Look around your bedroom, and it is likely that you will see a wide assortment of technology, such as a television, cell phone, computer, or tablet. All of these devices can be incredibly convenient and fun, but technology can actually have a negative effect on your sleep. The more gadgets you have in your room, the more disrupted your sleep is likely to be. A lack of sleep can cause an increased risk for cardiovascular disease, obesity, and diabetes, as well as exacerbate existing issues such as depression and anxiety, and increase feelings of stress. Because of this, it is pivotal to get all those devices out of your room if you would like to get a good night’s sleep.
If you’re having trouble sleeping, you might need a little boost to get your rhythm aligned with the cycles of nature. For instance, there’s a reason why we sleep at night when it’s dark and wake during the day when it’s light. In recent years, scientists have been studying the alternating cycle of sleep and waking and how that is related the hours of daylight and darkness.
It turns out that when an individual is exposed to the sunlight, a nerve pathway from the retina to an area in the brain is stimulated, and this initiates the release of certain hormones, which influence body temperature and other functions that play a role in feeling awake. This area of the brain works like a clock and regulates patterns of activities such as raising body temperature and releasing hormones like cortisol. Later in the day, this area of the brain is also responsible for the release of melatonin, which is related to functions of the body which bring on the need to sleep.
