Exodus 20: 8-11 " Remember the sabbath day to keep it holy. Six days shalt thou labor, and do all thy work: But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger, which is in thy gates: For in six days the Lord made the heaven and earth , the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day , and hallowed it."
Our bodies need rest. We should get about 7 to 8 hours of sleep per day, and too much sleep increases the risk of many common diseases, so don't sleep too much!
