Getting a lot of sunlight in the morning is also a good way to reduce jetlag by resetting your circadian rhythm to be in sync with your new time zone.

If you live in a climate where you do not have access to sufficient sunlight, one possible alternative is to buy an LED corn bulb (don't use it too late at night, otherwise you won't be able to fall asleep):

You can buy these fairly inexpensively from retailers like AliExpress if you are ok with waiting a month for shipping from China: https://www.aliexpress.com/wholesale?SearchText=corn+bulb

If you live in North America, Japan, Korea, or Taiwan (120V AC), you want an E26 socket lamp, otherwise for 240V AC grids, you should consider E27 socket lamps.
