Swiss researchers discover sleep "switches" in the brain

Release date: 2018-06-14

Modern people's sleep time is about 20% shorter than 50 years ago, and many people suffer from chronic insomnia. In addition, lack of sleep can lead to various mental illnesses and decreased immunity. "Swiss News" reported on June 12 that researchers at the University of Bern recently discovered that sleep is regulated by the only control center in the brain.

So far, general cognition suggests that different regions of the brain control the rhythm of falling asleep and awakening. This new discovery in Switzerland is important for the treatment of insomnia and other complications caused by sleep.

Researchers at the University of Bern found that nerve cells in the thalamus control the function of falling asleep and waking up. The thalamus is closely related to all other areas of the brain, not only controlling human attention, self-confidence and perception, but also playing a "switch" role in sleep.

The Swiss research team used a genetic technique to control the nerve cells in the mouse thalamus with light pulses. When they use continuous pulses, the mouse wakes up; slow, rhythmic pulses make the mouse sleep deeper and calmer.

This new discovery was published in the journal Nature Neuroscience.

Whether you're heading back to the gym after the easing of pandemic restrictions or you're continuing to invest in home exercise equipment, online classes or fitness subscriptions, it's a good opportunity to make sure that you have the best tools for muscle recovery in your arsenal to help you reach your fitness goals. To achieve true workout recovery, you'll need a blend of nutrition and physical manipulation, but you can also take advantage of high-tech recovery tools meant to minimize muscle soreness (including the hard-to-resist CBD-infused activewear). If you're looking for a workout tool with science on its side, consider a Massage Gun.

Massage guns use the force of percussive therapy to manipulate your body's soft tissue. They're essentially backed by the same extensive scientific research that supports massage therapy as the optimal tool for sore muscles after a workout. Everyone from recreational gym-goers to professional athletes and people with chronic pain -- they all love these powerful massagers for many reasons.

Percussive therapy is said to help muscles recover faster while reducing muscle pain, muscle fatigue and lactic acid buildup. A percussion gun allows you to focus on a certain muscle group for immediate pain relief. They can also improve your range of motion and flexibility, encourage blood flow, help with muscle stiffness and more. Percussive therapy may even help with stress and sleep. Also, not that you should invest in one for this reason alone, but the slow-motion videos of massage guns punching muscles look insanely Insta-worthy. Just be careful with using one if you have any injuries beyond a muscle ache from a tough workout.
