Most people who wake up with a stiff neck or an aching back blame the pain and stop there. But back trouble is far from a niche complaint. Low back pain is the single leading cause of disability in the world, affecting around 619 million people in 2020, and researchers expect that to climb to 843 million by 2050. Somewhere between 60 and 80 percent of us will deal with it at some point. So when it starts wrecking your sleep, you’re in a very large crowd.
In this Q&A, Dr. Ram Chaddha, a consultant spine surgeon in Mumbai with more than 30 years of experience, answers a patient describing exactly that problem: sleep that never feels deep enough, a sore neck in the morning, and rest that keeps getting broken up through the night. His answer is worth reading in full, because almost none of it is about medication. It’s about what you do in the two hours before bed, the bed itself, and picking a pillow that matches how you actually sleep.
Here’s the conversation, followed by a breakdown of each point.
Start before you lie down
The first mistake happens at the dinner table. Dr. Chaddha’s rule is to leave at least two hours between your last meal and bed. Eat too close to lying down and you get indigestion, and indigestion is one of the things that keeps you awake in the first place.
The science backs him up. Lying down on a full stomach makes acid reflux more likely, and eating a heavy meal near bedtime interferes with both digestion and sleep. Survey studies have found that people who eat within about three hours of going to bed are roughly twice as likely to report poor sleep quality as those who finish earlier. His two-hour gap is a sensible minimum.
The second habit is the one most people skip: tire your body out on purpose before bed. The point is that you should feel sleepy because your body is spent, not just because the clock reads 10 p.m. A short walk after dinner does the job. Finish eating at 8, take a half-hour walk, and by 10 you’re actually ready to sleep instead of lying there waiting for it.
This is not just folk wisdom. Johns Hopkins sleep specialists say there’s solid evidence that exercise helps you fall asleep faster and improves sleep quality, and that moderate aerobic activity increases the amount of slow-wave (deep) sleep you get, which is the stage this patient says he’s missing. You don’t need a workout. Regular, moderate movement such as a daily walk is enough to shorten the time it takes to drift off.
Getting the bed right
There’s a common belief that a harder surface is better for your back. Dr. Chaddha pushes back on it, and so does the research. A hard board and an extra-soft bed are both wrong. What you want is a firm mattress. His own preference is foam and coir used together, which gives you support without the surface being punishing.
The old “sleep on something hard” advice turns out to be exactly backwards. In a randomised trial of 313 people with chronic low back pain, those given a medium-firm mattress were about twice as likely to see their pain improve, whether in bed, on rising, or in day-to-day function, as those given a firm one. For years most orthopaedic surgeons had recommended firm mattresses anyway, and the evidence didn’t support them. This is why “my back hurts, so I’ll sleep on the floor” is a punishment, not a treatment. Falling asleep properly is part of staying healthy, and a hard floor works against that.
Bed height matters too, and it’s the thing people rarely think about. The bed shouldn’t sit too low. A slightly higher bed means you’re not straining to get down to it and back up again, which matters more as you get older.
Choosing a pillow for how you actually sleep
This is where the advice gets specific, and it’s the part most people get wrong. There is no single correct pillow. The right one depends on the position you spend most of the night in.
If you sleep on your back
When you’re flat on your back, in the supine position, with the back of your head (the occiput) resting on the bed, you need a thin, small pillow. A thick pillow here pushes your head forward and strains your neck.
If you sleep on your side
Side sleeping is a different geometry. When you lie on your side, the gap between the bed and your ear is much larger than the gap at the curve of your neck. To keep your neck in line with your spine, you need a thicker, higher pillow to fill that space. Use a thin one and your head drops, which is exactly the kind of thing that leaves you with a sore neck by morning.
This is worth paying attention to, because most people are side sleepers. The patient in the video says it plainly: he can only sleep on his left or right side and can’t manage the flat-on-the-back position at all. Dr. Chaddha agrees that’s normal. Very few of us actually sleep in that neat, face-up “yoga pose” people imagine.
The contoured pillow trick
If you move between your back and your side during the night, a contoured pillow solves both at once. These have a higher hump on one edge and a lower hump on the other. Dr. Chaddha uses one himself: when he shifts from lying on his back to lying on his side, he just flips or swaps the pillow to the side that fits that position. One pillow, two heights.
Two things people forget
A couple of smaller points from the conversation are worth keeping.
If you’re older, plan the walk to the bathroom and back so you can do it safely in the dark. Night-time falls are a real risk, and a clear path matters.
And skip the midnight snack. Eating late tends to keep you awake rather than send you off to sleep. Dr. Chaddha points to a modern version of this problem: with streaming services, people settle in to binge-watch and end up binge-eating at the same time, late into the night. Both work against the sleep you’re trying to get, and as the meal-timing research above shows, that late food is quietly costing you sleep quality on top of the calories.
The bottom line
Better sleep here isn’t about a gadget or a supplement. It comes down to a few adjustments: leave a gap after dinner, tire yourself out a little, sleep on a firm mattress at a sensible height, and match your pillow to whether you sleep on your back or your side. If you switch positions through the night, a contoured pillow saves you the trouble of choosing.
If neck or back pain is disturbing your sleep night after night, these changes are a sensible starting point, though persistent pain is worth taking to a doctor who can look at your specific situation.
