The Main Causes of Sleep issues : Stress and Technology

Stress – it releases cortisol, the “stress hormone” and if its levels are high, then restful sleep will be prevented, interfering with your feelings and well-being.

Technology – When is time to sleep our brain automatically sends us signals(melatonin). the light emitted by the devices prevents the brain release the amount of melatonin needed for the body. If we stay in the dark, the body releases more melatonin, and this process is interrupted by the light emitted by our TVs, laptops, and cell phones.
