Chart of the seasonal variation of energy reserves: rising in summer and in January and February, declining in autumn and spring

Autumn has begun and our energy reserves are declining 🍂

The days are getting shorter. And our energy balance seems to move with the seasons.

Based on 450,000 measurement days between 2021 and 2025, we see a clear pattern: our Body Resources, in other words our energy reserves, increase significantly in June, July, August and September, and in January and February.

In October, November and December, but also in March, April and May, we see a clear decrease. The visual above this article shows this movement nicely.

This pattern describes an average. Your personal balance between strain and recovery may of course be different.

Stress costs energy. Sleep and recovery help replenish your reserves. A temporary dip is normal. But if your energy reserves keep declining, that balance deserves attention.

Autumn is therefore a good moment to pause and reflect

💤 Are you sleeping enough and waking up rested?

⚖️ Does your daily work and private life leave enough room for recovery?

✨ Are there enough moments that give you energy, such as fun, relaxation and contact with others?

How do you make sure you keep recharging during autumn too?

Through the YourOptimalYou™ programme from MentalCareDirect™, multi-day ECG measurements map your personal balance between strain and recovery, enabling targeted guidance.
