Sleep in adults: the basics worth editing

Duration is not the only measure

The CDC states that most adults need at least seven hours of sleep, with differences based on age and individual needs. Continuity of sleep, feeling rested and daily functioning are also important.

One bad night is not a disease. A problem becomes more important when it persists, impairs work, mood or safety.

Habits you can test

Make one change and follow it for two weeks. A consistent time to get up often helps the body adjust to a rhythm.

• expose yourself to daylight earlier in the day
• cut back on caffeine late in the day
• create a calm bedtime routine
• avoid driving when you are extremely sleepy

When to talk to an expert

Persistent insomnia, restless legs, suffocation or interrupted breathing in sleep and severe daytime sleepiness have different causes. The assessment is better than long-term self-administration of sleep aids.

Stabilise the rhythm before fine-tuning details

A consistent waking time is often a more practical starting point than trying to force sleep. Morning light, daytime activity and limiting long late naps help the body distinguish day from night. Judge a change over several days rather than after one night.

An evening routine should be simple and repeatable. Reduce bright light and stimulating content, allow time to wind down and keep the room quiet, dark and comfortable. Alcohol may cause drowsiness but disrupts sleep quality and is not a treatment for insomnia.

When sleep problems need assessment

Speak with a clinician when problems persist, significantly affect daytime function or occur with loud snoring, pauses in breathing, morning headaches or uncontrollable daytime sleep episodes. A two-week record of bedtime, waking, naps and caffeine can support the assessment.

If sleepiness makes driving or machinery unsafe, stop the risky activity. Sleeping tablets and supplements can cause adverse effects and interactions, so do not start or combine them without professional advice.

Keep a short sleep record

For two weeks, record bedtime, estimated time to fall asleep, night waking, waking time, naps, caffeine and alcohol. The aim is not perfect precision but a pattern that can support a clinical conversation.

Avoid repeatedly checking the clock at night. If sleep does not come for a long time, a calm activity in low light may be better than remaining in bed while tension rises. Return when sleepy.
