Weighted products calm the body's senses. You can compare it somewhat to a hug from a friend or to massage therapy, both of which have a relaxing effect on muscle tension. Professionally, the technique is called DPS (“deep pressure stimulation”) (1, 2). We can also refer to it as pressure treatment. The healthcare system, physiotherapists, and other health professionals can advantageously use weighted products as part of pressure treatment, as the products' weight modulates the body's sensory impressions.
When a nerve in the skin is subjected to strong and persistent pressure from the outside, oxytocin is released. Oxytocin is a hormone that minimises the body's stress symptoms and strengthens the immune system. The hormone also regulates the serotonergic system, which, among other things, controls blood pressure, motor skills, and affective behaviour by releasing serotonin (3).
The rule of thumb is ~10% of a person's body weight.
Researchers have primarily studied weighted products with regard to safety considerations and comfort. Currently, there are no studies that have found direct safety risks associated with the rule of thumb. On the contrary, several studies emphasise that there are significant benefits to the rule. For example, a well-known 2008 study found that weighted blankets weighing 13 kg had a calming and anxiety-reducing effect when evenly distributed across the body. The participants were healthy adults with a median weight of 74 kg (1).
Whatever a weighted product weighs, a person should be able to move it comfortably when using it.
Zibocare’s range of weighted blankets spans 4-12 kg, so that one can find a suitable blanket without much hassle. See the range here.
Weighted blankets can improve one's sleep quality, which can enhance one's quality of life (QoL). QoL is a typical index measure in the medical world.
It is believed that approximately 30% of the population has sleep difficulties (4). Poor sleep quality is associated with depression, stress, psychosomatic disorders, cardiovascular and metabolic problems, and much more (4). Research shows that weighted blankets are beneficial for health in these areas. For example:
Weighted blankets can therefore help treat sleep disorders and other related health issues, without increasing costs for the healthcare system – on the contrary.
