The right sheets
Sheets make the biggest impact because your body stays in contact with them all night.
Linen
Linen stands out because of how efficiently it moves air and moisture. The fibres naturally create tiny gaps that let heat pass through instead of building up under your body. It absorbs moisture, releases it again quickly and doesn't cling, which helps on warm and humid nights.
Bamboo
Bamboo offers a smooth, cool surface. It handles humidity well and wicks away moisture; so, if you prefer a sleek, softer feel but still want breathability, bamboo is a great warm-weather option.
Cotton percale
Percale appeals to people who like classic cotton but want something that stays fresh. The lightweight weave gives it a crisp texture without the warmth associated with denser cotton styles.
Fabrics worth avoiding
Microfibre, sateen and anything with a very high thread count tend to feel dense and hold on to heat. They may feel smooth at first touch, but they work against you once you're settled in bed.
Quilts and doonas
Your quilt/doona has a bigger impact on temperature than many realise. Look out for the 'GSM' rating. GSM stands for 'grams per square metre' -- the lower the GSM, generally the lighter the quilt will be.
Cotton summer quilts
Cotton works well because it absorbs moisture and disperses it rather than trapping it near your skin. Low-GSM cotton quilts feel light, settle comfortably on your body without adding weight.
Bamboo quilts
Bamboo-filled quilts breathe extremely well and continue to move heat even when nights stay warm. They drape softly and suit people who dislike the more structured feel of traditional quilts/doonas.
Lightweight wool quilts
Low-GSM wool handles warm conditions better than expected, rapidly removing moisture and stabilising temperature.
Ultra-light down
Warm-climate down quilts use minimal fill, which keeps them light and airy. They give you a soft feel without the warmth associated with winter doonas.
How to spot a genuine summer quilt
- Low GSM or a tog rating around 1.5 - 4.5
- Natural fibres
- Cotton outer fabric
- Simple stitching rather than thick, raised patterns
Avoid bulky polyester fills and all-season doonas if you know you heat up easily.
Pillows
Heat gathers around your head faster than you might expect, so a breathable pillow makes a noticeable difference.
Latex
Latex pillows allow heat to disperse through their open structure. They stay cooler than dense memory foam and keep their shape without holding onto warmth.
Feather and down
These fills are naturally breathable. Air moves freely inside the pillow, which reduces the warm, damp feeling that can build during hot nights. A cotton protector keeps humidity down without blocking airflow.
Cooling foam
If foam is your preference, choose versions with ventilation channels or gel layers. These are specifically designed to help air move and prevent heat from building up.
What to skip
Solid memory foam without ventilation and protectors with plastic coatings create warm, clammy surfaces.
Small details:
- Lower thread counts allow better airflow
- Light colours absorb less heat
- Well-fitted sheets lie smoothly and don't trap warm pockets of air
