Neurodermatitis is a skin condition that starts with a patch of itchy skin. Scratching makes it even itchier. This itch-scratch cycle causes the affected skin to become thick and leathery. You may develop several itchy spots, typically on the neck, wrist, forearm, thigh or ankle. Neurodermatitis â also known as lichen simplex chronicus â is not life-threatening or contagious. But the itching can be so intense or recurrent that it disrupts your sleep, sexual function and quality of life. Breaking the itch-scratch cycle of neurodermatitis is challenging. Treatment success depends on resisting the urge to rub or scratch the affected areas.
WHAT IS THE AURORA BOREALIS? The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earthâs atmosphere and collide with gases such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern and southern hemispheres.
Which layer of the atmosphere are the ionized particles that cause the aurora borealis? Aurora borealis occurs in the layer of the atmosphere called the  Thermosphere. Ionized particles from the sun are drawn to the  magnetic poles of Earth, which gives us the â¦spectacular Northern  Lights.
