Sleep and recovery: why does everything hurt more after a bad night?
Key points
- Most of your recovery happens while you sleep: this is when your nervous system rests, and when whatever the day or your training put under strain gets rebuilt.
- Sleep and pain affect each other: pain makes sleep worse, and too little sleep can make you more sensitive to pain.
- A good night starts in the evening: a cool, dark bedroom (18–19 °C), a screen-free last half hour, and a short wind-down for tight areas of the body.
- To relax, a massage gun on a low speed, a warm compress or the calming mode of a cupping device can all help.
- Breathing through your nose matters during sleep too: your nose filters, humidifies and warms the air, and you don't wake up with a dry mouth.
- If you have been sleeping badly for weeks, struggle to keep your eyes open during the day, or others say your breathing stops while you sleep, talk to your doctor.

Training plans, diet, stretching: most conversations about recovery revolve around these. Yet the biggest recovery tool is free for everyone, every night. We just tend to cut it short for a bit of work, a TV series or some late-night scrolling.
In this article we look at what happens to your body during sleep, why everything hurts more after a bad night, and what you can do in the evening to fall asleep more easily and wake up more rested. We compared the devices that support nose breathing separately, in the guide to nasal strips, nasal dilators and mouth tape.
What happens to your body at night?
During sleep your body doesn't switch off, it switches to a different mode. Your muscles relax, your heart rate and breathing slow down, and during deep sleep, hormones are released that play a part in tissue renewal. That is why people say muscle is rebuilt not during training but afterwards, during rest.
A night consists of several cycles of roughly an hour and a half, and in each one light sleep, deep sleep and dreaming alternate. There is more deep sleep in the first half of the night and more dreaming in the second half. If you regularly go to bed late but get up early, you get less of both.
How much is enough? For adults, 7–9 hours of sleep is generally recommended. If you train a lot or do physically demanding work, you need the upper end of that range rather than the lower.
Sleep and pain: why do they reinforce each other?
Because the relationship works both ways. If your back or shoulder hurts, it is harder to find a comfortable position, you wake up more often, and you sleep worse. Too little or broken sleep, in turn, can make you more sensitive to pain, so the next day the same tension feels stronger. The easiest way out of this cycle is an evening routine.
According to a 2020 review, pain can be both a cause and a consequence of sleep deficiency, and this two-way relationship also matters for preventing long-lasting pain. The authors also reviewed several nervous system and hormonal processes through which too little sleep can amplify the perception of pain (Haack et al., Neuropsychopharmacology, 2020, PubMed 31207606).
What we take from this: it is worth moving and relaxing the aching areas of your body in the evening, before bed, not in the morning rush. If the tension eases in the evening, it is easier to find a comfortable position, and you are more likely to sleep through the night.
Less sleep, weaker training?
Often, yes, but not equally in every respect. Research suggests that a few short, maximal efforts may hold up even after a bad night, while sport-specific performance, reaction time and decision-making get worse. Lack of sleep can also amplify the body's stress response, which in the longer term can lead to symptoms similar to overtraining.
A 2015 review of sleep in athletes summed it up like this: after too little sleep, athletes' sport-specific performance decreased, and participants became slower and less accurate in cognitive tasks. The authors added that the results of the studies do not agree in every respect and more research is needed (Fullagar et al., Sports Medicine, 2015, PubMed 25315456).
In practice, this means a hard training week depends on sleep at least as much as on the training plan. If you were to change just one thing, we would start with your bedtime, not with another workout.
The last hour before bed: 5 steps
A good night largely depends on the last hour. A cool, dark room, a screen-free last half hour, a short wind-down for tight areas and a few minutes of slow breathing: together, these help your body switch over to rest.
- A cool, dark bedroom. Keep it at 18–19 °C, with dim lights. In the cool, your body temperature drops more easily, which helps you sleep more deeply.
- A screen-free last half hour. Leave your phone outside the bedroom, or at least out of your hand. This way your brain gets no new stimuli and quietens down more easily.
- 10 minutes of relaxing tight spots. Neck, shoulders, lower back or calves: work where the most tension has built up during the day. This way you are not focused on the pain when you lie down.
- Slow breathing, through your nose. Breathe in for 4 seconds and out for 6 seconds, for 5 minutes. The longer exhale slows your heart rate and shifts your body into a resting state.
- Same time every day. Go to bed and get up at roughly the same time, weekends included. This way your internal clock gets used to it, and sleepiness comes naturally in the evening.
A heavy dinner, alcohol and late-afternoon coffee can also make your sleep worse, even if falling asleep is easy. If you still wake up several times a night despite the routine, these are worth starting with.
Winding down in the evening with a device: massage gun, cupping device, compress
In the evening, the goal is relaxation, not deep muscle work. Use the massage gun on a low speed and move it slowly, choose the gentler mode on the cupping device, and place the warm compress on the tight area. A few minutes per area is enough, and the whole thing takes no more than 10–15 minutes.
- Elit Massage Gun: with 30 speed levels, it can be adjusted from the gentlest vibration to firm deep work, so it also works well in the evening on a low speed for relaxation. Its noise level is 45 dB. We described which head to use on which body area and for how long in our massage gun guide by body area.
- CUPPER Cupping Device: it has two modes, a deep negative pressure mode and a gentler, restful calming mode. In the evening we recommend the calming mode. The device switches off automatically after 20 minutes.
- Cryoflex compress: warms up in the microwave in 30 seconds, then you place it on your skin. It should feel warm to the touch, not hot; if needed, warm it further in 10-second steps. It fits on the knee, ankle, elbow, forearm and calf.
Nose breathing during sleep: why does it matter?
Your nose filters, humidifies and warms the air you breathe in, and breathing through your mouth skips all of this. People who breathe through their mouth at night often wake up with a dry mouth and a scratchy throat, and feel less rested. That is why it pays to make sure your nose does the work during sleep too.
Several devices can support nose breathing: nasal strips, a magnetic nasal dilator and mouth tape. We described in detail what each one does and which one to start with in the guide to nasal strips, nasal dilators and mouth tape, and how to fit a magnetic nasal dilator in the magnetic nasal dilator article.
The Easy Sleep Pro magnetic nasal dilator supports calm breathing through the nose during sleep. It is drug-free and contains no active ingredients, it is reusable, and in the morning you can clean it with a little lukewarm, mildly soapy water.
When should you see a doctor?
An evening routine helps a lot, but it doesn't replace a medical examination. If you have been sleeping badly for weeks, struggle to keep your eyes open during the day, or your partner says your breathing stops from time to time while you sleep, don't experiment with devices: talk to your GP.
Talk to your doctor if:
- for more than three or four weeks you have trouble falling asleep or regularly wake up at night;
- you are much sleepier than usual during the day, even while driving;
- you snore loudly in your sleep, and your partner says your breathing stops from time to time;
- pain has kept you from sleeping through the night for weeks.
If you have any health condition, ask your doctor before using the massage gun, the cupping device or the compress as well.

Most recovery happens at night, and sleep and pain affect each other: if you sleep badly, you hurt more, and if you hurt, you sleep worse. The easiest way out of this cycle is an evening routine: a cool, dark room, a screen-free last half hour, 10 minutes of relaxing tight spots and slow breathing through your nose. If you have been sleeping badly for weeks, or your breathing stops during sleep, don't experiment with devices, talk to your doctor.
