I’m a sleep expert – the reason why you wake up tired even if you’ve slept more than eight hours and how to fix it

SLEEP is a non-negotiable when it comes to leading a healthy lifestyle, and there’s a way to prevent that lingering sleepy feeling you get despite getting “enough of it.”

Addison Jarman, a life hacker, has revealed exactly why you go through the day groggy despite getting the recommended amount of sleep.

In a video shared with her TikTok followers, Jarman explained that you should be sleeping in 90-minute cycles.

“You may not be going to bed at the right time for when you have to wake up,” Jarman disclosed.

And, as humans sleep in 90-minute cycles, you will wake up feeling significantly less tired if you wake up at the end of one of the 90-minute cycles.

To do this, you simply have to figure out what time you need to wake up, then count backward in 90-minute blocks to see what time you need to go to sleep at night.

According to Psychology Today, during this 90-minute sleep cycle, a person goes through the five stages of sleep.

The first four stages, NREM, contains our non-rapid eye movement sleep, while the fifth stage, REM, is where rapid eye movement occurs.

If you’re on the hunt for more ways to get a good night’s sleep, cleaning expert Carolina McCauley shared a lavender hack along with other cleaning tips to have a restful night and wake up refreshed.

For starters, the frequency with which you change your bedding will largely impact your sleep.

McCauley recommended washing them once a week to achieve ultimate freshness and make them optimal for sleep.

You can add a dash of lavender essential oil to your bedding when you wash it to promote a peaceful night of sleep, as the calming scent can relax the nervous system.

It will help you fall asleep fast and stay asleep longer.

The cleaning buff also covered the cleanliness of your mattress.

As you remember to change your bedding, be sure to give your mattress a vacuum to get rid of unhealthy dust buildup.

Lastly, if you have tech and gadgets in your room, it was suggested to completely remove them.

When it comes to your TVs and larger items though, you can cover LED lights that give off more light than you might imagine.
