It is also important to distinguish between time in bed and actual sleep time. Someone who goes to bed at 11 p.m. and gets up at 7 a.m. has eight hours available for sleep, but time spent awake during the night reduces the total amount of sleep obtained.
If you regularly need an alarm to wake up and feel tired throughout the day, you may need more sleep or an evaluation for an underlying problem.
A practical approach is to choose a wake-up time that fits your responsibilities and then establish a bedtime that allows enough time for sleep. Maintain the routine for several weeks while observing how you feel.
If persistent fatigue continues despite adequate sleep opportunity, seek medical advice rather than continually extending your time in bed without understanding the cause.
Chapter 7: Simple Changes That Can Support Heart and Brain Health
Improving sleep does not necessarily require expensive products, complicated routines, or major lifestyle changes.
Several practical steps can help support a healthier sleep pattern.
Keep Your Wake-Up Time Reasonably Consistent
Choose a wake-up time that works with your responsibilities and try to maintain it throughout the week.
A perfectly identical schedule is not always possible, but avoiding large shifts may help stabilize your internal rhythm.
If your current routine is very irregular, adjust it gradually rather than forcing an abrupt change that leaves you severely sleep-deprived.
Get Natural Light in the Morning
Exposure to daylight after waking can help regulate circadian timing and support alertness.
A morning walk, breakfast near a bright window, or time outdoors may be useful.
The amount of light needed varies, and people with certain eye conditions or those taking light-sensitive medications should follow appropriate medical guidance.
Reduce Bright Light Before Bed
In the hour or two before bedtime, consider dimming unnecessary lights and reducing stimulating screen use.
You do not necessarily need to eliminate all screens. The goal is to create conditions that help you wind down and avoid activities that repeatedly delay bedtime.
Create a Relaxing Evening Routine
Reading, gentle stretching, taking a warm bath, or listening to quiet music may help signal that the day is ending.
The best routine is one you can maintain without turning bedtime into another source of stress.
Limit Late-Day Caffeine
Caffeine can remain active in the body for several hours. People who struggle to fall asleep may benefit from avoiding coffee, energy drinks, and other caffeinated products later in the day.
Sensitivity differs from person to person, so observe how timing affects your sleep.
Avoid Using Alcohol as a Sleep Aid
Alcohol may make some people feel sleepy initially, but it can fragment sleep later in the night and worsen certain breathing-related sleep problems.
Relying on alcohol to fall asleep is therefore not a healthy long-term strategy.
Exercise Regularly
Regular physical activity supports cardiovascular health and may improve sleep quality.
Walking, cycling, swimming, strength training, or another suitable activity can be beneficial. People who find vigorous exercise too stimulating close to bedtime can move their workouts earlier.
Make Your Bedroom Comfortable
A quiet, dark, and comfortably cool room may support better sleep.
Blackout curtains, earplugs, or a fan may help some people, depending on their environment and preferences.
These changes are not guaranteed to resolve every sleep problem, but they can make healthy sleep easier to achieve.
