Photons hit our eyes or bodies which activate a certain hormone which causes us to wake up. Does anyone know if the photons have to hit your eye or your body?
Not that I am aware of. There was a time that anti-jetlag devices were sold that were placed in the knee pit, but I'd be interested to know whether they really work. A clue comes from people who are blind, the publications I have seen report that they have free-running circadian periods.atyy said:http://www.sciencemag.org/content/279/5349/396.abstract (! has this been replicated?)

light, focused on the back of the eye, can be used to reset the internal clock and treat circadian rhythm disorders such as jet lag
There are several mechanisms that can wake someone up, including natural body rhythms, external stimuli, and alarm clocks. Natural body rhythms, such as the circadian rhythm, can cause you to naturally wake up at a certain time every day. External stimuli, such as noise or light, can also wake you up. And of course, the most common mechanism is the use of an alarm clock.
The circadian rhythm is the internal clock that regulates our sleep-wake cycle. It is influenced by daylight and darkness, and is responsible for making us feel sleepy at night and alert in the morning. When the circadian rhythm is disrupted, it can cause difficulty waking up in the morning.
Alarm clocks can have a negative impact on our sleep if they are used improperly. If an alarm goes off in the middle of a deep sleep cycle, it can disrupt the natural sleep process and make us feel groggy and unrested. It is important to set alarms for a time when our bodies are in a lighter stage of sleep.
The best way to wake up feeling refreshed is to get enough sleep and wake up naturally without an alarm. This allows our bodies to complete a full sleep cycle and wake up when the time is right for our individual circadian rhythm. If using an alarm, setting it for a time when we are in a lighter stage of sleep can also help us feel more refreshed.
Certain foods and drinks, such as caffeine, can provide a temporary boost of energy to help with waking up. However, it is important to not rely on these substances and to maintain a healthy sleep schedule to ensure proper rest and waking up feeling refreshed.
