Sleep is a basic part of life that is often overlooked. Difficulty sleeping can affect physical and mental well-being. In episode 64 of Klao Kae Rok, Dr. Mait, Dr. Chansiri, discusses sleep and shares ideas that may help people understand their sleep habits.
Sleep problems in modern life
As technology and daily routines change, sleep difficulties are commonly discussed. Work and entertainment can take priority over rest and reduce time available for sleep. Working from home may also make a regular sleep schedule harder to maintain, which can affect sleep quality.
Possible effects of insufficient sleep
Not getting enough sleep can affect health in several ways.
Long-term health conditions
Insufficient sleep is associated with a higher risk of long-term conditions, including cardiovascular disease, high blood pressure, diabetes, and obesity.
Mood and mental well-being
Too little sleep can affect mental well-being and may contribute to irritability, mood changes, depression, or anxiety.
Rest and recovery
Sleep is a period when the body rests and repairs itself. Growth hormone is involved in growth and muscle development.
Can sleep make up for lost sleep?
Some people believe that sleeping longer later can fully make up for too little sleep. Catch-up sleep may help to some extent, but it cannot fully compensate for prolonged insufficient sleep.
Sleep debt
Repeatedly getting too little sleep can build up what is often called “sleep debt.” A small amount of catch-up sleep may not make up for all of that lost sleep.
The body clock and sleep
The body’s circadian clock helps regulate sleep and wakefulness.
Light and melatonin
Light affects the release of melatonin, a hormone involved in regulating sleep.
The circadian cycle
The body’s circadian cycle is approximately 24.2 hours and influences the timing of sleep and waking.
Factors that affect the body clock
Light, food, and physical activity can influence the circadian clock.
Chronotype: different sleep patterns
People have different preferred patterns of sleep, often described as chronotypes.
Morning and evening patterns
Examples include people who tend to wake early and people who prefer to stay up later, along with other patterns.
Changing a chronotype
Sleep patterns may be adjusted to some degree by changing habits and the surrounding environment.
Everyday factors that can affect sleep
Several parts of daily life may influence sleep.
Blue light from screens
Blue light from electronic screens can affect melatonin release and make it harder to fall asleep.
Caffeine
Caffeine stimulates the nervous system and may make sleep more difficult, especially when consumed close to bedtime.
Stress
Stress can interfere with sleep and may be associated with difficulty falling asleep or waking during the night.
Exercise
Exercise may support better sleep. Avoiding strenuous exercise close to bedtime may help.
Common sleep concerns
Difficulty falling asleep
Difficulty falling asleep can have many possible causes, including stress, some medicines, or an underlying health condition.
Snoring and waking during the night
Snoring can be a sign of sleep apnea, a condition that can pose health risks. Waking repeatedly during the night may have several causes, including breathing problems, stress, or caffeinated drinks.
Snoring and sleep apnea
Paying attention to snoring can help identify a possible risk of sleep apnea. Repeated waking during the night may also be a sign that warrants attention.
Smartwatches and sleep tracking
Smartwatches can help users see patterns in their sleep. Depending on the device, tracked information may include sleep duration, estimated sleep quality, and heart rate.
Sleep Score
Some smartwatches provide a Sleep Score intended to summarize sleep quality.
Heart rate variability
HRV (heart rate variability) describes changes in the time between heartbeats and is used as one indicator related to overall health and stress.
Pox
Some smartwatches measure Pox, described here as an indicator of the amount of oxygen in the blood.
Using technology to understand sleep habits
Sleep tracking can help users notice patterns and consider changes to their habits. It can provide information about sleep and help people understand routines and possible adjustments.
Sleep routines for different schedules
Following the body clock
Sleeping in line with the body’s circadian timing can support rest.
Irregular schedules and shift work
People with changing schedules still need good-quality sleep. Align sleep times with work shifts, adjust the schedule when shifts change, and create a dark, quiet, and comfortably cool sleep environment.
Light exposure and habits
Managing light exposure and daily habits can affect sleep routines.
Food and drinks that may affect sleep
Some foods and drinks can influence sleep. Alcohol may make a person feel sleepy at first, but it can reduce sleep quality over time.
Garmin Venu 4 and sleep tracking
Garmin Venu 4 is a smartwatch with features for tracking sleep, including sleep duration, estimated sleep quality, and HRV.
Key points
- Sleep matters for physical and mental well-being.
- Insufficient sleep may be associated with long-term health concerns.
- Catch-up sleep may not fully replace prolonged insufficient sleep.
- The body clock, light, and daily habits can affect sleep.
- Technology can help track sleep patterns, and alcohol may affect sleep quality.
- Consistent habits and a suitable sleep environment may support better rest.
Sleep difficulties can have many causes. Understanding sleep patterns and related factors, then considering suitable changes to daily habits and the sleep environment, may help people work toward better rest.
