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.
How the Aurora Borealis Form. It begins with a solar flare. The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions result in countless little bursts of light, called photons, which make up the aurora.
