If you're always tired, you're not alone. According to some data, 40 percent of adults say that fatigue interferes with their daily activities at least three days a week.
Why are so many people tired during the day?
Fox News Digital spoke with several sleep experts about the most common reasons for daytime sleepiness, including:
1. Bad sleeping habits
While feeling constantly tired can be linked to many factors, it all starts with getting enough sleep.
That's according to Tim Roberts, vice president of science and innovation at Therabody, a Texas-based wellness technology firm.
The first thing to evaluate when trying to create healthy and improved sleep habits should be your sleep schedule.
Consider whether you really sleep seven to eight hours.
Next, consider whether you have a sleeping environment that helps you sleep better.
2. Restlessness caused by stress
Many people have difficulty falling asleep and then wake up frequently during the night, leaving them feeling tired during the day.
Apparently, the main cause of restlessness at night is related to anxiety or stress.
It is not unusual for the human nervous system to need sensory support to relieve stress, so that it can naturally switch from the sympathetic to the parasympathetic nervous system.
The sympathetic nervous system is responsible for preparing the body for action in stressful situations. It is activated when we feel danger or stress and triggers the "fight or flight" response. This includes an increase in heart rate, faster breathing, an increase in blood pressure and an increase in adrenaline levels to prepare us for action.
On the other hand, the parasympathetic nervous system is responsible for relaxing and restoring the body. It is activated when we are relaxed and confident. Its function is to reduce heart rate, slow breathing, lower blood pressure and promote digestion and recovery of the body.
So when it is said that sensory support is needed to shift from the sympathetic to the parasympathetic nervous system, it means that relaxation and sensory stimulation techniques are needed to reduce stress and allow the body to naturally shift into a state of rest and recovery.
Implicit sensory support can include various techniques and strategies that stimulate the senses to affect the nervous system and reduce stress. These can be: deep breathing, meditation, relaxing massages, listening to soothing music, relying on relaxing scents, muscle relaxation exercises... These techniques can help to achieve a state of relaxation and balance in the nervous system.
3. Lack of vitamins
Vitamins play an important role in sleep health, however, a significant number of people do not get the right amount of vitamins from their diet.
As a result, constant fatigue can sometimes be caused by a lack of essential nutrients crucial for optimal energy production.
Sleep vitamin supplements are designed to compensate for vitamin deficiencies.
Research suggests that vitamins C and D and B vitamins may be key to maintaining healthy sleep.
In particular, vitamin D, in addition to its key role in bone health, is also involved in the functioning of areas of the brain that control the sleep-wake cycle.
4. Blue light at night
Using technology before bed can contribute to poor sleep because it presents an inappropriate environment.
Light greatly affects our sleep/wake rhythm, so if you're surrounded by blue light from your devices while you're trying to fall asleep, you may have trouble falling asleep.
Some technologies, especially those with screens that emit blue light, can be harmful to sleep.
Above all, for the experts, the key to quality sleep is finding the best methods, environments and positions for you.
If the fatigue seems to last throughout the day, it is always best to consult a doctor to determine if there is an underlying medical condition that needs attention.
