These biohacks will make you feel more alert after a sleepless night

Posted by for Sleep

Despite our best efforts, sleepless nights aren’t always avoidable, especially when you take into account the fact that variables such as mood and diet can affect our ability to get quality rest. So, we asked a sleep expert how to biohack your way into feeling more alert after a bad night’s sleep. 

Welcome to The Curiosity Academy, Stylist’s new learning hub where you can access workshops, how-to guides, new research and learn the most up-to-date skills from the UK’s most in-the-know people.

The number of people in the UK suffering from bad sleep has risen from one in six to one in four, according to a recent study by the University of Southampton. Google search trends appear to corroborate the research, with people taking to the search engine to seek advice about what amount of sleep is needed to survive on a daily basis.

Sleeplessness has become a huge issue in our lives, partly thanks to the many variables that can affect our ability to relax. From overstimulation from electronic gadgets to the weather, sleep quality can be affected by a huge number of things. 

However, the feeling of grogginess we get after a restless night can have a deep impact on us, according to Dr Sonia Khan, lead pharmacist at Medicine Direct. Grogginess occurs when “the body can’t carry out the essential maintenance that it’s required to do every night,” says Dr Khan. “For individuals that do not fall into the later stages of sleep, this means that your brain effectively stays active all day and is unable to effectively process and store yesterday’s events.”

“In essence, your brain has not switched off from the previous day. Your body is also unable to repair any damaged cells and muscles to ensure there is enough energy in them for the following day,” she adds. 

No matter how many sleep hacks you try, sometimes there’s no escaping a disrupted night. Although we can’t replace the hours of lost shuteye, experts have determined that our bodies’ responses to certain stimuli can lead to an increased feeling of alertness.

Read on for three science-backed ways to fight the brain fog that follows a night of little sleep. 

Practise yoga nidra

Pulling your yoga mat out after a waking up from a long night of tossing and turning might seem counterproductive, but Risa Gabrielle, a certified sleep therapist swears by this yoga practice and says, “30 minutes of yoga nidra can feel like the equivalent of getting up to two hours more sleep.”

Yoga Nidra or yogic sleep as it’s commonly known is “a deeply guided meditation that puts you in a hypnotic and hypnagogic (between sleep and rest) state.”

Gabrielle says: “It slows your brainwaves, so you are able to experience the restorative benefits of sleep while technically still being awake. And it helps you access the parasympathetic nervous system and relaxation response. Unlike taking a nap, you don’t feel groggy when you finish a yoga nidra.”

She advises using free guided yoga nidra sessions on YouTube or the Yoga Nidra Network.

Utilise intentional stressors

Not to be confused with mental or emotional stress, physical stress involves putting the body in a situation that “positively stimulates adrenaline release. Despite feeling tired and sleepy, putting your body through its paces with a short HIIT workout, or a quick run can “give you a burst of energy in the morning.”

If you’re not huge on physical activity first thing in the morning, Gabrielle suggests taking a cold shower – start warm and then work your way up to cold, or practising techniques such as Wim Hof or Tummo breathing, can elicit the same energy high. Gabrielle explains, “The reason this works is that these are positive stressors that will increase adrenaline and cortisol levels – they’ll certainly give you energy in the short term.”

For people who suffer with chronic sleeplessness disorders such as insomnia, the habitual practice of intentional stress has long-term benefits. Gabrielle says that over time your brain starts to associate the stressor with the positive effect of boosted energy.

She explains: “What that does is helps release dopamine and serotonin, which helps the body get more out of the adrenaline release. By marrying the adrenaline and cortisol spike with the feel good-hormone dopamine, and the mood stabilising-hormone serotonin, these practices help you manage the stress response in your body in the long-term.”

Get into the light

We already know that getting out into natural light can boost your mood. However, instead of saving your daylight hour for a relaxing lunchtime walk, when chasing an early energy boost, Gabrielle suggests you “get outside within the first 30 to 60 minutes of waking up.”

Using this method to counteract the effects of bad sleep depends on timing “the body’s cortisol release so that it is strongest in the mornings. Getting this daylight also prevents a late shift in cortisol release – which correlates with anxiety, depression, insomnia.” She explains, “The right amount of cortisol in the morning helps to improve focus, energy levels and learning.”

When it comes to light exposure, it’s not just a matter of when but also of how much. Gabrielle specifies: “On a sunny day, get outside for five to 10 minutes, if it’s overcast, 10 to 20 minutes will do. On a cloudy day it takes about 30 minutes to get the right amount of daylight.”

Tips to feel more rested ahead of a restless night

If you’re working late, staying up to binge the latest must-watch or have to wake up early for a flight, there’s not much you can do to prolong your sleep. However, Gabrielle has a few tips for making whatever amount of sleep you do get feel more restful. 

  • Put all your gadgets away at least half an hour before bed. Gabrielle says, “The blue light from your phone is debilitating to sleep, but the other reason is that the content from our phone or TV can spike our cortisol and adrenaline levels.”
  • Build rest stops into your day so that bedtime is the first time you’re resting all day. According to Gabrielle, “Intentional rest helps soothe your nervous system, and gets you into that rest and digest state.” She suggests the following practices for intentional daytime rest: “Stop looking at screens for two minutes, close your eyes and scan your body and breathe; listen to a five-minute guided meditation; go for a walk without your phone; do a restorative yoga pose.”
