Going to bed late, waking up several times during the night or opening your eyes in the morning feeling as though you have not rested has become part of many people’s routines. Work, prolonged screen use and the desire to make the most of a little more of the day have led us to treat sleep as something negotiable. However, the body does not forget the hours of rest it loses. When a person sleeps less than they need or consistently gets poor-quality rest, they begin to accumulate what is known as “sleep debt.” It is not simply about feeling tired the next day. Over time, this lack of recovery can affect concentration, memory, mood and daily performance.
“It is not just about feeling tired, but about the overall impact on health.”
Quality also matters
Sleeping well does not simply mean spending several hours in bed. An interrupted night, taking too long to fall asleep or waking up without feeling refreshed are signs that the body is not getting adequate rest. This is why someone may believe they slept enough and still experience fatigue, irritability or difficulty thinking clearly.
Stress can make this problem worse. Persistent worries make it harder to relax and fall asleep, while poor sleep, in turn, increases tension and reduces the ability to manage emotions. This creates a cycle in which fatigue fuels stress, and stress once again prevents restorative sleep.
The medical understanding of insomnia has also changed. It is no longer viewed solely as difficulty falling asleep; what happens during the day is also taken into account, including fatigue, memory problems, difficulty processing information, poor performance and changes in mood. Dr. Harold Álvarez, medical advisor at Laboratorios Bagó, explains that sleep is one of the body’s primary recovery mechanisms. When sleep quality deteriorates chronically, hormonal regulation, metabolism, immune response and the brain’s ability to process information and manage emotions can all be affected.
Restoring healthy sleep
Recovering from months of insufficient sleep does not happen overnight, but establishing consistent habits can make a difference. A first step is to maintain regular times for going to bed and waking up, even on weekends, so the body learns when it should prepare for sleep and when it is time to start the day.
Digital habits also play an important role. Avoiding screens for at least one hour before bedtime helps reduce the stimulation that keeps the mind active and can be paired with a calming routine that creates a separation between rest and daily responsibilities. The bedroom should also support good sleep: a dark, quiet, cool and comfortable space promotes relaxation and reduces interruptions.
It is also recommended to moderate the consumption of caffeine, energy drinks and nicotine during the afternoon and evening, as well as to avoid heavy meals and alcohol before bedtime. Regular physical activity can help improve sleep quality and reduce nighttime awakenings. If insomnia persists for several weeks or occurs alongside excessive daytime sleepiness, loud snoring or pauses in breathing, it is important to consult a healthcare professional.
“Sleeping well is neither a luxury nor a privilege. It is an essential biological investment in protecting physical and mental health.”
Rest is also a form of self-care
At a time when constant productivity is often rewarded, resting can create the feeling that we are wasting time. In reality, the opposite is true: adequate sleep allows us to think more clearly, regulate our emotions more effectively and face our responsibilities with greater energy.
Taking care of your sleep does not require changing your entire routine all at once. It can begin with simple decisions such as turning off screens earlier, reducing stimulants at night, maintaining a consistent schedule and creating an environment that supports sleep. Consistency is more important than trying to make up all at once for a long period of poor rest.
