Using the appliance
When to use
Knowing at what time to use the Philips EnergyUp is essential. It may
mean the difference between feeling better in a few days instead of
weeks and between experiencing benefits or experiencing none.
Follow these guidelines to understand how light affects us and when
to use the Philips EnergyUp for the best results.
Duration
Most people experience benefits if they use the appliance 20 to 30
minutes each day. It is safe to use the Philips EnergyUp longer,
provided you do so at the correct time of day. You may notice some
energizing effects of light immediately. Other effects become
noticeable after several days of regular use.
Indoor life and energy dips
If you spend a lot of time indoors with little daylight and artificial light,
you can experience the energizing effects of the Philips EnergyUp
very quickly after you switch it on.
Many people experience a natural dip in the afternoon. The Philips
EnergyUp can help you counteract this dip.
Winter blues
If you experience lower energy levels, an increased need for sleep,
and a lower mood in the dark season compared to spring and
summer, use the energy light for 20-30 minutes a day. Preferably use
it in the morning to help you start the day. You may also use it later
during the day, but do not use it in the last few hours before bedtime.
If you do, the light could delay your sleep and make you even less
energetic the next day.
