When you’re going to bed on time each evening and getting the required 7-9 hours’ sleep your body needs, you’d expect to wake up every morning refreshed, invigorated and ready to go. However, that is not always the case. Many people report getting enough sleep but still feeling exhausted all the time and barely able to get through the day.
Sleep is critical to the survival of the human body. The body just cannot continue to function if it does not get enough sleep. Sleep deprivation is often self-imposed by people who do not judge it necessary to get sufficient sleep. So, they get 4-5 hours’ sleep a night. Eventually, their bodies cannot go on anymore, and they are likely to fall ill.
During sleep, the body is healing any tissues, muscles and blood vessels. This includes the heart muscles and the blood vessels that supply it and muscles that were strained during the day’s activities or exercises. It is also critical to the maintenance of the body’s immune system which prevents us from being susceptible to opportunistic infections. The body is much like the battery of your cell phone. It cannot run indefinitely and needs to recharge. Whilst electricity charges your phone, sleep charges your body.
A lack of sleep can occur even though you get enough sleep. If you don’t get sufficient deep sleep or you wake several times during the night, you will always feel tired. Sleep deprivation leaves you irritable, depressed and drowsy all the time. It makes decision-making difficult. Your body also begins to crave starchy, unhealthy foods to give you a short-term energy boost to overcome your fatigue. Here are some reasons enough sleep still leaves you tired.
1. Tech addiction
Many people think that browsing the internet, looking at their social media accounts, or playing games on a cellphone, tablet or computer is the perfect way to relax and prepare their bodies for sleep. Others believe that the best way to fall asleep is watching TV shows. In fact, nothing could be further from the truth. At the University of Gothenburg, Sahlgrenska Academy 4,100 young people’s use of technology was studied to determine how it affected their sleep and mental health. Many reported problems with sleep together with symptoms of stress and depression.
Studies show that computers, tablets, and cellphones disrupt the body’s ability to sleep. Their high-resolution screens prevent the body from producing a sleep hormone called melatonin. Darkness is required to produce melatonin. A lack of melatonin causes a raised level of alertness which makes sleep difficult. Even though you may fall asleep easily enough, the quality of your sleep is affected by the melatonin in your body.
Experts believe that passive technology use such as watching television, listening to music, or reading an e-book doesn’t have as big an impact on the body’s sleep patterns as interactive applications such as playing games, surfing the web and posting on social media. So, it is advisable to cease all interactive technology use at least one hour prior to going to bed. Passive technology use can be used closer prior to turning off the lights.
Whilst the use of technology is inevitable in today’s world, it is preferable to put cellphones, computers, and tablets away in the evening well before bedtime. And if you’re going to bed on time and still waking up tired, don’t use any passive technology too close to bedtime either to see if it has an appreciable effect.
