Forest Sounds for 8 hours
Forest Sounds for 8 hours is ideal for full night sleep, workday coverage, all night study session. Eight hours is the sleep standard - long enough to cover a full night's rest with margin.
Forest environments combine multiple restorative sound elements: birdsong (a safety signal — birds fall silent when predators approach, so their presence signals "all clear" after 400,000 years of co-evolution), wind through leaves (gentle broadband masking similar to pink noise), running water if present, and the general absence of artificial sound. Buxton et al.'s PNAS meta-analysis (2021) found natural sounds produced a large positive effect on positive affect (g=1.63) and significant stress reduction (g=−0.60). Kaplan and Kaplan's Attention Restoration Theory explains why: natural environments provide "soft fascination" — they capture attention gently, allowing directed attention (the resource depleted by focused work) to recover. A 20-minute exposure to nature sounds can restore cognitive function more effectively than a 20-minute social media break.
最適な用途
8 Hours — 使い方
Eight hours is the sleep standard - long enough to cover a full night's rest with margin. However, the latest research (Basner et al., 2025, UPenn) suggests that continuous sound exposure during sleep may reduce REM sleep by 18-19 minutes. For optimal results, use Softly's sleep timer to fade the sound after 45-90 minutes rather than playing through the entire night. The sound helps you fall asleep; silence lets your brain cycle through REM undisturbed.
