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 office March 1861 - April 1865. Lincoln joined the Republican Party in 1856 and opposed the extension of slavery into new territories, though he could not see a way of abolishing it. His election as president precipitated the American Civil War. Lincolnâs aim was to preserve the Union, not to end slavery, which he made clear in his Gettysburg Address. However, as the war turned in the Unionâs favor in 1863 he proposed in his Emancipation Proclamation to free all slaves after the war.
