Thank you for watching and your questions. There are some buttons on the side of the fan to control the air flow as well as vents for the air to pass through. Also, it is USB cable charging. Which means how long or ever high you have the setting will determine how long the charge will last. Finally, it's not necessarily harmful to wear overnight, it just won't run the whole night, plus laying on it may obstruct the air vents. Reclining in a chair may work better. Hope this helps!
