• People who have shallow sleep and can't sleep well once there is light;
• Children. Because children's height growth usually occurs during sleep, and they are more likely to enter deep sleep in dark conditions. Medical studies have shown that growth in children during sleep is affected by light, so even if you don't buy blackout curtains, you should never install night lights in children's rooms.

The principle of blackout curtains

The principle of blackout curtains is divided into chemical blackout and physical blackout. Chemical blackout involves adding a coating to the hanging layer of the curtain, which may involve the use of glue and emit a stimulating odor. Physical blackout involves either weaving a layer of black silk between two layers of fabric or using blackout lining in matching colors sewn inside the curtain. In principle, physically blackout curtains are safer, but they may be more expensive in price.

The hanging style of blackout curtains significantly influences their effectiveness in blocking light. For optimal results, opt for french pleat/tailored pleat or rod pocket.These styles ensure minimal light leakage, unlike tab top or hanging rings, which may permit light to enter, especially if the curtain rod isn't mounted well above the window.

This curtain utilizes physical blackout technology, weaving a layer of black silk between two layers of fabric. Both sides feature the same fabric, ensuring a uniform appearance even when viewed from outside the window, avoiding any awkward inconsistency in texture and color. Additionally, this curtain comes in 10 different colors, allowing you to choose a matching color according to your bedroom's decor style. Linen curtains, with their unique texture, emit a relaxed atmosphere, making them perfect for creating a tranquil ambiance in the bedroom.
