Heating Pad or Ice Pack? When to Use Each

By Mark from Outback, The Outback Series customer care6 min read

The short answer

Ice is for something new: a fresh bump, twist or knock, or a spot that is swollen or bruised, especially in the first day or two. Use it for 10 to 15 minutes, never more than 20, with a cloth between the ice and your skin.
Heat is for something stiff: tight, tired muscles, morning stiffness, or shoulders that ache after a long drive. Use warm, not hot, for under 20 minutes, and never fall asleep on a heating pad.
Skip both on skin that does not feel normally, never put heat on a swollen or bruised spot, and never use a heating pad over a menthol or camphor rub.

The quick rule: new and puffy gets ice, old and stiff gets heat

Ice and heat do opposite jobs. Cold numbs the area and calms swelling, so it suits something that just happened. Warmth feels soothing on muscles that are tight and stiff.

What is going on	Use	Why
A fresh bump, twist or knock (first day or two)	Ice	Calms the swelling and numbs the spot
A spot that is swollen, puffy or bruised	Ice	Heat can make swelling worse
Stiff when you first get up	Heat	Warmth helps tight muscles loosen
Tight neck and shoulders after reading or driving	Heat	Feels soothing on muscles held in one position
A muscle knot or cramp	Heat	Helps the muscle let go
Sore the day after yard work or a long walk	Heat, or cold if a spot feels hot or puffy	Go by what the spot feels like

How to use an ice pack safely

Wrap it. Put a thin towel, cloth or paper towel between the ice and your skin. Never put ice straight on bare skin.
Set a timer for 10 to 15 minutes. Cleveland Clinic says that is usually enough, and not to go past 20. Go shorter on fingers, toes and other small areas.
Check your skin halfway. Stop if it turns white, very red or blotchy.
Give it a break. Let the skin warm back to normal before the next round. Several short rounds a day work better than one long one.

No ice pack? A bag of frozen peas molds around a knee or ankle. Label it so it never ends up on the dinner table.

How to use heat safely

Heat is where most of the trouble happens. Heat plus time is what burns skin, even from a pad that only feels warm. The University of Utah burn center reports heating pads are a top cause of burns in the older adults it sees, because older skin is thinner and slower to recover.

Warm, not hot. Start on the lowest setting that feels warm. If it ever feels uncomfortably hot, take it off.
Under 20 minutes at a time, then give your skin a rest.
Never fall asleep on a heating pad. Use one with an automatic shut-off, and keep it off the bed at night.
Rest it on you rather than lying on top of it, and never fold it or wrap it tight around a joint.
Moist heat counts too. A warm shower or bath is an easy option. Cleveland Clinic suggests water between 92 and 100°F (33 to 38°C).
Microwavable wraps: heat as the label directs and test on your inner wrist first.

Mark's tipMy rule of thumb for customers: if you would not hold your hand on it for 20 minutes, do not put your back on it for 20 minutes. And put the heating pad on a kitchen timer, not on your memory.

Who should skip heat or ice, or ask first

Skin that does not feel normally. If you have reduced feeling in your hands, feet or legs, you may not notice a burn or frostbite until it is too late. Ask your doctor before using either.
A medical condition that affects your circulation or how you sense hot and cold.
Swollen, bruised or broken skin: no heat, and never ice an open wound.
Someone who cannot move it away. Never leave a heating pad or ice pack on a parent who is asleep or cannot easily take it off.

Heat, ice and rubs: what not to mix

Menthol and camphor rubs and other medicated creams warn on the label: do not use them with a heating pad or wrap them tightly. Heat on top of a medicated rub raises the risk of skin burns. Use one or the other.

A simple routine that works: warmth first, from a warm shower or 15 minutes with a heating pad. Let your skin cool back to normal, then massage the tight spot for a minute or two.

Frequently asked questions

Should I use heat or ice for sore muscles?

For stiff, tight or tired muscles, heat usually feels best. For a fresh bump or twist, or a spot that is swollen or bruised, use ice. If a sore spot feels hot or puffy, choose cold.

How long should you leave an ice pack on?

About 10 to 15 minutes, and no more than 20, with a cloth between the ice and your skin. Let the skin warm back to normal before the next round.

Is it safe to sleep with a heating pad?

No. Even a warm pad can burn skin over several hours. Use it for under 20 minutes while you are awake, and choose one with an automatic shut-off.

Can I use heat and ice on the same spot?

Yes, in order: ice first for a fresh twist or bump, then gentle heat once the swelling has settled. Never both at once.

Can I put a muscle rub on and then use a heating pad?

No. Menthol, camphor and other medicated rubs warn against using a heating pad, because heat on top of the rub can burn the skin. Use one or the other.
