Sleep does a lot to improve our overall health. It allows our brain to repair as well as other vital organs in our body. During sleep chemicals that help improve our immune system start to circulate in our bodies helping repair and fight harmful disease and infection.
Many factors contribute to women needing more sleep. Some say women tend to multitask more than men, causing them to need to use their brains more. Others say the chemical make up of a women's body just requires more sleep to function properly. Women are the only ones that can bring life into this world, so that could be evidence there.
On average women need at least 20 minutes more of sleep than men.
