Sleep is a rather complex and complicated subject that a lot of behavioral scientists are still studying. This is why we’ve done all of the complex work for you and have devised a sleep calculator to help you figure out approximately what time you should fall asleep. Why are these times important? Getting the optimal amount of sleep and falling asleep at the right time can drastically improve the quality of your sleep and leave you feeling refreshed after you wake up.

We realize that sleep works differently for everyone and everyone has different contributing factors as to what kind of sleep quality they’re going to get. This is why we try to include multiple time slots in our sleep calculator to help choose a time that’s best for you, while taking the scientific evidence to provide you with the most optimal sleep possible. Never have to second guess when you should go to bed or try to get some beauty sleep.

Q: How does the sleep calculator work?A: When a person sleeps, there’s different sleeping cycles and these cycles are important to know. If you wake up in the middle of a cycle, you’ll notice that you have that hungover feeling and you’ll find it hard to get on your feet and moving. People often feel groggy, tired and stressed out when they’re awoken in the middle of a sleeping cycle. For this purpose, Howsleepworks takes the sleeping cycles and counts backwards. The ultimate goal is to help you wake up in-between the sleeping cycles which means you’ll wake up alert and ready to start the day.

Q: How long does it take to fall asleep?

A: There’s many different contributing factors to how long it takes the average person to fall asleep. However, the average person tends to fall asleep after 14 minutes of resting their head and in a state of relaxation. Again, this number can vary based on a person’s anxiety, how tired they are, their stress levels and if they’ve been consuming any amounts of alcohol.

Q: Does drinking alcohol help you fall asleep faster?

A: Yes, but not in a productive way or a way that you’d prefer. Alcohol is more of a drain on the body and its resources to make you a productive person. When you lay down while under the effects of alcohol, you’ll notice that you do fall asleep faster but the quality of your sleep is actually disturbed and you’ll get far less sleep. A lot of people report that they actually wake up far sooner than they normally would while under the effects of alcohol and they don’t get a full night’s rest. This is also leaving out the hangover and generally awful feeling you get with excessive drinking. We highly recommend going to bed sober and on a healthy meal with some glasses of water for the best sleep.

Q: How many different sleeping cycles is there?

A: This might vary from person to person but if we’re talking in general, you want to try to get 5 or 6 sleeping cycles for the best and healthiest sleep. It’s considered a good night’s sleep if you have 5 or 6 sleeping cycles but some people have less and some people have more.

Q: How can I remember more of my dreams?

A: Forgetting your dreams even immediately after waking up isn’t uncommon. The human mind sometimes tends to forget the thing or experience from the last thing we saw in a dream. There’s nothing wrong with your brain, so there’s no need to be alarmed there. Even a deep state of healthy sleeping which produces a pleasant dream can be forgotten. You’ll have several dreams throughout the night and the last one you have is the one you’re most likely to remember.

Q: Can howsleepworks improve the quality of my dreams or reduce nightmares?

A: Absolutely. While it’s not exactly known the exact cause of why people have nightmares, a lot of people speculate that it’s caused due to stress or irregular sleeping patterns. When people are on edge and stressed out, it’s not a surprise for people to somehow construct an imaginary version of real life events in a horrifying way. For example, someone feeling trapped in an abusive relationship might imagine being chased by a monster in their dream that resembles their significant other. Improving your quality of sleep will drastically help reduce nightmares and awful dreams.

Q: The calculator gave me multiple times, should I wake up at the latest one?

A: This depends but generally, you want to try not to oversleep. A healthy sleep consists of 8 hours, no matter how tired you are when you lay down. When you oversleep, you can actually wake up feeling tired again and your body takes a good portion of the day to adjust and get used to it. Sleep accordingly and try to shoot for a nice healthy 8 hour sleep according to our calculator.
