Sleeping 8 hours and still exhausted?

The alarm clock rings. You do the math: you slept 8 hours. And it still feels like you spent the night carrying something heavy.

If that sounds like you, know that it happens to a lot of people and it almost never comes down to discipline or the number of hours.

Your body has an alarm

It’s 3:02 a.m. and you’re awake. Your heart is racing and your mind has opened the to-do list: the email you haven’t answered, the bill you haven’t paid, the “what if it goes wrong?”.

The body has an alarm, the stress response, built to protect you from real danger. It does that job well. The trouble starts when it goes off over an email, at 3 a.m., and nobody tells it the danger has passed.

An alarm that sensitive keeps you from reaching deep sleep, which is where the body repairs itself. To see why, it helps to know what the brain does during the night.

What the brain does while you sleep

At night the brain doesn’t switch off. It keeps changing frequency, moving through different states:

• Beta: alertness and mental activity. The state you spend your day in.
• Alpha: light rest and preparation for sleep.
• Theta: the transition, deep relaxation.
• Delta: deep sleep, where much of the body’s recovery happens.

In deep sleep the body repairs tissue, regulates hormones, files away memories and adjusts mood and defences. It’s the part of the night that gives your energy back.

Where stress gets in the way

To reach deep sleep, the brain has to step down in frequency, one stage at a time. If you live on alert (deadlines, worries, screens until late, a mind that is always working), the nervous system stays stuck at the higher frequencies. You’re in bed, eyes closed, with the alarm still on.

Then you get what you already know: you fall asleep late, wake in the middle of the night, or sleep all the hours without ever reaching the part that repairs.

Tiredness is the warning

Long stretches of poor sleep are linked to more anxiety, more inflammation and less energy. The tiredness you feel in the morning tells you something in the system is out of balance.

Signs your alarm goes off too often

1. You wake in the night (often at the same time) with a racing heart and a mind already at work.
2. You sleep the right number of hours and wake up without feeling rested.
3. You need a screen, coffee or noise to manage to slow down or speed up.

If this happens often, talk to your doctor to rule out clinical causes, especially if you feel palpitations or shortness of breath. Biofeedback does not replace that assessment.

Where Biofeedback comes in

Sleep is one of the most common reasons people come to me, and many tell me they sleep better over the course of the sessions. Biofeedback is a non-invasive method: it shows how your nervous system is reacting to stress and supports the body’s natural capacity for self-regulation. The idea is to help the system turn the alarm down, so rest can come more naturally.

I know what I’m talking about. I lived for years on alert, until burnout.

"I found Filipa Teixeira's Biofeedback during one of many sleepless nights... I couldn't believe that not only did I sleep deeply during the treatment, but that night and the following nights I slept more than 9 hours straight."

Biofeedback is not a medical treatment or a diagnosis, and results vary from person to person.
