Who can refuse a warm quilt in winter, especially lying in a freshly sunburned, fluffy cotton quilt, heavy weight, sealing a person on the bed, even with some mixed thoughts are also suppressed, a good night's dream.
Why is it better to sleep than the new duvet, silk quilt, or cotton quilt in the hometown, is it because of the blessing of childhood memory buff? The secret is the weight – the heavier the quilt, the more you sleep.
Researchers from the Karolinska Institutet in Sweden found that falling asleep on a blanket (6-8 kg) significantly improved sleep in just one month, cured most insomnia patients within a year, and reduced symptoms of depression and anxiety, the study was published in the journal Journal of Clinical Sleep Medicine, a subsidiary of the American Society of Sleep Medicine.
Insomnia is mainly manifested by difficulty falling asleep or maintaining sleep, and affects normal activities during the day, patients usually feel tired, emotionally showing anxiety and depression.
As one of the most common psychiatric disorders, 30%-48% of adults have symptoms of insomnia, 6% meet the diagnostic criteria for insomnia, especially in psychotic patients, insomnia occurs more frequently - 70% of patients with bipolar disorder and 60% of people with anxiety and depression are deeply affected by insomnia.
A total of 120 patients with insomnia for more than 2 months with any of the following psychiatric disorders including: major depression, bipolar disorder, anxiety disorder, or hyperactivity disorder were included in the study.
Participants were randomly assigned to two groups in a 1:1 ratio, one with a heavy blanket cover, 6-8 kg (when participants felt that 8 kg was too heavy, it could be exchanged for a 6 kg blanket), and a group covered with a light blanket weight of 1.5 kg as a control group.
The main study results were the improvement of sleep conditions, with insomnia severity index as the evaluation index, secondary study results as daytime function improvement, fatigue scale, hospital anxiety, depression scale as evaluation indicators, and combined with the participants' day and night self-assessment records and wrist activity recorders to assess the participants' sleep and daytime activity levels.
The results showed that after 4 weeks, the effective rate of insomnia improvement was 59.4% (insomnia severity index decreased by more than 50%), the complete response rate was 42.2% (no clinically significant insomnia), while the insomnia improvement rate of participants using light blankets was only 5.4%, and the complete response rate was only 3.6%.

Wrist activity recorders also showed that the use of heavy blankets improved participants' ability to maintain sleep, and while insomnia symptoms improved, participants also experienced positive changes in daytime function: increased daytime activity, longer concentration, and shorter rest.

Not only that, compared with the control group, the participants who used heavy blankets had symptoms of daytime fatigue, anxiety, and depression.
After the end of the 4-week experiment, 112 participants went on to participate in a one-year heavy blanket use experiment, and after one year, all participants had a 92% effective rate for insomnia improvement and a complete response rate of 78%.
This study demonstrated that the weight of the quilt had a significant effect on the improvement of insomnia symptoms, especially for patients with psychiatric disorders with severe insomnia, and the heavy blanket not only reduced the severity of insomnia in patients, but also alleviated the symptoms of fatigue, anxiety and depression in the participants during the day.
As for why heavy blankets have the effect of promoting sleep, researchers Dr. Mats Alder believe that the pressure exerted by heavy blankets on the body stimulates deep touch and muscle and joint sensations, which has an effect similar to acupressure and massage. Secondly, studies have shown that deep pressure stimulation can arouse the parasympathetic excitement of the autonomic nervous system, inhibit sympathetic excitement, and produce a sedative effect. Finally, deep stress stimulation is able to increase the body's secretion of oxytocin, which has an anxiolytic and sedative effects and plays an important role in the sleep and relaxation process.
So, if mental stress makes you toss and turn in the middle of the night, try to pressurize your body (it turns out that the quilt is not the grave of youth, but the harbor of the soul, plunging into the quilt).
