How Exercise Affects Sleep
Exercise can make sleep deeper and more consistent, but timing, intensity, recovery, and body temperature all influence how it affects bedtime.
How Caffeine Affects Sleep
Caffeine can improve alertness during the day, but it can also delay sleep, lighten rest, and make nighttime awakenings more noticeable.
How Alcohol Affects Sleep
Alcohol may make some people feel sleepy at first, but it can fragment sleep later in the night and worsen snoring, reflux, heat, and early waking.
How Nicotine Affects Sleep
Nicotine is stimulating and can make sleep lighter, delay bedtime, contribute to nighttime waking, and create cravings that interrupt rest.
How Sugar Affects Sleep
Sugar affects sleep differently from person to person, but late sweets, heavy desserts, hunger swings, and reflux can all influence bedtime comfort.
How Hydration Affects Sleep
Hydration can affect sleep through thirst, dry mouth, headaches, cramps, bathroom trips, temperature comfort, and morning grogginess.
How Phone Use Affects Sleep
Phone use can delay sleep by adding light, alerts, scrolling, decisions, social stress, work pressure, and clock-checking right when the mind needs fewer signals.
How Screen Time Affects Sleep
Screen time affects sleep through light exposure, content, posture, time loss, work access, gaming intensity, and the habit of staying mentally switched on.
