Supporting the Mental Health of residents in Lewisham


The Daylight app offers support for anxiety issues, presenting you with practical techniques to help you learn to cope with your worry and anxiety in a different way.

It is a digital therapeutic app intended to provide Cognitive Behavioural Therapy techniques for the improvement of worry and anxiety. It should be considered if you have mild symptoms and/or are waiting for other services, such as IAPT.

Daylight is provided entirely through a smartphone app (all support is virtual) and provides four scientifically backed techniques to reduce anxiety symptoms. It is recommended to use Daylight daily. There is no waiting list so can be accessed immediately.

FAQs About the Daylight app

Who is Daylight for? – Daylight is for adults who have difficulty with worry and anxiety. Please see specific information regarding suitability here.

Can people with other types of anxiety (besides worry) use Daylight? – Individuals with other types of anxiety (e.g., panic attacks, specific fears) may also benefit from the cognitive behavioral techniques used in Daylight, as similar techniques are used for these problems. However, Daylight does not specifically focus on other types of anxiety and is primarily focused on worry.

How often should someone use Daylight? – We recommend using Daylight daily. Individuals tend to see the most benefit from utilising cognitive behavioral techniques when they are practiced regularly, and in daily life situations. Accordingly, Daylight promotes daily use of the app.

How long should someone use Daylight? – It is up to the user how long they use Daylight. Daylight users will receive weekly feedback on their progress. When they have achieved their desired goals, they can keep using the app, either as a way to practice techniques daily, or as a way to check in on their worry and anxiety weekly. In our research, we have seen that users who use Daylight frequently (approximately daily) can start to notice benefits in as little as 3-4 weeks, and that using the app frequently for up to 6 weeks may result in more benefit.

Is there anyone for whom Daylight would not be safe to use? – Please see information regarding suitability here.

What happens if a user’s worry and anxiety or other mental health concerns worsen as they are using Daylight? – Users are informed from the onset of the program (both in the program, and in a safety email that they receive upon enrollment) that Daylight is a web-based and mobile digital application that provides users with self-help tools to address worry and anxiety, and that they should contact their doctor for medical advice in the event that they feel worse. This is reiterated each time they report feeling worse from week to week.

What are the four techniques in Daylight? – The four techniques in Daylight are Tense & Release (based on the principles of progressive relaxation and applied relaxation), Worry Time (based on the principles of stimulus control), Thought Challenger (based on the principles of cognitive restructuring), and Worry Exposure (based on principles of imaginal exposure, including cognitive reappraisal and habituation).

What is Tense & Release? – Tense & Release is Daylight’s relaxation component and is designed to help with the physical feelings of worry and anxiety, including muscle tension. It is based on the principles of progressive muscle relaxation and applied relaxation, which involve learning to become more aware of the difference between tensed and relaxed muscles, and to learn how to naturally induce a relaxation response by first tensing their muscles.

Is Tense & Relief safe for individuals with chronic pain? – Users are advised, both within Daylight and on the suitability page of our website, that if they experience pain while tensing their muscles, they can modify the exercise (and simply relax their muscles without tensing them). There is also a modified practice version of this technique available that does not involve tensing the muscles.

What is Worry Scheduling/Worry Time? – Worry scheduling/worry time is a technique where users schedule a specific time and place to worry, and practice delaying worry until they are in this specific time and place. After repeated practice, users learn to restrict worry to their specific time and place, and increase their ability to stop worrying throughout the day.

What is Thought Challenger? – Thought Challenger is a technique that is based on the principles of cognitive restructuring, which involves learning how to question thoughts (e.g., examine the evidence for whether a thought is true) and gain a new perspective.

What is Worry Exposure? – Worry exposure is based on the principles of imaginal exposure. Users are led through an exercise in which they imagine the feared outcomes for a particular worry, considering how they would cope in that situation.

Why were these four techniques selected?  – The four core techniques in Daylight were selected by a panel of anxiety experts, who carefully considered which cognitive behavioral techniques were most effective for worry and anxiety, and which could be most effectively used in a digital format.
