Can Apple Watch 8 Track Sleep Accurately?

On our wedding day, my bride insists on wearing an old, beat-up watch with the million-dollar wedding dress I buy her. I call off the wedding on the spot. She looks at me in shock. "You called off the wedding just because of a watch?" I take out the divorce agreement and tell her to sign. "Yes. Because of that watch." Everyone calls me crazy. They cannot believe I would end a ten-year relationship over something so worthless and file for divorce in front of everyone. Dad walks up and slaps me across the face. "Get on your knees, you disgrace." My mother-in-law shrieks that I have ruined her daughter's future by returning her like damaged goods. I look at the watch on her wrist, which is stopped at 3:07, and I smile. Then, I phone my assistant. "It's time. Release everything. I want a divorce."

My dad always calls me a lazy bum. It is because I often fall asleep without warning. I sleep in class, while eating, and even while crossing the street. My homeroom teacher, Yvonne Smith, suggests that he take me to a hospital for an examination. But Dad scoffs and says, "He's just staying up all night playing on his phone." After that, he confiscates my phone and removes the lock from my bedroom door. Every time I get sleepy, he slaps me. I don't want to be hit, and I don't want to make Dad angry. So, I start pinching my thighs, pulling out my hair, and even rubbing hand sanitizer spray under my nose to stay awake. But whenever the overwhelming drowsiness hits, nothing can stop it. On the day of the final exams, Dad happens to be one of the invigilators. I bite my lip until it bleeds and silently beg myself inwardly, "Just this once, please stay awake." Still, I fail to fight off the sleepiness. Suddenly, someone flips over my desk. The chair tips with it, and I crash to the floor. My temple slams into the corner of the desk, and darkness instantly floods my vision. Dad stands over me, furious and disappointed. "Zach Davies, are you really so obsessed with sleeping that you don't even care about your final exams? If you're that lazy, then stay down there and keep sleeping!" I lie sprawled across my exam paper as my vision slowly fades away. Dad, I think I am going to sleep for a very long time…

Four days after my death, my four-year-old daughter finally sensed that something was terribly wrong. The fridge door slammed into her forehead when she tried to get a snack. Normally, I would've been there in a heartbeat—arms open, kisses ready, whispering, "You're okay, sweetheart, Mommy's here." But this time, I just lay on the bed, cold and still.​ She didn't understand. She thought the sweet treat would make me respond. So she held the final piece of chocolate up to my mouth. "Here, Mommy. Have some chocolate..." But I didn't even blink. She climbed into my arms, clutching my clothes tightly. "Mommy... Mommy, wake up..." She waited for me to stroke her hair, to tell her that everything was going to be fine. There was only silence.​ Completely lost and scared, she found my phone. "Daddy, why is Mommy still sleeping?" she asked, her voice filled with desperation.​ In response, Oliver sent a photo of himself having Christmas Eve dinner with his childhood sweetheart. His voice was icy cold when he replied, "She's just sleeping, not dead. It's Christmas Eve, and I'm busy. Tell her to stop playing games and come apologize when she's done sulking." Then he hung up.​ But when the truth finally hit Oliver—when the coroner's report came, when the police knocked on his door right in the middle of his laughter, when he realized I'd been lying dead for four days while he toasted—he broke.

Mom always said I was dead to the world when I slept. I would suddenly doze off in the middle of class, while eating, even halfway across the street. My homeroom teacher suggested I get checked at a hospital, but Mom brushed it off with a scoff. "She just stayed up all night on her phone!" After that, my phone was confiscated, the lock on my door was removed, and every time I showed the slightest sign of drowsiness, I got slapped awake. I did not want to be hit, and I did not want Mom to get angry, so I started pinching my thighs, yanking my hair, even downing medicated oil just to stay awake. But when that wave of sleep hit, nothing could stop it. On the day of the final exam, Mom happened to be assigned as one of the proctors. I bit through my lip, silently begging myself, 'Just this once. Just hold on.' But in the end, I still couldn't fight it. The desk was suddenly flipped over. I went down with my chair, crashing hard onto the floor. My head struck the edge of the desk, and darkness swallowed everything in an instant. Mom stood beside me, furious and disappointed. "Cecelia Thorne, are you really so obsessed with sleeping that you don't even care about your final exams? If you're that lazy, then lie there and keep sleeping!" I lay sprawled over my exam paper, my vision dimming bit by bit. Mom, this time, I might really sleep for a long, long time.

My wife, Wendy Sinclair, has a severe sleepwalking disorder. After she falls asleep, she always wanders out in a state of unconsciousness. The night before our wedding, she disappears without a word. I have no choice but to postpone our wedding. Only then does she walk out of her childhood friend's house next door, rubbing her sleepy eyes. Afraid I might overthink, she cries and apologizes to me. "There's no cure for my condition. From now on, just tie me up when I sleep, okay?" I feel sorry for her, so I just change the door lock to make sure she cannot go out. But in the middle of the night, I wake up and see her standing on the edge of the balcony. She climbs in through the window and goes into her childhood friend's house again. Soon, suggestive and intimate sounds come from inside. My blood runs cold. Her sleepwalking isn't an illness at all—it is out of love.

My husband, Matt Miller, suffers from severe insomnia. He can't stand a little bit of noise while he's asleep. After six years of marriage, I've gotten used to the quiet. I don't watch TV after 9:00 pm. I don't make calls or eat. I even walk on tiptoes. Everything feels worth it when I see him sleeping soundly. Until one day, when I go to his office to deliver some documents, I realize the door isn't tightly shut. His secretary, Faye Davis, is sitting cross-legged on the carpet while eating potato chips. A variety show is playing loudly in the background. Meanwhile, Matt is asleep on the couch. Just as Faye reaches forward to turn down the volume, he raises his hand and strokes her hair, all the while keeping his eyes closed. "It's okay. I sleep better with the noise." I stand outside the door, recalling the bad cold I had last month. Afraid that my coughing would wake him up, I had buried my head into the pillow all night. The next day, he frowned and complained, "You were breathing so loudly last night. I couldn't sleep at all. Keep it down next time." Amid the crunching sounds of potato chips and Matt's steady breathing, I slowly step back. Turns out the cure to his insomnia isn't silence, but a woman. Only that woman isn't me. I guess I won't be bothering him at night anymore.
