It's essential to get some
rest when you're tired and get to sleep early if you must maintain a high energy level throughout the day. Before going to bed, clear your mind of every thought that may still be lingering in there. Improve your sleep area and keep it clean. Buy a comfortable mattress and duvet cover that will make you want to sleep all night long.
If possible, put your phone on silent or on airplane mode to avoid light and noise disruptions from your phone at night. Cover up any lights in the room or wear a sleeping mask. If you do wake up, avoid the urge to turn on the TV as this will likely make you more awake. Instead, try putting on some relaxing sounds such as white noise that can help lull you back to sleep.
If your sleep routine does not improve after some time, consult your doctor for immediate help.
