Stress, cortisol and sleep – why can't you fall asleep?

You're lying in bed, exhausted – but your mind just won't switch off. To-do lists, replaying conversations, plans for tomorrow... This isn't a character flaw. It's cortisol.

What is cortisol and why does it block sleep?

The natural cortisol rhythm peaks in the morning to energise us for the day, and drops to a minimum in the evening to allow us to fall asleep. When the cortisol curve flattens out, the body loses its ability to recover – creating a vicious cycle of insomnia.

How to naturally lower cortisol in the evening?

• → Movement during the day: Regular physical activity reduces baseline stress levels – but avoid intense exercise right before bed.
• → Breathing techniques: Methods like 4-7-8 activate the parasympathetic nervous system – your body's natural "brake".
• → Digital detox: Limiting stimulation and social media after 8 p.m. allows the nervous system to wind down.
• → Deep Touch Pressure (DTP): A weighted blanket reduces the stress response by lowering heart rate and the physical markers of anxiety.

The science behind weighted blankets

Research has shown that 63% of people using a weighted blanket experienced a real reduction in anxiety levels. The Deep Touch Pressure mechanism activates the body's calming systems, genuinely lowering cortisol levels in the bloodstream.

Stress is part of life – but managing it is a skill. Your evening ritual could be the very first step. 🌙
