Quick Answer Why do I wake up earlier when daylight saving ends? What curtains stop early morning sunlight best? Are blockout blinds good for bedrooms? Do blockout curtains completely block sunlight? How does sunlight affect sleep? |
When daylight saving ends, many homeowners notice an unexpected change in their sleep routine. The sun begins rising earlier in the morning, which means bedrooms can suddenly feel much brighter at the start of the day.
If sunlight enters your room before your alarm goes off, it can trigger your body to wake up earlier than usual. Fortunately, the right window furnishings can make a big difference. Well-designed curtains and blinds allow you to control light levels, improve privacy, and create a more comfortable bedroom environment.
At Curtain Studio, we help homeowners choose curtains and blinds that combine style, functionality, and light control. If early morning sunlight is disturbing your sleep, there are several practical solutions that can help keep your bedroom darker for longer.
How to Stop Early Morning Sunlight from Waking You Up
The most effective way to stop early morning sunlight waking you up is by installing window furnishings designed for strong light control, such as blockout curtains or blockout roller blinds.
These products are specifically designed to reduce incoming sunlight and create a darker bedroom environment even when the sun rises earlier.
Quick ways to reduce early morning sunlight in your bedroom:
- Install blockout curtains
- Choose blockout roller blinds
- Layer curtains with blinds for extra coverage
- Install curtains wider and higher than the window frame
- Use motorised blinds that close automatically at night
Improving light control around your windows can help maintain a consistent sleep environment throughout seasonal changes like daylight saving.
Why Bedrooms Feel Brighter When Daylight Saving Ends
In New Zealand, the end of daylight saving shifts the clock back by one hour. While evenings become darker earlier, the sun also rises earlier in the morning.
For homes with east-facing windows or large bedroom windows, this can mean significantly more sunlight entering the room at the start of the day.
Even small amounts of light can signal to your brain that it is time to wake up. Light exposure reduces melatonin production, which can shorten sleep duration and make it harder to stay asleep.
This is why improving light control in the bedroom can help maintain better sleep quality throughout seasonal changes.
Best Window Furnishings for Blocking Morning Sunlight
Different window furnishings offer different levels of light control. Choosing the right option depends on your bedroom layout, window size, and personal preferences.
Blockout Curtains
Blockout curtains block the most sunlight and are one of the most effective solutions for darker bedrooms.
These curtains use dense fabrics or specialised linings designed to prevent light from passing through the material. When properly installed, blockout curtains can block most incoming light, making them ideal for bedrooms and nurseries.
Benefits include:
- Excellent light blocking
- Improved sleep quality
- Better insulation and temperature control
- Added privacy

At Curtain Studio, we offer a wide range of blockout ready-made curtains as well as custom-made curtains in a variety of blockout fabrics, allowing you to choose a solution that suits your bedroom, style, and light control needs.
If you already love your current curtains or are looking for a more affordable way to improve light control, attachable blockout lining is another great option. This popular solution can be added to existing curtains to help reduce incoming light and improve comfort in your bedroom.
Blockout Roller Blinds
Blockout roller blinds are another popular option for controlling early morning sunlight.
These blinds sit close to the window frame and use specially designed fabrics to reduce incoming light. Their simple design makes them a great choice for modern homes or minimalist interiors.
Roller blinds are often chosen because they are:
- Easy to operate
- Compact and modern in appearance
They are particularly effective for bedrooms where homeowners want strong light control without bulky window coverings.
At Curtain Studio, we offer both readymade blockout roller blinds as well as custom-made blockout roller blinds, giving you flexibility to choose a solution that suits your window size, style, and level of light control.

Fabric and Material Considerations
Not all curtains provide the same level of light control. Fabric choice plays a major role in how much sunlight enters the room.
Blockout curtains typically include a thick coated backing, which significantly reduces incoming light while also helping to reduce heat loss, reflect sunlight, and soften external noise for added comfort and privacy.
When choosing curtains, consider:
- Fabric thickness – thicker fabrics block more light
- Curtain lining – blockout linings improve light control
- Curtain width – wider curtains reduce light gaps
- Installation – properly fitted curtains improve performance

- Choose neutral blockout curtains for a calm and relaxing atmosphere.
- Combine sheer curtains with blockout curtains to allow flexible light control throughout the day.
- Install motorised blinds for convenient opening and closing.
- Select fabrics and colours that complement your bedding and interior design.
