Sleep Hygiene Checklist

Sleep hygiene is the set of daily habits and environmental conditions that make good sleep more likely. The term sounds clinical, but it simply describes the routine behaviours - timing, light, temperature, caffeine, screens and wind-down - that either support or sabotage your sleep. None of these on its own guarantees a perfect night, and they are not a treatment for a sleep disorder, but together they form the foundation that almost every other sleep strategy is built on. The checklist below is practical and cumulative: adopt a few items at a time rather than overhauling everything at once, and give changes a couple of weeks to take effect.

Consistency is the single most powerful sleep-hygiene habit. Go to bed and, more importantly, get up at roughly the same time every day, including weekends. Regular wake times anchor your body clock so that sleepiness arrives reliably at night. Build a calming wind-down of 30 to 60 minutes before bed - dim the lights, step away from work, and do something low-key such as reading or gentle stretching. A predictable sequence signals to your brain that sleep is coming. Avoid long or late naps, which can blunt your sleep drive; if you must nap, keep it short and early in the afternoon.

Light is the strongest signal to your body clock, so use it deliberately. Get bright daylight early in the day, ideally outdoors, to reinforce daytime alertness and keep your rhythm anchored. In the evening, do the opposite: lower overhead lighting, use warmer lamps, and reduce screen brightness in the last hour before bed, as bright light suppresses the natural rise of melatonin and delays sleepiness. Make the bedroom as dark as practical with blackout curtains or an eye mask. If you wake in the night, keep any lights you use dim, since bright light is alerting and can make settling again harder.

A slight drop in core body temperature helps trigger and maintain sleep, so a cool bedroom generally beats a warm one. Many sleep guidelines suggest a bedroom temperature in the region of 16 to 18 degrees Celsius, adjusted to personal comfort. Keep the room well ventilated, choose breathable bedding, and avoid going to bed overheated. A warm bath or shower an hour or two before bed can help, somewhat counterintuitively, because the body sheds heat afterwards and that cooling supports the transition into sleep. Cold feet can delay sleep onset for some people, so warm socks are a reasonable fix.

Caffeine has a long half-life and can linger in the system for many hours, so avoid it from around midday or early afternoon if you are sensitive. Remember that tea, cola, energy drinks and chocolate contain caffeine too. Alcohol may help you drop off but fragments sleep later in the night, so keep it modest and well before bed. Leave a couple of hours between a large meal and sleep to avoid digestion disrupting the night, though a light snack is fine if hunger would otherwise keep you up. Stay hydrated through the day but ease off fluids close to bedtime to reduce night-time trips to the bathroom.

Keep the bedroom for sleep and intimacy so your brain associates it with rest rather than work or scrolling. Reduce noise with earplugs or a steady background sound if needed, and keep the space tidy and uncluttered. If your mind races at bedtime, jot worries or tomorrow's tasks on paper earlier in the evening to park them. If you cannot sleep after about twenty minutes, get up, keep the lights low, and do something calm until you feel sleepy again rather than lying frustrated. Where supplements feature, food supplements are not medicines; magnesium, which contributes to the reduction of tiredness and fatigue, may sit within a routine but does not replace these habits. If poor sleep persists for weeks, speak to a GP.
