Why your joints hurt more in winter (and the Kiwi botanicals that help)

As the crisp winter air settles across New Zealand, many of us over the age of 55 notice a familiar yet unwelcome shift in our bodies - fingers feeling stiffer while opening jars in the morning, knees aching on the stairs, or old injuries suddenly making themselves known again.

It’s incredibly common to feel like your joints can predict a cold snap or an incoming storm. And for years, this connection between weather and joint pain was dismissed as an old wives’ tale. But modern research now shows there are very real physiological reasons why colder weather can increase stiffness, tension, and discomfort within the body.

Understanding exactly why the winter cold causes your joints to tighten up is the first step toward managing it. By looking at how barometric pressure changes our bodies, and turning to powerful native New Zealand botanicals, you can keep your joints moving smoothly and comfortably all winter long.

Why do joints hurt more in winter?

Cold weather affects circulation and muscle tension

When temperatures drop, blood vessels naturally constrict to preserve body heat.

This reduced circulation can leave muscles feeling tighter and joints feeling stiffer - particularly first thing in the morning, when the body has been still overnight.

Cold weather also causes muscles and connective tissues to become less elastic, meaning the body can feel slower, tighter, and more uncomfortable moving through everyday activities.

For women already navigating hormonal shifts, inflammation, or magnesium depletion, winter can amplify those aches even further.

Changes in barometric pressure can increase joint sensitivity

Barometric pressure refers to the weight of the air around us. When pressure drops during colder, wet weather systems, tissues within the body can subtly expand. This creates additional pressure inside already sensitive joints, which may increase discomfort and stiffness.

At the same time, colder weather often means we move less, tense our muscles more, and spend longer periods sitting indoors - all of which can compound joint discomfort.

The power of nature

Nature offers some incredibly soothing plant remedies that have traditionally been used to comfort tired muscles and stiff joints - including three powerful ingredients featured within our range.

Magnesium: The ultimate muscle relaxant

Magnesium is the foundational powerhouse of our formula. When applied topically, transdermal magnesium absorbs directly into the tight tissues surrounding your joints. It acts as a natural calcium blocker, helping muscles to fully relax and halting the painful contractions and spasms that winter cold can trigger. Because cold weather depletes our body's resources faster, replenishing your magnesium locally is essential for unlocking stiff, frozen joints.

Capsaicin: The thermal pain blocker

Derived from chilli peppers, Capsaicin is a powerful, scientifically studied natural analgesic. When applied to the skin, it creates a gentle warming sensation that encourages blood flow back into cold, stiff areas.

Capsaicin also works on a neurological level by reducing Substance P - the neurotransmitter responsible for carrying pain signals to the brain. In simple terms, it helps turn down the volume on ongoing joint discomfort while simultaneously bringing comforting warmth to the area.

Kawakawa: New Zealand’s native soother

While capsaicin provides the active warmth, native New Zealand Kawakawa (Macropiper excelsum) provides deep, comforting anti-inflammatory relief.

Long valued within traditional Rongoā Māori practices, Kawakawa contains naturally soothing plant compounds that help calm irritated tissues, support circulation, and ease inflammation within tired muscles and joints.

Together, Capsaicin and Kawakawa create a powerful winter support duo - one warming and awakening the area, the other deeply calming and comforting it.

Your 3-step cold-weather morning ritual for easier movement

Winter stiffness is at its absolute worst first thing in the morning, when joints and connective tissues have cooled and tightened after hours of immobility.

To break that morning freeze, you need to deliberately reintroduce heat and circulation before you tackle your day. Our Joint & Muscle Cream was specifically formulated for this, combining therapeutic Magnesium with warming Capsaicin and soothing Kawakawa.

Here is how to turn it into a comforting, highly effective morning ritual:

1. The pre-warm

Wake up and do a few gentle, slow stretches while still under the covers to gently wake up your muscles.

Why it works: Raises your initial body temperature and prepares tissues for application.

2. The targeted massage

Before getting dressed, apply a generous amount of cream to your stiffest areas (knees, hands, hips, or lower back). Massage firmly in circular motions.

Why it works: The cream delivers transdermal magnesium straight to the tight tissue to halt muscle contractions, while the capsaicin interacts with local heat receptors to dilate blood vessels, instantly rushing warm, oxygenated blood directly into the stiff joint capsule.

3. Layer-up

Immediately wash your hands with warm, soapy water, then put on warm clothing (like thick socks or a soft sleeve) over the treated joints.

Why it works: Traps the natural, radiating heat generated by the cream, maximising your relief.

Within 10 to 15 minutes of application, you will notice a gentle, deeply comforting warmth begin to radiate from within the joint. This isn't just a surface sensation - it’s a sign that blood vessels are opening up, bringing healing oxygen to the area, thinning out sluggish joint fluids, and making movement feel smoother and freer.

Supporting your body through winter

It is incredibly easy to fall into a sedentary trap during winter because moving hurts. However, resting too much actually worsens joint stiffness over time. Joints rely on gentle movement to stay healthy and lubricated.

By supporting your body from the outside in with the targeted warming relief of New Zealand botanicals, you can break the winter cycle of pain and inactivity. You don't have to dread the arrival of a cold front. With the right morning routine, you can keep your joints feeling warm, flexible, and ready for whatever the day brings.

Don't let the winter chill slow you down. Bring deep, natural warmth back to your body with our fast-acting our Joint & Muscle Cream today.
