8+1 ways to improve your energy levels

1. Regular sleep rhythm

Follow a regular sleep rhythm on both weekdays and weekends. In particular, waking up at the same time in the morning is important to synchronise your internal clock. Aim to get enough sleep.

2. Light lunches and regular eating

"During the working day, have a light lunch, such as a salad or soup, and remember to have an afternoon snack, such as fruit, and drink water.

3. Caffeine

"Several cups of coffee can be consumed during the working day. A few cups of coffee a day are fine for sleep, but avoid caffeine in the afternoon, after 2pm. It's also worth remembering that teas, dark chocolate, and energy drinks and colas also contain caffeine."

4. Vitamin D

"Vitamin D affects alertness and deficiencies are common. A daily dose of 10 micrograms is recommended for adults and 20 micrograms for people over 75 all year round. However, individual requirements vary between 10 and 100 micrograms. Your own vitamin D level can be measured by a laboratory test to tailor the right dose for you."

5. Exercise in a way that suits you

Outdoor exercise, especially in the daylight hours, paces your internal central clock. Avoid strenuous, especially heart rate-raising exercise for a couple of hours before bedtime.

6. Yoga or mindfulness

When recovery is in the right balance, the sympathetic or activating nervous system is able to power through the day. You can maximise what you're doing when you take a break and sleep restfully. But if your activating nervous system stays on, you won't sleep, and you'll feel tired the next day. Yoga and mindfulness exercises lower your circadian rhythms. Doing them during the day is like putting money in the sleep bank for the next night."

7. Daytime naps should be scheduled before 3 p.m

The earlier the better. The maximum appropriate duration is about 20 minutes. Too long a nap eats into the next night's sleep. If it's difficult to settle down to sleep, don't worry about it. Short periods of relaxation throughout the day, just relaxing in place, work just as well. For example, you could try the following: take a deep breath in through your nose and hold it for a few seconds before slowly blowing the air out through your mouth. Do this for a few minutes."

8. Light

Try to be outside in natural light as much as possible. Some people may benefit from a dawn or dusk light or a bright light bulb in the morning. Dim the lights in the evening and set your smart devices to night or dark mode.

+1 Investigate fatigue if necessary

"When a patient comes to my practice with problems with alertness or fatigue, I try to investigate the problem as comprehensively as possible. Investigations include laboratory tests and a mood survey. I will also ask the patient about any viral diseases they have contracted and refer them for sleep tests if necessary. Fatigue affects work performance and quality of life, so it pays to investigate its causes."
