How Weighted Blankets Create That Comforting Pressure
If you have ever slept under a weighted blanket, you will know the feeling - a gentle, even pressure across your body that feels a bit like being held. It is surprisingly effective at calming a restless nervous system, and the reason comes down to how the blanket is built.
Weighted blankets work on the principle of deep pressure stimulation (DPS). This is the same idea behind a firm hug or a swaddled baby - steady, distributed pressure that signals to your body that it is safe to relax. Research suggests DPS can reduce cortisol levels and increase serotonin production, which helps explain why many people find weighted blankets useful for managing anxiety at bedtime.
What Is Actually Inside the Blanket
The Bead Layer
The weight in a weighted blanket comes from small beads sewn into individual pockets across the inner layer. The pocket design is important - it stops the beads from pooling in one corner and ensures the weight is distributed evenly across your body. Without this structure, the blanket would feel lumpy and unbalanced rather than soothing.
There are several types of beads used in manufacturing, and the choice affects how the blanket feels, how heavy it is, and how well it breathes.
Glass Micro-Beads
These are the most common fill in quality weighted blankets. Glass micro-beads are tiny, smooth, and dense, which means the blanket can be heavy without being bulky. They also tend to feel cooler against the skin than plastic alternatives - a real consideration if you sleep warm or live somewhere humid.
Plastic Poly Pellets
Plastic pellets are larger and lighter than glass beads, so blankets filled with them tend to be thicker. They are durable and affordable, but they can trap more heat and feel less refined. If breathability matters to you, glass beads are generally the better option.
Steel Shot Beads
Less common but worth mentioning, steel shot beads are extremely dense and allow for very thin, heavy blankets. They are typically found in premium products and offer excellent weight-to-bulk ratio. The trade-off is cost - steel shot blankets tend to be significantly more expensive.
The Outer Layers
Most weighted blankets use a polyester or cotton outer shell. Cotton breathes better and is generally more comfortable for direct skin contact, while polyester shells are more durable and easier to clean. Some blankets come with a removable duvet-style cover, which makes washing much easier - the weighted inner layer can be difficult to fit in a standard washing machine.
The stitching pattern matters too. Smaller pockets (usually around 10 to 15 centimetres square) keep the beads more evenly distributed than larger ones. If you are considering a weighted blanket, look for tight, consistent stitching and a pocket pattern that covers the full surface of the blanket rather than just the centre.
Choosing the Right Weight
The general guideline is to choose a blanket that weighs roughly 10 percent of your body weight. So if you weigh 70 kilograms, a 7-kilogram blanket is a good starting point. Going too heavy can feel restrictive rather than comforting, and too light will not deliver enough pressure to trigger the deep pressure response.
It is worth noting that weighted blankets are not suitable for very young children or anyone who might have difficulty removing the blanket independently. If you are unsure, it is always worth checking with a healthcare professional first.
Other Ways to Create That Calming Pressure at Night
If a weighted blanket is not quite right for you, there are other approaches to creating a sense of calm and containment at bedtime. Gentle compression clothing, a firm pillow arrangement, or simply layering heavier bedding can produce a similar effect. Many people also find that pairing physical comfort with calming pulse technology helps them settle more quickly.

"I bought a weighted blanket after years of restless sleep and the difference was immediate. Knowing what is inside it helped me choose a quality one - the glass bead version is so much nicer than the plastic pellet one I tried first."
