If you regularly wake up with stiff muscles, creaky joints, or the general feeling
that your body simply isn’t as limber as it was when you went to bed, the first
thing to know is that you are not alone. Waking up with a tight body is “almost
a universal human experience,” said Maryclaire Capetta, a physical therapist
and assistant professor in the department of kinesiology at the University of
Connecticut. And, she added, it’s quite common for it to happen every day.

But while feeling stiff in the morning is normal and typically dissipates
quickly, it’s also uncomfortable while it lasts. The good news, experts say, is
that there are a few tricks you can use — when you feel stiff, and even before
the feeling arises — to help you get relief, faster.

Why You Feel Stiff

Most of the time, that tight feeling when you wake up is a result of overnight
changes to the lubrication in two different features of the body: the joints and
the fascia.

A fascia is a complex group of connective tissues that surround and support
the muscles, soft tissues, organs and bones. Think of fascia as a fibrous web
that wraps around and through muscle tissue to give it structure and stability.
It forms multiple layers, with a gel-like lubricant in between that allows the
layers to slide and glide smoothly, and which helps you to feel loose and
limber, said Dr. Antonio Stecco, a fascia researcher and professor of
rehabilitation medicine at New York University.

In certain situations — like when your body temperature drops, when you’ve
been still for an extended time, or when lactic acid builds up in the muscles
and fascia during intense exercise — the lubricant becomes thicker and more
viscous and the layers of fascia can’t glide as easily, leading to feelings of
stiffness.

When you sleep, many of those thickening situations occur: you’re usually still
for a long time (say, eight hours) and your body temperature tends to drop.
Your joints may also contribute to feeling stiff in the morning. In healthy
joints, a thick fluid lubricates the space between the ends of your bones,
which are capped with cartilage, to help them move freely and comfortably.
Whenever you’re still for a long period of time (like when you’re sleeping), the
cartilage sucks up the lubricant like a sponge, Capetta said, making your
joints feel creaky.

How to Feel Better

The good news is that the remedy for stiffness in the morning — whether it’s
caused by your fascia or your joints — is the same: movement.

While you’re still in bed and lying on your back, start by doing a full-body
stretch, like a cat or dog does when they first wake up, by extending your legs
and arms wide and in opposite directions. Then, try pointing and flexing your
toes, or stretching just your arms and torso, mimicking the cliche “just woke
up” stretch. To bring fluid back into your joints, try gently bending and
unbending your knees and elbows, rolling your wrists and ankles, or gently
nodding your head from side to side.

If you still feel stiff once you’ve gotten out of bed, try marching in place,
continuing to bend and re-bend any joints that feel stiff, Capetta said. If your
back and the sides of your body feel tight, you could try a gentle stretch, like a
loose forward hang toward your toes with slightly bent knees, or side bends
and cat-cow yoga poses. Studies suggest that a regular yoga practice can be
effective in reducing discomfort associated with joint and muscle stiffness
and chronic back pain. Do whatever feels good. If you have a dog, taking it out
first thing in the morning might get your body’s juices flowing and help you
feel nimble more quickly. If it’s cold in the morning, try a hot shower.

While it’s healthy and normal to feel a little tight after a night of stillness, you might feel even more tight if your baseline flexibility is already limited. You can lessen this by staying limber and maintaining an active lifestyle in general. If you don’t already stretch regularly, adding even 15 minutes of stretching to your day may help you feel less stiff upon waking, Stecco said. If you sit in front of a computer for work, try moving around and changing positions throughout the day.

If you’re waking up frequently with a stiff neck and shoulders, you may want
to reevaluate the position you sleep in most often. If you’re a side sleeper, for
example, your pillow should support your head so that your neck is in the
same line as your spine. If you consistently wake up with a stiff lower back,
you may also want to consider whether your mattress is the culprit. There
isn’t one universal mattress type that will cure all tightness, but experts
recommend different firmness levels depending on your needs.

If your joint stiffness lasts for longer than an hour after you’ve gotten out of
bed and persists for weeks or even months, you should consult with a health
care provider, Capetta said. Joint stiffness that lasts for an hour or longer
could be an early indicator of arthritis. You should also see a doctor if you
stretch regularly but still feel chronic tightness throughout the day.

Most of the time, morning tightness will naturally recede as you go about your
morning. “But everyone has a different threshold for what is bothersome,”
Capetta said. If it troubles you, some movement and stretching first thing in
the morning may be enough “to reduce the time or to reduce the impact of
this particular experience,” she said — whether it’s a universal one or not.
