can manage safely.
4. Allow enough sleep. Keep a regular schedule where possible and give yourself adequate time in bed. Inadequate sleep may make some sleep behaviors more likely.
5. Review potential triggers. Note alcohol, new medications, stress, interrupted sleep or symptoms such as snoring. Do not stop prescribed medication without consulting your clinician.

When should you talk to a clinician?

Ask for help if episodes recur, disrupt sleep, cause distress or occur alongside sleepwalking, injuries, leaving the house, gasping, loud snoring or significant daytime sleepiness. Keep a brief log of the time, messages sent, medications and what a bed partner observed. A clinician may assess other sleep disorders or recommend a sleep specialist.

If a sleeping medication is associated with complex behaviors such as sleepwalking, driving or other activities while not fully awake, contact the prescribing clinician promptly for guidance. Do not drive while drowsy.

Frequently asked questions

Can someone send a coherent text while asleep?

A message can appear coherent, but the message itself cannot confirm the sender's sleep state. Partial awakenings and later memory gaps are also possible.

Should I put my phone in another room?

It can reduce access and interruptions. If you need emergency calls or an alarm, choose a setup that keeps those functions available.

Does sleep texting mean I have sleep apnea?

No. Sleep apnea is one possible source of sleep disruption, but many people who forget a message do not have it. Ask a clinician about snoring, gasping or daytime sleepiness.
