For those of us in the Southern Hemisphere, winter arrives just as the rest of the world is firing up their barbecues. While our friends in the north are posting beach selfies, we’re reaching for the extra blanket. But staying warm doesn’t have to mean sky-high energy bills or shivering through to September. Here’s your practical guide to keeping the cold at bay this winter.

1. Layer Up — and Do It Smart

The golden rule of winter dressing is layers, but there’s an art to it. Start with a moisture-wicking base layer (merino wool is outstanding for this — it regulates temperature and doesn’t hold odour), add an insulating mid-layer like a fleece or down vest, and finish with a wind and water-resistant outer shell.

The same principle applies at home. A lightweight thermal undershirt worn around the house can reduce your reliance on heating significantly. It sounds simple, but it’s genuinely one of the most effective strategies going.

2. Draught-Proof Your Home

Up to 25% of heat loss in a typical home occurs through gaps around doors, windows, and floorboards. Fixing draughts is one of the cheapest and most impactful things you can do before the cold really sets in.

• Use door snakes or draught excluders at the base of external doors
• Check window seals and replace cracked or missing weatherstripping
• Seal gaps around skirting boards and floorboards with appropriate filler
• Don’t forget the chimney — a chimney balloon or flue blocker prevents huge amounts of warm air escaping when your fireplace isn’t in use

Many hardware stores stock draught-proofing kits for under $20 that can make a surprising difference almost immediately.

3. Maximise Your Heating Efficiency

If you use a reverse-cycle air conditioner or a heat pump, set it to around 18–20°C rather than cranking it higher. Every degree above 20°C can add roughly 10% to your heating costs. Close doors to rooms you’re not using so you’re only heating the space you’re actually in.

For those with gas heaters or wood fires, make sure they’re serviced before the season starts. An inefficient heater works harder, costs more, and can pose a safety risk. And always ensure adequate ventilation — never use unflued gas heaters in enclosed spaces.

4. Warm Your Bed Before You Get In

There’s nothing quite like sliding into a cold bed on a winter night — and not in a good way. A hot water bottle placed under the covers 15–20 minutes before bedtime is a time-honoured solution that costs next to nothing to run. Electric blankets are another excellent option; use them to pre-warm the bed, then turn them off before you fall asleep.

Flannel or brushed cotton sheets feel dramatically warmer than standard cotton at the same temperature, and a quality doona rated for winter conditions will outperform a pile of lightweight duvets.

5. Eat and Drink Warm

Your body generates heat through digestion, so lean into it. Winter is the perfect excuse for soups, stews, curries, porridge, and slow-cooked meals — all of which warm you from the inside out. Spices like ginger, chilli, and cinnamon are genuinely thermogenic, meaning they help raise your core body temperature.

Keep a thermos of herbal tea or warm water nearby during the day. Staying hydrated is just as important in winter as summer — and a warm drink is both comforting and practical.

6. Get Moving

Physical activity is one of the most immediate ways to warm up. Even a 10-minute walk, some gentle stretching, or a few household tasks can raise your body temperature noticeably. If you work from home, make a point of getting up regularly — sitting still for long periods lets your body cool down faster.

Cold-weather exercise outdoors is perfectly safe and actually quite invigorating once you’re dressed appropriately. The key is keeping your extremities — hands, ears, and feet — covered, as these are where heat loss is greatest.

7. Use Your Curtains Strategically

Thick, lined curtains are a winter essential. During the day, open curtains on north-facing windows (in the Southern Hemisphere, north-facing windows receive the most winter sun) to let in passive solar warmth. As soon as the sun drops, close them to trap the heat inside. This one habit alone can reduce heat loss through windows by up to 40%.

If you don’t want to invest in new curtains, a temporary fix is to add a thermal lining to your existing ones — these are available from most fabric and homewares stores.

8. Don’t Forget the Floors

Cold floors account for more discomfort than most people realise, particularly in homes with tiles or floorboards. A good rug over a cold floor makes a room feel warmer immediately — and actually helps insulate the space. Pair this with a warm pair of slippers and you’ll wonder why you ever went without.

Q&A: Your Winter Warmth Questions Answered

Q: Is it better to keep the heating on low all day or heat the house in bursts?

A: For most homes, heating in bursts when you actually need warmth is more energy-efficient than maintaining a constant low temperature. However, if you’re home all day or have young children or elderly family members who feel the cold acutely, a steady low temperature around 18°C may be more practical and comfortable.

Q: My home doesn’t have insulation — what’s the most cost-effective fix?

A: Ceiling insulation gives you the best return on investment of any home improvement for warmth, as heat rises and escapes through the roof first. If you’re renting, talk to your landlord — in several Australian states and New Zealand, minimum insulation standards are now part of rental regulations. In the meantime, focus on draught-proofing and heavy curtains for immediate gains.

Q: Are electric blankets safe to leave on overnight?

A: Modern electric blankets with automatic shut-off features are much safer than older models, but the general advice is still to use them to pre-warm your bed and then switch them off before sleeping. Never fold an electric blanket while it’s on, and replace any blanket that shows signs of wear, fraying, or damage.

Q: What’s the best indoor temperature for staying healthy in winter?

A: Health authorities generally recommend keeping living areas at a minimum of 18°C, particularly for households with young children, the elderly, or anyone with a respiratory condition. Cooler bedrooms (around 16–18°C) are actually associated with better sleep, so you don’t necessarily need to heat your bedroom to the same level as your living spaces.

Q: Any tips for renters who can’t make structural changes?

A: Absolutely. Focus on what you can control: heavy curtains, rugs, draught snakes, warm bedding, and layering your clothing. A portable oil-column heater is an efficient option for renters as it heats a room gently and retains warmth well. And don’t underestimate the power of a good hot water bottle — cheap, effective, and completely renter-friendly.

Winter in the Southern Hemisphere may arrive quietly — no snowstorms or frozen pipes for most of us — but a damp, grey July can feel just as relentless. A few of these habits combined will make a genuine difference, both to your comfort and your power bill. Stay warm out there.
