When a client tells me she's exhausted, wired at night or waking at 3am, sleep is one of the first things I look at. It's one of the most powerful tools you have for calming your nervous system, and one of the first things to suffer when you're under stress.
why sleep matters for your nervous system
Sleep isn't a passive state. In deep sleep your body does much of its repair work, and your stress response gets a chance to switch off. REM sleep helps with memory, learning and processing emotions. When sleep is short or broken, you feel it the next day: a shorter fuse, a stronger stress response and less in the tank for everything else.
1. anchor your body clock
Your circadian rhythm, your body's internal 24-hour clock, decides when you feel alert and when you feel sleepy. Late screens, irregular bedtimes and bright evening light all blur it. Light, temperature and when you eat are the main signals it listens to. A consistent wake-up time, even at weekends, is the single most useful habit.
2. use light on purpose
morning: get bright light within 30 to 60 minutes of waking, outside if you can. It helps set your body clock for the day, which makes it easier to feel sleepy at night.
late afternoon: if you can, get outside again before the sun sets.
after sunset: keep lights low and warm. Use lamps instead of overhead lights, and dim your screens.
3. work with your temperature
Your body temperature drops as you get ready to sleep. A warm shower or bath an hour or two before bed helps, because your body cools down afterwards. Keep your bedroom cool. Exercise earlier in the day tends to help sleep, while gentle stretching suits the evening.
4. if bed has started to feel stressful
After a run of bad nights, bed itself can start to feel stressful, and that worry keeps you awake. CBT for insomnia (CBT-I) is the most effective treatment for long-term insomnia, and it's worth asking your GP about. Practices that calm your nervous system can help alongside it.
When you're lying awake, try not to fight it. Notice what's happening in your body instead. If your stomach feels tight, see what happens when you let it soften and breathe into it. Moving from fighting sleep to accepting where you are often takes the pressure off.
5. simple tools to help you settle
These aren't quick fixes, but they can help your body feel safe enough to rest:
gentle tapping: tap your fingers lightly on the bed in a slow rhythm and focus on the feeling, not on falling asleep
a weighted blanket: the deep pressure feels calming for many people, and around 10% of your body weight is a common guide
an eye mask: it blocks out light, and the gentle pressure feels soothing for some people
6. after a bad night
Yoga nidra and non-sleep deep rest (NSDR) are guided practices that take you into deep relaxation while you're awake. They won't replace sleep, but many people find they take the edge off a bad night and ease the worry about the next one.
putting it together
Better sleep isn't about doing everything perfectly. Pick one or two of these, try them for a few weeks and notice how you feel. If you've had trouble sleeping for months, talk to your GP too, because sleep problems can have medical causes that are worth ruling out.
