Cenli helps you from stress to rest by measuring temperature and tension

How is finger temperature related to stress?

Have you ever noticed that your hands and feet get warmer when you calm down? It’s actually a sign that your body is starting to let go of stress. When you go from a state of tension to rest, something often happens in the nervous system: the sympathetic stress system quiets down, and the body shifts to a more relaxed state. This allows the blood vessels in the skin to open up – which improves blood circulation to the hands and feet. You can therefore feel that your skin gets warmer, and the temperature in, for example, your fingertips can approach the body’s internal temperature of around 37 degrees. This is a natural sign that the body is regulating itself and finding balance.

We developed Cenli precisely to support this natural transition from stress to rest. This way you can more easily find peace, recovery and well-being in your everyday life.

What does neck tension have to do with stress?

The trapezius muscle, which runs from the back of the head down between the shoulder blades, is one of the most important muscles in the neck and upper back. It is used to lift the shoulders, move the head, and keep the upper body stable. When we are stressed, our bodies often react by tensing muscles—especially in the neck and shoulders. This happens automatically, as part of the body’s “fight or flight” response. Over time, tension can become chronic, especially if you have a sedentary job, poor posture, or rarely take breaks. Many people don’t notice it until they get a headache, stiff neck, or pain between the shoulder blades. Learning to relax these muscles, such as through breathing techniques or biofeedback, can reduce both tension and stress levels.

Cenli helps you connect with your trapezius and release tension, allowing your body to lower your shoulders – for real.
