Night shift workers who have trouble sleeping may have a condition known as shift work sleep disorder. âWorking non-traditional shifts interferes with the bodyâs circadian rhythms,â says sleep expert Tina Waters, MD. âMost of us are awake during the day because our bodyâs internal clock is keeping us awake.
Election to Congress in 1854 and the Mexican War brought the issue of the expansion of slave territory to the nation's attention. Lincoln formed a clearer position on slavery. He was opposed to black equality and had no intention of disturbing slavery in slave states.
In September 1862, Lincoln issued the Emancipation Proclamation, freeing all slaves in areas that were still in rebellion against the Union. This measure opened the issue of what to do about slavery in border states that had not seceded or in areas that had been captured by the Union before the proclamation. In 1864, an amendment abolishing slavery passed the U.S. Senate but died in the House as Democrats rallied in the name of statesâ rights.
